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.
