To tell you the truth I have no clue how faraway my light is, lol. I raised it for the pics but normally I have my light height according to my temp. My last grow op in the othe dryer I made 8 females convert to males because I couln't get the temp out of the high 80's, and there were a few other stresses and since I didn't know much about sexing I didn't know what I had done till the sacks started to pollinate, lol. After that I swooreagainst growing but that sure got me far. Butyou are right the are a little more stretched then I would like them to be, but the temp is sitting at 79-80 so I guess I'm playing it a little safe. Do you think 84-85 would still keep them pretty happy if I move it gradually?
