Yeah, I read that once on the internet too.

My experience differs from the masses.
The internet is a funny place. Back in the day we used to advise people to use indoor/outdoor carpet in snake enclosures. The stuff dries in 5 minutes and you can wash it in the clothes washer if you want. Perfect stuff. Now eveyone tells you you should use any number of substrates, and arguess about how one kind is better than the other. Since I switched to Reptibark/pine shavings/etc, I had to pull a dozen pieces of bark out of my snakes mouths over the years. Should have stuck with carpet.

Don't use hot rocks...for some mystical reason.
Don't use heat lamps...for some mystical reason.
Don't use glass tanks...for some mystical reason.
Well heat rocks heat up to burn level temps and usually concentate dangerous heat in middle of rock.
Heat lamps outside of the enclosure I like as long as enough room to move in and out of heat.
Glass tanks I like
and turtles I like lol
