  • 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...
  • 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.

  • 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...
  • 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...
  • 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...
