I am really doing something similar without even realizing it...
I have 2 deep culture tubs that I dont have any fish in, but everytime I clean a filter, and I clean the filters in the tub pond with the tilapia and crays alot, due to the bag of hanging grass and the grass I feed the crays gunks up the filters pretty quickly.
The lettuces love that stuff, so I guess I will add some worm tea to the mix and see if things really go crazy under those lights
I do something similar as well. I replenish my deep water raft system from the fish tank water which comes from the grow bed that has worms in the grow bed rocks. Then I top off my tank with rain water. The raft plants are growing great although I do provide constant aeration and I have a very small solar pump that circulates the water a couple hours a day if the sun is strong enough.

Regards,
Bob

Are you all aware of this company? I ordered one of these for my fry to develop.
