The Business of Growing Cannabis At Scale: Lessons on Costs, Labor and Operations

Most cannabis operators think about cultivation in terms of genetics, lighting and yields. Experienced cultivation directors think about something else entirely: infrastructure, labor efficiency, inventory management and operational discipline.

Dave Myrowitz, Director of Cultivation at Flora Arbor in Illinois, begins every morning the same way: opening a dashboard that tracks HVAC performance, environmental stability, canopy sensors and irrigation data across the facility. For Dave, healthy plants are the result of healthy systems, and every operational decision ultimately affects production costs, product quality and profitability.

His perspective offers a blueprint that extends well beyond cultivation. Whether operators are expanding production, evaluating capital expenditures or trying to improve margins in an increasingly competitive market, the principles remain remarkably consistent.

Great Cultivation Starts With Systems

One of Dave’s priorities each morning is reviewing the facility’s environmental data remotely before anyone enters a grow room. HVAC performance, temperature, humidity, vapor pressure deficit (VPD), irrigation moisture, electrical conductivity, and pH all feed into operational decisions throughout the day.

The approach reflects a broader shift taking place across commercial cannabis cultivation. Rather than reacting to problems after they appear, successful operators increasingly rely on continuous monitoring to identify small deviations before they become expensive failures.

Stable environmental conditions reduce operational risk, create repeatable production cycles, and allow cultivation teams to make smaller, more predictable adjustments throughout the plant’s lifecycle.

HVAC Is a Profit Center

If there is one area where Dave believes operators consistently underestimate investment, it is environmental control.

“You will never overbuild your HVAC system,” he says.

His recommendation goes even further: when engineers believe a facility has sufficient dehumidification capacity, operators should still plan for roughly twenty percent more than projected. Plants frequently outperform expectations, increasing irrigation volumes and moisture loads that quickly overwhelm undersized systems.

While HVAC often represents one of the largest capital expenditures in a cultivation facility, Myrowitz argues that properly sizing environmental infrastructure prevents far more expensive production losses later. Equipment failures, inconsistent environmental conditions, and inadequate dehumidification can quickly erase whatever savings operators realized by minimizing upfront investment.

For expanding operators, environmental infrastructure is less an expense than a form of operational insurance

Inventory Management Is Working Capital Management

Cultivation requires balancing two competing priorities: avoiding production interruptions while limiting the amount of cash tied up in inventory.

Myrowitz currently purchases nutrients every quarter, buying enough product to support approximately three months of production while taking advantage of bulk discounts. As the facility expands, however, storage limitations will likely require more frequent monthly purchasing despite losing some purchasing leverage.

That decision illustrates a broader financial principle familiar to manufacturers across industries. Bulk purchasing lowers unit costs, but inventory occupies warehouse space and locks up working capital that might otherwise support expansion or operational improvements.

As production scales, inventory strategy becomes as much a financial decision as an operational one.

Compliance Carries Costs Beyond Licensing

Regulation affects cultivation long after a license is issued.

Myrowitz describes Illinois as one of the most heavily regulated cannabis markets he has operated in, requiring weekly inventory reconciliations, detailed plant tracking, frequent inspections and extensive documentation.

Those requirements translate directly into additional labor hours, administrative work and compliance infrastructure that operators must incorporate into their cost structure. Every plant tag, inventory audit and regulatory inspection consumes resources that might not exist in other states.

The lesson for operators is straightforward: compliance should not be treated as overhead after a facility opens. It is a recurring operating expense that varies significantly from one jurisdiction to another and should be incorporated into financial planning from the outset.

Labor Efficiency Is About Preventing Expensive Mistakes

Labor represents one of the largest controllable expenses inside a cultivation facility.

But Myrowitz argues that productivity isn’t measured solely by speed.

He recalls training an employee during harvest who attempted to remove mature plants from trellising too aggressively, ripping flower from the branches in an effort to finish the task more quickly. Because any flower that contacted the work table no longer met quality standards, thousands of dollars of premium product were effectively downgraded in exchange for saving only minutes of labor.

The experience reinforces an operational principle applicable well beyond cannabis cultivation: efficiency is about maximizing value while minimizing costly errors.

In many cases, slowing down at the right stage of production produces better financial outcomes than rushing through critical processes.

Not Every Cost Should Be Minimized

Operational excellence requires knowing where to save money, and where additional spending generates higher returns.

Myrowitz cites premium HVAC systems, air purification, high-quality microbial inoculants, and careful hand trimming of premium flower as investments that consistently justify their higher costs through improved quality and reduced operational risk.

Conversely, he points to examples where using more product does not improve results. Applying excessive rooting hormone, for instance, can actually reduce cloning success while increasing material costs.

The objective is allocating resources where they produce measurable operational value.

Standard Operating Procedures Scale Businesses

Technology alone cannot create consistency either.

According to Myrowitz, the foundation of scalable cultivation remains people supported by well-designed standard operating procedures.

“The two most valuable resources that we have in the facility are our genetics and our people,” he explains, emphasizing that long-term consistency comes from hiring capable teams, documenting processes, and building systems that operate independently of any single individual.

That philosophy mirrors broader trends across manufacturing industries, where standardized processes increasingly determine whether businesses can expand production without sacrificing quality or operational control.

Operational Excellence Is Becoming Cannabis’ Competitive Advantage

As cannabis markets mature, competitive advantages are shifting away from simply producing flower toward producing it consistently, efficiently and profitably.

Environmental controls, inventory planning, workforce training, compliance management and disciplined capital allocation may lack the excitement of new genetics or record THC levels, but they increasingly determine which operators build durable businesses.

The operational challenges facing cultivators—from environmental controls and labor management to inventory planning and capital allocation—will be central to the conversations at IgniteIt’s California event on October 7. Bringing together cultivators, operators, manufacturers, investors, and industry leaders, the event will focus on practical strategies for improving efficiency, reducing costs, and building resilient cannabis businesses.

For professionals looking to turn operational excellence into a competitive advantage, it offers an opportunity to learn directly from the people solving these challenges every day.
