Maybe some folks can chime in here on recommended RH for a larger space. I typically use shoe boxes filled with shredded brown bags. You don't wan't to dry out your flower too fast, and don't go to jars based on # of days, the stem test is important
A bigger area, I'm guessing youd want a higher RH, like 55%? I'm not sure, let's see who chimes in.
I know we have some excellent tutorials on curing here, I can't for the life of me find them right now.
