Trying to figure out if my garage is gonna ruin my leftover stash before Labor Day. It hits like 90+ degrees in there most afternoons and I don’t have a basement. I got them off the concrete floor on some pallets but still worried tbh. Anyone had issues with cakes or shells going bad from heat alone? Not talking about humidity (got a dehumidifier running) 鈥?more like does the powder composition actually break down at those temps? Kinda paranoid after seeing how hard it is to restock right now lol.
I store my stuff in a detached garage in Texas so trust me I feel your pain. Been doing it for years and honestly the heat alone isn’t a huge problem for 1.4G consumer stuff as long as they’re dry. The bigger killer is temperature swings 鈥?when it cycles hot/cold/hot the cardboard can absorb moisture and then you got issues. Pallet + dehumidifier is smart. I also throw a cheap thermometer/hygrometer in there just to keep an eye on things. If humidity stays under 60% you’re probably fine.
chiming in late but yeah what Ron said 鈥?humidity is the real enemy not heat. I left a box of roman candles in my shed one summer and the humidity got to them, half of them just fizzled out. Since then I keep everything in plastic tubs with silica gel packets inside and it’s been fine. Those rechargeable dehumidifier bags on amazon work great too, just microwave them every few weeks to reset.
Late to this but wanted to add — if your garage has a concrete floor, don’t put the boxes directly on the concrete even if it feels dry. Concrete wicks moisture like crazy especially in summer when the temp difference makes condensation. Put em on a wooden pallet or at least some 2x4s underneath.
Learned that one the hard way a few years back. Lost half a case of canister shells to damp cardboard.
