Delivery Methods



Flower represents cannabis in its purest form. In this natural state, the Entourage Effect is most profound, providing full-bodied effects that aren't possible without all the plant compounds present. Consuming flower, whether in a pre-roll, glass piece or flower vaporizer, you get the full spectrum of compounds contained in the plant.

Prūf Cultivar flower is grown with care in our Clean Green Certified facility in Portland, Oregon, by horticulturists who've dedicated their lives to understanding this plant and its potential.


In partnership with Serra Wholesale Products and renowned confectioner Holly Hukill, we provide artful combinations of cannabis to Serra Chocolates, Gumdrops and Caramels. Each recipe is crafted to deliver a consistent experience guided by culinary invention. The variety of Types (THC-dominant, 2:1, 1:1, and CBD) serves needs and preferences previously neglected in a monotone, THC-focused market; moderate doses better suited for functional treats and incorporating into wellness routines.


A sleek, subtle package that delivers a consistent experience you can trust. Each strain-specific cartridge and disposable vaporizer pen is filled with honey-toned CO2 oil, processed in a cutting-edge facility by experts attuned to the individual qualities of each strain. Although effects can be instant for some, we recommend consumers wait forty-five minutes before additional inhalations.

The full-bodied effects from pristine product can’t be experienced with subpar consumption devices. Our selection of essential smoking tools, devices, and rechargeable batteries were designed based on real feedback from consumers, and built with reliable, high-quality components that last.

Handcrafted with premium Prūf Cultivar flower in small batches, our rosin ensures unparalleled freshness with a smooth finish. Our flower is harvested and cured for two days, then frozen to preserve the terpene-rich content. In a two-step refinement process, we utilize layered micron bags in ice water to separate resin glands from the raw plant material, then further refine using low temperatures and high pressure; allowing for one of the finest expressions of our premium cannabis in extract form.


Effective whole-plant extract doesn’t have to be complicated. Turn to our tinctures for a concentrated dose of edible cannabis in an easy-to use, easy-to-dose dropper. Potent and sophisticated, tinctures are made with precious care to retain the range of botanical compounds that make this plant so interesting. No frills, no fillers—just cannabis in its purest, most concentrated form. Technically classified as an edible, tinctures can be swallowed or mixed into tea or coffee. Coming in 2020.

Every cannabis strain possesses a unique ratio of THC to CBD. THC (tetrahydrocannabinol) is the psychoactive component of cannabis. CBD (cannabidiol) is a therapeutic compound showing promise at relieving pain and anxiety. A Type 1 plant, with high THC and low CBD, is more intoxicating than a plant than a mixed ratio Type 2, or a Type 3 high CBD/low THC plant.
