Drying Temperature and Humidity

Awesome discussion here growers! I just wanted to recommend Waykar brand for dehumidifiers. I run this one https://www.waykar.com/collections/dehumidifier/products/155-pints-commercial-dehumidifier-with-drain-hose-industrial-dehumidifier-with-a-1-32-gallons-water-tank-in-large-space-up-to-8000-sq-ft-for-warehouse-basements-whole-house-moisture-remove
Its in my room that is 11×5 with 18 3gals in fabric pots. It runs alot and sometimes the AC kicks on because of the heat it creates. Once plants are to size I was pulling about 6 gallons every 24hrs out of room. At that rate it’s essential to run a dedicated drain line or else you be a slave to emptying your dehumidifier reservoir, and if you forget the dehumidifier will automatically shut off, which is not ideal for the grow!

Just dried 4 plants in a bedroom closet. Fan for circulation and a humidifier to slow down dry time. My temperature was between 75-80°F (In KC this time of year 74°F is about as cool as my HVAC will keep my house). I made the mistake of setting the humidifier to target 1.0 VPD. I should’ve set it higher, 1.2-1.4 , for the first few days to get the outside of the buds to dry faster and start the wicking of moisture from the stems outward sooner. Then increase humidity or lower VPD to slow the drying down at the end. I say all this because this morning I cracked open a hand grenade sized bud and found a little mold near the stem at the base of the bud. Lesson learned. Saving terps isn’t always the best approach. When you’re making do with the resources you’ve got, always remember to think about which controllable variable is paramount and realize in a home grow you can’t always dial it in ideally.

I’m in day two of drying my first harvest. My tent is around 66-67F and 55% humidity. The problem is I did not factor in the 3 fans I had running at the walls (on high) would dry my buds so much (even though I should have). My question is can I still save my harvest by turning the fans down (I shut one off) and the other two are circulating air at the walls 2 feet below the bottoms of the hanging plants; and also by raising the humidity to 60-62%? My plants are not completely dried out yet, (stems still bend not snap), but I feel like I was a day away from disaster, if I hadn’t reacted.

Yes you should be o.k., the time during witch your conditions were not right did not last to long, you want some air movement but not wind, like you said good thing you kept watching the drying conditions, certainly the firstnday or two, but as long as the stem has water to express, you get some leeway, unless you kooked out all the terps… keep on growin mate!

A lot of peeps seem to be drying with around 60% air humidity, nice and slow, i’v never used sophisticated devices to monitor drying, but one thing for sur is you want them to have kleen air, the drying flowers will absorb the ambient conditions, so kleen space and air quality are key.
