  • 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 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. For edible crop growers this is normally at the top of the crop whereas for ornamentals growers it is just above the crop canopy. Read More...

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.
