Plants in dark room low temps

FWIW I would NOT put in a heater, but I would install a fan to keep the mould spores moving and if I could, I’d check and maintain humidity levels on the low side to hasten natural drying. 😊

16C wären ideal je kälter desto besser je länger die trocknung dauert desto besser fan nicht AUF DIE KNOSPEN richten nur das die luft nicht steht

When drying humidity around 50-60% with some airflow. it will naturally tapper down into the 30's when the buds dryer in a more enclosed environment. For curing I like to keep mines around 55-60% anything over 65% can increase chances of mold from my understanding. If it starts to smell like ammonia or cat piss, scatter them on a sheet and dry more before curing. Don't forget to burp. bets of luck

The cool temperature is not a problem. It just means drying takes a day or two longer. I dry until the large stems make a cracking sound when bent but they do not break. Then I put the flower into airtight containers and adjust the humidity to be 58-62% for curing. If I dry long enough for the larger stems to snap or break when bent then the flower is usually too dry.

Thanks for the info. What should the humidity be at? Around what %

your temperature is 20c, your retaliative humidity or RH% is 40%?? cant tell from the image its washed out. If you want more humidity add in pans of water on the floor or wet a towel and hang it to dry in the room. I like to dry inside my tent if I can. Other option is adding in a humidifier if you want your humidity above 50% Best of luck
