brrr!

It's too cold up here in the great northwest! It's dropping into the 30's at night and my cider isn't doing anything. I pitched my yeast 3 days ago and I haven't seen anything happen. The juice is clear as can be and everything has just settled. I'm sure that due to the temperature, the yeast has just one dormant.

I've heard about some electric belts you can wrap around your buckets/bottles. Do they work? What am I looking at for a price range on them?

Thanks folks.

I was gonna get one but read no for use with glass carboys. Buckets or Better bottles OK.
