I had really bad luck with some test buds I did to try the brown bag, and it didn't work at all for me. Tasted like hay and burned some much, you got a buzz from the asphyxiation from coughing so damn much.
I kept them in a cool, dark place with good airflow--everything I found out about it on the internet I did, but it just didn't work for me. I do live in a desert like area (L.A.) and elevation has a lot to do with curing.
I swear by the whole hang them in a dark place with constant but gentle cool air for 3 to 4 weeks, then jar cure. You can still smoke it about a week or so into the curing process, but the THC content goes up 400% after the curing process is complete, so patience is probably your best nutrient at this time.
But throw a slice of potato in the glass jar and leave it in there overnight. Your bud should be as moist as the day you picked it, and you can, sort of, start over again.
That's what saved my brown bag experiment, at least to the point I could smoke the stuff without choking.
