Cookies n Creme [Mephisto Grow]

Going through a substantial and extremely extended heat wave here in California, so it's been very difficult to keep temps low. I'm seeing it climb to the high 80's in the tent with the light on, and even with a portable ac on, it's hard to keep the temp low. The plants look healthy but the worry is potency! We know heat affects that. Overall, did re-training, did some minor defoliation on Cookies, and things are going well.
