u should flush it a bit more to get the better taste out of the bud, and 4 days is just not enough time for ur bud to even dry. do what bonbon was saying and get it in a pitch black room thats fairly cool and well ventilated! one method for getting better trichome production is to put the plant in a dark closet while still alive, and leave it in there for a full day. u will notice a difference in the amount of crystals. u can even flush the plant while its in the dark, but try avoiding getting the plant in any light!
