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.
  • Although the flue gasses from a biomass boiler are rich in carbon dioxide, they must be cleaned before they can be used for greenhouse enrichment. A system that does this is the ProSelect GC6, and the only nursery worldwide using the equipment is in Vancouver, Canada.
  • 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.
  • In our latest technical update we take a look at how air movement systems can improve the greenhouse environment and contribute to:
  • 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.
  • Because supplementary lights also produce heat, they can have a sudden impact on the temperature balance of a greenhouse when they are turned on.
  • 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.
