Episode 149: Lighting Cannabis Right: 2025 Science & Strategy with MIGRO

·1 hr 48 min·2 clips

Cannabis grow lighting intensity has tripled in 10 years—from 500 to 1400 micromoles.

Tad opens by framing the podcast as science-based and pointing to the upcoming Cannabis Cultivation and Science Conference in Bozeman. He introduces Shane Torpey as the founder of MyGrow and as someone who turned a hobby into a grow lighting business. Shane's background in manufacturing, engineering, and construction gives the discussion a practical edge. The conversation stays centered on lighting and photobiology, not product promotion. Tad frames the topic in a way growers will recognize right away. The questions start from real cultivation problems instead of abstract theory. Shane also says MyGrow uses social media to help educate growers and help them reach their potential. The tone stays conversational and corrective rather than polished or sales-heavy. They dig into how light intensity is measured. They also spend time on what those measurements can fail to capture. A major thread is the difference between a plant's momentary photosynthetic response and its ability to live under that same intensity for a full grow. Shane cautions against treating instantaneous chamber readings as proof that a plant can be run at that power for 12 hours a day across 60 days. That distinction becomes one of the episode's main lessons. The discussion also complicates the simple idea that more light always means better results. Tad raises the question of why plants developed under sunlight can still get stressed when conditions turn hot or intense. Shane and Tad work through the idea that adaptation, environment, and plant structure all matter. The episode does not rush past uncertainty. Instead, it pauses where the science gets messy and explains why the messy parts matter to growers. The result is a measured conversation about how to think about fixtures, intensity, and stress without oversimplifying any of them. It leaves the listener with a more careful way to evaluate lighting claims. It also reinforces the show's habit of turning expert detail into field decisions.

As heard by us

A careful look at cannabis lighting that keeps the plant, not the headline number, at the center.

This is a grounded look at cannabis lighting and photobiology, and it stays most useful when it keeps returning to the plant rather than the number on a meter.
