u want a GOOOOOOD LOOOOOOOOONG dry period. 9 days is a GREAT dry time, 10 even better....if ur buds can go that long without drying to a CRISP~! lettin the soil dry up will make for a shorter dry time. as for during the flush, i use mollasis to keep them feeding and it DOESNT change any of the dank taste, and at that it DOES help build those beautiful TRIKES!
