Ok so I'm so tired of tanks and heat lamps, they are just making everything worse for my BPs since it's just so dry here. So, I need help on my shopping list.

Ok here's the list, not really sure how much everything will cost, but oh well:

1- 10-20g UTH ($21 each)
2- 2 dimmers ($21 each)
3- 2 AccuRite ($15? each)
4- Soldering Iron (er...$$?)
5- tell me anything else I may need.

Here are the questions I have:

1- What size tub would I need for a BP who is around 1.5 feet long?
2- What size tub would I need for a BP who is about 3 feet long?
3- Can I just peel off the 10-20g UTH off of my 20g tank or would I need to do something to peel it off?
4- If the UTH can't stick back onto a tub, what could I use to make it stick again?
5- With a dimmer, could the UTH not melt the tub?
6- What are the best places to buy the tubs and AccuRites?
7- Could I use anything else besides a soldering iron to put holes in the tubs?
8- How much would everything pretty much cost me just so I know how much money I should be making to acquire this stuff ($93 estimated for the stuff besides soldering iron, but how much would the iron cost)?

If you could please add anything to my list that would be appreciated, as well as answer those questions I have.

I already have 2 hides for both of the BPs including a water dish and some plants. If I already have a digital thermometer, what should I get for the hygrometer? I am not sticking back to those pointless analog ones.
