Hi everyone, I know there is a lot on this forum about heating enclosures but I was hoping for a bit of advice. I have a sub-adult Stimsons python that I am hoping to give a full size enclosure soon. Up until now I have just used a 15W heat cord under its click clack at one end. I have read that in a vivarium you can either use the heating lamp or the mat/cord. What I don't really understand is how you position a cord or mat. If it goes under the wooden base of the vivarium, I would assume that not much heat would transfer through to inside. I might be wrong though! Any advice would be really appreciated. Also, if you think the lamp is the best option please could you recommend me which would be best. Thanks!
