I've got a whole room dedicated on the first floor of my house for only qts. No room temp house is ever going to be warm enough without extra heat. So I use tubs and uth's and thermos for any balls that are in qt. Easy clean easy to heat. My qt room doesn't have any other herps in it so it doesn't stay as warm as the other rooms. It's probably around 65 we try and keep our heat down bc oil is outrageous. But that just means all have 24 hr heat. Hence why I like uth's and heat cord.
