In 'The Road to Digital Green Fingers' project, researchers increased the pre-night temperature in a tomato cultivation by one degree for four weeks. In this way, the crop was 'bullied' to see how far it could go, but especially also to understand the physiology behind the measurements. The better that…

Light is a crucial element for plant growth and production. High-pressure sodium (HPS) lamps are considered not very electrically efficient as they generate high radiant heat, and as a consequence, there has been a lot of interest in replacing HPS lamps with new more efficient lighting sources in the…

Greenhouse automation has come a long way in the past two decades. Give it another two decades, and it may completely overshadow the human element in the greenhouse. At least, that's a conclusion you might draw when looking at the results of the Autonomous Greenhouse Challenge and the implications of it…

In Autumn 2019 Gemüsebau Steiner installed Hyperion LED top lights in their tomato greenhouse in Kirchweidach, replacing the existing 1000W HPS fixtures with LED fixtures in an area of 5,000m2. This was the first 100% LED tomato installation in Germany. More importantly, this was a unique trial comparing…

“The current acreages dedicated to tomatoes in China are about 16 million mu, of which more than 9 million mu are for pink tomato, a main product that we breed. Currently, pink tomatoes in the north mainly face diseases where the whole plant becomes dead or where new leaves turn yellow. Against this…
