Misc Instapot for fermenting indigo?

[Faroe]

Every summer, I mean to start another indigo vat, but I never get around to it, and it is always winter when I'm thinking of fiber.

I don't need a big vat. My old one was a 1/2 gallon canning jar with an airlock. Crock pots don't get low temp enough. Yogurt temps are about what is needed. I can make a makeshift one with a cheap thermostat, a reptile heat mat, styrofoam cooler, and a large glass jar, but the set up is a little clumsy.

Anyone here who thinks the Instapot (or something else) might work? I recall several members posting about them around Christmas. No, I wouldn't later use it for food.

I use a five gallon bucket with a higher quality fish tank heater, or you could use a stock tank heater. I wouldn't use the IP for this project.

Ok, thanks, Packy.
Those are easy enough to find, even in the equivalent of a nano tank size - they are popular with betta keepers. Never used one, since gold fish don't need heat (always did want a betta, though). What temp do you set it at? 85F? 90F?

Thanks.
