- FR_5 spectrum with far-red light encourages the stretching of some strawberry varieties in winter
- Two Belgian growers invest in full LED FR_5 with the GrowWise Control System for efficient, high quality winter cultivation
Eindhoven, the Netherlands – Signify (Euronext: LIGHT), the world leader in lighting solutions, introduces a new efficient LED light recipe with red, blue, green, and far-red light that has an added value for strawberry cultivation. The addition of far-red light to the usual red/blue spectrum encourages the stretching of stems and trusses in winter, allowing some varieties to use the available PAR light more effectively. Two Belgian growers have now equipped their new greenhouses with Philips LED GreenPower toplighting compact (TLC) grow lights with the new FR_5 spectrum.
The FR_5 spectrum contains red, blue, green, and far-red light. The far-red light provides more opportunities for strawberry growers – among others – to set up an efficient, high-quality winter production, or to optimize their existing production. Varieties that stretch less easily in the depths of winter with full LED without far-red light often do better with this new spectrum.
Plant specialist Peer Hermans of Signify says: “Little daylight is available in winter, and the lighting installation provides a large part of the total light sum. When the grow light contains too little far-red light some strawberry varieties can stay very compact. The leaves intercept less light and are quickly in each other’s way, at the expense of photosynthesis. Less stretching of the trusses also means that the fruits will not hang as low making the harvest more difficult. Furthermore, a more open crop produces a more favorable microclimate.”
