Light is not all the same, especially for plant growth. This topic will be discussed at Macfrut during the convention (Friday 12th May, 11 am, meeting area D3) organised by Ambra Light (hall D7, stand 197). The event will also be attended by Milena Mastropierro from Migreen Food, a company from Puglia producing microgreens.
"We started our studies on LED lights 5 years ago and immediately began collaborating with the University of Padua to follow a precise protocol," explains spokesman Stefano Pizzolato.
The principle is simple: plants use a certain range of the spectrum for photosynthesis. We supply light part of that range, so as to provide the maximum efficiency while reducing consumption. Producers have reported cycles up to 5 days shorter and energy savings up to 50%."
"I would like to stress that we use Italian technology and we don't just assemble material from Asia. We work in partnership with Osram. The LED technology provides more light while consuming less. The initial investment is higher than with traditional lamps but savings and efficiency make up for it in a short amount of time."
The photosynthetic process needs precise red and blue frequencies. The human eye perceives them as fuchsia, which is often seen in greenhouses and microgreen crops. But it's not that simple: slightly different "mixes" are needed according to the phenological phase to stimulate and this is where Ambra Light engineers become especially important.
"Light must be dosed, especially if it needs to be distributed uniformly. Generally, LEDs are located 2.50 metres above the ground in greenhouses and 30-40 cm high in shelf crops. Of course specific plans are needed for each situation, types of cultivation and objectives to reach."
