This is my first post on here other than for my intro.
I have been reading quite a lot about how to set up for Royals. My question though is how good a heat gradient can you achive in a lets say 9 or 12ltr RUB. I keep tortoises and can achieve really good heat gradients on the indoor enclosures. I achieve this because the enclosure is fully open so the heat source provideds a hot spot at one end but quickly drops off as you move along the length of the table top enclosure. With the snakes enclosure being closed and relatively small I was wondering what kind of temperature gradient you can get with a heat mat.
A heat mat will only heat the surfaces it touches, not the air. Having a heat mat (with a stat) covering half of the floor of a small RUB will not affect the temperature on the other half.
Thanks for the replies, makes sense, I think where i was struggling was I tend to think of the temperature gradients in terms of air temperature as opposed to surface temperatures.
