Well, I'm doin' it right now (like doob, I,m using tomatoes) but still this concept seems foolproof so far!! For lack of $$$ I'm using vermiculite and perlite for a medium. There setting in a plastic strainer with really small holes. The tub was purchased at the dollar store,(dark purple in color,no need for the black tape)3 bucks and holds 4 gal. 2 airstones and 150w hps and these tomatoes are going ape sh*t!! Almost twice as big as the ones I planted in dirt at the same time. Never could get the ph quite right, a little on the acid side, but the matoes don't seem to mind, suggest taking more time to correct ph for the real deal though!! peace
