Building the Greenhouse Is Only Half the Project

We can engineer a sophisticated commercial greenhouse.

That includes specifying the structure, HVAC equipment, irrigation system, fertigation equipment, lighting, sensors, environmental controls, and automation.

It also involves modeling capital costs, developing construction schedules, and coordinating contractors.

But there is another question that deserves just as much attention:

Who is going to run it?

A multimillion-dollar greenhouse does not become a successful food-production operation simply because construction is complete.

It becomes successful when the people inside it understand how the facility works, how the crop responds, what the data means, how to recognize problems early, and what to do when conditions move outside the expected range.

That is why greenhouse operator training, greenhouse management planning, standard operating procedures, and commissioning need to be part of project development—not something added after construction.

Capital can buy infrastructure. It cannot instantly create an experienced operating team.

Investment in automation will allow farms and greenhouses to work smarter and deliver higher quality jobs, ensuring they continue to meet the growing demand for top-quality products for Canadians and consumers around the world..

Canada’s Greenhouse Industry Is Growing

The question of who will operate these facilities is becoming increasingly important as Canada’s greenhouse industry expands.

Statistics Canada reported that Canadian greenhouse fruit and vegetable sales reached approximately $3.1 billion in 2025, an increase of 10% from the previous year.

The sector is also technologically sophisticated. Agriculture and Agri-Food Canada describes Canada’s indoor agriculture sector as technologically advanced and notes that greenhouse producers have made substantial investments in automation and other technologies to improve production efficiency, reduce labour requirements and improve product quality.

But technology does not operate in isolation.

People still need to understand it.

Labour and skills remain recognized challenges across Canadian agriculture. In 2024, the job-vacancy rate in crop production—largely horticulture—was 4.0%, compared with 3.3% across the broader economy. Agriculture and Agri-Food Canada continues to identify labour availability and skills as constraints on production capacity and future growth.

Greenhouse, nursery and floriculture operations employed 64,682 people in 2024, making them one of the largest agricultural employers in Canada.

The challenge, therefore, is not simply building more growing space.

It is developing the operational capacity required to manage it.

The Operator Has Become a Systems Manager

Running a modern commercial greenhouse is no longer simply a matter of knowing how to grow plants.

A greenhouse operator may need to understand interactions between:

• crop physiology and crop stage;
• temperature and relative humidity;
• vapour pressure deficit;
• irrigation frequency and volume;
• nutrient concentration, EC and pH;
• lighting and daily light integral;
• CO₂;
• HVAC and ventilation;
• pumps, valves and dosing equipment;
• sensors and calibration;
• alarms and control logic;
• integrated pest management;
• labour scheduling;
• food-safety procedures;
• production forecasting; and
• operating costs.

Changes in one part of the system can influence several others.

Increasing ventilation may change temperature, humidity and CO₂ concentration. Irrigation decisions can affect root-zone EC, crop health and drainage. A faulty sensor can cause an automated system to make perfectly logical decisions based on incorrect information.

This is why modern greenhouse management increasingly requires people who can think across plant science, mechanical systems, automation and data.

The greenhouse operator is becoming a systems manager.

But even as machines learn best practices, complex biological systems will remain that require human intervention.

Why Automation Does Not Eliminate the Need for Skilled Operators

Automation is often presented as a solution to agricultural labour shortages. It can reduce repetitive work, improve consistency, and give operators better control over complex greenhouse systems.

However, automation does not eliminate the need for operational expertise. Instead, it changes the type of skills greenhouse teams need.

Agriculture and Agri-Food Canada has identified both skills and training and automation and technology as major workforce issues. As farms adopt more advanced technology, employees need stronger technical skills and better access to training.

Installing sophisticated systems without developing the people responsible for using them can simply replace one operational problem with another.

An automated greenhouse still needs operators who can answer questions such as:

• Why did this alarm occur?
• Is the sensor reading believable?
• Should the system remain in automatic mode?
• Why is irrigation demand different today?
• Does the crop response match the environmental data?
• What happens if a pump, valve, controller, or communication network fails?
• Which problem requires immediate intervention, and which one can wait?

Good automation gives operators better tools, visibility, and control. It does not replace operational judgment.

At NuLeaf Farms, The Leaf brings climate, lighting, irrigation, fertigation, sensors, alarms, and other critical greenhouse systems into a coordinated control environment. The goal is not to remove the grower from the operation, but to give the operating team a clearer understanding of what is happening across the facility and greater control over how the system responds.

Greenhouse Operator Training Cannot Start at Handover

One of the biggest mistakes in greenhouse development is treating operator training as a final project task.

A typical approach looks like this: construction finishes, equipment suppliers demonstrate their systems, manuals are handed over, the operating team receives several days of training, and then production begins.

Technically, the facility may have been commissioned. Operationally, however, the organization may still be learning how to use it.

A stronger approach begins controlled environment agriculture training before the greenhouse enters full production. Operators should understand the facility architecture, equipment, control philosophy, and production strategy while the systems are still being installed and commissioned.

This gives the operating team an opportunity to ask questions while the designers, integrators, contractors, and equipment suppliers are still involved. It also gives them the context needed to understand how the complete facility works together.

They do not simply learn which button to press. They understand why the system was designed that way, what should happen after that button is pressed, and how to respond when the system does not behave as expected.

SOPs Turn Knowledge Into Repeatable Operations

Experienced operators carry a great deal of knowledge, but relying on one person’s memory creates operational risk.

Clear standard operating procedures (SOPs) help make critical greenhouse tasks consistent and repeatable. These may include irrigation and fertigation, nutrient preparation, pH and EC management, sensor calibration, crop scouting, sanitation, IPM, equipment inspections, alarm response, maintenance, and emergency procedures.

The goal is not paperwork—it is consistency. Once procedures are standardized, performance becomes easier to measure, compare, and improve.

NuLeaf supports this approach through commissioning, hands-on training, workflows, and SOP development for day-to-day greenhouse and indoor farm operations.

Commissioning Should Include the People Running the Facility

Commissioning should answer more than:

Does the equipment work?

It should also answer:

Can the operating team run the complete system?

There is an important difference.

A pump may function correctly during an equipment test.

But the operator also needs to understand when that pump should run, what conditions trigger it, what normal flow and pressure look like, what alarms are associated with it and what actions to take if its performance changes.

The same applies to environmental controls, fertigation systems, lighting, HVAC, sensors and automation.

Effective greenhouse commissioning therefore needs to test the facility under realistic operating conditions while involving the people who will ultimately be responsible for it.

NuLeaf’s existing project-development approach reflects this principle: construction is followed by commissioning, calibration and verification of integrated systems under operating conditions rather than treating the greenhouse as a collection of independently installed components.

Plan for the First Year, Not Just Opening Day

Opening day receives a lot of attention, but the first twelve months deserve even more.

That is when operators begin encountering situations that cannot be fully recreated during classroom training—different seasons, changing crop stages, equipment wear, unexpected pest pressure, shifting irrigation demand, new employees, sensor drift, alarm events, and ongoing maintenance requirements.

Production targets that looked straightforward in a spreadsheet can also become much more complicated in a live facility. That is why operational support should extend beyond the initial handover.

Performance needs to be reviewed against actual operating data. Key questions include:

• What was expected to happen, and what actually happened?
• Where did labour hours go?
• Which crops performed according to plan?
• Where did energy, water, or nutrient use exceed assumptions?
• Which alarms occurred repeatedly?
• Where are operators still relying on workarounds?

This is where farm-management data becomes especially valuable.

NuLeaf’s The Root platform is designed to connect production, labour, environmental, and operational information so growers can evaluate performance, identify recurring issues, and find opportunities for improvement rather than relying entirely on reactive troubleshooting.

What Operational Readiness Should Include

A greenhouse development plan should have an operational readiness workstream running alongside design and construction.

Before Construction

Define the organizational structure and identify who will be responsible for crop management, facility operations, automation, maintenance, food safety and production planning.

During Design

Include operators in discussions about workflows, equipment accessibility, automation interfaces, alarms, redundancy and maintenance.

During Construction

Begin system-specific training and develop SOPs around the equipment that is actually being installed.

During Commissioning

Train operators using live equipment and realistic operating scenarios rather than relying exclusively on manuals and classroom demonstrations.

Before First Crop

Validate crop recipes, irrigation and fertigation strategies, environmental setpoints, sanitation procedures, emergency procedures and data-collection requirements.

During the First Production Cycles

Review performance frequently. Compare actual production, labour requirements, crop quality and operating costs with the assumptions used during project planning.

After Stabilization

Once the greenhouse reaches a stable operating stage, optimization should continue.

The goal is not to keep operating exactly as the facility did on opening day. Over time, the team should use production experience, operational data, and lessons learned to refine crop strategies, workflows, system settings, and resource use.

A greenhouse should not operate exactly the same way in year five as it did in year one. The organization should become more efficient, more consistent, and better at running the facility with every production cycle.

Build the Team While You Build the Greenhouse

There is nothing wrong with investing $20 million in a greenhouse.

The problem is investing millions in infrastructure while treating operational capability as an afterthought.

A greenhouse project should have two development paths happening at the same time.

One builds the facility.

The other builds the organization capable of operating it.

That means identifying the team early, developing greenhouse management skills, creating SOPs, involving operators in commissioning, establishing clear responsibilities and continuing technical support through the transition into commercial production.

Because ultimately, the value of sophisticated greenhouse technology depends on what happens after everyone involved in construction leaves the site.

The question is not only, “Can we build it?”

It is, “Can the organization operate it successfully every day after we do?”

At NuLeaf Farms, we approach greenhouse and indoor farm development as an integrated process—from feasibility and project planning through system design, automation, commissioning, operator training and long-term operational optimization.

Planning a Greenhouse or Indoor Farm? Build Operational Readiness Into the Project.

A successful greenhouse project does not end when construction is complete.

NuLeaf Farms helps greenhouse and indoor farming projects move from design and construction into successful operation through system integration, commissioning, operator training, SOP development, automation, and ongoing operational support.

By preparing the people, processes, and technology together, operators can enter production with a clearer understanding of how the facility should run—and how to respond when conditions change.
