Understand the two factors that determine potency in flower:
Submit product to the laboratory in final sellable form; dried and cured. We recommend drying for at least seven days and curing for at least seven more days to achieve the sellable form.
Ensure the laboratory that you submit to has the proper instrumentation to conduct the analysis of your product. Express Toxicology has the ability to run potency on three different instruments:
• Industry standard
• Uses atomic mass to confirm analysis
LCMS/MS (Triple Quad)
• Uses the technology of the HPLC and the GC-MS for the most accurate analysis
Submit sufficient sample size to the lab. While we only require a minimum of one gram for potency, we recommend at least seven grams. As one of the largest labs in the state we have run more samples than most of our competitors. Our data analysis shows that customers who only submit a gram versus seven grams usually have potency an average of 2% lower than the potency found in the larger sample size. The reason for this is a large sample size taken from nine various locations of the batch reflects a more accurate analysis of the potency for the batch. A grower could select out a gram and could end up with higher potency but our experience over thousands of sample analysis shows the contrary.
Ensure your lab has passed proficiency testing from a third party provider such as Emerald or Phenova. Express Toxicology Services’ results are available upon request.
