Optimal drying environment is 60 degrees with 60 percent humidity. Anything will work, just don't let them stay under 55% humidity once they've dried or the curing process will get f××ked up. This is what I struggle with still since in in a place in the states where the damn temp and humidity swings are nuts from day to day.
At the end of the 3rd day, pop open a bag and check them. Its been taking mine 4 days but temp was 74 on Thursday with 77%humidity and it is now in 40s with 100% humidity. Sunday gonna be 15 and won't be shit for humidity. It'll be a lot better in the tent in controlled environment...
Check out the drying/curing thread for all the info you'd ever wanna know lol. For key, getting this part right is harder than actually growing the damn things lol
