Rooted in Tradition. Growing the Future.

1809 Underground is a licensed Canadian cannabis nursery located in Ontario. We focus on commercial reliability, plant health, and genetic integrity. Built by growers, for growers, we deliver vigorous clones and teens that help producers eliminate mother rooms, expand flowering space, and increase output.
Our team has led large-scale cultivation programs across Canada and returned to our roots to build a nursery model that values clean propagation, consistent performance, and transparent service. Through in-house breeding and careful pheno-hunting, we curate cultivars that perform in real facilities – not just on paper.

Working with us is simple: explore our Cultivars page to review availability and lead times, visit Our Roots to learn our story, or Contact Us to plan your next cycle. If you’re seeking a dependable partner for clones, teens, and elite genetics, 1809 Underground offers the experience and systems to support your production goals. As a licensed Canadian cannabis nursery, we ship to licensed facilities nationwide and stand behind every tray we root.
