True Northwest provides required, I-502, quality assurance testing to keep you in compliance with state mandated laws. We test flowers, extracts, and certain edibles and offer the following analytical services:

I-502 Quality Assurance Tests

  • Potency – THC, THC-A, CBD
  • Moisture
  • Foreign Matter Inspection
  • Microbiological Screening
  • Residual Solvents

Grow Check

Our grow check service assists producers in quantifying potency levels at various stages of growth, in order to know when THC and/or CBDs are at their peak, helping to determine best harvest dates.

Wastewater Consultation

Every county in Washington has different rules regarding how to discharge grow water. Pesticides, herbicides, nitrates and nitrites cannot be discharged into septic systems, and in some counties, city sewer systems.

We can help you mitigate your wastewater issues. We implement the same standards at our labs to safely handle our contaminated wastewater. We can help you achieve and maintain compliance and save fish and groundwater at the same time.
