  • In this Technical Update, we take a look at how air movement systems can improve the greenhouse environment and contribute to reduced energy costs, more even crops, and reduced disease risks. The update looks at fan systems and explains how apex screens can reduce unwanted natural air movement above thermal screens. Read More...
  • A GrowSave training day led by Tim Pratt and Jon Swain from Farm Energy Centre, held at Bordon Hill Nurseries in Warwickshire. The training was aimed at ornamentals growers — particularly those who grow energy-intensive crops in late autumn and winter — with a focus on important energy issues to consider when setting up your nursery for the forthcoming season.

  • This Technical Update explores the concept of a semi-sealed greenhouse — looking at the system's advantages, its current commercial position, and how it compares with the completely-sealed greenhouse concept. Read More...
  • 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. With this in mind, the specialist growers Coletta & Tyson took the decision to save on energy costs by minimising their active humidity control. 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.
