Hello,
From what you have posted it seems you have just about everything. Do you have a hygrometer, to measure the humidity? Just something I noticed wasn't on your list. Just keep an eye on the temps until you get your thermostats, and keep an eye on your humidity as well. If there is a lot of open space in your tank, you might want to run to the dollar store/Walmart and get some fake plants to put in there or wad up some newspaper just to take up some room so that your new babies will feel secure in their homes. Good luck with the new babies!!! And I saw their pics on your other post....Beautiful snakes!!!!
