Snake rack heat tape?

[Stewart_Reptiles]

Hello and thank you for letting me join the form. We just got done with building are snake rack and we were wondering what size heat tape and what wattage of heat tape we should use? The quarts are 66 quart and 32 quarts the rack is made out of melanite. Thank you in advance.

a 3 to 4 inch strip running across the back is usually the standard and more than enough when it comes to a hot spot.
