Im attempting my first sour brew soon and looking for some advice. Using a kettle sorring method and WLP672, and was planning on dropping down to 3.5 Ph. Unfortunately the ambient temperature of our brew space can get to near freezing. We have an inkbird and a heat mat but, seems they arent able to keep the wort at 40°C. Any tips to keep our critters nice and snug?

I have a insulation layer (the bubble wrap foil stuff, thermawrap I think) which I wrap my boiler in when mashing (BIAB).  For kettle souring I whack a sleeping bag over the top too.  It doesn't hold 40, but it sours fine over 48 hours.
