You'll need to do you're own research on growing media, plants, and nutrient solutions. I'm still a novice, so I don't want to misguide anyone.
I'm using a mixture of clay ball, perlite, coconut coir for my media and Botanicare CNS17 Hydro Formula Grow for my nutrient solution.
Pictured is sweet basil and cilantro.
[EDITED: this is no longer valid. See below] A key point I found to ensure you get pumping of the water up the tubing to the top is to make sure the bottom opening of the T-connector that is open to the nutrient solution in the base is pointed down and as deep as you can get it in the tank, which is why I created the TankTubeHolder and glued (with cyanoacrylate) it to the bottom of the tank.
[EDIT] I ended up drilling a hole towards the bottle of the tank and epoxying a tube in place to feed the water to the air lift T-joint, which is now outside the tank. See the new photo and video of the air lift system.
Let me know if you have any questions.
