We control two different artificial lighting systems per greenhouse.
Activation by fixed time or at dawn/sunset. Up to two per day.
Activation by sum of light. We prolong the length of the day making use of the artificial lighting until reaching the programmed Klux level.
Activation by hours of light. We predict when the artificial light should be turned on to ensure that the plant receives the programmed hours of light.
We activate light intermittently.
Registering the working time for each lamp allow us to know when the lamps should be replaced.
