Wondering if anyone has any good tips on keeping a small room or closet cold when growing mushrooms. I live in an old place and we have no AC only heat.

I live in CA and the temp gets up in the high 80s all of the time, and my grow closet gets up to high 70s almost. Now that summer is right around the corner I’m getting worried about the rising temps.

I don’t have space or budget for an AC unit, but don’t want to lose everything in a hot summer day.

Any recommendations to keep the room cold? Lately I’ve been putting a big bowl of ice in there, but it’s a pain and doesn’t work that well.
