Its a small 8x8 storm cellar. Lights are on at night, and the daytime temps are in the mid 70's usually. Nighttime it gets in the upper 80's. I only have exhaust fans at 24x7, no intakes which I will change later after this grow is done. There are definite webs some are just under the leaves but there are three that had the webs covering the buds. A Vacuum is a great idea, I have a small one with just about the right amount of suction. I will do it tonight. I used my radio shack scope and viewed the little bastards but all of the ones I saw were dead!
