The only thing I would be concerned with your ink bird will knock of at your perfect temperature but the heat will still be in your blanket I have my ones in the garage just made a box with ply wood put some king span around the inside my fermentation bucket on a heat mat ink bird in my bucket cost a little bit but perfect jobI was wondering if anyone has used a electric blanket as a heat mat?
I've a small circler mat I use I the garage with a coat tied around the fermenter. I would like to put 2 batches on at a time and have been banished to the garage because of lack of space in the house!
