Funny you should ask,I just posted this for Drella! One thing that I've found out (almost the hard way once) is that you can always trim a couple of fan leaves off of your plants and pop em in any jar with bud and a day later it will be re-moisturized. However, you can't do anything about moldy bud once it's moldy. I always make sure my shit is very well dried before I jar it. This way it will keep for months without any degradation. OH, and btw the dankness comes right back with the moisture when you add the leaves. It will smell very bland when it's very dry, and then when it gets more moisture it starts stinking. They say optimal moisture level for long-term storage is 5%. For smoking however, optimal moisture level should be 10 - 12%. If you re-moisturize the bud up to a higher percentage, when/if you sell any you will make more money with more moisture in the bud. My guys get really good deals cause I'm too lazy to do this for em. lol Anyway, behold the cut-and-paste...
One actually wants their buds to take time to release their moisture gradually. Chlorophyll takes time to break down, and I read is somehow then carried away by the evaporating water molecules in the plant matter. So if the water molecules dissipate faster than the chlorophyll can break down, they dissipate alone without taking the chlorophyll along with them, leaving the chlorophyll in your bud making it harsher. They say a rel humidity of approx 50% and a temp of 65 degrees is best. Hang your buds from where ever IN THE DARK (I hang mine from the racks in the closet because I have the doors removed), and put a fan in front of the buds about a foot away blowing AWAY from the buds so that it is drawing air through them rather than blowing on them in any way. Hanging prevents further disturbance of trichomes, and also allows the air to surround the buds entirely keeping mold at bay. Just put the fan on med or med-low, the lowest setting that you can get away with using. You want the hanging trimmed budstalks to gently sway just a tiny bit showing that air is passing through them. Keep them spaced so they at least do not touch each other. They can be very close to one another, just not touching.
After about 6-7 days once the stems snap when bent (the lower branches that are really thin and spindly always take the longest believe it or not) you can start slowly trimming all the actual bud off the now dry branches, placing it into large mason jars. I never fill any jar up over like 2/3 full, you want a little room in there to move it around some every day when you burp them for the first several days after jarring. I just snip off the top cola portion first, then continue down the branch removing the remaining buds.
Once every thing is jarred up tight, for the first 3 days once a day I 'roll' the jars to agitate the bud inside and to loosen it back up again (it will have compacted down into a sponge by now), and then open the lids for about a half an hour. After that, just put the lids back on tight and put the jars back into a completely dark location. Light degrades THC.
