Energy efficiency is not just low-hanging fruit; it is fruit on the ground. Stephen Chu, US Secretary of Energy
  • 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.
  • Common practice is to put measuring boxes in a position that is both practically convenient and which provides representative measurements of the conditions in the greenhouse.
  • Using heat to control humidity in a greenhouse gives the advantages of a good yielding and a disease-free crop. But with energy prices rising, many growers are left wondering whether humidity control is something they can really afford.
  • 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.
  • 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.
  • CO2 enrichment is vital to the cost-effective production of many glasshouse crops. However, it can have a high energy cost.
  • In our article 'Optimising screen and vent control with lights',  we explained the importance of gapping when
  • Common sense tells us that eliminating unnecessary venting will save energy. However, putting this theory into practice is not as simple as it sounds, especially when humidity control is a key requirement.
