Root Biome Builder

At A Glance

Root Biome Builder is a professional-grade liquid biological inoculant designed to fortify the foundation of your plant collection. Specifically engineered for container-grown plants and high-value collector aroids, this formula introduces a concentrated dose of both Bacillus subtilis and Bacillus amyloliquefaciens.

By establishing a robust microbial colony in the rhizosphere, it bridges the gap between sterile potting mixes and the complex ecosystems found in nature. Whether you are acclimating a rare import or maintaining a prized Monstera, this soil drench application supports the biological diversity necessary for superior root resilience and nutrient availability.

  • Formulation: Highly concentrated liquid beneficial soil bacteria.

  • Active Ingredients: Contains Bacillus subtilis and Bacillus amyloliquefaciens

  • Application: Simple soil drench designed for container-grown plants.

  • Key Benefit: Directly supports and diversifies root zone biology.
What It Supports

Root Biome Builder introduces beneficial Bacillus species into the rhizosphere—the active zone surrounding plant roots.

  • Microbial Diversity: Enhances the biological profile of container soil and soilless media.
  • Nutrient Availability: Supports the breakdown and availability of nutrients in the root zone.
  • Biological Balance: Promotes balanced biological activity for a stable growing environment.
  • Root System Resilience: Strengthens the plant's natural foundation against stressors.
  • Note: This product is not a pesticide and does not directly kill pathogens.
How to Use
  • Preparation: Shake gently before use.
  • Mixing: Dilute 4–8 mL per gallon of water (1–2 mL per liter).
  • Application: Apply as a soil drench until the medium is evenly saturated.
  • Frequency: Reapply every 3–4 weeks during active growth, or immediately after repotting.
  • Compatibility: Do not mix with strong disinfectants or bactericidal products, as these may harm the live bacteria.

FAQ

What is your Live Delivery Guarantee?

We guarantee that our Trichoderma T-22 arrives with a 100% viable spore count. Because you cannot see these organisms with the naked eye, our guarantee for this product is handled differently than our predatory mite or nematode guarantees.

  • Viability Guarantee: We ensure that the product has been stored in climate-controlled conditions and shipped in UV-protected packaging to maintain peak potency. We guarantee the spores are "active" and ready to colonize your roots the moment they are hydrated.
  • The "Proof of Life" Period: Unlike mites (which you check on day one), the proof of Trichoderma is seen in the plant's response. We offer a 21-day viability window. If you apply the product as directed and do not see an improvement in root health (whiter roots, increased root mass) or plant vigor within three weeks, contact us.
  • Shipping Protection: If your package arrives punctured, wet, or has been exposed to extreme heat (left in a mailbox over 100°F) and the powder is clumped or discolored, take a photo and contact us within 24 hours. We will replace the product to ensure you are starting with a healthy colony.
Can I use Root Biome Builder in semi-hydroponics (LECA or Pon)?

Yes. While designed for soil-based containers, the Bacillus strains in Root Biome Builder are highly effective in inorganic media like LECA or Pon. They help break down organic debris (like old root sheaths) and maintain a clean, biologically active reservoir.
Will this product cause a biofilm or "slime" in my self-watering pots?

When used at the recommended dilution, Root Biome Builder promotes a healthy microbial balance. However, because it contains live cultures, we recommend rinsing your reservoirs every 4–6 weeks to prevent any natural organic buildup, especially if using organic-based fertilizers alongside it.
Is Root Biome Builder safe for propagation and "rehab" plants?

Absolutely. In fact, it is highly recommended for props. Introducing beneficial bacteria early in the rooting process—whether in moss, perlite, or water—helps establish a protective "biome" around emerging root initials, making the transition to a permanent potting mix much smoother.
Can I use this alongside my regular liquid fertilizers?

Yes, it is compatible with most synthetic and organic fertilizers. For the best results, mix your nutrients first and add Root Biome Builder last. Avoid mixing it with concentrated "flush" products or high-strength peroxide treatments, as these are designed to sterilize the environment.
How soon will I see results in my aroids?

While the bacteria begin colonizing the roots immediately, visible results (such as increased vigor or larger leaf pushes) are typically seen after 2–3 applications. The goal is to build long-term "rhizosphere resilience" rather than a temporary chemical spike.
Does this product have a strong odor?

Root Biome Builder is a clean, liquid formulation with a very mild, earthy scent that is virtually unnoticeable once diluted. Unlike some fish-based or heavy organic fertilizers, it is perfectly suited for use on indoor shelving and in living spaces.

Mite Matters

Native vs Invasive Ladybugs

Native vs Invasive Ladybugs

— Karen Horn

Most ladybugs you'll encounter are red with black dots — and that description fits native, introduced, and invasive species equally. Here's how to actually tell them apart, what the harlequin ladybug has been doing to native populations, and where the real ecological concerns are.

Your Grow Light Isn't Killing Your Predatory Mites. Your Humidity Might Be.

— Karen Horn

UV gets all the attention, but it's rarely the problem under standard LEDs. The variables that actually determine whether predatory mites thrive in a lit grow space are humidity, heat, and photoperiod — and all three are fixable once you know what to look for.

Predatory Mites Outdoors

Predatory Mites Outdoors

— Karen Horn

Predatory mites have been managing pest populations in orchards and gardens for decades — the outdoor track record is solid. The approach is just different than indoor. Here's which species handle real outdoor conditions, when to release for the season, and why suppression is the goal that actually keeps your plants healthy.
