Sampling Procedures

Sample Size for Testing.
How much should I supply for testing?

Due to recent changes to OMMA rules and regulations, we will be required to receive both a PRIMARY and RESERVE sample on all Full Compliance Tests starting on Friday, December 11, 2020. 

This change will impact our required sample weights, as noted in the chart below. It is important to ensure that all samples are homogenized thoroughly in accordance with OMMA regulations. All products must be separated into two (2) equal samples labeled PRIMARY and RESERVE prior to drop off.

As always, we are here to answer any questions or concerns. Please give us a call during laboratory hours and we will be happy to help!

Sample Collection

Cannabis plants have distinct growth patterns which influence how cannabinoids are distributed throughout the flowers. Flowers located on the primary stalk at the very top of the plant will yield the highest numbers, while flowers located on lateral stalks down towards the base of the plant will have the lowest numbers.

Because of this, we recommend specific methods of collection to ensure the most accurate profile results. Collect small bits of flower randomly from all portion of the plant – many small buds totaling 1 gram per test will be potentially more accurate than a single large bud.
