if you wanted to do the entire growth process in the system, I'd use much sturdier tubing to suspend the plants, at least when they get larger. I did grow one plant in the original aero system for 2 months, w/ no problems (roots were 3' long when I took it out...wrapped all the way around the tub)...the water level is something to play w/. I started w/ it about an inch below the cuttings, then brought it down to 3 inches w/ great results, I'm too chicken to try further away...lighting is simple, you can use anything from floros on up...and you don't have to worry about at sprays or a 'dome' to keep the moisture in...
