📋 Overview
Recording harvest weight is a critical step in the cannabis cultivation workflow. This process captures the official wet weight of your harvested plants and creates the compliance documentation required for regulatory reporting.
When you record a harvest weight, GrowerIQ:
- Creates an official weight record for the harvest batch
- Generates a signature audit trail for compliance
- Triggers downstream workflows (drying, processing)
- Updates inventory quantities for Health Canada reporting
Regulatory Compliance
Accurate harvest weights are required for Health Canada reporting. All harvest weight entries require three signatures to ensure proper oversight and accountability.
✅ Prerequisites
Before recording a harvest weight, ensure:
| Requirement | Details |
|---|---|
| Batch in Harvesting stage | The batch must be in the Harvesting stage |
| Plants remaining | Plant count must be greater than 0 |
| Scale calibrated | Use a calibrated scale appropriate for the weight range |
| Three users available | Different users must provide Weighed By, Checked By, and Approved By signatures |
📝 Step-by-Step Instructions
Step 1: Navigate to Your Batch
- Go to Cultivation & Processing from the main menu
- Find your batch in the batch list or use search
- Click on the batch to open the batch detail page
Step 2: Open the Record Harvest Weight Dialog
- In the Actions panel, click Record Harvest Weight
- This button only appears when the batch is in Harvesting stage with plants remaining
Step 3: Enter Harvest Details
Harvest Name (METRC only)
If your organization uses METRC integration, select or enter a harvest name.
Reduction of Plants
Enter the number of plants being harvested. You can harvest all plants at once or partial amounts for multi-harvest workflows.
Multi-Harvest
You don't have to harvest all plants at once! Enter fewer plants than the total to create a child batch and continue maturing the remaining plants.
Total Harvest Weight
Enter the total wet weight in grams (g). For imperial units, the system will convert automatically.
Timestamp
Select the actual date and time the harvest occurred.
Scale Selection
Select the scale used for weighing (optional but recommended for audit trails).
Step 4: Complete Required Signatures
Three Signatures Required
Every harvest weight entry requires three separate signatures. This is a compliance requirement and cannot be bypassed or reduced.
Complete the signatures in order:
| Signature | Purpose | Who Should Sign |
|---|---|---|
| ⚖️ Weighed By | Confirms the person who physically weighed the harvest | The operator who performed the weighing |
| 👁️ Checked By | Verifies the weight was recorded correctly | A second team member who witnessed/verified |
| ✅ Approved By | Final approval of the weight record | Supervisor or authorized approver |
How Signature Authentication Works
Your organization can configure whether password authentication is required:
Password Authentication OFF (Default):
- Select the signer's name from the dropdown
- Signature is recorded immediately
- Faster workflow for trusted environments
Password Authentication ON:
- Select the signer's name from the dropdown
- Enter the user's password to authenticate
- Provides additional verification
Organization Setting
Password authentication is controlled by your organization's Enable Signature setting in Admin > Organization Settings. Contact your administrator to change this configuration.
Best Practice: Use Different Signers
For maximum compliance and oversight, use three different people for each signature role. While the system may allow the same user in some workflows, regulatory best practice is to have independent verification.
Step 5: Review and Submit
- Review all entered information
- Ensure all three signatures are complete
- Click Submit to record the harvest
🔄 Multi-Harvest Workflow
You do not have to harvest all plants at once. Multi-harvest lets you:
- Harvest in stages - Take some plants now, leave others to mature
- Create child batches - Each partial harvest creates a new batch with the harvested weight
- Finalize later - When you harvest the remaining plants, the original batch is finalized
Example:
| Action | Plants | Result |
|---|---|---|
| Start | 100 plants | Original batch |
| First harvest | 60 plants | Child batch created with 60 plants' wet weight |
| Second harvest | 40 plants | Original batch finalized with remaining weight |
Source and Child Batches
After a partial harvest, the original batch is marked as a Source Batch and links to its Child Batches in the batch detail view.
💡 Tips and Best Practices
⚖️ Weighing Accuracy
- Zero your scale before each weighing session
- Weigh immediately after harvest to capture accurate wet weight before moisture loss
- Use calibrated scales and select them in the dialog for audit compliance
✍️ Signature Management
- Use different signers - Best practice is to have three different people sign
- Plan ahead - Ensure all three required signers are available before starting
- Password security - If password authentication is enabled, never share passwords
📅 Backdating
- You can backdate harvest weight records to the actual harvest time
- The timestamp must be between when the batch entered Harvesting stage and now
- Do not select future dates
⚠️ Troubleshooting
Common Issues
| Issue | Cause | Solution |
|---|---|---|
| Button does not appear | Batch not in Harvesting stage | Verify batch stage is Harvesting, not Flowering or Drying |
| Cannot save weight | Missing signature | Ensure all three signatures are complete |
| Password rejected | Wrong password or user | Verify correct user selected, re-enter password |
| Invalid date error | Timestamp out of range | Select a date between stage entry and now |
| User not in dropdown | Lacking permissions | Contact admin to grant harvest permissions |
Weight Not Saving
The most common cause is incomplete signatures. Ensure all three signatures (Weighed By, Checked By, Approved By) are completed before clicking Submit.
➡️ What Happens Next
After recording harvest weight:
- ✅ Stage Advances - The batch moves to the Drying stage automatically (if all plants harvested)
- ✅ Inventory Updates - Your inventory now shows wet grams (g-wet) instead of plants
- ✅ Compliance Record - Weight record with signatures is stored for audits
- ✅ Next Action - You can proceed to Record Dry Weight once drying is complete
