i do a 3-4 week dry of manicured buds. to do this i keep the humidity level above 65 below 75%. THE MOST IMPORTANT FACTOR IS GREAT AIR CIRCULATION. thats whats going to prevent mold from growing. i use my grow room to dry so i keep the exhaust fan on and have an oscillating fan blowing over the tops top the buds that are sitting in dehydrator type trays. turn buds every couple days, slowly drop the humidity after 3-4 weeks to a stable 55-60%, jar'em up, burp every couple days, then i use a pump-in-seal to vacuum seal. check every couple months
