I just did a harvest and pulled one and let the other sit for an extra 36hrs and I didn't see any difference between the two. I have heard that mold can grow quick during long spans of darkness while still on the plant. Hope this helps.
This one takes a bit but its never failed me.
I get a lot of daily newspapers that are often left on front porches.
Wrap small amounts of bud in them and make my trip.
