    Episode 155: Entomopathogenic Fungi Explained: Blastospores, Beauveria, and Smarter IPM with Julie Graesch

    Guest: Julie Graesch Biological Scientist | IPM Specialist Currently with BioWorks Formerly: BASF, Becker Underwood, Iowa State University Topics Covered:What “entomopathogenic fungi” actually means How fungi like Beauveria and Metarhizium infect insect pests Differences between blastospores and conidia Why formulation and environmental conditions matter Common reasons fungal biocontrol applications fail Preventative vs. reactive use of entomopathogenic fungi Integrating fungal biologicals into a broader IPM strategy Key Takeaways:Entomopathogenic fungi are biological tools, not chemical knockdowns Understanding fungal life cycles improves consistency and outcomes Blastospores behave differently than traditional spore formulations Successful IPM relies on timing, environment, and integration—not rescue sprays Hosted by Simplecast, an AdsWizz company.

    Episode 154: Is Seed Based Cultivation the Future of Cannabis? - with Dr. Matthew Indest

    n this conversation with plant scientist and commercial cultivation strategist Dr. Matthew Indest, we explore the emerging frontier of seed-based cannabis production and what it would take for the industry to move beyond clonal propagation. We cover: The agronomic upside of seed-grown plants (disease resistance, vigor, adaptability, cost savings) The scientific and operational barriers preventing widespread seed adoption How genetic stability, inbreeding depression, and trait selection differ between cannabis and traditional crops Data-driven cultivation strategies for evaluating new seed lines Whether seed-based production can truly rival clonal systems for consistency and top-tier flower quality What the next decade of cannabis breeding and cultivation might look like About Dr. Indest: Matthew holds a Ph.D. in plant science and has spent more than a decade bridging academic research with applied cannabis production. He has led breeding and cultivation programs across indoor, greenhouse, and outdoor operations and focuses on developing high-performing cultivars and integrated, data-backed production systems.

  3. Episode 153: Rethinking the Basics: pH, Water, Light & Nutrients with Bryant Mason

    Episode 153: Rethinking the Basics: pH, Water, Light & Nutrients with Bryant Mason

    This wide-ranging conversation with Bryant Mason covers a series of essential—but frequently misunderstood—topics in organic cultivation. We explore why simple, low-tech data collection strategies often outperform high-tech systems and how to interpret those readings in the real world. From there, we break down how pH truly behaves in biologically active soils, what your water test results do and don’t tell you, and how water chemistry shapes nutrient availability. We also discuss practical considerations for under-canopy lighting, when it helps and when it’s a distraction, and dig into the recurring challenges Bryant sees around phosphorus and nitrogen management in living soil. Throughout the episode we jump between concepts, case studies, and troubleshooting insights that growers can apply immediately. Topics Covered: Low-tech monitoring and data-collection approaches pH dynamics in organic systems Water testing and interpreting results Under-canopy lighting: pros, cons, and real-world use Phosphorus and nitrogen management in living soil Practical troubleshooting and decision-making strategies Hosted by Simplecast, an AdsWizz company.

  4. Episode 152: Light, Spectrum, and Plant Signals — A Practical Guide with Dr. David Hawley part 2

    Episode 152: Light, Spectrum, and Plant Signals — A Practical Guide with Dr. David Hawley part 2

    In this conversation, Tad and Dr. David Hawley (Chief Science Officer at Fluence) unpack what really matters when dialing in your lighting strategy for cannabis and other high-value crops. They get deep into how plants perceive light, what “good spectrum” actually means, and how to think about intensity, uniformity, and plant response in a more scientific (and practical) way. Topics covered include: Understanding Daily Light Integral (DLI) and how it relates to plant metabolism When to use far-red and what to expect from it The truth about UV lighting and secondary metabolite production Managing leaf temperature and avoiding hidden stress from high PPFD How fixture placement and uniformity impact yield and morphology Using dimming strategies through different growth stages Why overemphasizing spectrum specs can distract from the real gains Practical steps for mapping your grow and verifying performance David also shares insights on under-canopy lighting, canopy architecture, and the future of horticultural light design, offering takeaways for both commercial cultivators and serious home growers.

    Episode 150: Plants Under Pressure: How Stress Shapes Secondary Metabolites (w/ Dr. José Leme)

    Can stress actually improve flower quality? In this episode, I sit down with Dr. José Leme to dive into the science of plant stimuli and how growers can apply it in practice. We cover: 🌿 Mechanical cues — how super cropping and vibration trigger plant defense pathways. 💧 Water restriction — why moderate, timed drought can shift carbon toward secondary metabolites like terpenes and cannabinoids. 🧪 Jasmonates (MeJA) — when they increase trichome density, and what trade-offs you need to consider. 🔬 Trichome measurement pitfalls — why bracts are the gold standard for consistent data. 🌱 Propagation & trial design — the importance of clonal fidelity and standardized protocols when testing stress strategies. Dr. Leme and I also highlight practical guardrails for growers: cultivar differences, timing, and the “sweet spot” between beneficial stress and damaging stress. 📄 Referenced Studies: Water Deficit Stress and Secondary Metabolites Jasmonates in Growth, Trichomes, and Cannabinoids Metabolic Responses to Water Deficit Trichome Sampling & Quantification Methods Trigonelline as a Biomarker for Drought Stress (Preprint) Propagation & Clonal Fidelity in Cannabis Research Additional vibration study discussed in the episode. 🎧 Whether you’re a grower, consultant, or researcher, this conversation will give you a framework for using stress not as a risk—but as a precision tool to enhance plant quality.
