Our recent post about microbiology testing touched on the prevalence of aspergillus and its potential impact on growers in light of the new cannabis testing requirements in Oregon. Let’s get into some additional detail on this widespread organism, and point you toward some extra resources on the topic.
What is aspergillus?
Aspergillus refers to a group of hundreds of fungi species found in...Read More
Have you heard about the new microbiology tests for cannabis in Oregon? Of course you have! Everyone has, and everyone is talking about it, because the early results have been a surprise to say the least, so it’s become a core focus for labs and farms alike.
The success and stability of the cannabis community depends on our collaboration through this new phase of testing. Let’s get into some...Read More
With three shelf tests completed, with anywhere from 8 to 11 strains re-tested, the through line continues to be variance. This is not unique to our industry. Variance exists in the pharmaceutical, food, environmental and energy industries – even with rigorous testing and regulatory requirements in place. As in our industry, different testing methods, equipment, and analytical techniques can...Read More

It’s not unique to cannabis — analytical variance is the name of the game across labs of all kinds, from pharmaceuticals to animal feed. Since this is such an important aspect of lab testing, we’re diving deeper into the topic…
First of all, what do we mean when we say analytical variance?
Analytical variance is the variation in results when testing cannabis samples. It acknowledges the...Read More
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
You’re already aware of the regulation change — as of this month, all cannabis in Oregon is required to pass heavy metals testing. The complete rules under the Public Health Division can be found here, and as stipulated in OAR 333-007-0415, the heavy metals standards and action limits are as follows (ug/g = micrograms per gram):
Arsenic — 0.2 ug/g
Cadmium — 0.2 ug/g
Lead — 0.5 ug/g
Mercury —...Read More

It’s time for another round of shelf testing! We have 11 new strains right out of dispensaries here in Oregon, and each was approved for retail sale after testing by one of ten different cannabis labs. The kicker is that this time we included a strain that was originally tested right here at Pree! We’re taking a bit of our own medicine to see how the Pree-tested flower fared after a few months...Read More
