iGrow1800 - Programming Lights - Daily Light Integral
The purpose of this option is to use artificial light, if necessary, to achieve a daily amount of accumulated light in the greenhouse zone.
Here is a video:
you will need a light sensor installed and mapped to accumulate your Light Values.
To program your output, simply hit Enter/Menu -> Program Equipment -> Hit Enter/Menu to highlight Output -> NEXT to scroll over to Equipment type field -> hit + till you display LIGHT then hit Back. Hit NEXT to highlight the MODE -> hit + till you highlight DLI then hit next.
In this second screen you will select the light sensor which you will use to control the amount of accumulated light. Ideally this would be a light sensor located near the plant level. The second entry is the accumulated light threshold which is your light target for the day.
In the third screen you will set the day start time when you light accumulator is to begin. Previously, it was reset to 0. If your threshold is not reached by the Turn On Time (shown as 3 PM in the screen), then the light will turn on and remain on until either the Light Threshold is reached or the Day End time is reached.
