100* is a bit warm. But MJ can thrive in 90* temps no problem at all...does not effect potency one single bit. As long as you have fresh air you'll be fine. If your plants aren't showing any signs of heat stress then keep at it, your bud will be every bit as good as if it were grown in 72*. The vast change in temps will also help stimulate flowering as long as they coincide w/the light cycle (lights=warm, dark=cold). Best of luck.
