Hello, and welcome! I'm only a week or so ahead of you and so am still finding my way around tank set-up.

This board pointed me in the direction of the Acu-Rite with the long probe, $12 at WalMart (hardware/lighting section, not gardening). It accurately measures both high and low temp AND humidity level, yet is the same price as the thermometer/hygrometer packs sold at Petco and PetSmart. The Petco hygrometer that came with our tank is about 20% to 30% off!

I read Zilla's description for that particular kit, and it says the 2 dome lights provide the proper amount of light and heat. Perhaps so, for snakes that need warm air. But since BPs need belly heat and hide all the time anyway, they need that under tank heating pad. Our snake's prior owner didn't have a UTH, just one lamp, and the poor guy was cold first time I saw it.

Apparently, a UTH shouldn't be used without something to control its heat output, and the gadget recommended here is the ReptiTemp 500R. Our local pet stores don't carry it, so I ordered one from Amazon and it only just came in this morning's mail. After a week of worrying that our new snake would burn, this thing will be worth its weight in gold, LOL!

So, where are you getting your BP from? I got mine via a CraigsList ad. I see Petco has them for only $30 this week, too. Is this your first snake ever? A hard thing for us is getting used to looking at an empty tank, since BPs hide all the time, and holding it only a tiny fraction as much as we'd like. Pre- and post-feeding hands off encompasses 3 or 4 days right there. Ack!

Enjoy your new BP. This forum is an absolute wealth of info, and the Search function (especially Advanced) is very good too.
