Aside from food, the substrates in our pets’ cages are the most important element in setting our pets up for a healthy existence. Substrate is the ground covering for our pets’ tanks. It isn’t just dirt. Some bugs live in it, some eat it and it is the primary source of tank humidity for them all. I’ve raised every group of pet bugs in this hobby and we tailor-blend each substrate product we offer specifically to support the animals that we sell. It’s easy to stand by these products because we use them in all our tanks.
