Royal Soil Bioactive Blend
6 quarts (4-6 lbs) of soil per bag
Royal Soil is our flagship premium bioactive substrate blend explicitly designed for high-moisture environments and species that rely on decomposing organic matter. Ideal for detritivores, moisture-loving reptiles, and invertebrates, this carefully balanced mix supports both animal health and plant vitality within a thriving micro-ecosystem.
Crafted with a blend of peat moss, sandy loam, mushroom and redwood composts, maple and cherry wood pulp, magnolia leaves, and dried oak wood, Royal Soil offers a continuous source of rotting material essential for decomposition. To offset the high carbon content of the decaying wood and leaves, nutrient-rich worm castings are included to create a nitrogen-rich environment, enhancing soil fertility and promoting robust plant growth. This dynamic balance makes Royal Soil an ideal foundation for bioactive enclosures, supporting the clean-up crew and lush, thriving plant life.
Ingredients: Peat Moss, sandy loam, Mushroom Compost, Redwood Compost, Maple and cherry Wood Pulp, Worm Castings, Magnolia Leaves, dried Oak wood, Lacticaseibacillus casei, Rhizophagus intraradices, and a proprietary yeast blend (less than 0.01%)

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 Terry’s Topshelf Bioactive Blend provides ideal moisture retention, structure, and microbial support through a mix of peat moss, sandy loam, composts, sand, and vermiculite. For arid-dwelling species, Terry’s Arid Arachnid Blend includes calcium-bearing clay, which helps maintain substrate integrity and supports springtail populations in otherwise dry conditions. For enclosures focused on detritivores or overall decomposition, Royal Soil offers a rich blend of organic matter, composts, and wood pulp to promote a thriving biological soil 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? But don't just listen to me, go check out our reviews as well!
