Modifying the climatic steering by using temperature integration (IT) over 24 hours is one of the ways of realising energy saving in greenhouse crops. A trial conducted from 2007 to 2009 in soilless gerbera crop showed that about 15 % energy saving for the whole crop was possible. The yield in number of stems per square metre, the stems development rate as well as the vase life duration were not influenced by the IT steering. However, the stems were slightly shorter with IT. Regarding the phytosanitary aspects, the IT had no effect on the development of predatory mites (Typhlodromips swirskii, Amblyseius cucumeris) nor on this of powdery mildew. There was less whitefly pressure in the IT greenhouse. The results confirm that temperature integration is a useful method to save energy in soilless gerbera crop without yield and quality losses.
