I just harvested my first grow- it was tiny i ended up with two 1.5 ft. females in my cupboard with a compact fluorescent light. now im moving to a new space that has a higher ceiling, so i can use a HPS light this time. However, this is a tiny space too, so it will still be tight. Anyway my question is will a glass pane over the bulb reduce heat stress so i dont burn the top of my plants if i cant tie them down? how about keeping a fan on the light?
