The Ultimate Experiment

Get a peek at what we’ve been up to the past year and how our Cultivar Discovery program led to new, never-before-seen cultivars.

Just under a year ago, we embarked on a project to discover more diverse genetics.
We wanted to take our collective knowledge of cultivation, plant science and clone library to a new level, combining it all in the most efficient (borderline obsessive-compulsive) experimental crop of what we imagined would be either super strong, super interesting or super CBD-dominant.

But it turned into much, much more. This little gardening experiment transformed into a journey that brought the Prūf Cultivar team to the cutting edge of cultivation science, demonstrating just how subjective plant chemistry can be and how little we’ve seen of cannabis’ true potential thus far.

1000 → 10
We started with 1000 genotypes; 1000 seeds with promising genetic backgrounds. After a few weeks of low-intensity light and precisely watering by hand with syringes, leaves were established, which allows plant health scientists to glean quite a bit of genetic data right off the bat. Upon reviewing leaf-based observations, the sample group was cut down to half—about 464 plants.

Then we brought all of those 464 plants through flowering and harvest. As they developed, we sniffed, studied and sniffed some more, cutting that number down over time. Using an in-house gas chromatograph, we ran our own preliminary testing on site to better guide our instincts. After reviewing the developing terpene profiles, cola quality and plant health, we narrowed down the group to the 32 most interesting and promising cultivars.

Third Time’s A Charm
Then we sniffed some more. Conducted another round of testing. We noted which phenotypes were coming out more compact or lanky and took those characteristics into consideration as we further pared down the number. We considered everything—down to the sizes and placement of buds.

But in order to bring this experiment to a true conclusion, we couldn’t make a final selection based on a single example of the star cultivars. Not to mention these test harvests only amount to 1.5-2 lbs apiece—not enough to judge the lifelong potential of a strain. So we didn’t narrow it down to the final selection of winners until getting through 3 cycles of these mini crops. That way, we weren’t only honing growing conditions and consistency— we were able to start predicting harvest dates.

And by our calculations, Oregonians are about to see the first extremely unique and truly original fruit of our labors hit the shelves.

Discover Cannabis

Navigating Cannabis

Cannabis is among the most chemically diverse plants on earth. Prūf's careful formulations of Type and Terpenes guides exploration of your ideal strains.

Discover Cannabis


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.

THC Rich

THC-Rich strains containing low-to-zero amounts of CBD.

Mixed Ratio

Strains with a mixed ratio of THC and CBD.

CBD Rich

CBD-Rich strains containing low-to-zero amounts of THC.


Terpenes are what make up a plant's essential oils, driving richness in flavor and experience. Each Prūf strain contains multiple terpenes and other than Type, terpene profile has the biggest effect on how you experience cannabis in your body.
