Bud drying

Hey guys

It's my second season as a grower and last year i had no problems drying my buds, as i had a place to do it perfectly. But this year i have no place to do it. BTW i am an outdoor guerilla grower
So i was thinking of constructing a box, with several horizontal lines, where i would hang my buds to dry. The box would be wodden, with styrofoam in the walls and it would be isolated from watter. There would also be a hole for a small fan in the upper side and a small hole in the bottom side for air circulation (the holes would be in opposite sides). The holes would deffinetly have a mesh so that the bugs could not get inside.
What do you guys think?

I am scared about mold, so i would really like to hear your feedback

Do you have a car? You would be better leaving said box in a vehicle than out to the elements. All it would take is a good hot rain to jump that rh too high and at least you would have some protection in your ride. Good luck with whatever!

Well i need my car and i cant drive around with that :/
I would hang the box in a tree in the middle of if...

leaving outside sounds a bit scary to me.. as stated above, rain, morning dew.. what is regular RH outside in your area?

Well when i will need to dry my buds it will be quite rainy, that is why i am asking you guys for help, cuz im low on ideas...

It doesn't have to be a running car.
I can't come up with any good ideas,how 'bout renting a storage spot?

yeah but e.g. in a place where I live on a rainy week I get 55-60% RH but in other places RH is 95% even on sunny days.. it's a tough task to dry them properly outside especially on a rainy season..

any neighbours around with a woodshed or somth? ofc you can use a heater, but a waste of money on electricity..
