iGrow 800 - Location Setup for Sunrise and Sunset options

The iGrow 800 has an internal astronomical clock, and the Location Setup feature allows the user to setup the latitude and longitude values and can calculate the precise sunrise and sunset times once the location of the unit is entered.

To obtain the precise Sunrise and Sunset times go to “Heavens-Above”.

Valid Location SetUp: If set to False, indicates that the latitude and longitude values are incorrect and should be ignored. If set to true indicates that the coordinates are valid/correct and can be used for sunrise and sunset time calculations.

Sunrise Sunset Times Note: When you select Sunrise or Sunset It does not mean that the Start is exactly at the sunrise time, or the End at exactly at the sunset times. You can select any time window. What it means is that the daily adjustment is per the change in the sunrise and sunset time amounts. When the days get longer, the sunrise rise time will be earlier each day and the sunset time will be later.
