Temps for compost tea

I am about to start feeding tea to my crops and it has gotten really cold since last run. I used to brew teas in the garage with temps at least 70-80 degrees throughout the night. Now its 25-40 each night and I am wondering how I should go about brewing the teas. I have a heating mat under my tent right now, do you guys think brewing it inside the tent is okay?

Brewing inside the tent is fine, just watch your humidity.

I sit mine in a bathroom/bathtub that already gets a bit too warm (small, wide open vent/register). Warmest part of the house and the tub helps deal with any spills/overflow... If you really had to, you could even use an aquarium heater to raise temps a tad I'd imagine.

Thanks guys. Im gonna brew in the tent for now until space runs out, the tub idea is great tho, l could leave it in there overnight with the vent on and no one would fuck with it.
