Those of you who grow neps under lights in grow chambers or mini greenhouses I have a question for you. Are your lights covered by anything to keep the moisture off them? Reason I ask is because I have some pretty strong lights but it seems the plants are not growing at the same rate I see others. My lights are the florex kind from home depot so I have the plastic dome inbetween the light and plants. I was thinking to take it off, but wonder if it would harm the lights at all.
