A nation that can't control its energy sources can't control its future. Barack Obama
  • At the end of February 2014, twenty growers and horticultural industry professionals from the UK visited Ontario and British Columbia on a greenhouse horticulture study tour, organised by the GrowSave team. The group visited 14 organisations which comprised of nurseries, R&D facilities and industry suppliers.
  • There is increasing evidence that using diffuse light within a greenhouse can give production advantages, such as an increase in yields and reduced time to market, as well as quality improvement.
  • 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!
  • In our article 'Optimising screen and vent control with lights',  we explained the importance of gapping when
  • 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.
  • In this factsheet, Farm Energy Centre's Chris Plackett, and Steve Adams and Allen Langton from Warwick Horticultural Research International (HRI) outline how efficient thermal screens can save energy in glasshouse production without adversely affecting yield or quality.
  • 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
