I live with no AC. First thing, all windows get blocked with blackout curtains or whatever you can find. Wear loose cool clothes. I like to wear linen. At night and early morning/dusk, open the windows and doors (if applicable) to get the cool air flowing through your place. If you can, keep them open all night and seal them up once the sun comes up. Use a fan to blow directly on you. Even when it’s hot, that air flow is a life saver. Misting yourself and standing in a fan is a very effective way of keeping yourself cool. All your physical labor chores you’re going to want completed early in the day or after the sun goes down.
As for your laptop, maybe pointing a desk fan at the keyboard may help?
This also depends on the concentrate. My coworker at my old job almost got caught vaping a cartridge of live rosin bc it ended up sticking up the bathroom.
