Got it, it didnt reach below 72 on my thermometer last night, but the humidity has been averaging 40-50%, not very humid as you can tell, so i just misted lightly and then put a slightly perforated ziploc bag over it. Hope It'll break soon! I Did a crap ton of research around durian growing, and I found a few forums mentioning some people who tried to grow durian in CA. Apparently, they don't mind our lack of humidity, and 40 degree weather, but the biggest killer seems to be Phytopthora as you guys said too. I'm just gonna leave it outside in the shade once the first few leaves have hardened off.
Thanks
