hello everyone! I need some help in finding EXACTLY what i need to have for a BP. Ive been reading like crazy the past week and i read something different, or something that contridicts something else ive read. Money is not a problem in setting up a terraium. Do i need to have lights? Some told me yes and other say the light through the window is more than enough. How many UTH's do i need? im buying a 20gal long today to start out in. Move up from there. Do the UTHs keep the heat and humidity well, without the need for a CHE? Any help would be greatly appreciated. This was supposed to be a gift for my sister, but Im getting one myself in the process!

Thx a million!
