Energy efficiency is not just low-hanging fruit; it is fruit on the ground. Stephen Chu, US Secretary of Energy
  • 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.
  • Because supplementary lights also produce heat, they can have a sudden impact on the temperature balance of a greenhouse when they are turned on.
  • 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.
  • In this factsheet, Farm Energy Centre's Chris Plackett, and Steve Adams and Allen Langton from Warwick Horticultural Research International (HRI) highlight the benefits of good housekeeping — the first essential step in achieving efficient energy management.
  • 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.
  • In 2008, the GrowSave team worked with tomato growers R & L Holt to optimise the use of thermal screens at their Hornsfield Nursery. The end result was best practice energy use levels and enhanced crop yield.
