It depends on the strain. The best genetics are ready to smoke as soon as the bud is dry and stable. A long cure might improve it a bit, but many smokers might never be able to discern the difference. Other strains need a good long cure to really let the flavors come through. I had one strains that just seemed like garbage to be after it was dry. I put it in a bag, and really kind of forgot about it until I was running low on weed, and the wife tells me that she the big bag of weed I had forgotten about. I decided to roll up a joint of it, and it was way better that it had been before the 3-months it sat in the bag for.
