I swang into my local Harvest Moon (Hydro Store) to talk to the ever knowledgeable owner. This guy has been around the block. He has stories about teaching and writing curriculum on aquaponics and what not but said that he stopped doing it because of the growth rates. He said that they were far too slow. I am going to have to run light over my plants instead of the sun. If I'm doing this and the growth rates are too low it might not be worth it for me.

Has aquaponics changed a lot in the past several years that would allow the growth rates to greatly improve or is what he saying true?
