European Study Shows Diffused Light Increases Plant Growth Rate
In recent trials at the Netherlands Wageningen UR (WUR) Greenhouse Horticulture, researchers found producing pot plants under a light-diffusing screen shortens the production time by 25 percent and results in better-quality plants. Anthurium pot plants produced in light-diffused greenhouses equipped with Svenssons Harmony screens were ready for sale at 16 weeks compared to the normal 22 weeks, said Leo Marcelis, lead researcher of the WUR. The trials also included bromeliad varieties, with finished products ready two to four weeks early. Researchers structured trials with anthuriums and bromeliads in separated greenhouses, each approximately 1,615 square feet. The two greenhouses with Harmony light-diffused screens had light treatments of 10 moles of photosynthetically active radiation (PAR) per day and 7.5 moles PAR per day. Each was equipped with Svensson energy curtains, and misting systems provided relatively high humidity levels. In addition to increased growth rate, quality was also improved, with plants in the 10-mole greenhouse 25 percent heavier than typical.
