Proper curing makes all the difference in the world. When you put your buds in the jars its a good idea to get rid of any remaining stem. Fill the jar but not packed tightly. I leave them sit for a good 24 hrs and then check the moisture. If they are dry and crispy (dried too long), I throw something in there to increase moisture like a piece of carrot or fresh fan leaf or something like that. If they are too moist, I place them into a paper bag for a few hours. Once everything is going along well, I burp them once or twice a day for a few minutes and gently rotate the buds around. I do this for about a week then I leave them sealed for a few days before checking them again. I have found that 2 weeks is just a bit too early even though thats what most will say on here. I think its closer to 4 weeks to get the proper results but that is just my personal observations and preference.
Hope this helps
