siek
I also dry in a shed. I have dried in temps from 40F to 90F. At higher temps I do not use a fan at lower temps I do use a fan. I check them daily. When the buds are a little crispy on the outside I jar them. Once jarred I bring them into the house for the cure. Keep the jars in the dark and burp until the moisture level is where you want it.
good luck
