At Greenleaf Labs, we understand that timing matters.

That’s why we use multiple GC-MS instruments to support terpene testing and help keep results moving efficiently without sacrificing accuracy.

Terpene results can give cultivators and processors valuable insight into aroma, profile, and product consistency — and our team is here to help you get the data you need.

Cannabinoids Beyond THC

THC is just one piece of the puzzle.
Cannabinoids like CBD, CBG, and CBN also play important roles.

Accurate potency results start with accurate moisture testing.

Moisture content can affect how potency is reported because cannabinoid percentages are often based on the total product weight. That means two samples with the same cannabinoid content may show different reported percentages if their moisture levels are different.

That’s why reliable moisture testing matters.

Accurate results depend on properly calibrated equipment, validated methods, consistent sample preparation, experienced laboratory personnel, and ongoing quality assurance.

At Greenleaf Labs, moisture testing helps support more accurate potency assessments, product consistency, and compliance decisions.

Behind every compliant product is careful microbial testing.

Here’s Abbey, our microbiologist, working in Greenleaf Labs’ micro room. The same type of PCR technology many people became familiar with during COVID testing is also used in cannabis testing to help detect contaminants like E. coli, Salmonella, and Aspergillus.

It’s one more way our team helps Oklahoma cannabis businesses protect their products, their patients, and their licenses.
