hi guys, I've just built a viv for my 4yo murray darling python, which is 1200 x 1200 x 600, but I'm just after some advice, should I install a heat lamp or use a heat mat for him, I know they don't require uv lighting either so does this mean I can just use a normal light bulb, also I was wondering on a substrate.... can I use bark or leaf litter or soil or should I just use breeders choice cat litter like most everyone else? also can i grow plants in the enclosure with him? just wondering what everyone else does and what is ok for them and what isn't, just trying to keep his environment as natural as possible, any information or ideas would be helpful
