My temps hovered in the mid to high 90's at the end of summer, and my plants did fine. I know that wasn't optimum, but it wasn't harmful either. Maybe it just slowed them down a little? IDK, they matured on time, and yielded nice, so I don't think the heat had too much negative effect on them.(a little, I'm sure) Try to bring it down closer to 80*, or a little under, but don't freak out if you can't. Unless one of those strains are really sensitive to heat, you'll be fine.(also, sativas do better in high heat)
