I am doing my first cold weather smoke. Started with lump charcoal had the vent opened most of the way. Dumped the lit coals in the basket. Then went inside to prep the bird. The cook chamber was about 210* when the turkey and beans went in. I then added some hickory chucks and oak mini splits. The cook chamber is covered with a Harbor Freight fire blanket, that is folded in half. Fifteen minutes later I go out and check and I'm pushing 330*. So I just closed down the vent.
Was afraid that I would not be able to get the cook chamber hot. I guess that is not the case and I can finish it outside. I was thinking a couple hours of smoke then finishing it inside. But now I am going to let it ride and see how my first turkey does.
