Cannabis Cultivation and Science Podcast

In this episode, I sit down again with Bryant Mason of Soil Doctor Consulting for a fast-paced, practical conversation on the fundamentals growers often overlook. We dig into low-tech monitoring tools, pH behavior in organic systems, water testing basics, under-canopy lighting, and smarter phosphorus and nitrogen management. If you want a grounded look at what actually moves the needle in cultivation, this one delivers.

In this episode, I sit down with Dr. David Hawley to talk about what plants actually care about when it comes to light. We dig into how to think in DLI instead of just chasing PPFD numbers, why uniformity matters more than raw power, and how spectrum fine-tunes rather than defines your grow. David breaks down what far-red and UV really do (and don’t do), how to manage leaf temperature as light intensity climbs, and why clean lenses and smart dimming often beat a fancy new fixture. It’s a practical, myth-busting chat about using light as a tool—not a trophy—and it’s packed with tips you can apply right away whether you’re running a living soil facility or just trying to dial in a tent at home.

MIGRO joins Tad to break down the latest in grow lighting for 2025. They cover far-red, intra-canopy lighting, LED vs. HPS, maximizing PPFD without CO₂, dimming schedules, and what really matters when choosing a grow light. A must-listen for growers looking to boost yields through smarter lighting.

In this episode of the Cannabis Cultivation and Science Podcast, we’re joined by Dr. Michael Gutensohn, an expert in plant physiology and secondary metabolism, to explore the intricate relationship between environmental stress and the production of secondary metabolites in cannabis. We discuss how various abiotic stressors—such as light intensity, temperature fluctuations, and nutrient availability—can influence the biosynthesis of key phytochemicals, including cannabinoids, terpenes, and flavonoids. Dr. Gutensohn shares insights from his research on plant defense mechanisms, metabolic signaling pathways, and how growers might harness controlled stress to enhance both plant resilience and phytochemical output. Whether you’re a cultivator aiming to fine-tune your grow environment or a scientist delving into cannabis metabolomics, this episode offers valuable, research-backed perspectives on optimizing secondary metabolite production through stress modulation.

Dr. Nadia Sabeh is the best in the industry when it comes to air flow and environmental controls related to plants. It was great to get her back on the podcast to talk about what she sees coming up in 2025 and how we can be more efficient with our grow room in regards to energy consumption.
