The majority of our partners are greenhouse growers using natural methods to nurture and support clean cannabis cultivation from start to finish.

Little River Farm provides us with curated cannabis, focused on creating the highest quality while using the most natural methods possible. With self-produced fish fertilizer and opaque panels that expose growing plants to the different moon phases, this farm goes to great lengths to cultivate the definition of natural cannabis. The most potent thing they use for combatting bugs is neem oil, a natural oil popular among organic farmers. We appreciate that level of clean.
