  • What are the energy implications of using ‘pre-night’ or ‘drop’? ‘Pre-night’ is a technique used by some edible crop growers who believe that a rapid drop in greenhouse temperature just before sunset helps crop development. Read More...
  • 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! (Click on the graph to see a larger version)                     Read More...
  • Reducing minimum pipe temperature settings is a good way to save energy. However, this must be done alongside well considered ventilation settings to ensure that heating requirements are minimised. The example below shows what happened at one of our Focus Nurseries where humidity influences and minimum ventilation settings were reducing the effect of a good minimum pipe temperature strategy.

  • 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. Read More...
  • 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 greenhouse environment optimisation. Read More...
