Here when it's above about 73F, I keep stuff in my Sichuan pickle perpetual gig overnight on the counter (11pm to 7AM) , then it has to go in the fridge. This for hard veg like chayote, carrots, and maybe cabbage-- anything else and it takes even less, and will quickly veer into mushy-and-squishy. Things like cucumber pickles, forgetaboutit, I don't even try to do them outside the winter because it's impossible. Even my sourdough bread, during summer it doesn't come out of the fridge.
If it's warm where you are, seek out a cool place in your house and keep a close eye out to avoid disaster.
