  • Here is presentation given by Dutch consultants on the 29th January. Growers who attended this event heard how the drive to save energy, and to grow more sustain-ably, was seeing fundamental changes to glasshouse cropping practices in the Netherlands.
  • The graph below shows energy use over the course of a day in February at R&L Holts (one of the GrowSave Focus Nurseries). It is a perfect illustration of how things should operate when a thermal screen is set up correctly!
  • It is now well proven that retractable thermal screens can save energy without having a detrimental effect on plant growth or quality; and you might even argue that a screen is now also an essential tool for both energy saving and
  • The use of thermal screens has become common place on many edible crop nurseries. They've been shown to save large amount of energy, paying back their cost quickly. In 2005, HDC project PC 198 showed that a thermal screen could save 100 kWh/m2 p.
