The Bio Dude's reputation was partially formed around our top-quality bioactive vivarium substrates & high quality education and science backed initiatives for proper husbandry. The Dude's bioactive substrates will last the life of the animal if maintained accurately, foster symbiotic relationships, grow plants, moss and support populations of beneficial microfauna such as springtails and isopods.  From the Terra Flora to the Terra Aranea, our  substrates are handcrafted, mixed and are high quality. Our substrate is used by ZOOs, Veterinarians,  museums, breeders, and enthusiasts all over the USA and Canada. We are proud that our substrates have changed the husbandry standards of many keepers and reinforced proper animal welfare across the USA. Not sure what substrate is best for your pet?
