Heck, I've had basil growing pretty much in just it's own roots and a plastic pot getting constant drip of filtered AP water.
This is a different video on the NYC Science Barge: http://www.youtube.com/watch?v=wF44p7FG2AQ
One of their main focuses is to show that plants can be grown in any medium with just water and nutrients. They included a shot of basil growing in Legos. Thoughts?
Well, drat! I started up my system and noticed two things: My drainage hole is too high so there's too much water in the beds (would be better for water input), and I sprung a leak.
Should I just buckle down and lay the beds atop two 2x4s and let gravity drain it from holes in the bottom, sacrificing one of my hoods and lights? Or does anyone have any other uncomplicated ideas? I thought about a drip tray but decided it wasn't worth the trouble.
Couldn't you just drill another hole lower in your tray to lower the water level? As for the leak, is it hard to find? Because can't you fix leaks with silicone caulk?
The leak is in the silicone. It didn't dry all the way through or something. The first problem with drilling a second hole lower is that I couldn't drill one large enough to accommodate the tubing without running off onto the bottom of the tub. The second is that I would need to prop up the grow beds to sit up higher to get the water to drain into the tank and perhaps put more holes in to get it to drain in an appropriate amount of time.
I set one of the grow beds on top of the tank with drain holes in the bottom and it seems to work fine. Now to figure out a way to get the second one to sit there without crimping the air tubes.

OK, I can see a pretty funny contest coming on here of what is the most bizarre media anyone can grow in. I'm looking around my kitchen and thinking that pistachio shells would work, and packing peanuts....
Can you post a photo Emma... it might help us figure out the options available
