Heating Equipment for sours???

[DrKennethNoisewater]

So, this might seem like a really basic question, but I've yet to make any sour beer, so what the hell...

Based on all the stuff I'm reading, it sounds like an essential component to making quick sours (Berliners, Gose's, etc) is to keep the wort at a high temp (90 degrees or so) for the first 24-48 hours once your Lacto culture is pitched.

My question is this:

What do you use to keep your fermenter warm? A heating pad, blankets, what? What's the best, most effective method?

Any help is greatly appreciated.

A brew belt works well.

A heating blanket attached to a temperature controller.

A light bulb inside a paint can, inside your fermentation chamber, attached to a temp controller.

My bedroom during the summer months.

For my first sour, I chilled the wort to 110F, pitched my culture, then put my large down jacket around the fermenter. It actually held temp really well.
