100 is NOT too much, I've seen temps over 105F that lasted for 3 full days a number of times in my room with no other results than the plants grow faster than usual. Yeah faster. Plants don't slow down at higher temps, they do the exact opposite, they grow faster. Fast growing in itself can be a stress if there's either too much air movement or not enough water or some other thing that limits or maxes out transpiration. It's the speeded up growth at higher temperatures that make the plant use more CO2 during photosynthesis.
I must disagree also. A plant can overcome three days, but a consistent hot temperature definitely slows things down. And I know that by experience. The OP never said he uses CO2, so using up the CO2 faster just makes it deplete the air faster. I wanna see someone do a side by side..... but it won't be me; because I'm not ruining another crop with high temps. I got my temps down to 82 consistently, and things have taken off completely. Maybe a day or two of 100 degree weather might make them grow faster, I dont know... But I do know that consistently hot temperatures for a whole grow will stunt your buds big time....
