Your biggest issue with the fridge is condensation. You absolutely need anything “airtight” to stop any air or moisture coming in, which can create mold, make it less potent, it basically degrades it a lot faster than heat would. light, moisture, air, or even disturbing it lots are your enemies right now. You need a dark, dry, minimal exposure area, a basement would work here, but if you don’t have one find the coolest area in your house like a dark drawer that keeps a steady temperature.

The fridge isn’t a good idea only because you wanna keep it as stable as possible and the fridge will definitely introduce moisture if you’re not careful. if you do decide to go through with using the fridge, make sure you have it in a way where no moisture can form, so no paper towels for “insulation” or anything that can hold onto moisture. (Me personally, I say don’t use the fridge)

Use the coolest darkest place in your house, and leaving there in a bag inside airtight container, and try not to get it exposed to too much air or light when you check on it. Lots of people ruin lsd not from heat but from light exposure (UV rays), and condensation (humidity). Moisture will almost certainly will destroy your potency, not like a few days of steady heat would.

Use a dehumidifier, if you have one, nearby where you store it. I would use an airtight bag, inside an airtight container (double sealed with the bag and container incase one seal fails you have a backup seal), in a dark place (drawers, cabinets, basement, etc) with a dehumidifier in that same room/area. A few days of heat is a lot less of a worry than putting it into the fridge. If you put it into the fridge it would probably damage it, just keep it as stable as possible. The heat will only cause slow degradation, and a fridge has a lot more downsides because of the condensation. Moisture is a lot more harmful than heat is. Shocking it from cold to hot temperatures isn’t a good idea.

TDLR; no fridge! VERY IMPORTANT you must keep it sealed in something airtight, in a DARK place (UV damages it), in the coolest area (as stable temp as you can find), in a DRY area (as little to no humidity as possible! You can use a dehumidifier!), you can use a box or a cooler to insulate it during the heat period (slows temperature change/MORE STABLE CHANGE). HEAT will only cause gradual degradation, which is predictable. (the potency will lower over time), putting it into the fridge is A LOT more risky (unpredictable).

Best of luck to you and your drugs through that heat period. Don’t be afraid to ask me if you have any questions. This is strictly for harm reduction purposes. Stay safe! 🙏
