Water Activity and Moisture Content Testing

Overview

Water activity measures how much of the water in cannabis is "available" to support microbial growth. Moisture content measures the total amount of water held inside cannabis material, expressed as a % of the product's weight.

Water activity

Colorado MED regulations require water activity testing for cannabis flower harvest batches except fresh frozen batches. Additional cases may include concentrates produced from failed yeast and mold material and decontaminated flower batches.

Moisture content

Moisture content testing helps operators evaluate product condition, storage risk, and consistency. We perform moisture content free of charge with a potency submission.

Turnaround

Water activity and moisture content testing are typically available in 2–3 business days, rush services available.
