Welcome to Billy Green Master Control

Helping cannabis growers improve their crops—and their control.

Meet Billy Green. Grower, consultant and creator of Master Control.

With more than 30 years in cannabis cultivation, I help growers understand their crops, improve their facilities and bring it all together—from hands-on consulting to connected control.

What is Master Control?

Explore the system Billy built to bring irrigation, root-zone data and environmental monitoring together. Used in his own grow and continually refined through experience and collaboration.

The grower behind the system

I built the system I wanted in my own grow.

The crop is always telling you something. The challenge is connecting what you see in the room with what the data is showing you.

I wanted irrigation, root-zone readings and the environment in one place—with the context to make them useful. So I built Master Control, inside my own facility—and I keep refining it as I refine my grow.

The plant comes first

Built around the plant. Built to help the grower.

A schedule tells you when water was planned. Root-zone readings help you understand the response. The room’s conditions give you another part of the picture.

Bring those observations together, and your experience has more to work with—not another screen to watch in isolation.

Experience shared

Together, better.

The more experience we share, the more we can learn. Master Control keeps improving through use, feedback and working with other growers.

I built it and use it in my own grow. I keep refining the system alongside the room, learning from the crop and the experience we share.
