Given that, with your temps, I'd say bump the humidity up if you can so long you can provide adequate air flow. 70F @ 65% RH should get your dry time ~10 days. You'll still lose some
terpenes, but it won't be as bad, and you might want to evaluate your cure process. Here's what I've found makes for reliable results (I spent the first 10 years of growing in the desert, I get it):
- Hang dry till the stems crack but don't break. 5-7 days.
- Chuck buds off the stems, into paper bags. Burp the bags daily based on feel. If the buds feel wet, twice a day. Continue till they're crispy outside, but spongey feeling. Average 5-7 days.
- Into jars. Burp daily for five minutes. Kick the buds around a bit. Terpenes should start expressing themselves after a week or so. At this point they're ready for use.
Where I was, average day temps were 100F+, RH averaged 30% year round. Using a paper bag while the buds were still relatively wet in the middle was absolutely vital for a good, usable product within a month's timeline.
