Hello,

As a heat source for my BP I use an UTH and an infrared heat lamp. (The latter I recently added.) What I am unsure of is the usefulness of an UTH; it is hot when directly touched (too hot, in fact), but with any kind of substrate on top, the heat seems minimal? In short, it doesn't seem like there is much heat penetrating the substrate, which I use coco-fiber for after switching from wood shavings.

Obviously I have to have substrate on top of the UTH, it just doesn't seem to transfer any heat past 1/2 inches of substrate.

Am I missing something?
