With our proprietary weed grading system, we're able to assess the objective quality of cannabis flower and pre-rolls, and now you can too. 

We've created a fully digital, repeatable process that helps you take your understanding of cannabis to a whole new level. 

We guide you through every step of the process with our simple, illustrated process. 

Free for Public Use

We are we making the grading system free to use? It's simple - it is a powerful tool that we believe will disrupt the industry for the better. 

As an industry and community, it's time to move beyond binary conversations about THC and Terpenes. We no longer need to rely on expensive, and often unreliable lab testing to tell us what constitutes good weed. We need a more comprehensive system that is more applicable to us as consumers; that has room to cater to our unique tastes and preferences. For far too long cannabis consumers have had to settle for less. No more, we say.
