Air flow is always nice...
I dry my buds on a rack of screens... inside of an antique wood wardrobe...
I have a heater in there to hold 70F, a 6" circulating fan not pointed at the buds and a small exhaust fan at the top...
I have plans for a small carbon filter attached to that exhaust, but for now it just stinks up the house... and it's always half full cause of my daily harvest...
I get my fluffy buds dried in 2 days...
Fat Sativa colas in 4 days...
And the Indicas are so dense that they take 5 to 6 days and require spot on burping of the jars the first week...
I do not flush, but I do cure... usually 4 weeks is my preference... but believe me...
I smoke my share of uncured bud... especially with lots of Kief...
Cheers mates...
