Plantworks Seattle - Indoor Urban Cannabis Microfarm

In 2016 we renovated a warehouse in the Seattle neighborhood where we live, and built Plantworks, our Indoor Urban Cannabis Microfarm. We are committed to sustainable urban farming and a boutique micro-farming model. We are proud to run our farm in the community that we call home, for over two decades.


When we started our farm, we carried with us the lessons and observations learned from years of working the standard indoor, cannabis “blueprint” for other people. We wanted to eliminate the traditional mistakes of the past— heavy energy consumption, overzealous nutrient saturation, a thoughtless landfill waste stream. We built Plantworks guided by civic and environmental stewardship.

As of Summer 2020, we are an EnviroStars-recognized Indoor Urban farm. Plantworks is recognized for our low water usage; nutrient recapture; resource use reduction; waste-stream diversion; composting, reusable packaging; and for buying locally.

Sustainability practices

  • We are an all-LED facility, and farm-wide we use Forever Green Indoors (FGI) lighting. We were an early adopter of the FGI square grow light for vegetative plants, and we run FGI Lightpanel 500s exclusively in our flower rooms.

  • All of our plants are grown in 100% compostable, inert substrate. This reduces the potential for plant disease and pests from living soil and allows fine-tuned precision with our custom, all-natural plant feed recipes. 

  • As part of our commitment to sustainable urban farming, we do not use supplemental CO2 in our grow rooms. Our recirculated, filtered air exchange keeps our micro-batch flower rooms at a steady level of ambient CO2.


Community partners

Our commitment to Urban Farming is our commitment to be an Urban Maker. In 2019 we became the first cannabis industry member of Seattle Made, a city-wide collective of diverse urban manufacturers actively producing goods inside Seattle’s urban core.  


Plantworks is also a member of the Seattle Good Business Network, because of our commitment to buy, produce and reinvest locally.


Plantworks is Grower-Owned and Operated, and also Worker-Owned. In 2021 we will seek like-minded people with a dedicated work ethic to help grow our cooperative.

Plantworks is grown in the city we love, where our farm is guided by our values - our commitment to the community and cannabis we cherish.
