I grow in AZ and have a problem with low humidity.
I use a humidifier I got from bed bath and beyond https://m.bedbathandbeyond.com/1/1/1020-boneco-air-o-swiss-ultrasonic-digital-humidifier.html
I simply chose the highest output per day unit. It's super easy to get a 20% off coupon for BB&B
Then I have a spt52pe https://www.amazon.com/SPT-SD-52PE-Energy-Star-Dehumidifier-50-Pint/dp/B00DMBIAD8.
The dehumidifier has a hard 1/4" line it comes with. I run it to a sink 15ft away and just jam it into the drain. It'll automatically pump away condensation. I set the dehumidifier to 60% and set the humidifier to low in the very beginning and as the plants don't humidify the room I'll gradually turn it up.
Also I have a 420cfm fan on a can 66 to keep the air from stinking too bad and also to keep the air free of mold spores or any nasty shit.
I crank the AC down to 68 in the house and divert the air and it keeps my drying room at 60f and 60% which is ideal. I dry for a week before I start trimming and stuff will hang for as much as 18 days and smell phenomenal just hanging.
