Energy efficiency is a measure of energy used for delivering a given service. Improving energy efficiency means getting more from the energy that we use. DECC - Energy Efficiency Strategy: 'The Energy Efficiency Opportunity in the UK'
  • Jon Swain went on behalf of GrowSave to GreenTech, Amsterdam RAI to see what’s new and here are some photos and videos of what he found.
  • 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:
  • A presentation given by Farm Energy Centre's Tim Pratt at the TGA's 2013 Conference, on 26th September.
  • 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.
  • 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.
  • We all know that colder weather means we use more energy for greenhouse heating. But how do we know if any increases in energy use are just down to the weather, or perhaps to other factors making us less efficient? This is where a technique known as 'degree days' can help.
