Replacing HPS grow lights with LED grow light can promote plant growth faster and reduce farm energy consumption

An Italian Basil grower chose to replace high-pressure sodium lamps (HPS grow lights) with LED grow lights and found that it could promote plant growth and reduce farm energy consumption.

The grower, based in Reggio, Italy’s southern port, produces Basil for salads, pasta and other dishes. Previously, it had been using high-pressure sodium lamps in its greenhouse.

In order to avoid the typical Basil disease, growers use artificial grow light in the greenhouse for several hours a day, which increases the cost.

Using red, super red and blue LED lights in different proportions in the greenhouse can speed up the growth time of basil, shorten the harvest time by 5 days and increase crop yield.

Marco Boselli, manager of the planter, said, “we are worried about bacterial proliferation because peronospara fungus was eradicated by the heat generated by HPS grow lighting, but we didn’t encounter any problems after using led plant lights”.

“We can also observe that our Basil grows better and faster because the proportion of blue light is lower, which is 5% in the LED scheme, compared with 24% in the previous HPS scheme.”

Sebastian lyscic, global project manager of OSRAM optoelectronics, said: “durable, energy-saving and durable LED technology is becoming more and more popular and will one day replace standard gardening lighting.”
