So I started working on my wardrobe box for drying and testing out RH/temp.
First off, is this what you were describing? I know you mentioned making C cuts, I have one on each side of the box.
My other follow up, how many bottles of frozen water do you place inside?
I tested with just a 1 liter frozen bottle, dropped the temp at the bottom of the box by 5°, down to 70, but the top of the box was still in the 75° range.
Should I just add more bottles, or do you think 75° with an appropriate RH is manageable?
