That system will give you monster plants & root mass. However, if you do not convert it to a re-circulating system, each bucket will have a different ppm & ph. I have seen plants 4 feet in diameter with this system (thats switching to 12/12 @ 2 1/2" feet tall) There is actually a system on ebay that is the GH Waterfarms converted into a re-circulating system. Its a real pain in the balls to constantly checking each bucket especially when its full of roots.
