  • Minimum pipe temperature set points are used to force heat into a greenhouse even if it is not required to maintain the required greenhouse temperature. This can be to: Help with humidity control Ensure heat stores are empty by sunrise to maximise CO2 enrichment during the daytime. 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...
  • Avoiding condensation on plants is a key part of any disease control strategy. Poinsettia growers have to pay particular attention to this problem as they use a technique to control plant height called ‘Drop’. ‘Drop’ involves reducing the greenhouse temperature to as low as 12 degrees C before sunrise and is followed by an increase in the greenhouse temperature to the daytime set point within one hour after sunrise. Read More...
  • One of the side effects of reducing energy consumption, or using biomass for heating, is that less carbon dioxide (CO2) is available for enrichment. So, can crops be grown with less CO2 without reducing yield? This is the question that researchers from Wageningen University are currently trying to answer. Read More...
