I just harvested a little over a week ago and jarred the bud at 7 days. I have been burping as required, put a couple of boveda 62 in and my calibur 3 constantly reads 70% or more. I really don't think the hygrometer is accurate. There is really no sign of moisture in the bud, it is losing the grassy smell, seems to be curing perfectly in my newbie opinion - this is my first cure. So i took the bag with the boveda packs, but the calibur 3 in it, sealed and and it SHOULD read 62 withing 24 hours according to the boveda site. They sell a kit to calibrate hygrometers and it is a sealed bag just like my 10 pack arrived in and 1 boveda pack. So after 24 hours, I will treat what ever RH% as = 62%. I have read that hygrometers under 70% rh can be inaccurate. We shall see. So I just wanted to pop in with another use for the Boveda pack!
