Post-harvest is 6–30% of production cost. The goal isn't the cheapest pound processed, it's the most gross profit per pound harvested. The math on spread, labor and yield.

The objective shouldn't be to process cannabis for the lowest possible cost. It should be to produce the most gross profit from every pound harvested.
It's no secret that cannabis post-harvest has its share of problems: yield loss, flower damage, high labor costs, inconsistent quality. It's also not uncommon for post-harvest to represent 6% to 30% of the total production cost of cannabis.
To maximize gross profit you have to balance labor cost, flower yield and quality. Labor affects your COGS. Quality affects your selling price. Yield determines how much of the cannabis you've already paid to grow actually becomes saleable flower. And yield isn't just about pounds: it's also about how much of your finished flower becomes A's versus B's and C's.
A facility manager gets a mandate to lower costs, automates, reduces headcount and increases throughput. But what happened to yield? If you save $30 per pound in labor but lose $70 per pound in saleable flower value, you didn't improve the economics of your operation. The same thing happens with grade: large flower goes into a machine and stemmy flower comes out. You still have the cannabis, but you may have turned A flower into B flower.
Your spread is the difference between the selling price of your flower and the value of your trim. If flower sells for $900/lb and trim sells for $50/lb, your spread is $850. Every additional percentage point of flower you recover is worth $8.50 per harvested pound. Five points is worth $42.50 per pound. At 10,000 pounds per month, that's potentially $425,000 in additional monthly value.
Commercial facilities process anywhere from a few hundred pounds to more than 10,000 pounds per month. The larger the facility, the more important relatively small improvements become. A $10/lb improvement at 500 pounds per month is $5,000. At 10,000 pounds, it's $100,000. The same math applies to yield.
Benchmark the labor required to buck, trim and sort one pound of cannabis, and don't just use someone's hourly wage. A $20/hour employee doesn't cost the company $20/hour; a basic fully burdened calculation might put that employee at around 1.2 times their wage. Even that isn't the whole cost: management, recruiting, hiring, training, PPE, HR, break rooms, janitorial, safety meetings, workers' compensation, turnover and payroll processing all sit on top.
And make sure you're counting everyone: the person bucking, the person feeding the machine, the people doing touch-up, the person sorting at the end and the supervisor keeping the line moving. Based on an industry poll and dozens of conversations with operators, the labor required to buck, trim and sort cannabis can range from roughly $15 to $160 per finished pound.
Yield is the percentage of dried, untrimmed flower that becomes saleable trimmed flower. If 100 pounds of dried, untrimmed flower becomes 80 pounds of saleable flower, that's an 80% yield. The right number changes with genetics, cultivation method, defoliation and flower structure, but roughly 80% is a useful target for well-defoliated flower.
If automation saves you $20 per pound in labor but costs you five points of yield, those five points are worth $42.50 per harvested pound against an $850 spread. You saved $20 and gave up $42.50. That's a bad trade.
Two processes can both produce an 80% flower yield and have completely different economics. One might produce 60 pounds of A flower and 20 pounds of B flower. Another might produce 40 pounds of A and 40 pounds of B. Both yielded 80 pounds. If A flower is worth substantially more than B, those aren't remotely the same result. Measure both total flower recovery and grade distribution.
Some automation produces high yields at the expense of your A/B ratio. Other automation produces extremely tightly trimmed flower at the expense of yield. Some systems advertise very high throughput, but that throughput can come at the expense of both. Don't choose a post-harvest process based solely on throughput, labor savings or even yield.
There is no single machine that solves this problem. The best solution is usually a combination of process, people and multiple pieces of equipment designed to reduce labor while protecting yield, grade and quality. By the time cannabis gets to post-harvest, you've already paid to grow it; post-harvest determines how much of that value you actually capture.
If you don't know your labor cost per pound, finished flower yield, A/B grade distribution, or how those numbers compare to other commercial producers, I can help. I work with cannabis operators every day and have benchmarked post-harvest processes across a wide range of facilities. Reach out and I'll benchmark your current post-harvest operation and calculate how to maximize gross profit per pound by balancing labor cost, flower yield, grade distribution and quality.
