Kyle.......no, I never used LED's before purchasing the Gavita's. I just used HPS for many, many years.
Cohi.......I've been meaning to buy a meter, just haven't gotten around to it. But it's just another tool I'm not sure I need. After so many years, I can just look at plants and tell if they are happy, if they need anything, etc...... Last thread, I could tell the leaves were getting too many photons and were reacting poorly to me lowering the lights from 20 inches to 18 inches so back up they went. I study each plant everyday, it's very helpful in noticing small changes that are going on.
