The METRC cultivation workflow follows regulated cannabis as it moves from an immature plant batch into individually tracked plants, through vegetative and flowering growth, into a harvest, and finally into packages containing usable harvested material.
The software workflow makes much more sense when you first understand what is physically happening inside the cultivation facility.
A simplified cultivation lifecycle looks like this:
Source Material → Immature Plant Batch → Individually Tracked Plants → Vegetative Growth → Flowering Growth → Harvest → Drying & Post-Harvest → Finished Packages
Each stage represents a change in the physical cannabis inventory. METRC is the regulatory compliance record used to document those changes in jurisdictions that require the system.
The goal is not simply to click through a sequence of screens. Employees need to understand what physical inventory each record represents, where that inventory came from, what changed, and where it went next.
Good cultivation tracking begins in the grow—not at the computer.
Regulatory information reviewed: August 2026
First Understand the Physical Workflow
Before learning the electronic workflow, imagine a real cannabis plant moving through a commercial cultivation operation.
- A seed germinates or a clone is taken from a source plant.
- The young plants are managed together as immature inventory.
- Plants reach the point where the jurisdiction requires individual tracking.
- The cultivator assigns individual plant identifiers.
- Plants grow vegetatively.
- Selected plants transition into flowering production.
- The flowering plants are harvested.
- Harvested material dries and is processed into usable and unusable material.
- Usable harvested cannabis becomes one or more packages.
- Those packages can then continue through testing, processing, transfer, distribution, or another authorized activity.
METRC records the regulatory history connecting those stages.
The Cultivation Workflow Step by Step
Step 1: Begin With a Traceable Plant Source
Regulated plant inventory should have an identifiable origin.
The specific source can depend on the jurisdiction and business. Examples can include:
- Seeds contained in a tracked package
- Clones taken from an individually tracked source plant
- Authorized immature plants received from another licensed source
- Other plant material permitted under the applicable state program
The important concept is traceability. The new plant inventory should connect back to a recognized source rather than simply appearing in the regulatory record.
Step 2: Create an Immature Plant Batch
Young cannabis plants are commonly managed as immature plant batches before individual plant tracking is required.
A batch allows multiple young plants with a common source and relevant identifying information to be managed together during propagation or early growth.
Operationally, the cultivation team should know:
- Where the plants came from
- How many plants were created
- The applicable strain or cultivar
- Where the batch is physically located
- The date the batch was created
- Which employee is responsible for maintaining the physical count
If 100 clones are recorded in a batch, the physical batch should reasonably account for those 100 plants until documented activity changes that number.
Immature Plant Batch Example
| Source | Tracked mother or source plant |
| Clones taken | 100 |
| Immature batch created | 100 plants |
| Plants that fail during propagation | 8 |
| Remaining viable plants | 92 |
| Plants selected for continued production | 80 |
The physical operation should be able to explain what happened to all 100 plants.
The final electronic treatment of failed, destroyed, transferred, retained, or promoted plants must follow the applicable state’s rules and METRC procedures.
Step 3: Transition Plants Into Individual Tracking
At the point required by the jurisdiction, selected immature plants transition into individually tracked plant inventory.
Each plant receives its own unique identifier.
This is a major change in the regulatory record:
One batch record representing many plants → individual records representing individual plants
The cultivation team should verify the physical plants before this transition.
- Count the plants physically present.
- Confirm which plants will continue into production.
- Confirm the strain or cultivar.
- Confirm the destination room or location.
- Prepare the required plant identifiers.
- Apply identifiers to the correct physical plants.
- Verify that the electronic records correspond to the physical tags.
Do not create individual electronic plant records first and then try to figure out which physical plant belongs to which identifier afterward.
Plant Tag Management
Plant identifiers connect physical plants to individual regulatory records.
A strong plant-tag procedure should address:
- Secure storage of unused identifiers
- Assignment of identifiers to physical plants
- Verification after tags are applied
- Location and room changes
- Missing or damaged tags
- Destroyed or harvested plants
- Periodic physical tag audits
The plant identifier should remain associated with the correct physical plant throughout the period in which individual tracking is required.
Step 4: Vegetative Growth
Vegetative plants are individually tracked plants that have not yet transitioned into flowering production.
During vegetative growth, common physical activities can include:
- Moving plants between rooms or areas
- Transplanting into larger containers
- Removing unhealthy plants
- Taking clones from authorized source plants
- Changing production groups
- Preparing selected plants for flowering
Not every physical horticultural activity creates the same reporting requirement. The applicable state rules determine which events must be reported and when.
Operationally, however, plant location and plant identity should never become ambiguous.
Step 5: Move Plants Into Flowering
When plants enter flowering production, their physical status changes and the corresponding regulated plant records should reflect the applicable growth phase.
Before moving a group into flowering, a cultivation team should verify:
- Which physical plants are moving
- The identifiers attached to those plants
- The destination flowering room or area
- The physical plant count
- The employee responsible for confirming the move
- Any plants intentionally remaining in vegetative growth
This is one of the simplest examples of why physical operations and electronic reporting must communicate.
If the cultivation crew moves 75 plants but the compliance employee reports only 73, the facility immediately has two different versions of plant inventory.
Plant Movement and Room Changes
Plant movement is a common source of tracking problems because cultivation teams frequently move plants for operational reasons.
- Spacing changes
- Transplanting
- Production scheduling
- Environmental management
- Pest or disease isolation
- Vegetative-to-flowering transitions
- Facility reorganization
A reliable facility should have one defined way for cultivation employees to communicate reportable plant movement to whoever maintains the regulatory records.
What Happens When a Plant Dies?
Not every plant reaches harvest.
Plants can be removed due to disease, pests, damage, poor performance, cultivation decisions, or other authorized reasons.
A removed plant should not simply disappear physically while remaining active electronically.
The facility needs a procedure connecting:
- The physical plant
- The plant identifier
- The reason for removal
- Any required plant weight or waste information
- The final physical disposition
- The corresponding regulatory record
Exact waste and plant-destruction requirements vary by jurisdiction.
Step 6: Harvest the Flowering Plants
Harvest represents another major inventory transition.
The regulated inventory changes from individually tracked living plants into harvested cannabis material associated with a harvest record.
Individual Plants → Harvest Batch
Before creating the harvest record, the cultivation or harvest team should verify which physical plants are actually being harvested.
- Confirm plant identifiers.
- Confirm the number of plants.
- Confirm the strain or cultivar.
- Confirm the harvest date.
- Confirm the physical harvest location.
- Use a documented weighing procedure.
Harvest Weight
Harvest weight is an area where poor procedures can create large discrepancies.
Facilities should define:
- What material is included in the recorded weight
- When the material is weighed
- Which scale is used
- Whether containers or tare weights are involved
- Who records the weight
- Who verifies the weight
- How the information reaches the person making the regulatory entry
If two employees weigh the same harvested material differently, METRC cannot determine which physical weight is correct.
The facility must resolve that operational issue.
Drying and Moisture Loss
Freshly harvested cannabis contains substantial moisture. As the material dries, physical weight decreases.
That natural change is one reason harvest tracking can be confusing to new users.
A simple physical example:
| Recorded harvested material | 100 lb |
| Physical waste removed during processing | 10 lb |
| Remaining dried usable material | 25 lb |
| Remaining weight difference | Primarily moisture or other supported post-harvest loss |
This is only an illustrative example—not a target yield or regulatory formula.
The actual harvest record needs to be handled according to the jurisdiction’s current rules and the physical activity that actually occurred.
Harvest Waste
Harvest processing can generate unusable plant material.
Depending on the applicable rules and workflow, the operation may need to document waste separately from usable harvested material.
A good harvest procedure should answer:
- What the facility considers waste under the applicable rules
- When waste is weighed
- Who verifies the weight
- How waste is physically controlled
- How it is reported
- How final destruction or disposal is documented when required
Step 7: Create Packages From the Harvest
When usable harvested material is ready to leave the active harvest inventory, it can be moved into one or more packages according to the applicable workflow.
Harvested Material → Package
For example, one harvest may eventually produce separate physical inventories such as:
- Finished flower
- Trim
- Other usable harvested material permitted by the jurisdiction
Each package represents a defined quantity of regulated inventory and receives the appropriate unique identifier.
The package should be connected to its source harvest so traceability continues.
Example: Turning One Harvest Into Packages
Imagine a finished harvest containing usable flower and trim.
| Package A | 10 lb finished flower |
| Package B | 8 lb finished flower |
| Package C | 5 lb trim |
The physical material represented by those packages should correspond to the quantities reported when the packages are created.
The packages now become separately traceable regulatory inventory that can continue through other authorized activities.
Step 8: Finish the Harvest
A harvest should not remain active indefinitely after its physical inventory has been completely accounted for.
Before finishing a harvest, verify that applicable physical activity has been accounted for, including:
- Usable material moved into appropriate packages
- Applicable waste recorded
- Post-harvest weight changes addressed appropriately
- No usable physical material remains unaccounted for
Official Metrc guidance explains that finishing a harvest removes it from active harvest inventory after usable material has been packaged and unusable material has been appropriately accounted for. The treatment of remaining harvest weight and required deadlines can vary by jurisdiction.
The Entire Workflow in One View
| 1. Source | Seed, clone, plant, or other authorized source inventory |
| 2. Immature Batch | Young plants managed together before individual tracking |
| 3. Individual Plants | Selected plants receive individual identifiers |
| 4. Vegetative | Individually tracked plants remain in vegetative growth |
| 5. Flowering | Plants transition into flowering production |
| 6. Harvest | Tracked plants become harvested material |
| 7. Drying / Post-Harvest | Material loses moisture and is separated into usable material and applicable waste |
| 8. Package | Usable harvested inventory becomes one or more uniquely identified packages |
| 9. Finish Harvest | Harvest record is closed after applicable material is accounted for |
The Most Important Connection to Understand
Every step should connect backward to the inventory that created it.
Plant Source → Batch → Plant → Harvest → Package
This is what makes the inventory traceable.
A finished package should not be an isolated number. Its history should lead backward through the harvest and plant inventory from which it originated.
Common Cultivation Tracking Mistakes
- Creating the wrong number of immature plants
- Failing to maintain accurate batch counts
- Applying the wrong plant identifier to a physical plant
- Moving plants physically without reporting the corresponding activity
- Changing growth phases incorrectly
- Leaving destroyed plants active
- Selecting the wrong plants when creating a harvest
- Entering incorrect harvest weights
- Failing to document harvest waste
- Mixing material before traceability is properly maintained
- Creating packages with incorrect quantities
- Creating packages from the wrong source harvest
- Leaving completed harvests active unnecessarily
A Better Cultivation Reporting System
The person entering regulatory data should not have to walk through the entire facility every evening trying to figure out what happened.
The cultivation operation should produce organized information.
A simple internal workflow might look like:
Cultivation Activity → Employee Documentation → Supervisor Verification → Compliance Reporting → Exception Review
For example, a flowering-room move might require the cultivation lead to provide:
- Date
- Source room
- Destination room
- Plant identifiers
- Physical plant count
- Employee completing the move
- Supervisor verification
The compliance employee receives complete information instead of trying to reconstruct the activity from memory.

Practice This Cultivation Workflow Interactively
The Secund Look Track-and-Trace Practice Lab now lets learners work through the cultivation inventory concepts described on this page inside a fictional training environment.
Instead of only reading about plant batches and inventory movement, the learner makes decisions, receives feedback when quantities do not reconcile, and watches the fictional inventory ledger update as plants move through the cultivation lifecycle.
Cultivation Exercise 1: Clone Batch & Propagation
The first live exercise begins with a fictional Lemon Cherry Gelato clone batch containing 100 plants.
- Review the original 100-clone source batch.
- Account for 10 observed propagation failures.
- Move 90 viable plants into a new immature plant batch.
- See why the original source record still shows 10 plants remaining.
- Recognize that physically failed inventory and regulatory inventory do not automatically resolve at the same moment.
- Make intentional mistakes and see how incorrect counts, sources, locations, or activity information create inventory problems.
100 starting clones → 90 viable plants move forward → 10 remain in the source record pending later accounting.
The same fictional inventory will continue through future Practice Lab exercises covering individual plant tracking, flowering, harvest creation, post-harvest inventory, packages, and final reconciliation.
The Practice Lab is an independent Secund Look educational simulator using fictional inventory. It is not official Metrc software, is not connected to a live regulatory account, and does not replace official Metrc or state-required training.
METRC Cultivation Workflow FAQs
What is an immature plant batch?
An immature plant batch is a regulatory record used to manage multiple young cannabis plants together before individual plant tracking is required. Source, strain, quantity, location, and other applicable information remain associated with the batch.
When does a cannabis plant need its own METRC tag?
The exact point at which individual tagging is required depends on the jurisdiction. Operators should follow their state’s current regulations and official METRC guidance rather than assuming the same plant-size or growth-stage threshold applies everywhere.
What is the difference between vegetative and flowering plants in METRC?
Vegetative and flowering represent different cultivation growth phases for individually tracked plants. The physical plant status and corresponding regulatory record should remain aligned, subject to the terminology and reporting rules of the applicable jurisdiction.
What happens to a METRC plant when it is harvested?
The individually tracked plant becomes associated with a harvest record. Harvested material can then be tracked through drying and post-harvest activity until usable material is moved into packages and applicable waste is accounted for.
How do I make a flower package from a harvest?
Conceptually, usable flower is removed from the harvest inventory and placed into a uniquely identified package tied to the source harvest. The exact screen workflow, fields, permissions, timing, and package requirements depend on the jurisdiction and current version of the system.
What happens to moisture loss during drying?
Harvested cannabis loses physical weight while drying. Facilities should accurately record physical waste and usable material according to their jurisdiction’s rules. Operators should follow their own state’s current requirements for how remaining harvest weight and post-harvest loss are handled.
Why does my harvest not reconcile?
Common causes include incorrect initial weights, inconsistent weighing procedures, undocumented waste, material removed before records are updated, incorrect package quantities, packages created from the wrong harvest, or mixing physical inventory before traceability is maintained.
Does METRC replace cultivation-management software?
No. METRC is a regulatory compliance and seed-to-sale reporting tool. A cultivator may separately use cultivation-management software, environmental controls, labor systems, IPM records, scheduling tools, accounting systems, or other operational platforms. Where those systems describe regulated inventory activity, the relevant information should remain consistent and explainable.
