I dried mine in a closet as well. Keep the door cracked open, put a fan blowing on the wall of the closet that circulates to the buds. May have to run the fan speed a little higher to keep humidity down if its really high. It may dry your buds out faster than you'd like, but I've never gotten molded buds that way. Also make sure buds have space between them when hanging or if in a tray. Don't let the buds rest on each other because then no air can get between and you could get mold.
Best of luck! Happy growing!
