A man after my own tastes, news paper or butcher paper makes a cheap wonderful cage substrata. Cheap, non-toxic, no chance of impaction, and easy to use. If you don't like the daily news in you cage, try going to an art or grocery supply store and buying white butcher paper, brown wrapping paper or unprinted newsprint paper. I don't like that they hide under to paper so I use two sided tape to hold it down. It becomes a little harder to clean up but you live with it.
I don't recommend this for burrowing species. Give them a better substrata. Here begins the controversy! I am not going to tout one produce over another but I lean toward the easy and cheap. Coco fiber - the current prima dona of the substrata crowd is expensive and has been know to cauese impactions and ocular problems in some reptiles. Vermiculite has pro and oponents as well. I prefer vervicullite because I can control the humidity of the cage with it. Misting will remove the dust problem. Alfalfa is a good choice because it is edible if swallowed. But mold can be a problem and worse a powder mildew sometimes develops in moist climates. Tipsoil can be used if screened but it is messy save for the burrowers or naturalistic setings. Bark mulch - cheap but another dangerous produce. Not only from the posibility of impactions but from the danger to the eyes. Soft wood bark(pine, cedar, and redwood) mulch tend to give off toxic chemicals that can affect the liver. Lots of dust associated with the material. Sand and pea gravel can cause impactions but are cheap, easily obtained, and can be washed and reused. They are heavy and increase the weight of the cage a great deal.
I am almost to the point of following the zoos and using a foam material that is shaped, then placed into the cage complete with hides and holes for potted plants and water bowls. It can be painted and made to look like rock or soil.
Good luck and know there is no wrong answer merely choices. You must decied what is best for you! Weigh the factors, experiment a little then make the jump! If you don't like it change it!
Good herping!
