Aquaponic Gardening

A Community and Forum For Aquaponic Gardeners



This group is dedicated to Aeroponic/Aquaponic combined systems where the roots are not growing in media. The photos are from Green Sky Growers in Winter Garden.

Aero-Aquaponic system video

Here is a short video of my "Economical" aero-aquaponic system.

Please ask questions!

I will make videos of how to make the specific parts or procedures, so you can make your own!

Here is the latest video update for my AeroAquaponic System, WOW the plants and fish have grown!

Happy Gardening

Hi All,

Here is a video of how to put the grow ports or any threaded fitting in the grow towers.!

Cool set-up. I think I'll build one sometime to act as a solids settler and growing area.

The sprayer inside the grow tower is just 1/2 inch PVC. I drilled tiny holes in the pipe. I tried many different irrigation spray heads including micro spray heads and even spinners that did not work. I think the problem is pond pumps do not have very much pressure. Pond pumps can have a lot of volume, if any one has any spray heads that work, please post

I am building a table to put the grow towers on using cement blocks and a sheet of plastic lattice. There will be about 16 to 24 net pots per grow tower. There will be 4 towers in this system connected to the 80 - 100 gallon fish tank stocked with 20 Tilapia.


If there are any questions please ask. The purpose of this group is to promote AeroAquaponics. I think one of the reasons more of us are not doing it, is because of the cost involved with the "Ready Made" systems. I have designed and built many NFT (Nutrient Film Technique) systems and a raft system over 150,000 gallons. The advantage of doing aeroaquaponics over NFT is the NFT systems are in pipes or small channels that get clogged up with roots, overflow and spring leaks. I have had NFT systems upwards of 4000 gallons...they get clogged up! The advantage over raft systems is oxygen, rather than having to pump oxygen into the fish tank and the hydroponic raft tanks the nutrient rich fish water will pick up oxygen as it passes through the roots of the plants in the grow towers. The volume inside the grow towers is more than enough for all the roots the plant wants to grow. Another advantage is the roots are not submerged where they are more susceptible to root born fungus and problems such as root rot.

This is the beginning of my Aeroaquaponic system. The tank is about 80-100 gallons. I am using a trash can as my "Grow Tower". You can buy a grow tower like the ones at Green Sky Growers for about $500.00 each. My work is to be able to build inexpensive grow towers with components from Home Depot or the hardware store.I will be adding a filter tank this weekend and stocking the tank with Tilapia.I cut 1 7/8 inch holes in the grow tower, I then used a propane torch to heat the holes and inserted a 1 1/2 inch PVC pipe. I applied upward pressure to the hole until it cooled giving it about a 30 degree upwards angle. I siliconed plastic cups with the bottoms cut out into the holes and inserted the net pots.

Maybe we could get a group together to take the free tour!

Comment by Patrick McKee on November 16, 2011 at 3:05pm

I have been trying to take a tour of Green Sky Growers

in Winter Garden. They are doing some remodeling and not been giving tours. I will post when I am going to take the free tour. When they are up and running it is on Saturdays at 10:00. I have been to Winter Garden twice on Sat. and it is a beautiful town with an awesome farmers market, free music, great shops and food. They have a splash pad for the kids and bicycles for rent.

Hi Eric,

Yes I agree, if you let the fish poopy solids get in the roots it creates a place for fungus to grow and oxygen won't be able to be absorbed, those two, are just the starters of the problems solids will cause in an aquaponic system. In the system I am working on there is a garbage can right next to the fish tank, the bottom is filled with window screen and/or some sort of mesh that will trap the solids then there is a milk crate on top of that with the pump sitting on the milk crate. There is a 2" siphon from the tank to the garbage can, the pump sends the water to the grow towers then by gravity back to the fish tank, clean and aerated. The siphon is on the bottom of the fish tank to suck up the solids and delivers it to the garbage can clarifier/filter. The water flows in the bottom with the screen above the discharge as to trap the solids in the bottom. Since the discharge is in the bottom and the solids are trapped in the bottom they will be able to gently move around but not get out. This moving action will help break down the solids and dissolve them in the process of mineralization. I want the valuable minerals/nutrients that are locked up in the solids; Manganese, Magnesium, Potassium, Iron, these are the minor or micro-nutrients, but they are no good in an aquaponic system until they become water soluble. You can also put a valve at the bottom of the can to release excess solids depending on the density of the fish.

Yes, one of the things TClynx has screamed into my head is solids-filtering the water before NFT. If fish poo gets directly on your roots you'll be in for a bad time. So what I've heard is filtering the solids through media beds. I'm not an expert, this is what I've heard. (this is my new slogan by the way)

Hi Eric,


Can you elaborate about filtering the water before a non media aggregate please.
