Seebd420answered grow question 3 years ago Would be absolutely perfect for drying mate :)
Your temp regulates at the sweet spot so your set, the cooler the dry room the more colour comes out.
You will need just a little fan nothing special just a cheap fan to get the air moving. But never aim the wind at your buds. You want to dry real slow.
If you have hygrometer, try get the humidity to stay around 60% - 70% for the first week of drying. Use the fan if humidity is too high and if its too low, sit a bucket of water in the dry room, or a humidifier.
On the second week get it to regulate at 50% humidity and under.
Your conditions otherwise sound perfect and i envy you as my dry room is hot and dry -,-
Best of luck mate!
