In our Shelf Testing series, we re-test strains from local dispensaries. Variance is the recurring theme, because of the inherent variability in the plant and the final product. As we’ve discussed, there are several contributing factors. In the first of this two-part series, Patrick Ray – one of our Pree field reps and former grower – helps us understand some of the implications on the farm...Read More

It’s not so much a matter of whether our results will differ — we know they will to some extent. It’s a matter...Read More
