Intro to 3n1 Aquaponics SIG

Colorful cherry tomatoes announce an important focus of this course, “Hands-on Aquaponics with Distance Learning (HOADL).” As important as production of colorful, tasty produce is, course structure and delivery can actually be as important.

The fact that these red peppers were grown in water instead of soil is amazing in itself. But, what is even more amazing is learning growing techniques on-line, and then self-assessing when sufficient skills have been gained for managing processes AND growing produce!

Certainly, there are materials to read: The four course volumes tell and show you the adverbs of an OJT style course. But, the focus is on what you do with your hands during learning that really counts! Take a moment and look at the major parts of our 3n1 Aquaponics Soilless Indoor Gardening (SIG) System. This short program explains how you will be using this system configuration to learn fundamentals of Aquaponics!

The Plant Bin sits on the top of this 22” L x 13” W x 22” H wire cart, and the Nutrient Bin sits below it. The dimensions of a 20-gallon (aquaculture) aquarium or plastic latch tote will vary by manufacturer. Pick your own configuration for a 20-gallon tank and stand – the containers can sit next to each other enabling you to use a table. A wire cart as shown, however, makes the part-two system easier to operate and maintain.

Illumination for our earlier DWC Hydroponics SIG was a High Pressure Sodium (HPS) - bulb and luminaire. The luminaire was suspended on a chain from the ceiling, making it easy to raise or lower the lamp over the plants. The HPS bulb was rated at 150 W, cast a strong yellow light, and generated heat that was controlled in the summer with air conditioning. A water chilling system as shown in Aquaculture subsystem components could also be used to chill the solution. A fan prevents scorching.

LED flood lamps are brighter and cheaper than just two years ago. The two-LED light installation shown here is a simple rail-mounted plastic housing and socket combo that hangs by chain above the SIG. The two15 W rated LED bulbs wired in parallel together generate an equivalent of 180 W of daylight. With better results than the HPS, the LED combo cost half of what the HPS cost to build, and one-sixth the cost to operate.

Plant Bin: Air line (1) with Check Valve (2) fed through the (3) Wide Lip Bucket Basket (9.75-Inch) and attached to (4) a 4-inch round air stone bubbler. Air that is generated ensures that roots receive sufficient oxygen during ebb and flow.

The airline (1) attached to the bubbler is routed through clay beads (2) filling the bucket basket. The white fitting and rubber grommet (3) secures the spigot. Rubber grommets (4) secure the plastic sight glass fittings protruding through the bucket wall. These components, the sight glass and spigot make it possible to set the interval timings supporting ebb and flow .

3n1 Aquaponics SIG System Plant Bin Parts: (1) Nutrient Return Spigot (2) Sight Glass (plastic tube), (3) Sight Glass Elbow Fittings. These components are key in identifying the ebb and flow settings, and are important in closed cover maintenance to prevent having to remove the net basket during the grow periods.

In an unmodified hydroponics DWC system, roots are submerged all of the time. But by setting Ebb and Flow intervals on a timer, the plant bin can be completely filled and emptied multiple times in a 24-hour period. First, start a submersible pump to fill the DWC, and at the end of the interval stop it to drain the DWC completely to let the roots breathe. The fat tube (1) supplies solution, and the spigot (2) at the bottom drains it.

A. Assume solution is drained from the 3n1 Aquaponics SIG System Plant Bin (1). B. Close spigot (2), and simultaneously start submersible pump (3) and timer watch (4). C. Turn off submersible pump when sight glass (5) filled; note “Fill” time. D. Simultaneously, restart stopwatch (4) and open the spigot (2). E. Stop stopwatch (4) and Note “drain” time - how long solution took to drop to the bottom

of the sight glass (5). F. Calculate ebb and fill interval as the difference between the “Fill” and “Drain”

measurements. G. Set the ebb and fill intervals on interval timer (6) for a 24-hour period.

Just as the plant bin air pump creates air bubbles through the round air stone, the nutrient bin air pump (1) fitted with Check Valves (2) safely keeps the aquarium well oxygenated through long air stones (3). The submersible pump (4) pushes solution up to the plant bin when turned on by the interval timer (5). The switch (6) manually switches on the aquarium light. Not shown here are the powered filter, heater and thermometer.

This close-up of two check valves and air pump emphasizes the importance of oxygenation in the aquaculture phase of the 3n1. Air bubble generation not only ensures that fish receive enough oxygen but that the waste conversion process of nitrification has sufficient oxygen to convert ammonia into nitrates. Bubble generation also helps to mix the solution. Check valves ensure that accidental reverse solution flow does not short out the pump.

Filtration and nitrification processes using Nitrobacter take place in the powered aquarium filter. The biological filter (1) is shown here in the cartridge holster (2). An overloaded filter emits a strong sewage odor and needs cleaning or replacement. Denitrification is the third biochemical process that completes the fish waste-to-plant food cycle. Denitrification occurs in the plant bin where nitrates are collected in the clay beads and washed into the plant roots.

5.14

The rate and amount of denitrification is partially dependent on the plants. The quality of seeds used in the germination process initially determines the health and size of plants. Once leaves begin to push through seed covers, transfer germinated seeds to a wettened paper towel and slide them into a Ziploc bag. Once the Ziploc is closed lay it flat to enable the seedlings to grow upward as shown.

If the Ziploc bag is hung vertically, roots grow downward and in parallel. Each seedling can be carefully separated and laid onto an open fiberglass plug so the root is straight.

Several short plants may be raised as shown. The seedlings were planted in split fiber grow plugs, so that most of each seedling’s stem was below the top surface of a grow plug with the part of the root hanging out. In this example, the foliage of one pepper plant would have been sufficient since the mature plants crowded each other reducing available illumination, water and food to each plant.

Shown here are hydroponic round DWC and rectangular tote container configurations in which plant roots are grown entirely submerged in a chemical nutrient solution. The bottled solutions were diluted into a chemical cocktail that was then vigorously oxygenated in the grow bin. The 3n1 Aquaponics SIG configuration was inspired by the poor results of the hydroponic DWC growing configuration.

Lack of adequate illumination was another problem; causing tomato vines to be spindly and fruit small. As mentioned, the chemically-based DWC configuration preceded the two-part configuration of the 3n1 Aquaponics SIG. Comparing results of the two types of configurations, natural nutrients resulting from the fish-plant symbiosis in the 3n1 aquaculture produced better, tastier fruit than with chemical cocktails in the DWC.

Once the fish in this shot were transferred from the aquarium to a 14-gallon plastic bin, they each grew to a length of 10 inches. Aquarium plants were first added as a source of food, but instead added algae that became an unwanted contaminant instead of an anticipated beneficial addition. Keep the aqua-culture environment free of algae-producing greens, and free of aquarium stones that harbor decomposing food and waste.

This is the root mass from the DWC that combined plants and chemical nutrients in one container. Healthy roots are white like those shown resting on the bin side just above the brown root mass floating in the dark solution. Stray light contributed to some browning of the roots along with unfiltered wastes that coated the roots.

As mentioned, produce results were not only significantly better with the 3n1 Aquaponics SIG System, but the soilless system was easier to maintain, easier to observe the results of experimentation – the real reason for using a small-scale system, and easier to watch how the aquaponics sub-systems work, simply and efficiently.

There are several messages on both sides this business card. On the obverse side, the graphic suggests to potential customers to tee up with our course. Our mission mantra is displayed below contact information. On the reverse side, several key value positions follow the title of our new course. Course attitudes announce the personal importance of appropriate focus to, and attention on the learning process.
