Me and my newbie questions.

[redshepherd]

Just a few more newbie questions here, before I start buying setup things... Get ready.

Is there a reason why glass tanks need a heat lamp+heat bulb+undertank heater, but a Sterilite tub setup only needs one undertank heater?

Humidity in the enclosure is provided solely by the water bowl + contained enclosure?

Using a tank setup (vs. tub) seems like a much more costly option, though both options appear to work? Is the tank setup mostly just aesthetic?

I've read that BP do not need lighting, but would they be alright in truly 90% darkness all the time, just to be sure?

Also, just curious what the reason is for covering 3 sides of the tank? (I assume for the snake to feel secure)

And finally... not a question in the right forum, but could anyone recommend reliable breeders for getting a BP online? Or any known good breeders in the Orange County/LA area?
