Hello Everybody. I have never used flexwatt heat tape before. I am setting up a new enclosure for when I go to repticon, gonna get a new addition

. Any way I have some questions about it.
1.) Can I put flexwatt directly on a sterlight container?
2.) Is it good to use on just 1 or 2 enclosures without a rack?
3.) Should I order a thermostat or a dimmer?
4.) What size should I get?
5.) Will this work good for keeping ambient temps?
6.) Should I run it along the side, top, or bottom of enclosure?
Thank you in advance, sorry for so many questions but I wana get this right lol.
PS.
I want a boa, one that is known for climbing around the cage and not hiding all the time like my ball. Are there an like this?
