I have a ballast but I was hoping someone could give me some more info on it. I would also like to know if it is possible to put a fan speed controller on the ballast to limit its power and keep it dimmed down. Would that hurt anything? I have included some pics. Is it Magnetic? Thanks
fan speed controller on the ballast to limit its power? ...no not at all as fan controllers are weak silly things(200-500w) and ballasts are like electric rockets(2000-5000w) use a couple of cfl's until plants are big enough good luck
