Series Overview

A FRONT-ROW SEAT TO COMMERCIAL CULTIVATION TRIALS

Grow Room Weekly is an unfiltered, data-driven YouTube series documenting the realities of commercial cannabis cultivation from inside Faven Lighting's R&D facility in Sacramento, California.

What the series covers

Each episode takes viewers behind the scenes of active cultivation trials, ongoing research, and the day-to-day challenges of operating a grow. Topics range from Far Red applications and under-canopy lighting strategies to irrigation demand, canopy development, environmental troubleshooting, and crop performance analysis.

Why Faven started it

The mission is to bring greater transparency to the industry by openly sharing real-world findings, practical lessons, and the continuous pursuit of better harvests. Instead of polished highlight reels, GRW documents the full process so growers can follow the reasoning, understand the outcomes, and apply what makes sense in their own rooms.
