The EZ Trim Harvest Calculator helps commercial cannabis growers estimate how long it may take to machine trim and hand touch-up a harvest using the EZ Trim Satellite Bud Trimmer.
The calculator models two parts of the trimming workflow:
1. Machine trimming with the Satellite Bud Trimmer
2. Manual touch-up of the flower that still requires additional finishing
Enter your harvest size and available touch-up labor to estimate how these two stages work together and how long the trimming process may take.
How the Calculator Works
The calculator uses the following production assumptions:
Satellite trimming rate: 1 pound per minute (approximately 453 grams/minute)
Flower requiring touch-up: 30% of the total trimmed weight
Employee touch-up rate: 5 grams per minute per employee
These assumptions create a simple model for estimating the relationship between machine-trimming capacity and the hand labor required after trimming.
The calculator is a planning tool, not a guarantee of production. Actual trimming and touch-up rates can vary based on cultivar, flower structure, preparation, dryness, trim readiness, machine settings, operator experience, and your finished-product standard.
Example: 100-Pound Harvest With 10 Employees
Suppose you have:
100 pounds of flower
10 employees available for touch-up
The calculator assumes that the Satellite can machine trim approximately:
1 pound per minute
At the calculator's 30% touch-up assumption, a 100-pound harvest produces:
100 lb × 30% = 30 lb requiring touch-up
Thirty pounds is approximately:
13,590 grams
Each employee is assumed to touch up:
5 grams per minute
With 10 employees:
10 employees × 5 g/minute = 50 grams/minute
The estimated touch-up time is therefore:
13,590 g ÷ 50 g/minute = approximately 272 minutes
or approximately:
4.5 hours of touch-up time
The Satellite itself would require approximately 100 minutes to machine trim 100 pounds at the calculator's 1-pound-per-minute assumption.
This example demonstrates an important point: machine throughput and total trimming throughput are not necessarily the same thing.
Once machine trimming becomes fast, the amount of flower requiring hand touch-up—and the number of people available to perform that touch-up—can become an important factor in total production time.
Calculator Assumptions at a Glance
Satellite Bud Trimmer: approximately 453 g/minute
Satellite Bud Trimmer: approximately 1 lb/minute
Assumed touch-up requirement: 30%
Touch-up generated at 30%: approximately 136 g for every minute of machine trimming at the modeled rate
Employee touch-up rate: 5 g/minute per employee
One employee: approximately 1 lb every 90 minutes
One employee: approximately 5.3 lb during an 8-hour workday
These values are the assumptions used by the calculator to estimate labor requirements. They should not be interpreted as guaranteed production rates for every harvest.
Why Touch-Up Percentage Matters
The 30% touch-up assumption is especially important.
It does not mean every harvest processed through a Satellite will require exactly 30% touch-up. It is the baseline used by this calculator to estimate labor.
Actual touch-up requirements depend heavily on the flower entering the trimmer.
Factors that can affect touch-up include:
Defoliation
Stem preparation
Flower size and structure
Consistency of dryness
Whether the flower is actually ready to trim
Satellite settings
Trim cycle time
Cultivar characteristics
Your definition of finished, shelf-ready flower
This is why EZ Trim treats touch-up as part of the complete trimming process, rather than evaluating a trimming machine only by its pounds-per-hour rating.
Machine Trimming Is Only Part of the Labor Equation
A machine can process flower very quickly while the overall trimming operation remains limited by downstream hand labor.
For example, at the calculator's assumptions:
Satellite output = approximately 453 g/minute
At 30% requiring touch-up:
Touch-up workload generated = approximately 136 g/minute
One employee working at 5 g/minute cannot keep pace with that workload.
Ten employees provide:
50 g/minute of touch-up capacity
Twenty employees provide:
100 g/minute
Approximately 27 employees at the modeled 5 g/minute rate would be required to provide roughly the same touch-up capacity as the calculator assumes is being generated while the Satellite continuously trims at 1 pound per minute.
That does not mean every Satellite operation needs 27 employees. It means the calculator can help you understand the relationship between machine speed, touch-up percentage, and available labor.
The Satellite does not necessarily need to run continuously, and touch-up can continue after machine trimming is complete.
Reducing Touch-Up Can Change the Entire Equation
One of the most important variables in the calculation is the percentage of flower requiring touch-up.
Consider a 100-pound harvest:
30% touch-up = 30 pounds requiring hand finishing
If process improvements reduced that to 20%:
20% touch-up = 20 pounds requiring hand finishing
At 10 employees working at the calculator's assumed 5 g/minute rate:
30 lb touch-up ≈ 4.5 hours
20 lb touch-up ≈ 3.0 hours
That is roughly 1.5 fewer hours for a 10-person touch-up crew on the same 100-pound harvest.
This is why improving the process feeding the trimmer can be just as important as increasing machine speed.
Preparation Affects Trimming Efficiency
For dry trimming, EZ Trim recommends treating preparation and trim readiness as part of the trimming process.
The workflow is:
Defoliate → Hang Dry → Buck → Equalize Dryness → Finger Test → Satellite Trim → Pre-Sort → Touch-Up / QC
Proper preparation helps the Satellite remove unwanted leaf efficiently while reducing unnecessary downstream correction.
Equalize Dryness Before Dry Trimming
Small and large cannabis flowers can dry at different rates.
Before dry trimming, EZ Trim recommends Equalizing Dryness so moisture is more consistent throughout the batch.
This helps reduce situations where some unwanted leaves are brittle enough to release while others remain pliable and attached.

Use the Finger Test
RH and drying time are useful indicators, but EZ Trim recommends physically testing the flower before machine trimming.
Select representative small, medium, and large buds.
Lightly disturb exposed unwanted leaf or rub two buds together.
PASS: The unwanted leaf is dry and brittle enough to snap or release.
FAIL: The leaf bends, folds, remains pliable, or stays attached.
If the unwanted leaf will not release when subjected to this simple friction test, it is unlikely to release efficiently during dry machine trimming.
Start With a Satellite Test Batch
For properly prepared dry flower, a useful Satellite starting test is approximately:
1 pound of flower
for approximately:
30–60 seconds
Then inspect the result.
Different cultivars and batches may require changes to:
Airflow
Suction
Rotor speed
Rotor direction
Agitation
Batch time
The objective is not simply to run every batch for the same amount of time. The objective is to find the settings and trim time that produce the desired result with the least unnecessary handling and touch-up.

Use Touch-Up as a Process Metric
Touch-up labor can tell you something about the effectiveness of the entire trimming process.
If an unusually large portion of the flower requires correction after machine trimming, investigate why.
Ask:
Was the flower properly defoliated?
Was excess stem removed?
Was dryness consistent?
Did representative flower pass the Finger Test?
Were the Satellite settings appropriate?
Was the batch under-trimmed?
Rather than assuming that a fixed amount of hand finishing is unavoidable, track the percentage of each harvest requiring touch-up.
Over time, this creates a useful operational metric:
What percentage of our machine-trimmed flower actually requires additional hand finishing?
Lowering that percentage can reduce labor even if machine throughput remains exactly the same.
Calculate Labor Cost Per Pound
The same information can also help evaluate trimming cost.
For touch-up labor:
Touch-Up Labor Cost = Number of Employees × Hours Worked × Hourly Labor Rate
Then:
Touch-Up Labor Cost per Pound = Total Touch-Up Labor Cost ÷ Total Harvest Pounds
For a more complete comparison, include machine operators and other trimming-related labor as well.
This allows commercial growers to compare processes based on finished-product labor cost per pound, rather than looking only at machine throughput.
Plan the Complete Harvest
The Harvest Calculator focuses on the relationship between Satellite trimming and touch-up labor.
The EZ Trim Harvest Playbook goes further by explaining how the stages before and after trimming affect the complete commercial harvest:
Defoliate → Hang Dry → Buck → Equalize Dryness → Finger Test → Trim → Pre-Sort → Touch-Up/QC → Final Cure → Final Sort → Package

Harvest Calculator FAQ
What does the EZ Trim Harvest Calculator calculate?
The calculator estimates machine-trimming and hand touch-up requirements using the Satellite Bud Trimmer. It models Satellite throughput at approximately 1 pound per minute, assumes 30% of trimmed flower requires touch-up, and calculates touch-up labor at 5 grams per minute per employee.
Why does the calculator assume 30% touch-up?
Thirty percent is the baseline assumption used by the calculator to estimate labor. It is not a guarantee that 30% of every harvest will require touch-up. Actual results depend on flower preparation, dryness, cultivar, machine settings, trim time, and finished-product standards.
How fast can one employee touch up cannabis?
The calculator uses an assumed rate of 5 grams per minute per employee, equivalent to approximately one pound every 90 minutes or approximately 5.3 pounds during an eight-hour workday.
How fast does the Satellite Bud Trimmer trim cannabis?
The calculator models Satellite production at approximately 1 pound per minute. Actual production depends on flower condition, preparation, cultivar, machine settings, batch size, and desired trim quality.
How many employees do I need for cannabis touch-up?
It depends on harvest size, the percentage of flower requiring touch-up, the employee touch-up rate, and how quickly the work needs to be completed. The calculator uses these variables to help estimate the required labor.
How can I reduce cannabis touch-up labor?
Start upstream. Proper defoliation, bucking, consistent dryness, passing the Finger Test, and appropriate Satellite settings can all affect the amount of manual correction required after trimming.
Why is the Finger Test important for dry trimming?
The Finger Test checks whether unwanted leaf is brittle enough to release from the flower. If the leaf bends or remains attached when physically disturbed, the flower may not yet be ready for efficient dry machine trimming.
Is the Harvest Calculator a guarantee of production?
No. It is a planning model based on defined assumptions. Actual production and labor requirements vary between harvests and operations.
