X-PHOTO : X-PHOTO controller permits the automatic activation of an artificial lighting system in a greenhouse (photosynthesis and photoperiodism). Two daily artificial lighting periods are programmable with a starting time and ending time: the first (day period) can be used for assimilation lighting; the second (night period) for photoperiodism. The first period is used to extend the daylight, when it’s insufficient for the right growth of the plants. The controller is equipped with light sensor: the light level to switch on/off the lamps is programmable.

The second period is used during the night for photoperiodic cycles.
