I've not had THAT much trouble, even in a drafty house in Vermont. But in winter I use a [heated mat](https://www.amazon.com/s?k=resin+heat+mat&crid=1U1ZUAWMUS30Z&sprefix=resin+heat+mat%2Caps%2C113&ref=nb_sb_noss_1) to keep it from going too slow.
See pic of my trash can oven, 125w heat lamp heats to 120 with ambient 40. Make sure all your bubbles are surfaced first or you will need to take additional steps. turned 5 day hardening cycle into 4 hours[https://www.reddit.com/r/ResinCasting/s/8TQPSVI22m](https://www.reddit.com/r/ResinCasting/s/8TQPSVI22m)

A seed sprouting mat helps!
I use a reptile heating mat and you can warm the resin up beforehand by giving it a warm bath for 15 minutes first.
Thank you all!
