Hello! I'm thinking of getting a bearded dragon in the future, however, I have no clue what to do about the substrate. I've read to not use sand or to only use play sand, to only use paper towel or ceramic tiles, to use a mix of sand and coco peat. I have no idea?! I would rather a more 'naturalistic' look. Preferably no tile, paper or carpet. Would a bio-active dirt mix of coco peat and play sand with work? I can't imagine it would retain humidity with heat lamps constantly evaporating water and I love the natural dirt look. It's organic and natural, so would impaction even be a problem?
