Online workshop : learnings from the low-energy input trial for greenhouse tomatoes

Online workshop : learnings from the low-energy input trial for greenhouse tomatoes
If you are not a tomato grower or you do not grow with lights, the approach to energy saving is also transferable to your situation.

When: Monday, 13th October
Time: 7 pm
Run by: Tico van Leeuwen, with Andy Lee leading the discussion both from Grodan.

About: The discussion will focus on a collaborative research project between Grodan and Philips Horticulture LED Solutions. Our aim was to reduce total heat input into a full LED-lit tomato crop by>40%.  So what’s the dilemma? In winter, when you have a minimum radiant heat input from the sun combined with energy-efficient LED lights, how can you work with lower pipe temperatures, stimulate sufficient plant transpiration and nutrient uptake, whilst at the same time control greenhouse humidity?  The answer is you have to do something that’s not been done before, you have to set a vision for the new ‘norm’.  We shall talk about how we overcame our dilemma and achieved >50% lower heat input compared to a reference tomato grower with the same variety over two years of trials.  If you are not a tomato grower or you do not grow with lights, the approach to energy saving is also transferable to your situation.

What Tomato, Cucumber, Capsicum and Capsicum Growers Need to Know (And other heated greenhouse crops). Energy has shifted from a manageable operating cost to a strategic production risk for New Zealand’s protected-cropping sector. In 2025, growers are facing a convergence of structural changes that directly affect whether heat is available when it is needed, not just what it costs.
