Drawing of one module of a Portable Farms® Aquaponics System – 1.5m x 12m (5’ x 40’) Grow
Table. This one module feeds eight people and requires less than 10 minutes of maintenance
per day to feed the fish, plant seedlings and harvest vegetables. A 30m x 30m (100′ x 100′)
greenhouse structure with 30 separate module units and produces 80,000 vegetables and
10,400 kg (23,000 pounds) of fish per year.
This technology can be operated by women or men who are considered semi-skilled or
unskilled labor. This one aquaponics module (picture above) can grow most common table
vegetables (greens and some blooming plants such as tomatoes, peppers, cucumbers and
beans). Plus, it also raises aquatic animals, fresh water/warm water fish, such as tilapia or
catfish. These fish are harvested in between 7 and 9 months when they reach 0.5 kilos (1.25
pounds) (yields two 114g / 4-ounce fillets).
One commercial sized Grow Table of 18.5m2 (200 sq. ft.) plus 1500 liter (400 gallon) Fish Tank
and one Clarifier is considered one module. In this well-designed aquaponics system with
crushed gravel as the medium base, a Grow Table space of 18.5m2 (200 sq. ft.) feeds eight
adults their table vegetables year round – FOREVER. The Grow Table and Fish Tank may be
constructed with local materials such as lumber and locally obtained food grade rubber plastic
commonly used for livestock watering troughs. The Grow Tables and Fish Tanks may also be
made from cement.

There have been over 300 different varieties of plants (also referred to in this report as ‘table vegetables’) that have been tested and can be grown successfully in a Portable Farms® Aquaponics Systems.
The major food groups that are not recommended for Portable Farms® are root vegetables (carrots, potatoes, onions, etc.) and field crops such as corn, wheat, soy or rice. Perennial plants (strawberries, blackberries, asparagus, etc.) are not recommended because the plants are dormant many months each year and do not produce harvestable food year round. Plus, we recommend growing all plants from seeds and not bringing in plants raised in soil into the structure which can introduce pathogens that can harm the other plants in the structure.

Introduction
The PFAS LLC Locally Grown Food & Jobs Creation Program (LGF-JCP) is focused on two very
different and closely related problems facing the world today:
1. The need to produce high quality, locally grown, pesticide-free food, and,
2. To create permanent fulltime jobs for women or men, semi-skilled or unskilled workers.
Implementing a decentralized food production system using cutting edge hyper-productive
food growing methods is the key to a successful project resulting in sustainable installations
that also generate a very respectable ROI for the donors or investors excluding land costs.
In line with the United Nations Conference on Sustainable Development and goals in the
“Future We Want,” the ideas outlined in this report support the UN’s initiatives and
commitments to sustainable development, creation of economic opportunities, skills and
apprentice training, stopping the cycle of poverty and feeding the world:
1) “We, the Heads of State and Government and high-level representatives, having met at
Rio de Janeiro, Brazil, from 20 to 22 June 2012, with the full participation of civil society,
renew our commitment to sustainable development and to ensuring the promotion of
an economically, socially and environmentally sustainable future for our planet and for
present and future generations.
2) Eradicating poverty is the greatest global challenge facing the world today and an
indispensable requirement for sustainable development. In this regard we are
committed to freeing humanity from poverty and hunger as a matter of urgency.
3) We therefore acknowledge the need to further mainstream sustainable development at
all levels, integrating economic, social and environmental aspects and recognizing their
interlinkages, so as to achieve sustainable development in all its dimensions.”
By selling a large portion of the vegetables and fish grown in Portable Farms® Aquaponics
Systems (PFAS) to local high end markets, the aquaponic’s installations become self-
sustaining. These sales are necessary to pay for ongoing costs of operation, salaries, seeds and
seed supplies, fish and fish food, utilities and ancillary costs associated with maintenance.
Selling all or most of the food grown in Portable Farms® Aquaponics Systems (PFAS) offers
donors or investors a 3 to 5-year ROI depending on the crops grown and the prices received.

Using proprietary Portable Farms® Aquaponics Systems (PFAS) technology and design, each
2.5m2 (25 square feet) of grow space can feed one adult all of their table vegetables, except for
root vegetables (potatoes, yams, onions and carrots, etc.) year round and once up to full
production about 20% of their protein requirement, forever. These people will also need some
other starches/carbohydrates in their diets such as ‘field crops’ as wheat, potatoes, soy, corn or
rice. These starchy foods are generally available and less expensive than table vegetables.
This 4.9m x 10m (16’ x 33’) Portable Farms® Aquaponics Systems (PFAS) can feed ten people most of their table
vegetables and some of their protein requirement year round and provides 18.6m2 (200 sq. ft.) of growing
space.
In addition to growing high quality, pesticide-free, locally grown food, this program is
specifically designed to create jobs in each location. After the initial installation, each
additional 1,000m2 (10,000 sq. ft.) installation creates three permanent full-time job and leads
to the creation of additional indirect jobs in support services, supplies and ancillary work
including areas related to maintenance and utilities, food packaging, fish processing,
community relations and marketing, personnel oversight, bookkeeping and security.
Whether the displaced persons or asylum seekers are placed in urban or rural locations, the
availability of locally grown food and jobs remains a vital decision to be made by those funding
the projects since the world population is expected to reach beyond its limitations for providing
both food and jobs by the 2030 projections by the United Nations.

In the twenty-first century, the world faces an environmental crisis, issues related to displaced
peoples from regional conflicts, climate change (drought and flooding as well as record-setting
heat waves) and an energy crisis. Also, many parts of the world face severe food shortages.
Twentieth century agricultural techniques have harmed the environment and consume an
inordinate amount of energy and water. Many countries lack the large amounts of arable land
and water needed to sustain their growing human populations. Developing nations use large
amounts of pesticides and artificial fertilizers to grow their grains, fruits, and vegetables. At the
same time, they use huge amounts of gasoline, natural gas and diesel fuel to power their farm
machinery, produce electricity to process their food, and enormous amounts of fuel to ship the
processed food to grocery stores. The raising of farm animals, particularly cattle and swine, is
notoriously inefficient in terms of the amount of land and energy required to raise corn and
other animal feed for each pound of protein produced.
With increasingly volatile weather conditions, bigger storms, heavier rains, and more intense
droughts, aquaponics offers easy solutions that outweigh issues related to traditional
agriculture. Climate change effects not just food prices, but also food availability. Although not
all vegetables can be grown using the PFAS, it has been successful in growing over 300 varieties
of produce that are larger, more flavorful and more nutritious than those found in most stores.
Unless the food production paradigm is changed quickly, many countries of the world run the
increasing risk of domestic food shortages that often spark the kind of riots and social chaos
played out around the world.
With the population growth the projected at 9.1 billion in 2050, there must be a shift towards
vegetarianism and the option for farm-raised fish as a protein source for many, and a shift away
from meat-heavy diets, but this will take time.
In a 2009 report by The Food and Agricultural Organization of the United Nations (FAO),
Global Agriculture by 2050, states, “The projections show that feeding a world
population of 9.1 billion people in 2050 would require raising overall food production by
some 70 percent between 2005/07 and 2050.”
February 2014, “Fish to 2030: Prospects for Fisheries and Aquaculture,” a collaboration
between the World Bank, Food and Agriculture Organization of the United Nations
(FAO) and the International Food Policy Research Institute (IFPRI) stated, “ . . .
aquaculture, fish farming, will provide close to two-thirds of global food fish

consumption by 2030 as catches from wild capture fisheries level off and demand from
an emerging global middle class, especially in China, substantially increases.”
In 2014, the United Nation’s Report on World Urbanization Prospects stated, “Globally,
more people live in urban areas than in rural areas, with 54 percent of the world’s
population residing in urban areas in 2014. In 1950, 30 percent of the world’s
population was urban, and by 2050, 66 percent of the world’s population is projected to
be urban.”
Today, the transportation costs of food delivery account for up to half of the cost of some food
items. By removing the impact of transportation on the cost of food by growing food locally,
PFAS LLC’S Locally Grown Food & Jobs Creation Program (LGF-JCP), immediately makes onsite
food production profitable as farming and transportation equipment costs continue to escalate
over the coming years in addition to the increased amount of food required to feed a growing
population in urban areas.
The carbon footprint of each Commercial PFAS Installation can often be reduced to a negative
value through the use of solar power because the electrical requirements are lower than any
other aquaponics technology currently available in the world today. The electrical needs are
highest during the daylight hours and are minimal during the night. When placed in climatically
adapted structures that allows the temperatures to fluctuate over time, the energy
requirements are kept to a minimum. Solar power is now an economical alternative and in
most cases more reliable than local grid power.
The PFAS LLC Locally Grown Food & Jobs Creation Program (LGF-JCP) can be structured several
ways to match the needs of the governmental agency, organization, institution or investor. It
can be a one-time installation, an ongoing building project, a territorial expansion of the
technology or even a country-wide program to increase food supplies and reduce joblessness.
It can be a multi-phase project beginning with major urban areas in a country/province/state
and spread over five years or a longer period. The funds generated by the operations and any
additional follow-up funding can be used to fund further expansion. See INVESTMENT
PACKAGES below for the impact of each level of funding.

Controlled Environment Agriculture (CEA) is a global trend that allows year-round and state-of-
the-art and food production because of the multitude of advantages for controlling the growing
environment for maximum production yields. These include:
Extended growing season – often year round
Greatly reduced consumption of water even with in-ground growing methods
Less expensive and more accurate pest control – often pests are eliminated as a
problem
Ability to control light, humidity and temperature
The opportunity to install grow lights for extended growing seasons for growing a wider
variety of crops, especially important for blooming plants such as tomatoes, peppers,
cucumbers, etc.
Makes solar energy a viable option to enhance reliability and reduce carbon impact
Less chance for crop losses due to weather, pests, water loss, and theft
Efficient use of organic nutrients for maximum production.
The Portable Farms® Aquaponics Systems (PFAS) are always installed in climatically adapted
structures (greenhouses or with the additional use of grow lights, a warehouse) without the use
of soil, pesticides or chemicals. The PFAS use less than 1/10th the amount of land and from 90
to 95% less water than traditional agricultural growing techniques, and produces both fish and
vegetables year round, regardless of the climate. The installations are low-tech and do not
require heavy machinery or significant infrastructure to build or operate. The PFAS has the
lowest energy requirements of any aquaponics systems currently available.
The PFAS LLC Locally Grown Food & Jobs Creation Program (LGF-JCP) also trains local workers
to build the Grow Table Modules and trains the Operators in the most effective methods of
operating the installations. Operators can be trained in less than one week.

Overview of aquaponics
Aquaponics is the combination of aquaculture (fish farming) and hydroponics (growing plants in
water only), in a carefully designed, hyper-productive closed-loop system. In addition to
producing large quantities of food, the LGF-JCP creates permanent full-time jobs for women or
men, unskilled to semi-skilled laborers using a low-tech, high-intensity food production
method. This program creates a dispersed food production facility on both a macro and micro-
scale.
Portable Farms® Aquaponics Systems relates to agriculture and more particularly, to the
farming of aquatic animals and the use of their waste as fertilizing nutrients to grow
vegetables in a closed loop recirculating system.

Many areas of the world, such as California, require elaborate and expensive aqueducts and
irrigation systems to deliver potable water to farming regions. Extensive irrigation has lowered
ground-water tables in some areas so dramatically that ground water is no longer available. A
tremendous amount of fresh water evaporates or is otherwise wasted with conventional
farming methods. Developing countries often lack the financial resources, arable land and
technology to produce sufficient food, and in particular, they lack enough protein to maintain
the health of their human populations. There are also health concerns raised by humans
consuming pesticide residues on fruits and vegetables and hormones in chicken, pork and beef.
Wild birds and animals are adversely affected by pesticide and fertilizer. Local waters (ponds,
rivers, and streams) are also polluted by the runoff from the pesticides and fertilizers used for
local growing.
There is a need to promote a new "green" and sustainable methods of farming around the
world to create ‘locally grown food’ in any region to produce healthier food that requires far
less land and water, and at the same time, is environmentally friendly by employing the use of
aquaponics systems to feed people healthy food.
Aquaponics:
• Eliminates the need or use of artificial chemicals or pesticides
• Provides sustainability for people locally
• Substantially reduces energy consumption for planting, harvesting and shipping food,
and greenhouse gas emissions
• Also, provides jobs for local people thereby strengthening the local economy for
expanded community business opportunities such as restaurants and shops.

Aquaponics has been explored for several decades as a possible solution to the future for
improving the environmental and solving the problems of food shortage problems. Aquaponics
combines the art of growing aquatic animals (fish), known as aquaculture, with the modern
technology of hydroponics in which plants are grown without soil. In aquaponics, fish and
plants are grown together in an integrated closed loop recirculating system with a very low rate
of water usage or water loss due to evaporation. The fish waste (effluent) produced by the fish
is delivered from the fish tank to a settling tank to remove the heavy ‘waste’ and then sent to
the Grow Tables to provide a food source for growing plants in the gravel and the plants
provide a natural filter for the water that keeps the fish healthy. This symbiotic relationship
between the fish and the growing plants is the goal of aquaponics by creating a sustainable
ecosystem in which both fish and plants can thrive and as a result, produces safe, fresh protein
and healthy vegetables. The addition of a tiny amount of a fish friendly organically certified
(USDA in California) mineral rock dust is necessary for blooming plants to be fully productive.

The average height of each plant of kale is 1.2m (47”) tall.
Aquaponics systems heretofore developed have not met with widespread success. Previously,
aquaponics systems have been complex and labor intensive to operate, difficult to construct
because to date, there has been no standard design that has proven to be easy to operate, and
they are often poorly constructed with inferior materials requiring constant attention to leaks,
challenges for disposal of the fish waste, and careful maintenance of pH levels, micronutrient
depletion and water temperature. They have also been expensive in terms of the pumps and
other electrical equipment required. Also, prior aquaponics systems have been difficult to
maintain and are prone to catastrophic system failures such as the death of the fish and plants
due to design flaws in the actual aquaponics system.

Portable Farms® Aquaponics Systems provides improvements over all prior aquaponics systems
that have been fraught with fragility and difficulty in maintaining a healthy balance between
each of the components and the living systems. In particular, Portable Farms® Aquaponics
Systems improve waste removal from the aquaponics system, provides an improved pump to
the aquaponics system, and provides an improved Grow Table design and uses less power than
other existing aquaponics systems.

Overview of Portable Farms® Aquaponics Systems
The Fish Tank of the Portable Farms® Aquaponics Systems contains the water and the fresh-
water fish that provides the nutrient-laden wastewater for the growth of the plants in the Grow
Table. Periodically (generally twice per day), a portion of the water is automatically removed
from the Fish Tank by the use of a uniquely designed submersed air-powered pump and
transported via pipes to a clarifier located above the Fish Tank. Lifting the water from the Fish
Tank to the clarifier is the only time energy is required to move water in the Portable Farms®
Aquaponics Systems with gravity powering the remainder of the water-flow cycle. After the
water has been delivered to the clarifier, the solid waste then settles to the bottom of the
clarifier due to a dramatic reduction in the velocity of the water flowing into the clarifier. The
water overflowing out from the clarifier is free of the solid waste matter and flows from the top
of the clarifier through a conduit pipe to the Grow Table. This clarified water is now distributed
under the gravel to fill the Grow Table to a predetermined level (much like a bathtub, it rises
evenly across the entire table). Once this predetermined water level has been attained, an
automatic valve assembly under the gravel in the Grow Table allows the water to completely
drain from the Grow Table and return to the fish tank stripped of the nutrient load by the
plants and re-oxygenated by the large surface area of the gravel and leaving the plant roots
exposed to the ambient air for maximum growth.

Portable Farms® Aquaponics Systems (PFAS) require no chemical fertilizers or
insecticides in the growing of the food.
PFAS eliminates the possibility of catastrophic system shut down because there is no
single point failure in the system and in times of short-term power outages, they can be
operated manually, without electrical power.
PFAS begins to provide healthy produce approximately twenty-eight to forty days after
installation.
The system provides a protein source (fish) within seven to nine months after the
system is operational. In one embodiment, Portable Farms® Aquaponics Systems is
capable of feeding eight people with the labor of one person working only 20 minutes
per day. This size Portable Farms® Aquaponics Systems requires only 1 kwh per day of
electricity (powered by any available electrical source), per module that feeds eight
people. In another embodiment, Portable Farms® Aquaponics Systems is capable of
feeding 240 people with the labor of three people working full time.
PFAS uses a minimal amount of potable water for food production (the water
requirement is reduced by 90 to 95% compared with conventional farming).
PFAS is capable of providing fresh locally grown food and food security for families,
groups, and cities.
PFAS can provide local jobs for women or men, semi-skilled labor.
Also, Portable Farms® Aquaponics Systems’ Technology Kits can be easily shipped
anywhere in the world and be assembled using mostly local materials and operated by
women or men, semi-skilled labor.
The Grow Tables never have to be cleaned, only the residual roots removed at harvest
time.
PFAS can be assembled and operated as a carbon negative installation.
Our Approach
Commercial-sized PFAS Units are normally built as 1,000m2 (10,000 sq ft) installations or
smaller, producing 9,000k (23,000lbs) of fish (Tilapia, catfish, carp or other fresh water, warm
water fish that are local favorites) and 70,000 to 200,000 vegetables per year depending on the
type and variety of plants selected and grown on the 1,000m2 (10,000 sq ft) footprints. Because
the Grow Tables are built 90cm (36 inches) above the ground, the land used for the systems can
be installed on abandoned lots, lots waiting to be ‘built on’ in the future (PFAS structures are

not permanent and can easily be moved), parking lots, or even areas where houses or buildings
were destroyed. The Grow Tables contain crushed gravel, so no soil is required. The fish waste
acts as the fertilizer for the plants, and a climatically adapted greenhouse allows for 3 to 10
harvests of greens per year (depending on the type of plants) versus the average 1 to 3 harvests
in traditional and seasonal farming. The initial markets addressed by the LGF-JCP are high-end
restaurants, casinos, resort hotels, high-end supermarkets, institutions, organizations, prisons
and schools. The fast growing and very discriminating market of the expanding middle class is
demanding the best food money can buy and are willing to pay for that type of food. They want
locally grown, pesticide free food. This market is expanding so fast it can never be satisfied in
any location in the world and institutions are always looking for ways to reduce their food costs.
This program was not initially designed to provide food to feed economically disadvantaged
people, but to give them the opportunity for permenant fulltime employment which then
provides opportunities for better nourishment, better housing and to assist in their children's
education. Instead of 'giving them a fish, they can be hired to raise fish and vegetables.'
Tilapia are harvested between 7 and 9 months when they are 27cm (11”) in length and weight 0.56k (1.25 lb.
Fish hatcheries can be established by installing small breeding tanks near the aquaponics systems. 6 females and
one male produce up to 30,000 fry per year. High protein and floating fish ‘feed’ for aquaponics is now available
and is packaged for global distribution and immediate delivery.

In addition to growing the highest quality, pesticide-free vegetables, PFAS produces large
quantities of top-quality fish, which provides a very healthy source of high-quality protein. For
example: A 30cm (11 inch) tilapia yields two 113g (4 oz) tilapia fillets each with - 105 calories, 1
gram fat, 23 grams protein compared to a 113g (4 oz) skinless chicken breast - 140 calories, 2
grams fat, 33 grams protein.
Tilapia fillets
The PFAS can use Tilapia, catfish, and several other species of fish as the nutrient source. Tilapia
is a white-fleshed fish with good texture, is easy to cook, and does not taste "fishy." Tilapia and
other whitefish species are popular fish of choice for people who order fish at restaurants.
Tilapia is the 4th most popular seafood in the US.
In the first six months of 2013 total tilapia exports from China reached 161,200 tonnes, 7%
more than a year earlier. In value, Chinese tilapia exports were higher by 11% with a value close
to USD 543 million. (Chinese tilapia and other fish should not be eaten because they are known
to contain high levels of toxins, heavy metals, antibiotics and other equally unsavory items).
According to FAO Globefish reports, “Tilapia farming is gaining more attention worldwide,
particularly to supply local demand in regions where local production is possible. Although
production from the largest producer, China, is reported to have declined since the start of this
year, increased supplies from other producers worldwide are keeping the market firm.”

The PFAS Technology consists of a series of Modules each containing a Fish Tank, a Clarifier or
Settling Tank and a Grow Tray built out of wood (they can also be fabricated out of fiberglass or
concrete), lined and filled with gravel, as can be seen in the diagram on the top of page 17
(below):
One module of a Portable Farms® Aquaponics system. The normal size for one module in a
commercial sized farm is 1.5m x 12.1m or 1.8m x 9.75m (5’ x 40’ or 6’ x 32’)
A commercial PFAS Unit of 1,000m2 (10,000 sq ft) consists of 30 Modules lined up, side-by-side
in a climatically adapted structure. Once built, the system is easy to maintain, but the
components have to be assembled with precision, or the systems will not work properly. PFAS
LLC offers a complete package that trains the workers in constructing the Modules and in the
Operation of the systems. This is part of the PFAS Commercial Program Agreement. The local
labor force is taught by a leading craftsman and instructor at each initial location. These newly
trained people can, in turn, pass along these skills to others coming into the industry.
The initial funding will be allocated for building commercial a 1,000m2 (10,000 sq ft) Unit in
specific locations. Each 1,000m2 (10,000 sq ft) facility can feed 240 adults most of their table
vegetables, indefinitely. In addition, each 1,000m2 (10,000 sq ft) facility creates multiple jobs.

Company History and Bios
When PFAS LLC began offering Portable Farms® Aquaponics Systems to the public market (after
research that began in 1971) with their PFAS in June 2008, they started with a single press
release that drew over 4,000 visitors from all over the world to the headquarters in San Diego,
California, location within its first year. To date, PFAS LLC receives over 1,000 commercial
aquaponics inquiries from over 140 countries per month.
The PFAS technology has since been simplified and systematized so the PFAS can be operated
by women or men, semi-skilled labor and require very low maintenance for their operations.
The majority of the operator's time is taken up with harvesting food and planting seeds and
small seedlings. To read more about the history of PFAS LLC: CLICK HERE.
PFAS LLC has created two courses that teach people learning how to assemble, maintain
and operate the technology for Portable Farms® Aquaponics Systems by creating and
operating a learning division for their company, Aquaponics University: CLICK HERE.
PFAS LLC offers monthly newsletters to over 50,000 subscribers worldwide. Link to 60
monthly newsletters published since April 2012: CLICK HERE.

Aquaponics Systems for the past 43 years.
After a career as a successful entrepreneur, businessman and consultant,
Colle has always made the time to continue his research to reduce the
chronic problems of tank sediment, and he discovered a new pumping system that solved all
the clogging problems in the fish tank and made it possible for the system to automatically
remove the sediments from the fish tank without clogging the pump to grow healthier fish and
vegetables. This new system made it feasible to fully automate the farm using his own unique
engineering, so that anyone, anywhere, could raise their own food. COLLE DAVIS’ EMAIL.

LANE MCCLELLAND AND LAURIE ROBERTS purchased their first
Portable Farm in 2008 and installed it at the San Diego County Fair in
2009 as the central focus of their exhibit about sustainable backyard
food production winning several awards as well as introducing the
public to Aquaponics. Lane’s construction experience
(www.1888twigman.com), Laurie’s horticultural background and their
shared enthusiasm for the Portable Farms® Aquaponics Systems, led
them to become professionally involved in the company over the last six years. Lane is the only
Certified Installation Instructor and Construction Supervisor, which has taken him to Botswana
and Nigeria to install commercial Portable Farms® Systems. His problem-solving ability,
construction background, and humor are highly valued by the Portable Farms® Family.
Laurie was part of the ‘back to the land movement’ in the early 70′s during which time she learned about growing food, building shelter, and artistic metal sculpting that supported her until hers. She went back to college for her BS degree in Environmental Design from Cal Poly and started her own design/build Landscape Company which specialized in native plant and drought tolerant gardens. This last decade, she developed a self-watering raised vegetable growing system called the ‘Earth Tanks’ which have been installed in 20 schools throughout the San Diego region. Most recently, she served as Project Manager, co-editor and photographer for the recently published ‘Baja California Plant Field Guide.”

Potential Obstacles
The main obstacle normally sighted is the lack of availability of land in most population-dense
areas. However, with the flexibility in sizing the PFAS Units and with no soil requirements, the
quality of the land acquired is much less critical as a limiting factor. As long as the lot is
relatively level and flat, a PFAS Unit can be placed on it. Also, the land in most cases can be
leased to reduce capital investment. Nearly any open or vacant lot can be used until the owners
are ready to build on it.
Revenue Sources
Portable Farms® Aquaponics Systems produces both fish and produce. The easiest to raise,
healthiest and most preferred fish to cultivate is Tilapia. Depending on the location, fresh tilapia
retails for between US$2.30 per pound (US$4/k) and US$4.50 per pound (US$8/k). The 1,000m2
(10,000 sq ft) commercial Units produce 23,000 lbs (9,000k) of fish per year, which equals
US$52,900 to US$103,000 of revenue per 1,000m2 (10,000 sq ft) facility, if sold at retail.
When adding in the economic value of 70,000 to 200,000 vegetables per year, that translates
into another US$160,000 to US$290,000 of revenue per Unit! Operating costs, including water,
electricity, and labor, average between US$85,000 and US$120,000 per year. Depending on the
mixture of food produced, the PFAS Units Return on Investment, dependent on crops grown
and local produce prices, can be in three to five years.
Because the food is locally grown in abundance on a small amount of land, without fertilizer or
pesticides, or the need for long distance transportation, the cost of delivery is much lower than
conventional farming methods and traditional organic farming methods. The lower cost basis
combined with an increase in production are the keys to maximizing profitability. Also,
because of the low maintenance costs of the grow units and non-reliance on petroleum-based
products, this food production method is unaffected by inflationary pressures.

This 1,000m2 (10,000 sq. ft.) commercial installation for Portable Farms Aquaponics Systems
is located in Botswana, Africa. ENDORSEMENT FROM FARM OWNER: CLICK HERE.
These aquaponics systems can be installed in as little as two to four weeks and can be
producing food in as little as five weeks more. The systems are simple, modular, and relatively
inexpensive and can be operated by women or men, unskilled or semi-skilled labor, while being
placed on nearly flat land anywhere in the world.
These systems are very scalable, easy to implement and a universally valuable solution to food
production. It is a carefully designed mini-ecosystem under a roof that can produce large
amounts of food year round, averaging 9,000k (20,000 pounds) of fish and 70,000 to 200,000
vegetables per 1,000m2 site. These systems can be quickly built in densely populated urban
areas, orphanages, hospitals, schools, refugee camps, and areas stricken by severe drought or
major natural disasters. PFAS LLC can assist in setting up on-site operations within two weeks
and harvesting the first crop of a permanent supply of vegetables in 4 to 6 weeks after that,
regardless of the climate or soil conditions.
The PFAS Installations are ideal for areas of urban renewal. They create local jobs and a supply
of locally grown food. Because the structures are normally classified as non-permanent (no
poured footer), they can be built as a temporary structure on a leased property. There is no
toxic waste water disposal requirement and solar energy can be used instead of being
connected to the electricity grid or the local utilities, because all the energy can be generated
on-site and rainwater can be used in many cases for the water supply.
The most robust, most scalable aquaponics system in the world is the Portable Farms®
Aquaponics System. The technology is proprietary and has already drawn interest from some
of the leaders in the food production industry.

BUSINESS STRUCTURE
The PFAS Technology Package comes with a large number of benefits including on-site training
for the construction crews, online and on the job training for the Operators, updated
technology developments as they become available, the right to build installations for other
investors or buyers within a designated territory (after successfully operating a commercial
PFAS Unit for at least one year) as a major source of revenue, the sale of new installations often
includes a service and operations contract that adds to the income stream and creates
additional jobs. These additional revenues add to the profits and can be used to fund further
expansion.
The standard commercial PFAS Unit of 1,000m2 (10,000 sq ft) consists of 30 growing
Modules, with each Grow Table having its own 1500 liter (400 gallon) fish tank. This is a
very different design from the conventional approach of having on single, very large fish
tank in a commercial facility. In fact, the pumps and design used in the commercial PFAS
facilities are exactly the same as the ones in the family sized units, except the
commercial units have 30 Modules lined up side-by-side to limit any impact of single
point of failure.
With the PFAS Technology Program, one crew of 4 full-time workers can build 30 PFAS
Modules in less than a week once the climatically adapted greenhouse structure is
nearly finished. The entire commercial unit can be completed within 2 to 4 weeks and 4
to 6 weeks later the operators can be harvesting a wide variety of lettuces, kale, Asian
greens such as bok choy, and most green leafy plants such as Swiss chard, basil, many
herbs, and more. Then, 10 to 12 weeks later, the harvesting of tomatoes, cucumbers,
zucchini, all varieties of peppers, green beans, peas, kohlrabi, and broccoli can begin.
Please note, in order to grow blooming plants in winter months (October to April in the
Northern Hemisphere) within an acclimatized greenhouse with short days and low levels
of sunlight, grow lights must be installed above the grow trays for the plants to ‘blossom
and set’ to produce food.
Economies of scale set in quickly lowering the construction costs of each unit as the
Program progresses. A single 1,000m2 (10,000 sq ft) facility can produce over 80,000
tomatoes per year. However, with a higher level of investment ($1 million) the reduced
cost per Unit quickly demonstrates the economies of scale driving the cost per Unit
down to the point that three to four 1,000m2 (10,000 sq ft) commercial facilities can be

built with the US$1.3M and giving permanent employment to 20 people while growing
800,000 plus of tomatoes per year (as an example), all this in the very first year of
production.
As stated earlier in this report on Page 4, by selling a large portion of the vegetables and fish
grown in Portable Farms® Aquaponics Systems (PFAS) to the local high end markets, the
installations can become self-sustaining.
The target markets in nearly every instance will be one or more of the following:
1) High-end Restaurants & Hotels
2) Casinos – The very best buyers because their clients demand the best food
3) Hospitals and Assisted Living Centers
4) Prisons and institutions
5) Specialty Food Markets & Organic Grocery Stores
The first tier of customers is high-end restaurants, casino and hotels who pay a premium for
locally grown, pesticide-free produce. The ability to deliver boxes of freshly harvested, locally
grown, vine-ripened produce and pounds of the freshest locally grown fish every single week,
year round is a very compelling offer. No one can compete with that, not even a major food
services type wholesale distributor.
The second tier customers are hospitals and assisted living centers that normally pay nearly full
price. The third tier are prisons and institutions that often have labor available and nearly
always go for the most affordable food they can buy. This market is enormous but needs a
slightly different approach. The fourth tier of customers are the specialty food markets like
Whole Foods and Fresh Market plus the general grocery stores that pay wholesale prices,
although organic wholesale still demands a 25% to 40% premium over conventional wholesale.
Concerning selling the fish, in most cities, there is a demand from local ethnic restaurants who
will buy them ‘whole,’ and sometimes ‘live and still swimming.’ The same markets noted above
will buy the fish if it can be processed. This adds more jobs and adds a revenue stream to the
project.

This food distribution model plan has been carefully designed to work in the urban settings of
both developed nations and developing nations, ensuring an excellent return for investors. The
time to break-even on each unit depends upon the vegetables and fish produced, but it is
anticipated that an average three to five year ROI is normal.
A 3m x 4.5m (10’ x 16’) Portable Farms installation
The backyard Units (smaller Portable Farms® Aquaponics Systems) are not as cost effective
because the cost of building the greenhouse is difficult to offset with productivity from only one
or two Grow Tray Tables. However, efficiency is achieved at the 300m2 (3,000 sq ft) size facility
and higher. These smaller facilities can be built for community groups who desire a highly
efficient year-round community garden.
Due to the cookie-cutter, modular nature of the PFAS approach, the operations can be scaled
up very quickly. The only real bottlenecks are the start-up financing for the initial construction
costs, securing suitable land and the speed of training the new project managers.
The goal of the Locally Grown Food & Jobs Creation Program (LGF-JCP) is to establish a
decentralized, distributed food production model. The break-even point on the commercial
facilities is reached very quickly and with ongoing demand for high-quality food, the program
can weather most problems and downturns.
With the Commercial PFAS Units, production typically increases by 20% after the first year
because the Grow Tables have “cured” i.e. and the beneficial bacteria that convert the nitrates
into nitrites are at their optimum levels and all the planting and harvesting cycles have been
established. The projections below are based on the minimum productivity levels. The Revenue
Projections are based on actual operating experience over the past 4 to 5 years (the lowest
possible output from the PFAS Module for each crop is shown. The actual output from each
Module can, and probably will be, from two to four times as high, so these numbers are
extremely conservative).

Please see Exhibit A which covers the Capital and Operating Expenses and the Revenue
figures which are accurate to the best of our knowledge as of September 2015.
Investment Packages
Using the figure demonstrated above here are the various level of investment and the expected
ROI on each:
A US$285,000 to US$325,000 investment will purchase a PFAS Commercial Package for
one full-size unit complete and operational. NOT INCLUDING LAND COST or GROW
LIGHTS. This is a turnkey price and includes all the on-site training for the assembly of
the Modules and the training of the operators. The ROI on the first Unit is normally
between two and three years. The second and subsequent Units cost significantly less,
in the range of US$235,000 to US$250,000 each. By the time the third or fourth Unit
comes on line, the cost may be down to slightly less than US$210,000 each. That makes
the ROI on these later Units closer to two years.
A US$1.3M investment will purchase an Expanded PFAS Commercial Package (one
acre/.45 hectare) and have the first three to four full-size Units operational. This is a
turnkey price and includes all the on-site training of the assembly of the modules and
the training of the operators. The subsequent installations can be built from the income
derived from the output of the first several units. This will employ 12 to 20 people in
permanent jobs. That makes the ROI on all Units around three to five years.
A US$10M investment will purchase the Expanded PFAS Commercial Package covering
up to 30 to 32 full-size units complete and operational. This is a turnkey price and
includes all the on-site training of the assembly of the modules and the training of the
operators. The subsequent installation can be built from the income derived from the
output from the first ten or so units. This will employ 100 to 130 people in permanent
jobs. That makes the ROI on individual Units less than two years and creates ongoing
revenue streams from the sale and building of Units for other investors or organizations.

A US$50M investment usually covers several different territories/areas/cities under the
same investment in the Expanded PFAS Commercial Package and in some cases covering
an entire country. Each of these larger Expanded PFAS Commercial Package receives the
benefits of the single Expanded PFAS Commercial Package in having the training and
building of the first modules. This size investment will employ 600 to 1000 people in
permanent jobs. The ROI on individual Units is less than two years and a wide variety of
higher level position have been created to run a larger organization.

Appendix A: Portable Farms® Aquaponics Systems’ Yield Results
Two different methods were used to calculate expected yields and compute the ROI and profitability in the commercial size 1,000m2 (10,000 sq ft) PFAS Units.
The first method used in calculating production figures for lettuce, tomatoes, zucchini and basil
was derived from the actual production observed in the 6m x 9m (20’ x 30’) PFAS UNIT at the
Research Center in Escondido, California, USA, over a three-year period. The yields
approximated the aquaponics yields noted in reference literature and in the cases where the
yields were slightly higher (at the Research Center); figures were lowered to be similar to those
achieved in other systems.
The PFAS installation cited was the fourth production farm, and many of the initial design and
logistics problems had been worked out by then, so it represented the state of the art at the
time. PFAS LLC has continued to refine the systems, and the yields have improved slightly due
to more consistent production output.
The second set of figures were derived from University field trials from various Agricultural
Colleges in the United States for greenhouse production of ground grown plants. In each case,
we lowered our estimates to match their lower range of production.
The use of two sets of yield figures derived from two very different sources in publishing our
yields is very different from the normal practice of noting the range of yields and focusing on
higher figures from the best yielding situations. The figures used in the ROI computation are
based on observed yields over a broad range of growing conditions and in all cases the middle
to lower range was quoted and used to arrive at the stated amounts of product per Unit.

The additional initial capital investment and operating expense of increased electrical power for
the use of Grow Lights is offset by the increased variety and production that includes growing
and selling of blooming plants. The ROI of the installation remains approximately 3 to 5 years
even with additional capital costs and operating expenses for the use of Grow Lights.
For example: In planting Romaine lettuce we found that a spacing of 20cm to 23cm (8” to 9”)
apart as measured from center of the plant, as well as using offset rows, yielded the greatest
growth rate and the quickest harvest times. A second interstitial planting can also be done four
weeks from harvest if carefully executed to effectively increase overall yield a full 40%. We do
not include this type of enhancements to the yield figures. Skilled operators will use this and
other methods to enhance production output and profitability because the fish are producing
more than enough nutrients to support this higher density planting.
Mineral Rock Dust – Organic Additive for Micro and Macro Elements
The cultivation of blooming plants presents a dilemma
because these plants need more nutrients than the fish waste
can provide which provides ample nitrogen but lacks in
micronutrients such as calcium, iron, magnesium and
potassium. Greens grow exceptionally well using only the fish
waste, but blooming plants need more micronutrients to
support the blooming and fruit formation. The addition of a
very small amount of organic mineral rock dust is added to
the seed-starting medium, and an occasional one tablespoon
addition to the fish tank is all that is required. This means that
a 22kg (50lb) bag of the mineral rock dust will last more than a full year for an installation of
1,000m2 (10,000 sq ft) in full production of blooming plants. The mineral rock dust is very
inexpensive and can be stored indefinitely in the sealed bags.
Mineral rock dust does NOT contain nitrogen that is already being generously supplied by the fish waste from the fish in the fish tank(s) so the combination of the freshly produced nitrogen from the fish waste and the many macro and micro mineral elements in the mineral rock dust provides the perfect combination for growing healthy plants in aquaponics systems.
The mineral rock dust that we recommend is an amendment or addition to a system that is
safe and effective to use in all types of aquaponics systems (medium base or raft systems).
The pristine mineral product is certified organic (USDA in the state of California) and is 100%
natural. PFAS LLC has used and recommended mineral rock dust for four years and

experienced excellent yield results. These minerals are vital to growing both green plants
and blooming plants in every stage of growth: Seed planting, root development, plant
growth, plant health and plant blossoming. The use of this mineral rock dust produces
plants that are healthy during every stage of growth and development. This product is also
environmentally friendly and does not pollute nor does it ‘burn’ plants.
Colle Davis, Lead inventor Portable Farms® Aquaponics Systems standing in front of a Grow Table with tomatoes
growing behind him. Please note the trellises that allow vertical growing to maximize grow space.
Tomatoes present an interesting opportunity because of two factors: The first is that all
tomatoes must be staked or trellised (vertical growing) to maximize yield. This keeps the plants
upright and allows the utilization of the entire column of growing space from the Grow Table’s
surface to the area 2m (6 feet) or more above the Grow Tables. Trellising can be seen as a type
of natural vertical gardening. Trellising also makes harvesting much easier because the fruit is
more readily accessible. Pollination is also easier due to the open access to the blossoms.
Circulating fans are very effective in the pollination of most plants and reducing the humidity
and heat when the plants’ blossoms are opened up on trellises.
To successfully grow tomatoes and other blooming plants (peppers, cucumbers, beans, etc.)
year round requires the use of Grow Lights suspended above the Grow Tables in a climatically
adapted environment. The investment in the Grow Lights and electricity for the purpose of
growing blooming plants is offset by the increases in both variety and production.
One of the challenges with tomatoes is to determine how long to leave the plants in the gravel
before removing them and replanting in the same spot in the gravel. The recommended spacing
on tomatoes is 30cm (12 inches) and not to offset the rows for maximum outreach of the
plant’s growth. Our research discovered that the plants begin to produce tomatoes at 81 – 89

days (depending on conditions) but after approximately six to eight months of growing in the
gravel, the tomato plants develop such a large root ball (the size of a football) that they began
to impede the effective flow of water through the Grow Tables. This is especially true when a
Grow Table was planted with only tomatoes. This root ball’s large sized necessitates the
removal of the mature tomato plant after the sixth to the eighth month. The immature
tomatoes can be harvested before the plants are removed to add to the overall production. The
gravel in the area is then cleared of root fragments, and a new plant is immediately placed in
the same spot. This process is thoroughly and carefully covered in the Operations Manual©
provided with each installation.
The recommended spacing for basil is 18cm to 21cm (7 or 8 inches) between plants with offset
rows. This spacing allows for over 450 plants to occupy each 18.6m2 (200 sq ft) tray. This is
possible because the root system of basil is short and does not create a ‘large root ball’ under
the gravel. By harvesting four cuttings per plant on a monthly basis, the plants will continue to
produce over a five to six month period and will require only two plantings per year. For whole
plant basil the planting can be even closer together, 15cm to 18cm (6 to 7 inches) apart and five
plantings per year will be possible because the plants are pulled out for harvest instead of
clipped off. The harvesting and replanting into the same space is the normal practice to
maximize production.
The most surprising result of the research is that basil, touted as one of the most valuable of
the high-cash crops, was displaced by the shortest ROI crown by cucumbers. We computed the
cucumber numbers four times including the actual output from a current PFAS installation to
make sure we had not done some part of the calculation incorrectly. Our own results with
cucumbers and basil in the same Grow Tables at our Research Center in Puerto Vallarta, Jalisco,
Mexico, verified the University Agricultural Stations yields as being well within range of
expected aquaponics production.
Using the lowest yield with the shortest harvest season and three crops per space per year the
Return On Investment will be approximately 8 months [38kg (85 lbs.) x 52 weeks = 4,220 lbs
(1,900kg) of cucumbers per year per module] and priced at $2.25 per pound = US$9,945]. In
most cases, this production number will be much higher and will continue to rise as the
operators become more skilled and the system matures.

The above numbers are based on the lowest expected yields from greenhouse grown crops, use
the shortest possible harvest time plus the longest time from transplant to finish harvest. In
other words, the lowest possible output from the Module for this crop is shown. The actual
output from each Module can and probably will be from two to four times as high resulting in a
much shorter ROI.
With more and more installations being built in different locations, screened roof vents, the use
of movable shade cloth, carefully-followed harvesting schedules, and noting local weather
conditions, the production yields will more accurately be reflected for each type of climate and
the operator’s level of experience. Every installation will function and produce differently, and
yet the yields will meet or exceed the stated output.
The figures noted in the ROI do NOT reflect land lease/acquisition costs. They do however
include labor, seeds, planting medium, fish, water, the use of grow lights in winter months, and
electricity. By initially marketing to the high-end restaurants, markets, and resort hotels, the
ROI will remain high as the increased produce begins to be directed at the lower end markets
because of the volume being produced. Additionally, the yields will increase approximately
20% the second year as the system ‘cures’ and becomes more stable. Third and subsequent
years can see increases due to operator efficiencies.
