Hello All, I'm new to the chameleon world and the forums. I'm putting together a screen cage setup and want to use live plants. Bought some plants at Lowes, Yucca cane and Draecena. I know I need to re-pot and wash etc. I looked at potting soil, but every bag contained perlite. Is perlite the styrafoam pellets? What kind of soil is safe to use? Thanks very much
