Coco Fiber Liner

[UwabamiReptiles]

I plan on building some cages for some of my red tailed green rats when they get bigger. My question is, does anybody have any experience with coco fiber liner? Its the stuff you see in hanging plants sometimes. I found that you can buy the stuff in a roll and thought it would be good for the sides and back of the inside of the cage.

I've seen some pics of cages on line with the coco fiber in them. I have no idea how well it would hold up to humidity and stuff though. Would it just be a place for bacteria and mold to grow? I really like the idea of it, I would assume that with proper ventilation and no stagnant conditions it would be fine. Does anyone have any hands on experience with the stuff?
