Chill man. I wasn't laughing you. I was laughing at my 'no heat' comment.OK i'm gonna make some adjustments ,
didn't realize it was so funny I'm just a newb learning the ropes its my first grow and i'm excited glad your laughing !
A little computer fan is what you want IF you want a fan at all. It just depends on your conditions.
You want to control the environment of the room you are drying in, not the environment in the box.
I have a couple boxes to dry in and in different ways but no fan. The box below can dry whole plan chop standing upright, A clothes rack put in with branches hanging on it or canna in paper bags with that clipped to the rack for a very slow dry.
If you want a fan, blow at bottom and suck at the top, for fan placement. LOL! <-------not laughing at you.
