At Green Method Farms, we can tell you exactly what is in your bottle. We grew the hemp ourselves, and know the exact CBD potency. We have passed lab testing for THC below 0.3%. You can scan the QR code on the bottle to see the lab reports from the exact batch of CBD that was used in that tincture. We farmed, processed, formulated, and bottled the products within a 20 mile radius in the high desert of Central Oregon. We can guarantee the highest quality CBD oil in every bottle.
