## Pages

- [Home](https://dutchgreenhouses.com/): High-tech greenhouse facilities, engineered for the visitor's climate using recent NASA data.
- [About DutchGreenhouses](https://dutchgreenhouses.com/about-dutchgreenhouses): DutchGreenhouses is an internationally oriented greenhouse manufacturer from the Netherlands, exporting Dutch technology and knowledge worldwide.
- [Approach](https://dutchgreenhouses.com/approach): What to grow, where to grow and how to grow — every DutchGreenhouses project starts with data, then becomes a turnkey greenhouse.
- [How to grow](https://dutchgreenhouses.com/approach/how-to-grow): Hardware plus knowledge: training, education and coaching alongside the greenhouse — that combination makes an operation succeed.
- [What to grow](https://dutchgreenhouses.com/approach/what-to-grow): Crop selection is the first feasibility question: market demand, crop economics and climate fit decide what your greenhouse should grow.
- [Where to grow](https://dutchgreenhouses.com/approach/where-to-grow): Location determines greenhouse design: three years of climate data decide which systems your facility needs and what it will cost to operate.
- [Automation](https://dutchgreenhouses.com/automation.md): Greenhouse automation: climate computers, internal logistics and labour automation — one control layer from sensor to strategy.
- [Climate](https://dutchgreenhouses.com/climate.md): Greenhouse climate systems: heating, cooling, humidity control, HortiCoolers and CO2 enrichment — the growing climate under control.
- [Climate Zones](https://dutchgreenhouses.com/climate-zones.md): The same Venlo bay behaves differently at 52 degrees north than at 24. Climate zone changes the glass, the screens, the cooling strategy and sometimes the whole structure.
- [Arid & Desert](https://dutchgreenhouses.com/climate-zones/arid-desert.md): Cooling dominates, and every cooling method that works here spends water — in the place with the least of it. That trade decides the whole design.
- [Cold Extreme & Polar](https://dutchgreenhouses.com/climate-zones/cold-extreme.md): Where daylight, not temperature, is the binding constraint. Lighting stops being supplemental and becomes the primary production system.
- [Continental](https://dutchgreenhouses.com/climate-zones/continental.md): Hard winters and hot summers in one location. Snow and wind load set the steel before anything else is chosen, and the house needs both heating and cooling.
- [High-Altitude Tropical](https://dutchgreenhouses.com/climate-zones/high-altitude-tropical.md): Equatorial light with cool nights and a twelve-hour day all year. It is why the world’s cut flowers come from Kenya, Ethiopia and the Bogotá savanna.
- [Mediterranean](https://dutchgreenhouses.com/climate-zones/mediterranean.md): Mild winters and hot summers tempt growers into cheap unheated houses. Unheated is not the same as uncontrolled, and the winter nights are where that shows.
- [Temperate Maritime](https://dutchgreenhouses.com/climate-zones/temperate-maritime.md): Mild, grey and damp. The binding constraint is winter light, not winter cold — which is why the Dutch model is built around glass, screens and lamps.
- [Tropical & Humid](https://dutchgreenhouses.com/climate-zones/tropical-humid.md): Ventilation only removes moisture if the outside air can carry it. In saturated tropical air there is no gradient, so opening the vents achieves nothing.
- [CO2 Enrichment](https://dutchgreenhouses.com/climate/co2-enrichment.md): CO2 enrichment raises photosynthesis directly: dosing from CHP exhaust or liquid CO2, computed against ventilation losses.
- [Cooling](https://dutchgreenhouses.com/climate/cooling.md): Greenhouse cooling: ventilation, screens, adiabatic pad-and-fan and mechanical systems — matched to how hot your summers get.
- [Heating](https://dutchgreenhouses.com/climate/heating.md): Greenhouse heating: pipe-rail systems, hot water buffers and CHP integration keep the crop warm at the lowest energy cost.
- [HortiCoolers](https://dutchgreenhouses.com/climate/horticoolers): HortiCoolers deliver active cooling and dehumidification for greenhouses in hot climates — growing where ventilation alone fails.
- [Humidity Control](https://dutchgreenhouses.com/climate/humidity-control.md): Humidity control manages VPD, transpiration and condensation risk — dehumidification, ventilation and screen strategy combined.
- [Contact](https://dutchgreenhouses.com/contact): Get in touch with DutchGreenhouses to plan your turnkey greenhouse project. Tell us your crop, location and scale for a climate-matched proposal and budget.
- [Controlled-Environment Agriculture](https://dutchgreenhouses.com/controlled-environment-agriculture.md): Controlled-environment agriculture (CEA): growing inside a structure whose conditions are specified rather than observed — and where a project should sit on that spectrum.
- [Crop Protection & Hygiene](https://dutchgreenhouses.com/crop-protection.md): Crop protection in a greenhouse is a containment problem, not a spraying problem — prevention, monitoring and threshold-based intervention under the EU’s eight IPM principles.
- [Hygiene Protocol](https://dutchgreenhouses.com/crop-protection/hygiene-protocol.md): Pathogens arrive on hands, tools and footwear more reliably than through any engineered route. Cleaning is not disinfecting, and no chemical fully sterilises a growing system.
- [Integrated Pest Management](https://dutchgreenhouses.com/crop-protection/integrated-pest-management.md): IPM exists because the chemistry runs out. The EU’s eight principles put prevention, monitoring and threshold decisions ahead of intervention — and biology ahead of chemistry.
- [Pollination](https://dutchgreenhouses.com/crop-protection/pollination.md): Bumblebee hives replace hand pollination in fruiting greenhouse crops — and a colony living in the crop constrains every product applied for the whole season.
- [Scouting & Monitoring](https://dutchgreenhouses.com/crop-protection/scouting-monitoring.md): A threshold you cannot measure is not a threshold. Sticky traps, fixed scouting rounds and digital mapping turn observation into the counts every IPM decision depends on.
- [Cultivation](https://dutchgreenhouses.com/cultivation): Flowers, vegetables and indoor produce: crop-specific greenhouse cultivation, backed by training, education and coaching.
- [Disclaimer](https://dutchgreenhouses.com/disclaimer): Disclaimer for the DutchGreenhouses website covering content accuracy, liability and intellectual property. Consult our team for project-specific advice.
- [Flowers](https://dutchgreenhouses.com/flowers): Flower cultivation in high-tech greenhouses: photoperiod steering, screening and climate control tuned per variety.

- [Aluminium System](https://dutchgreenhouses.com/greenhouse-construction/aluminium-system.md): The aluminium super-structure: gutters and glazing bars that carry glass, drain rainwater and stiffen the greenhouse as structural elements.
- [Foundation](https://dutchgreenhouses.com/greenhouse-construction/foundation.md): Greenhouse foundations: boreholes, perimeter tie-beams and prefabricated steel posts — lightweight where possible, piled where required.
- [Greenhouse Glass Covering](https://dutchgreenhouses.com/greenhouse-construction/greenhouse-glass-covering.md): Glass, polycarbonate or sandwich panels: covering choices that balance light transmission, insulation and diffusion per climate.
- [Insect Netting](https://dutchgreenhouses.com/greenhouse-construction/insect-netting.md): Insect netting on ventilation openings keeps pests out while air keeps flowing — installed as the final step of construction.
- [Rainwater Collection](https://dutchgreenhouses.com/greenhouse-construction/rainwater-collection.md): The greenhouse roof as water system: V-shaped roofs discharge into integrated gutters, feeding rainwater basins for irrigation.
- [Service Building](https://dutchgreenhouses.com/greenhouse-construction/service-building.md): The service building houses technology, logistics and staff — built first so installations and storage can start on time.
- [Steel Structure](https://dutchgreenhouses.com/greenhouse-construction/steel-structure.md): The greenhouse steel sub-structure: columns, trusses and facade girts calculated per load zone, hot-dip galvanized for a long lifespan. No purlins — no steel runs horizontally in a Venlo roof.

- [Greenhouse Horticulture](https://dutchgreenhouses.com/greenhouse-horticulture.md): Greenhouse horticulture is controlled-environment agriculture where sunlight stays the primary light source and the structure’s job is to trap, transmit and manage it.
- [Glass Greenhouse](https://dutchgreenhouses.com/greenhouse-horticulture/glass-greenhouse.md): The glass greenhouse: highest light transmission of any covering, optics that hold for decades, and the structural class that a rigid cladding forces on the steel.
- [Semi-Closed Greenhouse](https://dutchgreenhouses.com/greenhouse-horticulture/semi-closed-greenhouse.md): A semi-closed greenhouse conditions its air instead of exchanging it. Air handling units on the sides and HortiCoolers cool, heat and dehumidify with the vents shut — so the CO2 stays in.

- [Performance & Outcomes](https://dutchgreenhouses.com/performance.md): What a greenhouse buyer is actually purchasing: yield, light transmission, energy use, water circularity, carbon footprint and security of supply — each with the metric it is measured by.
- [Carbon Footprint](https://dutchgreenhouses.com/performance/carbon-footprint.md): Dutch greenhouse cultivation emitted around 37 kg CO2 per square metre in 2024, against a binding 2030 residual target of 4.3 Mton for the sector.
- [Year-Round Production](https://dutchgreenhouses.com/performance/climate-resilience.md): A field gives you a season. A greenhouse gives you a date. Growing to a contract instead of a harvest is what makes a project financeable.
- [Energy Use](https://dutchgreenhouses.com/performance/energy-use.md): Dutch greenhouse energy use runs near 1 GJ per square metre per year, temperature-corrected. The heating design, the screen package and the lighting choice each move that number.
- [Light Transmission](https://dutchgreenhouses.com/performance/light-transmission.md): Light transmission is the share of outside light reaching the crop, and within a crop’s usable range a percent of light is a percent of yield — decided once, at design time.
- [Water Use & Circularity](https://dutchgreenhouses.com/performance/water-use.md): Dutch substrate greenhouses recirculate roughly 90 to 100 percent of drain water. Sodium, not disinfection, sets how closed the loop can actually be.
- [Yield](https://dutchgreenhouses.com/performance/yield.md): Greenhouse yield is measured in kilograms per square metre per year, and cultivar sets the range before any technology does — from 28 kg/m² for cherry tomatoes to 90 for beef.
- [Privacy](https://dutchgreenhouses.com/privacy): Privacy statement: how DutchGreenhouses handles personal data, including the IP-based climate personalization on this website.
- [Screening](https://dutchgreenhouses.com/screening.md): Greenhouse screening: energy, blackout and diffuse screens that modulate light, radiation, humidity and energy use.
- [Blackout Screens](https://dutchgreenhouses.com/screening/blackout-screens.md): Blackout screens give full photoperiod control for light-sensitive crops and block light emission to the environment.
- [Diffuse Screens](https://dutchgreenhouses.com/screening/diffuse-screens.md): Diffuse screens scatter direct sunlight deeper into the crop canopy, preventing scorch while raising photosynthesis.
- [Energy Screens](https://dutchgreenhouses.com/screening/energy-screens.md): Energy screens reduce greenhouse heat loss by up to 47%, modulating infrared radiation, daylight and air movement.
