hey i just put together my new cage and i used the coconut bark and i wouldnt suggest it. It gets really nasty after a week or 2 with all the misting/dripping etc. and i'm pretty sure if it was left a little longer it would have molded soon. I would suggest getting a repti cage carpet(i got mine at a local petstore) but i'm sure anything would work at the bottom. The cage carpet fits in and looks nice and you can soak it in water ring it out and throw it in the dryer and reuse it.
Also I use a hibiscus and some pothos(both bought from home depot) and then got some fake vines from the walmart fake plant area. We washed everything and repotted the plants in an organic soil and he loves it

I may be having to get a new hibiscus because he eats it all the time.
