I never worry about that really....perhaps I should.
I just hang'em up, check in 3 days or so (who am I kidding, i'm down there about every 6 hours looking at them) and when the stem BENDS but doesn't snap....and the feel a lil' crunchy on the outside....I jar them up!
Stick a caliber III in the jar and burp til 50-60%RH. Let it sit for weeks and then enjoy all the hard work and patience!
