I know NOBODY that uses these. It's pots that water the roots from the bottom. It's a cheaper hybrid hydro system. Too new to really say if they work well and in my opinion too risky to be one of the first to give them a try. That testimonial section looks fake. Look at that one picture of some dude standing next to his huge flowering plant with crap t8 or t12 florescents hanging over it in some unfinished basement. I have just heard nothing about these and I've been doing my homework. I remember coming across that white haired guy in a youtube video, I watched about 30 seconds of it and moved on as it reminded me of some late night infomercial. For all I know they are AWESOME, but they're probably just a gimmick much like air-pruned and fabric pots.
