In August 2018, Plessey announced that B4Hydrogrow BV, a new venture from B-Four Agro, a leading Dutch lettuce-grower, would be installing the new Hyperion 1750 micromole/s LED top lights in its first greenhouse measuring 29,000 m².
In recent years, B-Four Agro has developed into a specialist producer of lettuce, grown outdoors, mainly to supply the vegetable processing industry. The new glasshouse will mark a switch to indoor horticulture where lettuce will be produced hydroponically. B-Four Agro has tested hydroponic growing methods and is now investing, in a new greenhouse facility to be run under a new subsidiary company, B4Hydrogrow B.V.
B4Hydrogrow’s’s aim is to get the largest yield and the highest-quality lettuces from every square metre of growing space. To do this, it will invest heavily in automated production, an advanced growing system and 100% LED lighting. LEDs give off much less heat than SON-T lamps and are up to 40% more energy efficient, allowing a higher light level than would be possible using SON-T lamps. The specific wavelengths of light available with Plessey’s Hyperion grow light can result in a denser, more compact crop, with better colouration.
Commenting on his decision to choose Plessey’s new Hyperion LED grow light, B-Four Agro Director, Fred Berkhout said:
“When we looked at lighting for our new greenhouse project we decided to go with 100% LED as the most advanced, long term option. We wanted an LED lighting solution that offered flexible light spectrums, simple design, low shading and a good commercial return on investment. Plessey’s experience with their LEDs at lettuce grower Johan Desmet gave us confidence in the high quality of these lights.”
“Using LED lighting in lettuce growing is proven to be very successful, due to the fact that SON-T emits a lot of radiant heat”, says Plessey’s Head Agronomist, Maarten Klein, “This warms the plant temperature to levels which are unfavorable for quality and sturdy lettuce crops. With the use of the Hyperion LED, the grower can maximize production capacity by using artificial light in times when greenhouse temperature is critical.”
