I heard it does, I bought a cooling kit and now I can put my plants 12'' from the reflector, but am I losing lumens through the glass sheild? ALSO, I am not making clones yet, but what will increase my time/yeild without clones? Should I pack as many females as I get in my hydrohut mini, or should I LST the biggest 2-3? Does glass eat lumens?? How many? Oh yeah, I use organic too, so is a 2 gallon pot big enough for my final plant, or should I go all 3 gallon? Help me out, I need suggestions.
