  • 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...
  • 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...
  • Reducing minimum pipe temperature settings is a good way to save energy. However, this must be done alongside well considered ventilation settings to ensure that heating requirements are minimised. The example below shows what happened at one of our Focus Nurseries where humidity influences and minimum ventilation settings were reducing the effect of a good minimum pipe temperature strategy.

  • 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.

  • In recent years, the accepted norm for growers of edible crops such as tomatoes, cucumbers and peppers has been to control humidity based on humidity deficit (HD). This is because conventional wisdom suggests that maintaining a minimum HD promotes transpiration, which, in turn, ensures optimised plant development and growth. Read More...
