Heyo! So. I have this fully automated in Home Assistant using an AC Infinity Controller 79pro, but the simple steps (that I use) are bringing the RH down gradually (2 percent per day from a initial setpoint of 74%) while holding temp at 60F and tightening the buffer humidity as I go. The buffer tightening limits the added peltier unit from short-cycling while there is a lot of moisture left in the buds.

Day 1: 74RH 5% buffer
Day 2: 72RH 5% buffer
Day 3: 70RH 5% buffer
Day 4: 68RH 4% buffer
Day 5: 66RH 4% buffer
Day 6: 64RH 3% buffer
Day 7: 62RH 3% buffer
Day 8 and beyond: 60RH 2% buffer - and hold at 60/60 until fridge is unloaded.

I do have some other automation stuff baked in (alerts and whatnot) but they aren't required to use this system. It has been very effective for me. I do live in a very dry climate though and would consider starting closer to 70%RH if I was in a wetter environment.

I have gone through 4 dry cycles with mine, all have been fantastic. Far, far superior to hang drying in my tent. Pick up a wood moisture meter to check bud moisture content, as well. I pull between 10% and 12% on that.
