The OMAFRA Greenhouse Vegetable Specialist is continuing an exciting webinar series on technology in controlled environments!
This series is relevant to anyone producing in controlled environments – from vegetables, to herbs, cannabis and flowers. The second webinar tackles the use of black out curtains for light abatement in these systems, and how their use can impact plant production. Industry experts from AAFC, Hoogendoorn, Ludvig Svensson, Van der Ende Group and 360 Energy are all participating. so don’t miss the opportunity to hear from so many experts at once! This webinar covers each company’s approach to addressing challenges of production under curtain cover, and involves a panel-style discussion about integrating these systems.
Details on this installment of this webinar series can be found below.

Description: The use of supplemental lighting in greenhouse agriculture has greatly increased in recent years. Producers are using high pressure sodium (HPS), light-emitting diodes (LEDs), and other types of lights to extend their production season. This has been accompanied by the need to use light abatement/blackout curtains to reduce light emissions from greenhouses during night-time hours. Light abatement/blackout curtains can change the greenhouse environment in a number of ways when the lights are on and plants are undergoing photosynthesis and respiration. For example, greenhouse humidity and temperature can be greatly affected depending on the types of lights being used and the crop being grown. Managing the proper use of light abatement/blackout curtains in conjunction with supplemental lighting poses a challenge for producers. The objective of this webinar is to present greenhouse producers with information about different technologies available to them to manage the greenhouse environment when using blackout curtains and supplemental lighting. Speakers that specialize in different aspects of greenhouse environment management, such as curtain management, air-mix fans, heating and cooling, and overall energy management will present their strategies. This will be followed by a panel-style discussion to address questions from producers.
