Dried Too Quickly? Humidity Question for Curing?

Let an Auto GG sit in dark, without water for 2 days, to start the harvest/drying process. I harvested the plant in 2 sections(top/bottom), over 2 days. I cut off and trimmed the top section, and hung those up to dry on Day 1, in a basement room that has a dehumidifier(barely ran) which has the room at a steady 79ºF and humidity at 53%. Day 2, I cut off the bottom section, trimmed these and hung them up to dry. On day 4, I checked the ones I hung up on day 1, and was surprised to find them drying a bit too fast. This might be because I started the drying process, 2 days before harvesting and I think I always trim too much. I mean I gently spread apart each bud on the cola to trim the sugar leaves that are hiding down in there(the ones that are sometimes a very light green from lack of penetrating light), deep inside the dense cola. This leaves the cola with more room for better airflow.

I decided to put day 1 flowers in a same jar with ones from day 2, in order to have the moisture pulled from the soft ones, and make the dryer a little softer. I did this to try and lengthen the drying time for the ones that dried a little too fast.

The day after I put them in the jar, and after opening and replacing the air a few times that day, the humidity bounced up and down for a few hours, the humidity in the jar remained at 69%. The next day I did the same procedure to replace the air in the jar, and the humidity ended up a steady 66%.

Does anyone know at what temperature and percent humidity, can mold start to grow on buds? Should I just keep doing what I'm doing for "x" amount of days, because the humidity is lowering, day to day or do I need to put any of these back up on the drying line? What is the magic number for humidity, when I can start leaving the jars closed, to cure? Thanks in advance.

20170927_111355.jpg You will be fine as long as the humidity in the jar is 70% or less. Burp the jars twice a day while at 70% until the Rh gets down to 68% generally. After that burp em every other day until 65% then weekly until 62% then leave em to cure the rest of the way!

Try to keep the temps at 65* or less and keep your jars in a dark location

I was wondering this myself. Since I'm coming up to my first lot of worthwhile stash to cure. Cheers for the info.

jarring wet plant material in 69% RH is ideal for mold.
its fermenting in there.

why not lower your temps in to correct drying temps, adjust your air flow and control your humidity in your space.
I do that and a few weeks later its done, ready for long term storage or to use. no jars, no fermentation and no mold ever.
I found perfect ideal conditions in jorge cervantes grow bible been using since day one no issues.

So- 40% +/-?

Yep your temps are too hot, Google "water activity" and "moisture sorption isotherm curve". The perfect cure every time guide focuses heavily on RH but temp is just as important because desorption rate is what really matters.
