vertical anyone?

Does anybody have any vertical PVC aeroponics experience?

The grower Heath Robinson on this site grew some crazy shit in his homemade vertical grow hydroponic PVC system, I know it's not aeroponic but he sure as shit knows what he is doing. Grew two critical mass plants hydro in buckets, "vertical light style" and got 2 pounds off one plant and 2.5 of the other xD If you don't believe me just look him up. I'd link you but RIU wont let me search anything for some reason :/
