A Note About Us

Stone leaf is “vertically integrated”, meaning we grow our own flower, make our own edibles/concentrates and retail our products out of our store in Windsor, VT.  We decided to pursue vertical integrations so that we could guarantee quality and safety at every step of the process – with every product we make. We are proud of our approach and psyched to be part of this uniquely Vermont venture.

Our Mission

As a vertically integrated company, we control every aspect of the process from seed to sale. We believe in the cleanest, most natural way of growing. Our hand selected genetics are from years of selection and breeding and our flower is hand trimmed producing artisanal flower and THC rich products. 80%+ of our genetic stock was bred by the team over the years. We use no solvents in our processing facility and no chemical fertilizers, pesticides or herbicides ever! We use a mixture of regenerative and Korean Natural Farming techniques at our grow that helps build the soil to improve over the years instead of killing it.
