Substrates?

So recently i have been experimenting with bedding lately with my Snakes, I've tried aspen, carpet, forest bark, And now I'm trying "coconut husk" I'm liking the husk more then the rest seems too keep humidity very well and looks very natural. I'm wondering what your thoughts are on coconut husk? good or bad experiences?

I love the coconut husk. I use eco earth and it lasts a long time and works very well. My adult snake is able to easily dig trenches in the eco earth too which seems to keep him comfortable. And since I'm using a glass tank it holds humidity very well. However for my hatchling I use aspen.

Coconut husk is great because it does help with humidity, I also mix it with eco earth.
