Schedule III Compliance

Pharma-Grade Drying, Curing & Storage for the New Era of Cannabis

Indoor cannabis cultivation with plants hanging from the ceiling in a controlled environment.

With cannabis moving to Schedule III, the industry is entering a world built around pharmaceutical-grade expectations. Drying, curing, and storage are no longer “art and intuition” they become controlled, validated manufacturing steps subject to GMP-style oversight.

Cultivators who can demonstrate consistency, documentation, and microbial control will be positioned to supply future medical, pharmaceutical, and export markets. Cannatrol® with Vaportrol® technology delivers that advantage.

Why Water Activity (aW) Matters Under Schedule III

Vertical farm with plants growing in a controlled environment.

In pharmaceutical manufacturing, water activity (aW) is a recognized standard for controlling microbial risk and product stability.

  • USP chapters (922 and 1112) define aW as a critical indicator for safe, stable non-sterile drug products.
  • For dried cannabis, scientific guidance aligns around ~0.55–0.65 aW as the ideal finished range for microbial safety, terpene protection, and long-term stability.
Cannatrol is the only system engineered around vapor pressure and water activity, not just room humidity, delivering a repeatable, controlled drying curve every time.

  • Repeatable results that support process validation
  • Clear parameters suitable for SOPs, batch records, and QMS integration
 Water-Activity-Driven Results
  • Controls the environment to achieve finished product in a validated aW range
  • Aligns directly with FDA/USP expectations for microbial risk mitigation
  • Supports risk-based microbial testing strategies for consistent batches
 Clean, Closed, and Document-Friendly Systems
  • Food-grade interiors and easy-clean surfaces
  • Fewer product touch points and reduced cross-contamination risk
  • Clear chain-of-custody for each batch through defined dry/cure cycles
 Stability & Quality Protection
  • Prevents over-drying and unnecessary weight loss
  • Preserves terpenes, color, and trichome integrity
  • Maintains long-term product stability for medical and export markets
As regulations tighten, cultivators will need proven, validated control, not guesswork. Cannatrol is the ready-now platform that helps you bridge traditional cultivation and pharmaceutical-grade production.
