I purchased a Coleman extrema 5 on sale at Walmart for 30$ I then purchased weather stripping meant to seal doors windows etc. And lined the openings of the box. After doing so I put a bright light in and closed it to see where the light was coming out and seal those spots specifically. After that I placed baking soda inside to absorb any odors. Then purchased a lb of HF 65% beads. Which is overkill I know. And seasoned my many boxes with distilled water before placing them in. I recently calibrated my hygrometer and it accurate but I've never gotten lower than 66% or higher than 69% but my temp was consistently at 72 degrees. So I placed my cooler in front of the ac vent here at the barracks and its about 61 degrees consistently. Seeing as how you don't have ac I can see how ice packs might work or perhaps a mini blower of some sort. I have extra stripping if your interested its helped keep my cooly a lot more consistent.
