I recently built a wooden enclosure for my two BP's. Its significantly larger than the enclosure they are in right nowbut they r always slithering around like they are mad or sad that they have no space to roam or explore! So I built them the LAST enclosure they will ever need! It is exactly 4ft long by 2ft wide and 2ft high. I am thinking I will order some flexwatt heat tape, the largest I have seen is 11". But how much of the bottom floor should I cover with the tape and should I put something on top of the flexwatt other than the substrate to prevent burning the snakes (I will have the flexwatt plugged into my thermostat.)? Here are some pics of the enclosure:

Acrylic is used as see thru glass for top and front






Just to help you see the size in comparison to something you may know the size of off hand, that is a ten gallon tank on top of the enclosure........

So what do u think is the best heating elements to use, any advice is welcomed! Thanks

Here is one of my BP's!
