Automation is transforming the way cannabis is grown.

Knowledge and experience combined with an integrated, complete solution make Wadsworth Controls the first choice for cannabis production.

Beginning with an advanced, integrated controller, software that tracks and replicates best growing practices, while offering remote access, a light dep design that’s been keeping greenhouses dark for over 40-years and a venting system that’s responsive and easy to install.

It’s all here.
