METRC Compliance Software for California Cannabis Cultivators
California tracks every plant in Metrc, and its Department of Cannabis Control (DCC) is actively rewriting the rules around it. Mustashio keeps your cultivation records and your Metrc data in step, so new requirements land on a system that is already organized.

A Mature Market With a Moving Rulebook
California's legal cannabis market runs on Metrc, with the DCC as its regulator. For cultivators that means every plant, harvest batch and package is tagged and reported, and the DCC's inspectors compare what they count on site with what your records say.
The rules are not standing still. In 2026 the DCC put cultivation updates into effect, clarified harvest batch tracking, and opened rulemakings on plant group tagging and track-and-trace safeguards. A platform that already holds your cultivation, inventory and compliance data in one place makes each change a configuration question rather than a scramble.
Mustashio's Core + METRC plan syncs plants, packages and inventory with Metrc through the API, with RFID tag and plant-tag reconciliation built in.
Three calendar days to update Metrc
California regulations require cultivators to update the track and trace system within three calendar days of cultivation activities. The DCC has said defined timeframes reduce the risk of inversion and diversion.
2026 DCC Rulemaking Tracker for Cultivators
The rule changes that affect California cultivation and track-and-trace, based on the DCC's rulemaking page as of November 11, 2026.
| Rulemaking | What it does | Status |
|---|---|---|
| DCC-2025-01-R Cultivation updates; sanitation standards |
Removes redundant provisions, clarifies harvest batch tracking and labeling, and sets the first minimum sanitation standards for licensees handling exposed cannabis. | Effective July 1, 2026 |
| DCC-2025-03-R Pesticide testing |
Updates action levels for pesticide residue testing of cannabis products. | Effective October 1, 2026 |
| DCC-2026-03-R Group tagging of cannabis plants |
Proposes group tagging to reduce cost and tag waste. Inspectors would still verify plant counts against track and trace, and each group would be tied to a location. | Proposed · comment closed Oct 2, 2026 |
| DCC-2026-02-R Track and trace updates |
Proposes that all parties to a transfer approve it before a manifest is generated, tightens data entry requirements, and adds retailer tax and COA requirements. | Proposed · comment closed July 20, 2026 |
Proposed rules may change before adoption. Confirm current status on the DCC's rulemaking page.
What Each California Cultivator Needs From Software
Cottage and specialty grows
Small teams need compliance that doesn't eat grow time. Automated Metrc sync and flat pricing with no long-term contract keep overhead down.
Small and medium cultivators
More rooms and more staff mean more handoffs. Task, team and resource planning with unlimited users keeps everyone on one record.
High tag-volume operations
Large plant counts make tag mistakes expensive. RFID tag and plant-tag reconciliation and MustashioGrid™ rack visualization surface mismatches early.
