Please help me I'm so confused.

I don't know what effects the heating pad will have on the fibre, but coco fibre matting is supposed to be slow to rot. It may degrade over time though.

Thank you elly, you probably don't know how much your advice is helping (on this post and my other post).
I have now decided I am a little worried about the heat pad option. My vivarium has the exo terra compact top which houses two bulbs so I will put a heat bulb in one side and a UVB bulb in the other side. I have also bought one of the light domes which I intend to put a full spectrum bulb in for the plants. The only thing left is heating for night time so I will probably have to buy another light dome for a night heat bulb, so I THINK I am set now but there will be time to change things here and there if need be when it is set up cycling (explained to me by Dan, THANK YOU Dan).
I received my vivarium by courier on Thursday and was all excited to start slowly getting everything together and I was so dissapointed, It was smashed but thats another story.
Thank you again for the help.
