I had a question about the omega style gardens that rotate with a light in the center. For one, it looks like most systems just use large size rockwool cubes for medium but is that the only thing the roots grow into then they light prune and stay in the cube? Also, if this is the case, wouldn't less roots (because of the limited cube size) mean smaller or shorter plants? I am considering doing an experiment with this method with some simple wood setups and CFL's. My other question is, i heard a few places the optimum time for rotation is once every 50 minutes, wouldn't this not give the cubes enough time to dry out? When you do E&F most people do 2-3 waterings a day so would the rotations be to often? In any case it's a cool system and i hope to get to play around with it one day soon.
