Greenstone Manufacturing was born from tremendous respect for both consumers and plant medicine. That’s why we use only solventless methods. Our focus on purity and love for cannabis is what sets us apart. We strive to master natural solventless hash that is safe to consume and puts the emphasis back on the basics of cannabis consumption.

A potent and clean smoking experience is bliss- it’s pure and it’s healing. It’s what we stand for.

Classic Hash for the Modern Smoker

Our desire is to bring the art of classic hashish to the forefront of a new and booming Oklahoma market while also leading the edge of pure, solventless concentrate production. Impeccable quality is what we built our family-owned and operated company on. As a result, we produce the finest top-shelf concentrates available with an emphasis on purity and transparency because we know it matters.
