ive always harvested in the morning, but never had the size you are working with....ive always dried mine just strung up in cardboard boxes in the top of a closet or in the attic or something, never worried about a fan, i dont have many 75+ degree areas with humidity over 65% in or around my home so mold never really worried me....recently though i dried a few sample buds in a jar just with the lid off, (i could still see the bottom, very sparsely laid out) and they took like 10-12 days to dry b4 i could jar them but they were head and shoulders above the rest of that plant, soo smooth, almost like hookah or something, idk if it was the super slow dry or what, but im trying it again with a few more buds to see if thats the trick
