  • 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. Heating and ventilation set-points Well-developed plants and milder spring weather conditions mean that like most tomato growers, our Focus Nurseries now have an almost constant demand for humidity control.

  • When growing greenhouse crops, it’s sometimes desirable to use a little more heat than strictly necessary to maintain adequate growing conditions. The purpose of this is to keep conditions comfortably away from those which could, for instance, trigger a disease problem. 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.

  • It is now well proven that retractable thermal screens can save energy without having a detrimental effect on plant growth or quality; and you might even argue that a screen is now also an essential tool for both energy saving and greenhouse environment optimisation. Read More...
  • In our article 'Optimising screen and vent control with lights',  we explained the importance of gapping when screens are used over supplementary lights. But during spells of extreme cold weather, is it still correct for your screen to gap — and wouldn’t a fully closed screen help to save energy? Read More...
