1) if i want my BP to grow 5', i need a 5' long tank, and that the snake will only grow as long as its terrerium length. true or false?

2) is plaster of paris safe? is spray paint safe?

3) is it ok to use real rocks in the tank?

4) does all pourous material need to be sealed? aka rocks, wood, home-made hiding places. if so what do i use....clear spray paint?

5) my BP is 21" long at the moment. does the size of the tank matter or can i put her in a 100 gal terrerium and let her grow all she'd like?

6) is there a difference between a red light you find at walmart and these "infrared heating bulbs" i find at the pet store?

Thanks for ANY help on these questions!
