Abstract The use of low intensity red or far-red LED light during the dark period was tested in a commercial greenhouse at Akerboom Freesia. The use of red or far-red light in the dark period had no clear effect in Freesia. The production of the variety ‘Ambiance’ increased 6% at 8 μmol.m-2.s-1 red LED light during the dark period, but there was no increase in production for the variety ‘PinkPassion’. Low intensity far-red during the night period did not give an increase in production. It was shown that it is possible to realise a good Freesia production in a greenhouse with a lower intensity assimilation lighting. This was in combination with a lower temperature which resulted in a longer growing period compared to the cultivation of Freesia in a greenhouse with a higher intensity assimilation lighting and higher temperature.
