DutchGreenhouses designs, engineers and delivers turnkey greenhouse projects worldwide. HQ: Europa 1, 2672 ZX, Naaldwijk, NL. Content is written by Timo Raus and technically reviewed by our engineers. ## Pages - [Home](https://dutchgreenhouses.com/index.md): High-tech greenhouse facilities, engineered for the visitor's climate using recent NASA data. - [About DutchGreenhouses](https://dutchgreenhouses.com/about-dutchgreenhouses.md): DutchGreenhouses is an internationally oriented greenhouse manufacturer from the Netherlands, exporting Dutch technology and knowledge worldwide. - [Approach](https://dutchgreenhouses.com/approach.md): 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.md): 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.md): 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.md): 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): With the vents shut on a bright morning, CO2 inside a greenhouse can fall below outdoor levels. Dosing from CHP flue gas or liquid CO2 puts it back. - [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.md): 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.md): 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.md): Flowers, vegetables and indoor produce: crop-specific greenhouse cultivation, backed by training, education and coaching. - [Disclaimer](https://dutchgreenhouses.com/disclaimer.md): Disclaimer for the DutchGreenhouses website covering content accuracy, liability and intellectual property. Consult our team for project-specific advice. - [Flowers](https://dutchgreenhouses.com/flowers.md): Flower cultivation in high-tech greenhouses: photoperiod steering, screening and climate control tuned per variety. - [General Terms](https://dutchgreenhouses.com/general-terms.md): General terms of DutchGreenhouses B.V., applicable to all offers, agreements and deliveries: quotations, delivery, warranty, liability and payment. - [Greenhouse Construction](https://dutchgreenhouses.com/greenhouse-construction.md): Greenhouse structure and construction: steel and aluminium frames, Venlo and semi-closed types, glass covering and the service building that comes first. - [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): Within a crop’s usable range, roughly every extra percent of light returns a percent of yield. How diffuse, clear, coated and panel coverings compare. - [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. - [Ventilation Mechanism](https://dutchgreenhouses.com/greenhouse-construction/ventilation-mechanism.md): Roof ventilation mechanisms: motor-driven opening windows that exchange air, dump heat and manage humidity — the first climate tool. - [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.
