Episode 170: Unlocking Soil Potential: Dr. Colin Bell on Microbial Consortia, Rhizosphere Ecology, and Mammoth P
Episode 170
Wednesday, 19 August, 2026
Key Takeaways & Highlights Mammoth P Relaunch & Product Updates The Return: After stepping away in late 2022 and spending three years working with the Microbial Mass Pro team, Colin bought back and officially relaunched the Mammoth brand. ~70% Price Reduction: Streamlined, scalable manufacturing allowed Colin to drop the price by roughly 70% compared to legacy pricing, making it significantly more accessible for all growers. 3-Year Shelf Life: A subtle reformulation extends the active, non-spore liquid shelf life out to three full years. Application Rate: Continuous weekly applications at 0.6 mL per gallon throughout veg and bloom yield the best results across all substrates (living soil, hydro, coco, and rockwool). Mammoth P vs. Microbial Mass Pro Mammoth P: Uses active (motile), non-spore-forming bacteria selected directly from natural soil samples to liberate phosphorus and trace metals like iron. It is carried in an organic, alfalfa-derived liquid medium. Microbial Mass Pro: Uses dormant Bacillus endospores suspended in a clean, synthetic-like solution. While Bacillus spores require 24–48 hours to germinate once applied, active motile strains start functioning immediately upon contact with the root zone. The Power of Consortia Microbes in nature do not work in isolation. Multi-species consortia offer synergistic functionality (1+1+1+1 = 5, 6, or 7) and greater ecological adaptability across changing pH, moisture levels, and soil micro-pores than single-species products. Addressing Common Grower Myths Brewing into Compost Tea: Discouraged. Tank brewing introduces unpredictable competitive dynamics, risks losing the intended consortia balance, and isn't necessary given the product's concentration and price point. The Triacontanol Myth: Alfalfa meal is used strictly as a carbon and nitrogen source to feed the bacteria, undergoing heavy boiling and filtration to sterilize the media. Independent testing confirmed triacontanol levels were untraceable or present in negligible parts-per-billion amounts—it is not the driver of performance. Pathogen Concerns: Colin debunked rumors regarding human pathogens, explaining strain specificity (the same way safe E. coli strains differ from harmful ones) and highlighting full regulatory approval across international agricultural departments.
