About this episode
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 MetabolitesJasmonates in Growth, Trichomes, and CannabinoidsMetabolic Responses to Water DeficitTrichome Sampling & Quantification MethodsTrigonelline as a Biomarker for Drought Stress (Preprint)Propagation & Clonal Fidelity in Cannabis ResearchAdditional 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.
