thanks for the reply. I think if i could do it any way i wanted i would use higromite. Is that stuff as good as they claim? I dont think i can afford as much of the stuff as i would need, and man rockwool is cheap. Decisions decisions. If you guys say its worth it to go with the higromite or hydroton over cubes i would have a hard time not going that route. I posted this in plant problems and i didnt get a response and im really desperate for some info. Ill post a pic of the problem. Its spreading from bottom to top and really starting to scare me. Im thinking about cutting the lights back to get them to ripen and harvest asap before I lose everything. The black spots are what really scare me. Thanks again.
