Slowing Down Resin?

Hi Folks,
I am a new member and live in the USA. I have a problem with my resin mixture going off too soon. I bought (medium) speed resin. It is supposed to have about 25-30 min pot life at 80deg. I live in South Carolina, and 80deg is pretty cool this time of year! The temp is expected to get to close to a 100deg this weekend, just as I plan on doing a lamination project. My question is how can I slowdown the reaction of the resin? I will be working outside, so no A/C to help. Would placing the resin in a fridge before mixing help? I know I can't reduce the hardener ratio to slow it down. Any ideas?

Thanks very much for the advice Guys. Great info. I plan on starting a first light, so should be cooler, and I will dived resin into smaller containers. First time I worked on CF I had a "runaway" in only a 16oz pot that was pretty full. I thought What the hell?
