Im building a new tub set up for my 700g female ball python which will most likely be her home for the next couple of years (unless she reaches gargantuan proportions).

I have pretty much everything ready but im not sure if silver mylar tape is okay to use to put the flexwatt im using as a heating source onto the plasic. i'm afraid it isnt going to stick. everything i've read says to use foil tape, i was also wondering about electrical tape since its super sticky (and will be OUTSIDE the enclosure only).

thoughts?

* i have a johnson thermostat, the flexwatt will be controlled with that.
