Cardboard box drying outdoors?

I wouldn't do a cardboard box. If it rains you stuff is done for. I you get a plastic tote or something. Drill holes in the side to slide a bar through, then hang from the bar. Squeeze a fan underneath blowing at the buds. Then I think you'd be good. I would also worry about bugs and such

Hey Growmie, I've personally used a cardboard box to dry in so that that part will be fine, but what you'll need to watch for are the humidity and temp and make sure they are staying in the correct range, which could be the tricky part since your actually drying room is outside, you'll have to take in consideration the temp and humidity outside will affect the inside of your sheltered, if you can stay on top of that I don't see an issue with this at all. Feel free to shoot me a holler if you ever need any help, I'd be honored to assist you. Hopefully, this was helpful, and remember ... "Happy Growing" and "Free your mind one puff at a time".

You should buy a rack for that, it works well and my advice : The rack inside the tent (check my last diary, I did pictures of my rack) but you have grown outdoor ! You can suspend them if you are in a hurry, dry and no light place.

You need between 45 and 55 % humidity mate, no light, air circulation, If your shelter is underground, it depend on isolation.
