Dutch greenhouses
Just over 9,000 hectares of greenhouses — 0.2% of the country’s territory — and tomato yields 13 times the world average: glass, supplemental lighting, climate computers and water in a closed loop.




Numbers
- Greenhouses: just over 9,000 ha, ≈0.2% of the country’s area (2024).
- Tomatoes: 828.5 million kg from 1,726 ha — ≈48 kg per square meter a year (2024).
- Tomato yields: the Netherlands, 478.9 t/ha; the world, 36.8 t/ha (FAOSTAT, 2024).
- Switching from sodium lamps to LEDs cuts electricity purchases (WUR, 2024).
What to learn
Garden
Put seedlings under an LED grow light: short and sturdy, not leggy.
Farm
Even a film greenhouse with climate sensors and drip yields many times more than open ground.
Agribusiness
A climate computer, LEDs and recirculated water pay off: the money is in energy and in kilograms per square meter.
Video
A video search on third-party platforms — it opens in a new tab.
