Before recording plantings in Metrc, it is important to understand how the system defines mother plants, immature plants, and immature plant batches. These are tracking concepts used to ensure all plants are fully traceable back to a legitimate source.
What is a Mother Plant?
A mother plant – while not intended to be harvested for sale – is a cannabis plant maintained for the purpose of producing cuttings (clones), which helps drive maximum propagation success and consistent, high-quality yields.
In Metrc, mother plants are not tracked as a separate plant type. They can be assigned and recorded the same way as any other vegetative or flowering plant. A plant is considered a “mother” based on how it is used in operations. Tracking mother plants is ideal for maintaining strong control and visibility in cultivation.
When clones are taken, Metrc requires the new plants to be linked to the tagged source plant. That source plant is commonly referred to as the mother plant.
What is an Immature Plant?
An immature plant is a cannabis plant that has not entered the vegetative phase. Vegetative and Flowering phases are defined by state rule and are typically based on physical characteristics or by lighting schedules or grower intent.
In Metrc, immature plants may be tracked either:
- as part of an immature batch, or
- as individually identified plants once they reach the size or stage that requires tagging
Smaller, non-flowering plants are tracked as a vegetative plant individually tagged at a specific height per state rules and regulations.
What is an Immature Plant Batch?
An immature plant batch is a single Metrc record that represents a group of strain-specific immature plants that are tracked together. It functions as a count of plants tied to a common origin.
An immature batch must:
- consist of a single strain
- originate from one source (a plant or a package)
- remain within the maximum plant count allowed by the jurisdiction, commonly up to 100 plants
Immature batches are temporary. Once plants reach the point at which individual tracking is required, they must be moved out of the batch and tracked as individual plants.
How Metrc tracks the creation of new plants
Metrc does not allow plants to be created without a documented source. Any time new plants are introduced into inventory, the system requires that they be linked to an existing plant or package.
Acceptable sources include:
- a tagged plant at the facility, such as a mother plant
- a package of seeds
- a package of immature plants received through an external transfer
This requirement maintains traceability and ensures that all plants in the system can be accounted for during inspections and audits.
Recording clones from a Mother Plant
When clones are taken from a mother plant, Metrc treats the action as the creation of new active inventory. For that reason, the system separates cloning into two related steps.
Step 1: Cuttings are documented as being taken from a specific tagged plant. This establishes the origin of new plants.
Step 2: Those cuttings are created into an immature plant batch. Metrc uses an immature plant batch as the link between the source plant and the newly created batch. This process ensures the batch record clearly shows its origin.
Once created, the immature plant batch appears in the active Immature Plant Batches inventory, showing the plant count, strain, batch name, quantity, and originating source.
If the source plant is being maintained as a long-term mother, it may continue to be tracked in the vegetative phase after cloning. Any temporary growth phase changes required during the cloning process are system requirements and do not reflect actual cultivation intent.
Recording plants from seeds or incoming clones
Not all immature plants originate from in-house cloning. Plants grown from seed or received from another licensed facility are recorded using a package as the source.
In these cases, the package is unpackaged directly into an immature plant batch. The batch record will reflect the package tag as the origin.
Another source of origin is cuttings created from other clones in an immature plant batch. Those are known as tissue cultures and the batch record will reflect the immature plant batch as the origin.
Regardless of origin, the same rule applies: every immature plant batch must be linked to a single, documented source.
Maintaining accurate batch counts
Plant counts may change over time due to plant loss or data entry errors. Metrc requires inventory records to reflect what physically exists at the facility.
If plants in an immature plant batch fail to thrive or are no longer viable, those plants must be destroyed in Metrc so the batch count remains accurate.
Some jurisdictions allow limited adjustments to batch counts within a short window after creation. Outside of that window, destruction is the standard method for correcting counts.
Transitioning out of the immature stage
Immature plant batches are used only during early growth. Once plants reach the size or height defined by state rules, they must be tracked as individual plants and moved to the next growth phase – vegetative.
At that point, plants are moved out of the immature plant batch, assigned individual plant tags as required, and tracked in the appropriate growth phase. This transition is a standard part of cultivation tracking in Metrc.
Keeping planting records audit-ready
Accurate planting records require ongoing maintenance. Immature batches must be updated as plants grow, move, or are removed from inventory.
This includes:
- recording plant destruction when losses occur
- transitioning plants to individual tracking at the appropriate stage
- confirming that Metrc records match physical inventory at the facility
Most compliance issues related to planting records result from mismatches between recorded system data and on-site conditions. Consistent recordkeeping helps prevent errors, corrective actions, and supports smoother inventory audits and inspections.
Metrc workflows and state requirements may change over time, so it’s important for licensees to routinely stay on top of both Metrc and state guidanceand update internal procedures as needed.
Frequently Asked Questions: Recording plantings in Metrc
How do I record clones from a mother plant in Metrc?
Clones are recorded by linking new plants to a tagged source plant. Cuttings are first documented as being taken from the source plant, then converted into an immature batch using an immature plant package. This process ensures the batch is traceable to the originating plant.
What is an immature batch in Metrc?
An immature plant batch is a group record used to track non-flowering plants together. It represents a count of plants of the same strain from a single source and is used until individual plant tracking is required.
How many plants can be in an immature batch?
Most jurisdictions limit immature batches to 100 plants, though limits may vary by state. If more plants are created, they must be split into multiple batches.
Do immature plants need individual tags?
No. Immature plants may be tracked as part of a batch without individual RFID-enabled tags in most jurisdictions, but not all. Once plants reach the stage at which tagging is required by state rule, they must be assigned individual tags and tracked separately.
Can clones be taken from flowering plants?
Yes. Metrc allows clones to be taken from a vegetative or flowering plants. The system requires the source plant to be identified so the new batch can be linked correctly.
How are plants grown from seeds recorded?
Plants grown from seeds are recorded by converting a seed package into an immature plant batch. The batch record will show the seed package as the origin.
What should I do if plants in a batch die?
If plants die or are no longer viable, they must be destroyed in Metrc so the batch count reflects actual inventory. This maintains accurate records for inventory management, inspections, and audits.
Can I correct mistakes in an immature batch?
Some batch counts may be adjusted within a limited time after creation, depending on state rules. Other details, such as batch name, cannot be edited. If those are incorrect, the batch may need to be discontinued and recreated.
Do mother plants require special tracking in Metrc?
No. Mother plants are tracked the same as other plants. While the term “mother plant” describes how the plant is used in operations, there is a specific Mother Plants tab in Metrc available to improve tracking capabilities.
What are the benefits of tracking mother plants in Metrc?
- Data-driven decisions: Make informed choices with insights into survival rates and lifecycle health.
- Preserve genetic integrity: Ensure the most valuable genetics stay strong and productive.
- Maximize propagation success: Achieve higher clone success rates and more reliable results.
- Scalable insights: Cultivators are better prepared for future growth with clear, connected data on every plant’s legacy.
Tracking mother plants and clones provides licensed cultivators the opportunity to easily monitor the health and lineage of these plants, which is a powerful tool in gaining unparalleled control and visibility to these valuable plants.
