3 quarts (4-4.5 lbs) of soil in a 8 x 12 1⁄2 x 4.25” resealable bag.

Royal Soil: Sonora is our reimagining of the Sonoran desert as a premium bioactive substrate blend explicitly designed for arid environments and species that thrive in dry, low-humidity conditions, but still need a substrate that won't collapse on them and won't become a dusty nightmare. This carefully balanced mix supports animal health and plant vitality within a thriving micro-ecosystem.

Royal Soil is an ideal substrate for:

  • Aphonopelma, Brachypelma, Harpactira or Pterinochilus genera.

  • Arid reptiles that thrive in clay substrates

  • Desert arachnids and other invertebrates that thrive in the harshest places on earth

Crafted with a blend of calcium bearing clay, sandy loam, mushroom and redwood composts, maple, oak, hickory and cherry wood pulp ground coarsely, sand and supplemented calcium to reduce the acidity of breaking down of organic materials, Royal Soil: Sonora mimics the alkaline nature of a thriving desert. This dynamic balance makes Royal Soil: Sonora a strong foundation for bioactive enclosures, supporting the clean-up crew and lush, thriving succulent plant life.

Ingredients: Sandy loam, Redwood Compost, Mushroom Compost, Sand, Coarse Ground Hardwoods (Oak, Hickory, Maple, and Cherry), Calcium Bentonite Clay, Calcium Carbonate (Supplemental), and Rhizophagus intraradices.

Getting Started with Bioactive?

Creating a bioactive enclosure is an excellent way to provide your reptile or arthropod with a naturalistic, self-sustaining habitat. By mimicking natural ecosystems, bioactive setups utilize living organisms to help manage waste, support plant growth and maintain overall enclosure health. For beginners, setting up a successful bioactive enclosure starts with choosing the right substrate tailored to the species’ environmental needs.

For moisture-dependent species such as many tarantulas and invertebrates, a substrate like Royal Soil provides ideal moisture retention, structure, and microbial support through its rich blend of organic matter, composts, and wood pulp. This substrate excels in tropical and temperate bioactive enclosures where decomposition and a thriving cleanup crew are essential to maintaining a healthy environment.

What makes Royal Soil the best bioactive substrate for exotic pets?

When we created our bioactive substrate, we would often get asked a simple question that would ultimately have a much more complex answer: Why would I spend $17 a bag of your substrate over the same price for 25 quarts of the 'other guy" To which I would respond back: You don't buy a lamborgini and put walmart tires on it, and you wouldn't put A1 steak sauce on Waygu steak, so why are you putting cheap crap substrate in with your precious new baby you spent a fortune on?
