outdoor drying box

give me some ideas. there will be a decent load to dry come october. i am limited in my indoor drying ability. generally i use a army surplus ammo box for outdoor storage, protects against animals and is fine for the long run in the vast woods where i live. so i would like to have a small box that i can run some battery powered heat that is safe, that i can leave in the woods and return in 6 hours, i'll make a box where the air can escape as it warms and the mj drys. but i know the heat will be nice and low. any ideas on a heater?

build a small fully enclosed room out of limbs and branches and such , dont know how much you need to dry or what weather you deal with this time of year in your location, but make a foom that has enough room to hang your efforts and allows circulation. if you can manage to stretch some very fine cheese cloth or screening you will catch alot of pure thc resin.mmmmmmgood

what is the weather going to be like. the heater is not the best way to go.but i dont know what you are dealing with enviroment wise. If you are secure from two legged varmints and can hang off the ground enough to stop other critters, you are better off with lots of fresh air blowing through .The darker the better but cant always get what you want. Can you set up a tent that would keep critters out and let lots of air in. Any caves around or small enclosed or rock coverings in the area?Can you hang out with it while it dries?
