hey dude, juicyfruit is a MASSIVE yeilder, for me at least in a sog straight from rooted clone to 12/12, I got about a 1/2 ounce dry off each 10" high bud stalk under a 400w hps with homemade soil and all organic botanicare nutes. IT looked like they were a bounch of 2 liter bottles. Also If your going for the big plants, definately a little bend and a top will do er great.
