before I ask I want to say im really sorry if this is said somewhere but I couldn't find it if it is just post a link please.

ok to give you a general idea of what im wanting to heat I am planning on building a rack out of melamine wood (is that good???) it will be 4 shelves 3 tubs to a shelf (or maybe 3 shelves 4 tubs to a shelf whatever is easier to heat) the sides and back will be completely closed in the ventilation will be from hole in the tubs.... and the room for now I will not be able to heat with oil filled heater..... with all that being said my questions are:

1. what is the safest heat tape,matt etc. keep in mind I do have a electrical background lol

2. what type of t-stat is best to use with something like this im hoping to only have one t-stat to power the whole thing (if possible)

3. do I put the heat tape under the tub or attached to the back? Iv seen some talk about it on here but im still kinda wandering what would be best for the snake itself.

thank you in advance
