Energy efficiency was not the main goal to install LEDs for the Imereti Greenery, because electricity is very affordable in Georgia. Greenhouses can become very warm in this climate, even during darker periods, like early spring and late autumn, so the challenge was to maintain a consistent temperature. Therefore the nursery needed something cooler than the toplighting provided by HPS.
That is why Dirk Aleven and Dick de Jong decided to go with RYGH LED toplighting. “Now we still have extra light in dark months, but without the very unwanted extra heat package coming along with that”, Dick explains.
When required due to agro processes, to keep energy costs down, the greenhouse uses geothermal energy for the ‘free-of-charge’ heat. LED grow lighting provides effective year round lighting in this warm climate, producing significantly less heat than conventional HPS lamps, so the greenhouse climate can be controlled more accurately. Less heat also means the Imereti Greenery can use light more effectively, for example by increasing led grow light levels, extending lighting periods, or by using light on warmer days without having to ventilate.
