Guide To Building A DIY Indoor Aquaponics System

With the depletion of agricultural land for farming and the introduction of Genetically Modified (GM) crops, it’s necessary for us to produce our own herbs and vegetables in the absence of sufficient land space for cultivation.

Do you want to know the simple solution to this?

Aquaponics.

The rise of DIY indoor aquaponics has enabled gardeners to grow plants by fertilizing them with waste water from fish in a closed system.

Aquaponics is a combination of aquaculture, which involves growing and breeding of fish, and hydroponics, which refers to cultivating plants in water without soil.

Building your own aquaponic garden is a revolutionary way to grow organic vegetables, greens, herbs, fruits while using fresh fish as a great source of protein.

Materials Needed

We have to choose the right materials in building our aquaponic system. Here they are:

  • 20 Gallon Aquarium. For example, Tetra 20 Gallon Complete Aquarium.
  • Industrial grade heavy duty shelving.
  • Plastic storage tote.
  • A water pump like Homasy 80
    GPH Submersible Water Pump.
  • 4 feet of inch silicone tube to attach to the water
    pump.
  • 2 inch ball valve to attach to the silicone tube.
  • 10 feet of inch PVC pipe.
  • Four inch PVT T’s.
  • Three inches PVC L’s.
  • Three inch PVC end caps.
  • Two inch PVC threaded female ends with male plugs.
  • Two inch bulkhead fittings.

How To Build Our Aquaponics System

First, test your water pump to be sure it works and pump it at the height you need. Also, make sure you have the right size fittings for each of your materials.

Cut down the pipe pieces and drill holes into the end caps to assemble the siphon. Drill hole into the grow bed container so you could fit the bulkhead fittings and the PVC pipes through.

Rinse your aquarium gravel thoroughly before using it.

Set up the tank without water and start working on your grow bed. The tubing that comes from the aquarium pump should go into the grow bed about 1-2 inches under the top layer of growing media. It’s advisable that the top layer of the grow media be a dry layer.

When you do that, the siphon will kick in when the water rises to its level, and it will suck down the outflow pipe back into the aquarium. Place a PVC at the end of the pipe to increase suction. The water will be brought up again by the pump and the cycle will be repeated.

Some aquaponic systems perform a full cycle every 5 minutes.

The ball valve on the tube is to control the pump speed. If the water goes too fast, then the siphon won’t stop siphoning and the grow bed won’t be filled with water. You might need to make some adjustments to get it
right.

Start Enjoying Your Aquaponic Garden

Now that you’ve set up an aquaponic system, you can start enjoying healthy, safe, fresh and delicious foods all year round.

Aquaponic systems are purely organic. They are 4-6 times more productive and use 90% less water than conventional gardens. Did I forget to mention that there’ll be no need for weeding or fertilizing?

Eat and stay healthy with your aquaponic garden.
