In this episode ofThe Cannabot Chronicles, we’re diving deep intothe science of light intensity and how it affectscannabis yield, potency, and photosynthesis in indoor environments. 🌱💡
This study from theUniversity of Guelph explores the relationship betweenphotosynthetic photon flux density (PPFD) andcannabis plant performance, revealing thatyield increases linearly with higher light levels—up to an incredible1,800 µmol·m²·s⁻¹. But whileinflorescence density and harvest index improve,cannabinoid potency remains stable, and terpene levels show only slight variation.
Key insights we cover:
🔥More Light = Bigger Yields – But is there a saturation point?
🌡️The Science of PPFD – How leaf-level vs. whole-plant photosynthesis responds.
🧪Cannabinoids & Terpenes – Why more light doesn't always mean more potency.
⚡Balancing Energy Use & ROI – How to optimize light for cost-effective production.
If you're serious aboutmaximizing your indoor grow, this episode is packed withpractical strategies and cutting-edge research to help you fine-tune yourlighting setup for the best economic return. Tune in and learn how tolight up your grow the right way! 🌱🔥
