indoor curing

I have been hanging my plants in a large cardboard box with a boxfan on very low speed on top, 75F' 35% humidity. They have been drying out in 3 days. I then put them in a mason's jar and open the jar for about 10 mins a day for about 7 days. I am always looking for a better way, any improvements?

Not that it's better....just a bit different...I use a large tote, install a 120mm pc fan in one end, drill holes in the other, hang a wire grid inside...hang my harvested plants in the tote for 4-8 days...I exhaust my drying tote into my grow tent to handle the odor through the char can of the tent....When I jar, I check often the first day to check re-moisturizing...if too wet, nuggs go to a paper sack till moisture is to my preference....back to jar.....I only vape so I prefer my nuggs a bit drier.....

i would make sure that the fan is pulling air out of the box as opposed to pushing air in the box as an improvement on THAT method. I hang-dry mine in a closed off room like a closet or slightly bigger, complete dark for anywhere from 4-6 days. Til the stems almost snap. I dont wait for the full snap. And after that its into a jar in the same complete dark room. Next day, I open up the jar, spread out on paper towel for a couple to a few hours in same dark room, re jar and then burp for 15-25 minutes, 3-5 times a day. The burping becomes less and less over the course of 3-4 weeeks.

what temp should the curing room be? I have also read that you should vary the temp by 10'F every couple of days?

I have cut vents in the bottom of the box and the airflow is blowing downward into the box, escaping out of the vents on the bottom.

is 56F too low for curing in the jars?
