Hey guys, this is my second grow, the first being very well funded 4 plant 600watt hps grow. This time it's a little more poor man style. I have a small closet that I'm using a corner of for the grow. I have a 150 watt hps lamp, and have a mixed variety of strains, and I will keep only the strongest female. Any who, temps staying at 75 and they are already growing, my problem is light leaks from the closet door, I have a tarp Velcroed on the inside but light comes through the tarp. What do yall think? Also how can I fix this issue or will it matter?
