I see its been asked a few times but it wasnt answered I dont think, I went through twice but I was just curious how long you leave your jars open? I've read 10 minutes, 2 hour and 4 hour cycles, I've read some pretty weird methods without ever really following one particular or really finding an absolute answer. But I am curious how long you and the mrs. recommend leaving the jars open for.
After hanging for a week in a dark area with air circulating lightly, at 60%+ humidity. I then jar the bud, which is at around 70%. Meaning if you enclose these fresh buds in a jar with a little hygrometer (measures humidity), in an hour or so they'll register 70% or more. That's high, and so those jars I'd leave open for 1/2 hour, and do it twice a day. I really like to bring the moisture down slowly, but I'm more aggressive with the open-lid time until I'm below 70%.
I also separate big colas from popcorn, since popcorn dries faster. The fat colas take a long time to get that core dried a bit. I use 1/2 gallon mason jars, as I don't have a large grow, just for me.
After the Rh% drops below 68% I open the jars for maybe 15 minutes once a day. This draws down the moisture very slowly. Like maybe 1 point a week drop. When I get to below 65% I open just enough to burp it. Sometimes I inhale the air in the jar to hurry up the air exchange. So the lid is off maybe 15 seconds. I do this burping maybe once or twice a week.
I spread this curing over the course of months. I may vacuum seal the jar at that point to remove O2 and almost stop the curing process.
