Strawberry tests back B100 LEDs for growth

Valoya B100 LEDs have beaten both high-pressure sodium (HPS) lights and LEDs from a large multinational company in daylight-free strawberry-growing trials, according to the Finnish supplier.

The tests on wild strawberries at the University of Helsinki led by researcher Dr Timo Hytonen found the Valoya lights induced stronger vegetative growth and flowering one week earlier than those under HPS lights. They also provided an environment in which staff could more easily monitor fruiting compared with the blue/red light from the rival firm's LEDs.

Unusually for LEDs, the B-series units emit light at a tailored range of wavelengths over a wide spectrum. The company explained that the lights can be positioned close to the crop because they emit no heat.
