Short answer: Commercial greenhouse operating cost should be estimated from crop cycles, labor, energy, water, fertilizer, seed or plants, substrate, crop protection, packaging, maintenance, replacement parts, logistics and management. There is no reliable universal cost per square meter because climate, crop, technology and local prices differ.
Fixed or semi-fixed costs may include permanent staff, insurance, software, security, land arrangements and scheduled service. Variable costs change with crop area, weather, production cycles or sales volume, such as energy, water, fertilizer, packaging and transport. Keep categories consistent so month-to-month data can be compared.
List managers, crop technicians, irrigation operators, maintenance staff, supervisors, harvest workers, packing labor and seasonal support. Estimate working hours for crop training, pruning, scouting, irrigation checks, cleaning, harvest, grading and dispatch. Automation can reduce selected tasks but does not remove the need for monitoring and skilled decisions.
| Energy user | Calculation input |
|---|---|
| Fans and pumps | Rated power, operating sequence, seasonal hours and motor efficiency. |
| Heating | Fuel or electricity source, climate requirement, efficiency and distribution system. |
| Cooling and fog | Fan, pad-pump or high-pressure-pump hours plus water demand. |
| Lighting | Fixture power, photoperiod strategy, seasonal use and electricity tariff. |
| Backup system | Generator test runs, fuel, service, batteries and expected outage operation. |
Use equipment schedules and realistic operating hours instead of multiplying greenhouse area by a generic energy factor.
Estimate raw water, treatment losses, irrigation, cleaning and evaporative cooling. Include filters, membranes, disinfectants and laboratory tests where used. Crop inputs may include fertilizer, acid or alkali, seed, seedlings, substrate, grow bags, clips, twine, beneficial organisms and approved crop-protection products. Recirculating systems may reduce discharge but add monitoring and sanitation tasks.
Create preventive-maintenance intervals for vents, gear motors, screens, fans, pumps, filters, dosing equipment, sensors, controls, gutters and drainage. Include lubricants, seals, belts, bearings, nozzles, emitters, probes and electrical components. Plan future replacement of film, nets, pads, substrate and other consumables based on actual specification, exposure and supplier guidance rather than an invented fixed life.
Include harvest containers, labels, cartons, trays, pallets, cooling, storage, quality losses, local transport and market delivery. Production economics can fail after the greenhouse if grading and distribution are not planned. Separate farm-gate costs from customer-delivered costs.
Track costs by month, crop cycle, greenhouse zone and saleable output. Compare water and energy per batch, labor per operation and packaging per unit sold. Do not hide unsold or rejected product when calculating cost. Use actual records to replace feasibility assumptions after startup.

There is no universal figure. Calculate from local prices, crop cycles, labor, systems, climate and operating hours.
It depends on local wages, climate systems, crop, automation and production schedule, so both require a project-specific model.
No. It changes water, fertilizer, labor, monitoring, sanitation, pumping and replacement requirements.
Update it with actual monthly and crop-cycle records and whenever tariffs, crop plans or equipment change.
Review the electrical load guide, maintenance checklist and water-quality guide.
