In Rhode Island. My part is getting the 30". I would get a space heater or propane heater but I still have to work 9 am - 9 pm everyday snow or no snow. So I will not be home and probably will not leave it on for safety reasons. I only have one snake, should I put the hand warmers directly in the tank in a sock or tape them to the bottom of the glass? I am going to look for 24-40 hour heat packs tomorrow before work. I am not looking forward to this. When i used to have multiple snakes when I lived home I would put their tubs about 5 feet from the fireplace. Now living in a apartment I am out of luck I guess lol. How hardy is a BP and will these hand warmers prevent a possible RI even if the ambient temp is still cold?
