Are you tired of paying exorbitant prices for poor quality produce? Are
you concerned about the heavy use of pesticides and fungicides in
commercial food production, not to mention the frequent recalls due to
bacterial contamination, but just can't afford to shell out the extra money for
organic?On the other hand, are you a busy person with a life to live and no time to
spend 20 hours a week growing a garden? Or are you unable (or unwilling!)
to tackle the back-breaking work of tilling, hoeing, fertilizing, weeding,
watering, planting, and harvesting?
Well now there is a solution for you! For the price of two or three trips to
the grocery store you can have your own hydroponic lettuce and herb garden,
producing many times the volume of lettuce, greens and herbs your family
can use - regardless of the size of your family! Not only that, but with theknowledge contained in our video you can turn your family hydroponic
garden into an extremely simple and profitable home-based business! It is not
uncommon to see lettuce, which is ridiculously easy to grow with this system,
selling for four to six dollars a pound and more - and herbs at $20-50 dollars a
pound and up!
The pesticide and herbicide free market is expanding exponentially in
these last few years as we become conscious of the growing dangers of
pesticides and herbicides to our health. Now is the perfect time to enter themarket yourself and carve out a niche business selling lettuce to your
neighbors, your friends, local restaurants, hospitals, delis, supermarkets and
any place that wants high-quality locally grown lettuce!
And the greatest thing is your lucrative home-based business can be up
and running and turning a profit in under six weeks! And the investment is
about as small as you can imagine for such a venture! But even if you're not
interested in becoming a lettuce tycoon, this could make an excellent project
for school or a great way for a non-profit group to help the needy. The sky'sthe limit on this project, you can build the lettuce bed as large as you need and
expand it even bigger when your market grows! And whatever else happens,
it's almost impossible NOT to grow ten times more than your own family can
use!
OVERVIEW
This is a constant flow fully hydroponic system. Hydroponic means that
all of the nutrients the plant needs comes directly from water continuously
flowing past its roots. With our system we use 2" PVC pipes with 1.5" holesdrilled every six inches along the top side. These pipes are placed at a slight
incline, and at the upper end of the incline, 1/8" poly tubes feed a small

amount of water into each one. This water is caught in the drain reservoir at
the lower end and pumped back to the top to begin the cycle again.
Meanwhile, we plant our lettuce seeds in a tray full of small inert cubes to
germinate and we leave them there until they are approximately an inch tall.
When they are tall enough, they are placed into the 1.5" holes in the 2" pipes.As the water in the pipes flows past the inert cubes containing the seedlings,
the absorbent material of the cube holds the water and the young plant is able
to use only the amount it needs without getting waterlogged.
Water-soluble fertilizer is placed into the reservoir as needed and thenutrients the plant needs for growth and vibrant health are absorbed from the
water flowing past the roots of the plant. As the seedlings grow they willspread out, completely filling the space between the holes and covering the
pipes with a blanket of green and red leaves.As soon as that happens, you will be ready to harvest your first full crop.
To pick lettuce, remove only the largest outside leaves. As you pick the
outside leaves the inside leaves will grow faster to replace them, to be picked
in their turn. Using this "cut and come again" method of growing, you can
have a full picking - depending on the size of your lettuce bed, yielding
perhaps dozens of pounds of top quality lettuce - every other day!
Depending on the variety of lettuce you choose, your day length and the
air temperature, your lettuce may stay in full production for several weeks toseveral months before "bolting" and going to seed. When that happens the
lettuce will begin to taste bitter and it is time to pull it, compost it and replace
those plants with new seedlings. Where I live in Texas, we can grow lettuce
year round - although a greenhouse is required during the coldest months of
winter with only moderate amounts of heat. Most lettuce will tolerate
(although not thrive) in temperatures almost to freezing and up to 100
degrees Fahrenheit, making it a very forgiving crop. In a more northerly
climate this bed could stay in production from the last frost to the first one,producing perhaps a thousand or more pounds of lettuce! Of course, this
system can also be used to grow many herbs; mint thrives, as do oregano,
basil, thyme and most other herbs.
And you will be amazed at the amount you can pick; with only 8 pipes 40'
long it was common for us to pick over 50 pounds of lettuce every other day!
And because of this unique soil-less growing system the lettuce comes off of
the pipes clean without sand or dirt of any kind, so no laborious washing is
needed! We found that few pests bothered our lettuce bed, which makes it not
only undesirable, but entirely unnecessary to use noxious chemicals!

CHAPTER 1: GETTING STARTED
Let me preface this by saying that these are only loose guidelines; you
can substitute many of the materials used if you have others on hand, this is
just to give you an idea of the items involved. To build one small lettuce bed,
with seven pipes 10' long you will need the following materials:1 - plastic 55 gallon drum
7-10 ' lengths of 2" PVC pipe (plus 10' to be cut for shorter connections)
16 - 2" plastic pipe brackets (such as those used to hold electrical conduit)
3 - sawhorses
1 - small fountain pump, 150 GPH@1' lift minimum. 1 -
20' length of 1/8" black poly irrigation hose 1 - 20'
length of 5/8" black poly solid irrigation tubing
1- barbed plastic "T" for the poly pipe2- barbed cap inserts for poly pipe6 - hose clamps to hold the poly to the fittings
1-3' piece of 4" pipe
1-10 ' length of septic drain sock
7-2" PVC "street" "L"s
4-2 " PVC "L"s
6- 2" PVC "T"s7- 2" PVC caps1 medium can each PVC glue and PVC cleaner Nylon

Notes on the materials needed:
Find a barrel that was used to store food-grade materials, not chemicals.
Find one with solid bungs on the end that will seal tightly to hold in the water
because you will be installing it on its side. Clean it thoroughly with bleach
and rinse very well before using it (this can be done after cutting holes in it asdescribed in Chapter 2 to make it easier to clean if necessary).
When selecting pipes try to select pipes that were stored indoors or in theshade. Sunlight is harmful to PVC pipes and makes them brittle, which willmake it more difficult to work with it and shorten its life. We recommendbuilding your own sawhorses because you can control the height exactly. Inorder to drain properly, the lettuce bed needs a drop of 2-3" over 10'. So
unless you are building on ground with a natural slope one sawhorse must be
2", and one 1" taller than the shortest one.Kits are readily available to build your own sawhorses which makes it
very easy to make one end taller than the other, but if you use existing
sawhorses simply block one end to make it stand taller. The height should
slope from approximately 38" to 36" tall if the person who will spend the
most time picking is of average height. Otherwise adjust the height
accordingly. The lowest sawhorse must be specially made or cut; it must
slope from 36" on one side to 34.5" on the other. This will make the pipes all
drain to one side. The other sawhorses will be level on top. For 7 pipes to fiton 8" centers, the sawhorses must be about 52" wide.
Many fountain pumps are available and nearly any one will do; the more
pipes you run off of a single pump the larger it must be, but in general for less
than 7 pipes not less than a 150 GPH@1' lift pump is required to provide
enough flow. 1' lift doesn't mean it won't pump higher, just that that is how it
was rated. Larger pumps are acceptable, but if they have too much flow, the
extra will need diverted using some sort of a bypass system. Make certain the
pump is designed to be fully immersed in water.Septic drain sock is used in septic systems to go over the drain pipe to
prevent sand from flowing into the slits in leach beds. It looks something like

pantyhose. It is very inexpensive and you will use it to filter the water
returning to the barrel. The PVC caps can be either the regular heavy caps or
the cheaper "knockout" caps.
The tubing poker is designed to poke holes in the side of the soft 5/8"
tubing so that the 1/8" tubing can be pushed into it. It should be available inthe irrigation department of your home improvement store. While you are
there find a way to adapt 5/8" poly tubing to the outgoing side of the pump
you intend to use - depending on the model, it may be very easy or a bit tricky.
There are several different Ways of doing it and the store should be able to
help you select one.
The 2" brackets should be gray plastic, other materials will rust in the
presence of the fertilizer and water. They will probably be in the electrical
department. These will be used to hold your pipes in place.More details on fertilizer will be given in Chapter 6: Fertilizer. Lettuce
seeds and suppliers are also given in their own chapter - Chapter 10:
Suppliers. Oasis cubes can be also purchased from many nurseries or from
suppliers listed in Chapter 9: Lettuce As A Business.
CHAPTER 2: STARTING TO BUILD
The first thing you must do is find a stable, fairly level or evenly slopingsurface that is well drained and accessible to water and electricity. If your
surface slopes adjust the height of your sawhorses to compensate so that youare left with 2-3" of drop over 10'. You can determine your drop by taking along, straight 2x4 and placing it where your pipes will be setting. Place a level
on it and raise it until the bubble centers - then have someone measure fromthe bottom of the 2x4 to the top of the lower sawhorse. This is your drop.From now on these instructions will assume you are building on a reasonablylevel surface.
Set your three sawhorses 5' apart, make sure they are stable and setting
firmly on the ground, and make sure that they line up and the center onedoesn't sag or hump (either of which will make the water not drain correctly).
Next take the barrel and lay it on its side, with the manufactured seam
side up to give you a straight line. Take your 4" pipe and put the end on the
barrel centered approximately 6" from the upper end. Mark around the
outside of it with a magic marker, drill a hole inside that mark with the 1/2"
drill bit and using the jigsaw cut the circle out and discard. The 4" pipe should
fit snugly inside the hole and down into the barrel, sticking out about 3". Cut
off any excess and smooth the rough edges.Remove the 4" pipe from the barrel and drill a BUNCH of holes in the 4"
pipe with the 1/2" drill bit. It should look roughly like a honeycomb when
7/30/2019 Grow Your Own Hydroponic Lettuce
7/15

you are done. You are making a rough "screen" out of the pipe to hold the
drain sock "filter" you are going to make. Every hole you make gives the sock
more drain power. When the pipe is thoroughly perforated clean all the burrs
off of the holes you drilled using a knife, file, or heavy sandpaper. Tie a knot
in the end of the drain sock and set it into the 4" pipe, and pull it all the way tothe end of the pipe with your other hand. Cut it about 3' long and fold over the
top of the 4" pipe. Using nylon zip ties or a hose clamp, tie it snugly in place
around the top of the pipe. Then lay the whole thing out of the way for now.
Set the barrel on its side so that the 4" hole for the filter is on the top.
Mark an 8" hole centered 12" from the lower end of the barrel in line with the
6" hole so that both will be on top when it is installed. Cut it out just like the
other hole and smooth the edges with a sharp knife. This is where you will
lower the pump into the barrel and add your fertilizer. When finished, setaside, but do not discard the cutout. Set your 2" pipes, one at a time, on a
stable surface or workbench and with a pencil or chalk-line put a mark all the
way along the top side of them. If the words marked on all PVC pipe are lined
up straight you can also use those for a mark. Mark all 7 pipes this way. Then
starting at the end, put a mark every 6" along it crossing the first mark. Mark
4 pipes this way.
On the other three pipes put the first mark 9" from the end, then mark
every 6" as before. This will offset the holes so each plant has more space.Then take the 1.5" hole saw and drill a hole at every mark. These are the holes
your lettuce will set in. Drill every pipe and clean the burrs from the holes
with a sharp knife (carefully!).
Glue a 2" "street elbow" (an elbow with one male and one female end)
onto the end you DIDN'T mark from on all 7 pipes (this will be the lower
end). Be careful to orient them as you glue them so that when the elbow is
pointing straight down, the holes you drilled are along the TOP side! Glue the
caps onto the upper end (the end you DID measure from) of the lettuce pipes.As I've said, pipe tends to get brittle in the sunlight because of UV
deterioration. These pipes will mostly be shaded by the lettuce, but you may
wish to paint them a reflective color to help block sunlight and extend their
life, or you may wish to coat them with aluminum foil tape. This last has the
added benefit of annoying bugs and helping deter algae growth by blocking
light from the pipes. I mention it as an option only, for it is not necessary to
get a lot of use out of your lettuce pipes.
Now set two of the T's you will use, lined up as if they were to be glued to
the pipes, and measure 8" from center to center. Then measure from the stop
on the inside of one, to the stop on the inside of the other, to see the exact
length that the pipe must be to glue these together at exactly 8" apart. It
7/30/2019 Grow Your Own Hydroponic Lettuce
8/15

should be about 5". Cut 7 pieces of 2" PVC (from your extra piece) to that
length.
On a flat, stable surface, lay out 6 T's in line, with the pieces you just cut
beside them. Glue them all together in a row. It is CRITICAL that these are
glued together straight - with all the open ends of the T's (if you imagine theletter T - the bottom end) pointing in the same direction. They cannot be
twisted more than a fraction of an inch or they will not glue into the pipes you
are about to make. You can align them on a table or by sight. Then glue the
last 5" pieces of pipe into each end of the T's. Glue a 2" L into one end,
aligned with all the other T's. This is your manifold drain. If you are confused
by all this don't worry, it is a very simple task, it just looks hard on paper. The
accompanying DVD will make this process clear.
Arrange all seven lettuce pipes on the tops of the sawhorses in the orderin which they are to set (so that the three offset pipes set between the fourregular pipes). The short pieces you glued onto the elbows should dangledown. Have a carpenter's square handy, if available. Then grab the outsidepipe on the HIGH side of the LOW sawhorse and glue to the elbow end ofyour manifold. Using your square try to get it as close as possible to a right
angle to the pipe.
Then glue the first T into the next pipe, making sure the pipe is parallel
with the first you glued. If it is parallel with the other, and the other is square,then both will be square. Continue for all the other pipes. When done, all the
lettuce pipes should be approximately 8" apart, and the last "T" should have a
3" or so piece of 2" pipe sticking out the end of it.
Onto that 3" piece, glue an elbow to point horizontally away from the lettuce
runs, and slightly downhill. Cut a 3" piece of 2" pipe and glue it into the open
end. Now take your barrel which you had set aside earlier and place it
between the legs on the sawhorses, with the drain end (the 4" pipe) on the
barrel closest to the drain end (the elbow you just glued in) on the lettuce
pipes.
Temporarily block it in place. Center the pipes on the lower sawhorse.
Glue the next elbow to the last piece of pipe, pointing towards the barrel at a
significant slope to allow for good drainage; about 1" per foot is good. Glue a
piece of 2" pipe into that "L" that ends just short of the center of the 4" hole
on the barrel. Glue the last "L" into that pipe, pointing straight down into the
barrel. Cut a piece of pipe long enough to reach from the last "L" down into
the barrel to avoid too much splashing. Stick it into the end of the pipe, but
DON'T glue it!
Block the barrel so that it cannot roll at all using either dirt, blocks, wood,
or whatever material is available. Attach the two outside pipes with the pipe

brackets. On the upper end line up the pipes so they are the same distance
apart as the lower end and attach each pipe with the brackets. Unless they are
warped, the center pipes will not need to be attached to the sawhorse. Now is
a good time to stop and take stock; your project should be starting to come
into focus and look like a lettuce bed. You have the drains all connected andthe barrel made. The only thing left is to set up the water supply and the filter.
CHAPTER 3: WATER SUPPLY
Take the poly tubing and cut 2 pieces about 30" long (if your sawhorses
are 52"). Set aside. Drill a hole through the upper two sawhorses large
enough to allow the 5/8" poly tubing to pass through. The holes should be
drilled directly under one of the pipes. Starting at the lower end, thread the
poly tubing under the first sawhorse and through the second two. Attach the
tubing to the pipe in at least two places between each sawhorse pipe usingnylon pull ties. Make sure that the ties girdle the pipe between the lettuce
holes and don't tighten them too tight - if the poly looks kinked, it won't carry
water! Just snug it enough to keep it from sagging.
When you get to the upper end pull the poly about 1" past the end of the
upper sawhorse. Push the "T" into it and attach the hose clamps to hold it in
place. Attach the poly pipes into the open sides of the elbow and run them
across the pipes on the underneath to the outer edge. Cut them about 1" past
the last pipe and attach the plugs like you did the elbow. Use 1/2" or 3/4"mounting brackets to attach the tubing to the sawhorse.
Cut 14 pieces approximately 1' long of 1/8" poly tubing, making each cut
at a diagonal angle.Then drill 2 holes with the 1/8" bit into every pipe at the
top of the bell. Drill them at a 45 degree angle leaning into the pipe, so that
they will "aim" the water down into the pipe. Using the tubing poker poke
two holes per pipe into the poly tubing in the exposed area between each pipe.
Grab the 5/8" poly firmly in one hand and with the other force a length of
1/8" poly into it. Loop the 1/8" around so that it makes a smooth loop aroundand into one of the holes in the lettuce pipe. Repeat for all 14 pieces. Make
sure each tube is securely into the 5/8" poly and into the lettuce pipes. Cut the
other end of the 5/8" poly (the end by the barrel) long enough to reach to the
bottom of the barrel. Attach it to your pump using whatever adapters are
necessary, if any. Now retrieve the cut-out from the barrel that you saved
earlier. Cut a 1" hole out of one edge to fit around your poly and pump cord.
Take two strips of treated lumber and screw to the edge of the hole, on the
inside of the barrel, one on each side. The cutout you saved should just fit into
the hole around the tubing and cord and seal off the barrel from mice, spiders,
debris, and keep your reservoir clean. As an option, you may wish to cover
the barrel in foil-faced bubble insulation to reflect light and heat from the
7/30/2019 Grow Your Own Hydroponic Lettuce
10/15
10
barrel. Depending on your location and climate, the water in the barrel may
get unpleasantly hot in the sunshine which can hurt your lettuce production. Ifyou intend to do this, do it now.
Next fill the barrel 3/4 full with water and plug in the pump to test all of
your connections. PLUG THE PUMP INTO A GFCI GROUNDEDOUTLET! Otherwise there is a risk of severe shock if the pumpmalfunctions! Then make sure there are no leaks on any of the joints ordrains. It's a good idea to let it run all night to make sure all particles are out ofthe pipes and into the filter, and that your drains are not going to clog up. Andthat's it! Your lettuce bed is finished!
CHAPTER 4: GROWING FROM SEED
In order to support the young lettuce plants in the pipes it is necessary to
place them in a solid medium. For this we like to use Oasis cubes. This is anextremely light but incredibly absorbent substance and is available from
many greenhouse and plant growers around the country (see Chapter 10:
Suppliers). Oasis cubes come in a sheet about 12" by 24" by 1" thick. It is
perforated so that the individual 1" cubes can be broken off when the plants
get large enough to separate, and it has a small hole in the center of each cube.The best way to start lettuce and other herbs is to take an old tray and put
a sheet of Oasis cubes on it. Put your seeds in a small saucer and set it on the
cubes and using tweezers put one seed in each hole. Plant about 25% morethan you expect to need (for 7 tubes with 19 holes each you will have 133holes to grow in) since you cannot count on every seed germinating.
When all seeds are in place set the tray in a warm, well-lit spot. Gently
pour water along the side of the tray. Do not pour water on top of the Oasis
because you will wash the seeds out! It will absorb 40 times its weight in
water, so expect it to take a lot. Add it until water stands in the bottom of the
tray and is no longer absorbed, making sure the cubes are wet all the way to
the seeds. The top will probably not get wet, but make sure that the holes
where the seeds set are damp. Give it time to wick up and come back every
half hour or so and add more water.
Check back on your cubes to make sure your cubes are saturated with
water twice a day. No fertilizer is needed yet, but as soon as the seeds sprout
and peek above the tops of the Oasis cubes, fertilizer will need to be added.
Then add fertilizer to the 55 gallon drum reservoir as described in Chapter 6:
Fertilizer, and pull out a cup of fertilized water from the barrel and add to a
cup of plain water. Stir and pour the mixture over the seedlings.
We do this because it is important to dilute the fertilizer as the tenderplants don't need much fertilizer yet and too much would shock them. Allwater that you add to the seedling tray from this point on will be 50/50
7/30/2019 Grow Your Own Hydroponic Lettuce
11/15
11
fertilized water and regular water. It will usually take, depending ontemperature, light, and seeds, between one to three weeks from planting until
you have small plants ready to move into the pipes.
When seeds germinate they first have "baby leaves" which are really just
what grew as the sides of the seed. Then those separate and the first trueleaves come out. Sometime between when the first and second set of true
leaves come out on the majority of the seeds it is time to separate them and
move them to their new home in the pipes. They will probably be about 1"
tall at this point.Break each plant off into its own cube. Carry the tray to the lettuce pipes and
set it aside. Turn on the pump. Once the water starts flowing take one fully
wet emptycube (one whose seed didn't germinate for instance) and set it into
one of the holes in the center pipe. Watch it and see if the water flow washes itaway. If it does, then you either have too powerful a pump - in which case,
you need to open your bypass or build one - or too much slope, in which case
you need to reduce it and try again. Keep trying until the flow doesn't wash
the cube away. Then try another tube (one towards the center of the bed,
where the pressure will be strongest) and make sure the water flow doesn't
wash it away there either.
If all is well and the water won't wash your cubes away, start setting the
real lettuce cubes in place, upright, one in each hole. Put a toothpick into eachoasis cube to make sure they stay upright and don't fall down into the pipe.
After doing one pipe, go back to the top and make sure that none of them are
sliding or slipping downhill. It is better to have less flow than too much!
Continue until all pipes are filled. Next it's time to fertilize the barrel.
Incidentally the planting in the Oasis cubes can be done as soon as you get the
seeds, while you are building the lettuce beds themselves, to give you a
head-start when your lettuce bed is ready.
CHAPTER 5: PLANTING STORE-BOUGHT SEEDLINGSIf you're in a hurry, it is also possible to buy young lettuce plants from a
local nursery that are already well on their way to maturity. It is possible to
cut up to a month off of the time it takes to harvest your lettuce this way. To
use plants like this, start by gently removing the plants and their soil from the
tray and (if necessary) gently breaking up the soil to loosen it. Lower it into a
bucket of clean water and swish back and forth several times, being careful
not to break off the stems of the young plants. Don't worry if a few broken
roots fall away, more will soon grow to replace them.
When 90% or more of the dirt has been washed away, slowly lower theminto the lettuce pipes, and guide the roots to flow downstream as you lower it.Set it in place so that it is facing up, and repeat with the next plant. A few of

the outside leaves may wilt over the next few days, but the inside leavesshould come up vibrant and green to replace them. Fertilize the barrel
immediately after placing the plants in the tubes, as described in the nextchapter.
CHAPTER 6: FERTILIZERThe concept of hydroponic growing is that ALL food must enter the plant
through the water, or through the leaves. Unlike soil growing where a hardy
plant can draw much "food" out of even poor soil, if the nutrients are not in
the water they cannotbe in the plant!
We use a variety of different fertilizers in our mix. You can experiment
with this on your own but we recommend that you stay close to our blend for
your first few batches at least. To make the first batch fertilizer, take:
4 ounces Lettuce Formula (8-15-36) (Chapter 10: Suppliers)
4 ounces Calcium Nitrate
2.5 ounces Magnesium Sulfate (Also called Epsom Salts)
All measurements are by weight. Mix together thoroughly and add to thebarrel of fresh water, stirring very well. The mixture will immediately startrecycling through the tubes and often you can often see a visible difference inthe plants over a few hours after fertilizing. Each plant in each environment
will feed differently so you will have to monitor them yourself to know whenthey need more fertilizer, but usually this will last for several weeks.
When you see your plants starting to look peaked, long and lanky, not
very vibrant, a pale yellow color, or see strange spots and odd colors in the
leaves it means they are hungry for something. Which means it's time to add
more fertilizer.
This fertilizer formula works very well for all types of lettuce and mostherbs. However each environment and plant is different so you may wish to
modify it or add supplements to it from time to time. Unfortunately due to thelarge amount of possibilities involved, we can't offer any more detailedadvice than we already have here - trial and error will teach you the exactrequirements of your environment.
CHAPTER 7: MAINTAINING YOUR LETTUCE BED
One of the greatest things about this gardening system is that it is almost
entirely maintenance free. There are no weeds, few bugs, and all the work is
at waist-level so there is never any bending or kneeling to work on your
garden.Your lettuce beds should be visually checked on a daily basis if possible.
You will need to change the filter from time to time and replace it with
7/30/2019 Grow Your Own Hydroponic Lettuce
13/15
13
another drain sock. You will need to make sure that nothing slipped past the
filter and clogged up the 1/8" tubing lines, otherwise that pipe might not be
getting enough water. That is why you must use two lines for each pipe, to
double up and give yourself a safety net. You will also need to periodically
add fertilizer as it is used by the plants and water as it evaporates. Also it ishelpful, particularly in hot weather, to aerate the reservoir barrel by putting
an aquarium pump with a stone bubbler on the end into the barrel. They are
available at pet stores and help oxygenate and cool the water.The only critical thing is that this is a CONSTANT flow lettuce bed.
That means that the water must flow CONSTANTLY! The Oasis cubes will
hold some water, and the lettuce plants themselves can survive for a while
without flowing water, but not too long! The exact time depends on the age of
the plants, the humidity, and the temperature. On a cool night it might nothurt them at all, but a few hours in a hot, dry day will make your lettuce
crispy. In a bad way. What this means is that if you live in an area prone to
frequent power outages it would be wise to have a twelve-volt backup pump
that can run off of a battery for a while, or better still a generator that can run
the pump in case of a power outage. And if your pump should fail it would be
a good idea to have a backup pump on hand. That said, there is very little risk
if you have a backup available or are in a stable power grid. And excepting
those things, there is virtually no maintenance involved in this system! Just
plant it and pick it!
CHAPTER 8: PICKING
There are two ways of picking lettuce. You can either wait for it to form a
head and cut the entire plant off, or you can pick some leaves off of the plant
on a regular basis and let them grow back. Pound for pound you will get
much more lettuce by pulling off a few leaves at a time. Heads look nicer but
they take longer to make and only produce a limited amount per hole.
Because of this we recommend the "cut and come again" method. For
this, you will wait until the plants measure about 5" across to take your first
picking. The leaves should be at least 1" by 3" before you pick them, and pick
only the outermost leaves. At first just pull off a leaf at a time when the plants
are smaller with weaker stems, and only one or two leaves per plant.
As the plants grow and become more sturdy they will produce faster,
produce many more and much larger leaves. When they get to that stage, hold
your right hand like you are making a "C" with the thumb and fingers. Make
the "hole" of the "C" large enough to fit around the core leaves of the target
plant. Lower your hand straight down over the core, close the "C" and dragyour fingers back around to the side of the plant towards your palm. When
you get all the outside leaves dragged together into a nice bundle, with the

core and stem untouched, give a gentle twist; the leaves should break off very
crisply then drop them into a clean trash bag or a large container. It is very
simple and once you get the hang of it you can pick the entire bed in just a few
minutes.
CHAPTER 9: LETTUCE AS A BUSINESSWe started growing lettuce first for ourselves, but found it produced so
well that we had hundreds of pounds a week to unload. There is a vast market
opening up now for locally grown produce and good quality lettuce brings a
very high price at the supermarket. You can grow expensive specialty lettuces
like Endive and Arugula as easily as you can grow Romaine. Plus, with the
"cut and come again" method, you can have a pre-mixed batch of specialty
lettuce for salad right off of your tubes.
You will be amazed by how much a lettuce bed in full production canproduce - and it only takes about 30 days for most lettuces to reach production
age from seed! You will have to check health department and growing and
marketing regulations in your own state and town but in my area they do not
require you to have a license to grow and sell lettuce AS LONG as it is not
torn into a salad. It being torn would make it a prepared food product, which
requires a health department license and special kitchens and other things like
that.
There is room for both Retail and Wholesale ends of a business to bebuilt; retail has the advantage, as always, of more markup, but wholesale has
the advantage of less packaging hassle and more volume. Also a wider target
audience, since you can approach schools, hospitals, colleges, restaurants,
cafeterias, and any place that has a market for high quality, fresh, locally
grown lettuce grown without pesticides and herbicides. And our lettuce keeps
much better than lettuce bought in the store - when stored in gallon Ziploc
bags in the refrigerator, we've had lettuce stay crisp and fresh for as long as a
month! Healthy foods always keep better.
And your new business doesn't have to stop at lettuce; fresh, intenselyflavorful herbs are extremely expensive and in most cases as easy to grow aslettuce. Use your imagination. Most herbs can be started by putting a cutting
(a broken stem with a leaf, for instance) into an oasis cube and setting it intothe lettuce run.
Lettuce beds are easy to maintain, the lettuce is easy to process and bag,
and the beds are easy and affordable to make. Doing it as a business is
obviously not for everyone, but for an entrepreneur looking for a new
direction it might be just what it takes to make him a Lettuce Magnate, orjust bring in a little income on the side. And if nothing else, even a small bed

should allow you to grow more than you can possibly use and have plenty left
over to give to a good cause.CHAPTER 10: SUPPLIERS
While many stores can supply seeds, often they are old or of poor quality.
A source for good quality and exotic seeds of lettuce and other herbs andplants is Territorial Seeds www.TerritorialSeed.com. Fertilizers can be
purchased fromwww.Hydro-Gardens.comwhich also offers Oasis cubes and
many other specialized hydroponic growing supplies. Unfortunately their
website is a bit difficult to navigate currently. A direct link to a product index
is www.hydro-gardens.com/director.htm which simplifies things somewhat.
These supplies may be available locally but we list these here as options.
CHAPTER 11: FREQUENTLY ASKED QUESTIONS
What can't I grow?Technically you can grow anything, but some types of plants require their
own fertilizer; spinach for example, doesn't grow well in this fertilizer mix.
Neither does cilantro. Other types of plants grow too large and won't fit in thepipes once they reach maturity (tomatoes, squash, etc) and also don't growwell in this fertilizer mix. However, there are ways of adapting this system togrow tomatoes, watermelons, and other vegetables, which we are currentlydeveloping into an instructional video and brochure like this one, so checkback at our website in the future for more gardening ideas.
Can I make the pipes longer?
Yes! I have had lettuce pipes that were 40 feet long, and they can be aslong as you like if you just keep a downward slope to them. And the best partis that you won't need a bigger pump - the water just naturally flowsdownhill!
