I assume you would want to use the tape to help spread the heat, as the routed channels will hold the cord in place. I think you’ll find that a tile does a good enough job and addition of aluminium tape will make little to no difference. That aside, you can drill holes in the tile and screw it to the base so it cannot be moved by the snake. That way it can easily be removed if you want to, rather than using something silicon to hold it in place.Now i know people are saying dont put tape in the actual enclosure because the snake can get stuck on it (something i didnt think about but now can see why its such a bad idea)
if i were to router channels in the bottom of the enclosure am i able to use blue tongues technique and cover the channels and tape with a ceramic tile then placing the substrate on top of that?
also is it possible to run an extra long heat cord into multiple enclosures or is it best to have one cord per enclosure?
