Greenhouse LEDs found to speed up basil growth

Red, hyper red and blue LED light is used in different proportions in the greenhouse, a pattern that has been found to increase basil growth times.

A basil producer opted to replace high pressure sodium lighting with LEDs, which were found to boost plant growth whilst reducing the farm’s energy consumption.

Servizi Ambientali Bassa Reggiana (CEO of S.A.BA.R), based in the province of Reggio, which produces Italian basil for salad, pasta and other dishes, had, in the past used high pressure sodium lamps in their basil greenhouse.

To avoid typical basil illnesses, artificial light is often used for many hours per day in the firm’s greenhouses, pushing up costs.

Red, hyper red and blue LED light is used in different proportions in the greenhouse, a pattern that has been found to increase basil growth times.

In an attempt to tackle this an LED system was installed at the farm designed by Osram and Ambra Elettronica, using Oslon LED technology.

The new system reduced power consumption by 56 percent and dodged sending 30 tons of CO2 emissions into the atmosphere. The basil firm also reduced harvest times by five days and increased the crop production.

‘We were worried about proliferation problems because the peronospara fungus was previously eradicated by the heat generated by the HPS lighting, but we didn’t experience anything,’ commented Marco Boselli who is the CEO of S.A.BA.R.

‘We could also observe a better and faster growth of our basil due to the lower percentage of blue light, which is five percent with the LED solution compared to 24 per cent with our former HPS solution.’

‘Durable, energy efficient and long lasting LED technology is becoming more and more popular and will, one day, replace standard horticultural lighting,’ commented Sebastian Lyschic, global project manager at LED Light for You at Osram Opto.

  • A revolution is happening in horticulture. It’s a seismic shift that will change fundamentally how we grow plants, and it’s all down to lighting. Lux's Horticulture Lighting Conference will take place in Eindhoven, The Netherlands, on Tuesday 23 May 2017.
