Low-heat, full-LED trial on track to achieve higher yields and better quality in larger truss tomatoes

The mid-year results from the low-energy tomato trial initiated by Grodan and Philips Horticulture LED Solutions indicate that not only cherry tomatoes, but also larger truss tomatoes can be grown successfully with reduced heat input in a full-LED setup. Importantly, another major goal of this trial is to demonstrate to growers of Macxize XR (Axia seeds) how blotchy ripening (green spots), a troublesome potential quality issue in this high-yielding variety, can be reduced by adjusting the nutrient balance – specifically the potassium and nitrogen ratios.
Summary of mid-year results based on full LEDs, precision irrigation and active air dehumidification
Philips toplighting plus interlighting is on track to deliver 5-7% yield increase
Low-nitrate strategy supports generative plant steering
Adjusted potassium/nitrate ratios potentially lead to a reduction in blotchy ripening (green spots)
Fine-tuning of screening, heating and lighting strategies delivers additional energy savings
