I am also interested in this subject, and it has been the topic of many hours of research on my part, yet mostly unanswered.

The short and simple answer is YES, certain plants will work best in flood and drain(such as root crops), but I have yet to see any research doing head to head comparisons of various crops, in various aquaculture/aquaponic setups, and would find that interesting to see done.

Over the next few days I am gonna start working on a new thread with my idea for a testing greenhouse I have been contiplating in my mind, taking into account various growth methods found all over the net. Once I start it, I would be interested in any input you might be able to include.

BTW...my aquaponics knowledge is solely research based, but I do have years of garden growing, and aquarium background knowledge to pull from. I have yet to put into practice aquaculture, hydroponics, or aquaponics
