you will need some kind of air circulation even if its passive, ie a whole in the floor and one in the roof. Warm air will rise and exit pulling cold air in. Do Not let it get higher than 84degrees. 28 or 29 c. It would be better with a fan. VV
I have dried several times this year with no fan. Had them hanging in a portable closet with virtually no air movement. They were dry enough for jars in 4-5 days. Worked fine for me, but the humidity level is fairly low in my area.
what u do is go to like walmart and get one of those desk fans......worked for a friend of mine who had to cure them in his closet. think it took like 2-3 days
u guys talked me into the fan idea. I will have to use a 12 volt fan with my solar panels and batteries.
the other problem is they will have to go 5 days until I can get back to check on them.
