Hello everyone. I just ordered my Beardie a new Custom Repile Habitats Evo 2.0 4x2x2 PVC. He's currently in a 36x22x22 wood custom build that I did a few years back. I've been using the Jurassic Natural Australian Desert sand as a substrate with no issues over the last 3 years. I am planning on using the substrate again as I still have a few bags but was going to mix it with other substrates. Either top soil, reptisoil or eco earth and excavator clay. Would this help it hold burrows and shape better than just the dry substrate? He likes to dig and it keeps his nails from being insanely sharp
