Wow! That does sound easy! A couple of questions though:
<UL TYPE=SQUARE>
<LI>What is the water level of the tub? Do you bring it all the way up and grow into the water? I know you say "very humid air" so I'm assuming that the roots would just hang down.
<LI>In this system, how big could you grow the plants and still have them be sturdy? Could you use this system for the entire process?
<LI>What kind of lighting do you use?
<LI>Kind of on the same thread, would it help if the container is lightproof?
</UL>
Wow! I'm ready to do this! Am I just being blind to some work or does this sound so easy and much more healthy for the plants(water/food when they need it!)
