The right lighting
To get the right lighting, they installed a hybrid system comprising Philips GreenPower LED interlighting modules in two rows (delivering 110 μmol/m2/s) and Philips GreenPower LED toplighting modules (delivering 112 μmol/m2/s). Installation was managed in co-operation by Philips LED Horti Partner Agrolux and LS Systems UK Ltd.
The results are promising. After two days of lighting the tomato plants already looked stronger, with darker leaves, more purple anthocyanin in the head, and a stronger truss. Flavourfresh expects to increase yield of the tomato crop by a minimum of 30% with LED technology.
The hybrid LED top/interlighting system makes it possible for growers with low-ceilinged greenhouses to keep the lighting on during winter. Without the negative effect of heat radiation, the greenhouse retains more C02, which will lead to higher production.
