An industrial greenhouse without engineering systems is just a frame with a covering. The yield, the timing of production and the running costs are determined not so much by the structure as by what is installed inside it. Heating, ventilation, irrigation, climate control — each system solves a specific task and directly affects the economics of the project.
Below we look at which engineering systems an industrial greenhouse needs, what determines the set and how to select the package for the type of structure, the crop and the region.
Why an industrial greenhouse does not work as a business tool without engineering systems
The task of an industrial greenhouse is to provide predictable growing conditions regardless of the weather outside. Temperature, air and soil humidity, light level, CO2 content — all these parameters have to stay within the set range. A deviation in any of them leads to lower yield, worse product quality or direct losses.
Without a heating system the greenhouse becomes a seasonal facility that stands idle for 4–6 months a year. Without automatic irrigation it is impossible to keep to a nutrition regime on areas from 1,000 m². And without ventilation, summer overheating can destroy the planting within a few days.
The engineering package is decided at the design stage and determines whether the complex will work as controlled production or as an expensive hothouse with unpredictable results.
Basic engineering systems of an industrial greenhouse
Three systems make up the mandatory minimum for practically any commercial project. Full operation of a greenhouse complex is impossible without them.
Heating
The heating system determines how many months a year the greenhouse will work. For year-round growing in central Russia and further north heating is mandatory. In southern regions it is needed at least to protect against spring and autumn frosts.
The type of equipment is selected for the available energy source — gas, coal, pellets or electricity. Water heating with distribution by circuits remains the most common solution: even warming across the whole area and the ability to zone the temperature regime for different crops.
Heating accounts for a significant share of operating costs. At the design stage it is important to calculate the heat losses for the type of covering: Venlo glass greenhouses lose less heat thanks to their air tightness, while film structures compensate for heat losses with an inflation system and energy-saving screens.
Ventilation and air circulation
Ventilation performs two tasks: it removes excess heat in hot weather and provides an inflow of fresh air with the carbon dioxide needed for photosynthesis.
Several types of ventilation are used in industrial greenhouses. Ridge ventilation works through vents in the upper part of the roof that open automatically as the temperature rises. Side ventilation works through roll-up walls or hinged vents around the perimeter. A combination of both creates a natural draught that renews the air efficiently without forced blowing.
Circulation fans even out the temperature across the area. Without them the air at the ridge is 5–8 degrees warmer than at ground level, which leads to uneven plant development. Mixing the air layers reduces the risk of local overheating and overcooling.
Automatic irrigation
Manual watering on areas from 1,000 m² is uneconomical: it means dozens of man-hours a week, uneven moistening and no way to control water and fertiliser consumption precisely.
Drip irrigation with fertigation is the standard for industrial greenhouses. Water and nutrient solution are delivered directly to the root zone of each plant. Water consumption falls by 30–50% compared with overhead irrigation, and precise fertiliser dosing makes it possible to manage the crop at every stage of growth.
Irrigation control is linked to substrate moisture and solar radiation sensors. An automated system removes the human factor and provides a stable nutrition regime regardless of the qualifications of the staff.
Systems that improve control and efficiency
Beyond the basic set there are systems that turn a greenhouse from a functional building into a highly controlled production facility.
Climate control brings heating, ventilation, irrigation and supplementary lighting together on a single platform. The controller receives data from temperature, humidity, light and CO2 sensors and adjusts the systems in real time. For complexes from 1 ha it is a necessity — manual control over such areas is physically impossible.
The screening system has a double function. In winter the retractable screens reduce heat losses through the covering by 30–50%, cutting heating costs. In summer the same screens shade the plants from excess solar radiation.
The drainage system removes excess moisture from the root zone. In substrate growing the drainage collects surplus nutrient solution for reuse, reducing water and fertiliser consumption.
Growing gutters provide the correct slope for the drainage to run off, organise the working space and make crop work easier.
Electrical systems — power distribution for the heating equipment, vent drives, pump stations, controllers and supplementary lighting. The power supply design is developed in parallel with the engineering part and determines the required connected capacity.
Which systems matter most for film greenhouses
Industrial film greenhouses have a number of structural features that affect the choice of engineering equipment.
The inflation system — blowing air between two layers of film — creates an air cushion that improves the thermal insulation of the covering and reduces heating costs. For year-round operation in regions with cold winters inflation is practically mandatory.
The large internal volume with a gothic roof shape works as a microclimate buffer — the air mass heats and cools more slowly, smoothing out daily swings. But managing that volume requires correct ventilation: a combination of side and ridge vents with sufficient opening area.
Circulation fans are especially important here. A ridge height of 5–6 metres creates pronounced stratification, and without forced mixing the temperature difference between the upper and lower zones reaches 8–10 degrees.
How to select the package for the type of greenhouse and the crop
The package is determined by the crop, the region, the seasonality and the budget. Below are indicative scenarios for typical tasks.
| Scenario | Type of greenhouse | Mandatory systems | Recommended additions |
| Tomatoes, cucumbers (all year) | Venlo or film | Heating, ventilation, drip irrigation with fertigation, climate control | Supplementary lighting, screening, CO2, drainage |
| Leafy greens, lettuce (extended season) | Film | Heating (basic), ventilation, irrigation | Climate control, circulation fans |
| Berries (seasonal) | Tunnel or film | Ventilation, drip irrigation | Drainage, shade screens |
| Seedlings (spring–summer) | Film | Heating (spring), ventilation, irrigation, fogging | Climate control, screening |
| Flowers (all year) | Venlo | Heating, ventilation, irrigation, supplementary lighting, climate control | Screening, CO2, growing gutters |
The specific set of equipment is calculated individually — two complexes of the same area in the Krasnodar Region and the Leningrad Region will require fundamentally different engineering.
How to request a package selection
The engineering systems of an industrial greenhouse are a balance between a stable microclimate and reasonable operating costs. An excessive package increases the budget without a proportional return; an insufficient one puts the crop and the profitability at risk.
Send a request on the NIVA GREENTECH website — our specialists will select the package for your crop, area and region. The company has been designing and building turnkey greenhouse complexes at its own plant since 2007. Examples of completed projects: a 12 ha propagation centre in the Krasnodar Region, a Venlo glass greenhouse in Uzbekistan.
FAQ
Can climate control be done without?
On areas up to 500–1,000 m² an experienced agronomist can manage the microclimate manually. On commercial facilities of 1 ha and above automated climate control is essential — manual control provides neither the precision nor the speed of reaction to changing conditions.
Which systems are installed first?
Heating, ventilation and automatic irrigation. This is the minimum without which an industrial greenhouse cannot function as a production facility. The other systems are added depending on the tasks and the budget.
What affects the engineering budget most?
The heating system and climate control. Together they can account for 40–60% of the cost of the engineering package. The exact share depends on the region, the area and the target crop.
Which systems are needed all year round?
Irrigation works throughout the growing period. Heating runs from autumn to spring, and occasionally in southern regions. Ventilation works all year, but with varying intensity. Climate control and screening work constantly, if installed.
How does the engineering of a Venlo differ from a film greenhouse?
A Venlo has higher air tightness and a higher level of automation, which allows more precise microclimate control. Film greenhouses are additionally fitted with an inflation system and require more powerful ventilation.
Can the engineering of an existing greenhouse be upgraded?
Yes. Supplementary lighting, climate control and automation can be installed in a working complex, although an upgrade costs more than building the systems in at the construction stage.
Is supplementary lighting needed?
It depends on the crop and the region. For year-round growing of tomatoes and cucumbers north of the 50th parallel supplementary lighting noticeably increases winter yields. For seasonal production it is not required.
