From HPS to LED. From LED to Red Sandwich. 🔴
What if the next major leap in cannabis lighting efficiency isn't a new fixture, but an entirely new way of delivering light?
Years of research into photobleaching, spectrum, intensity, and under-canopy lighting have led us to an entirely new approach to growing cannabis.
🔴 3.4 µmol/J efficacy
🔴 ~21% reduction in lighting OPEX
🔴 Better bud grade and uniformity
🔴 Quality and yield maintained
Top light + under-canopy light. A smarter way to distribute photons. A whole new way to think about cultivation.
And the science behind it? That's where things get really interesting.
In this clip Dr. Dave Hawley breaks down the research and what it means for the future of cannabis cultivation. Want to dig deeper into the science and how this works? Watch the full webinar on Red Sandwich on our YouTube
