  • 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...
  • Because supplementary lights also produce heat, they can have a sudden impact on the temperature balance of a greenhouse when they are turned on. Get your control strategy right and the ‘waste heat’ from the lights can make a useful contribution to the heating needs of the greenhouse. Read More...
  • In our article 'Where should you position your measuring box?', we showed how relying on a measuring box placed in the traditional position at the top of a tomato crop can give non-optimised control of the greenhouse environment and lead to wasted energy. Read More...
  • 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...
  • Controlling humidity can be expensive in energy terms, yet it is essential for the control of fungal disease and to ensure active plant growth. Humidity control also needs to be carefully targeted so as not to negate the energy savings from measures such as temperature integration (TI) and thermal screens. Read More...
