Well i'm in. Here's a question for the w/f folks...two actually.....what kind of medium are people using? I know the round clay stuff is popular (Hygroton?)...I ended up using something called Higromite....looks kind of like natural rock; made mostly from silica. Want to know how happy folks are with their medium of choice. Also whats the biggest sized plant people have tried transplanting into a w/f bucket; how did they accomplish it, and did it work ok? Did they transplant from soil or another hydro system? I always use those rapid rooters and small seedlings but would like some input on transplanting something larger into the system. Thanks!!!!
