Yes, the reason for putting them in the jars is for 'the cure'. The cure is what gives the bag appeal, the good scent, and the smooth smoke. In most cases, the longer you cure the weed, the better it is. The only thing I haven't seen up here so far is that you shouldn't cure in the light, a dry dark cabinet is perfect for curing, just a regular kitchen cabinet works great, open each container for 5-10 minutes a day (not even that long really, you just need an air exchange to make sure the moisture is out). After a few weeks you no longer need to do this, and the shelf life is just short of a year. You can also vacuum seal this in plastic containers (best method) and then freeze, extending the shelf life even more - You CAN use the vacuum sealed bags, but the bag effect of that is mexican schwag, really compressed sad buds, instead of big happy buds.

This is known as the typical 'cure' which most people use for harvest, including most commercial growers. If your doing it for a pure medicinal effect, there are different methods of curing, but I'm not going to get into it right now, most people would call me a moron for what I do to my strong harvests.
