This week on the Cannabis Cultivation and Science Podcast, we're diving deep into lighting and photobiology with Shane Torpey, founder of MIGRO. With a background in engineering and construction, Shane turned his passion for growing into a global grow lighting company known for trusted reviews and educational content.

We break down what’s working—and what’s not—in cannabis lighting for 2025, including:

Far-red and intra-canopy lighting

LED vs. HPS and how to transition

Maximizing PPFD without added CO₂

Dimming schedules at sunrise/sunset

The impact of lenses on LED light penetration

What really matters when choosing a grow light

Emerging technologies shaping the future of cultivation

Whether you’re scaling a facility or dialing in your home grow, this episode gives you the tools to make smarter lighting decisions rooted in science and real-world data.
