OPERATING INSTRUCTIONS
TIMER OPERATION
The timer will turn the light system on and off based
on the chosen settings, creating a regular light and
dark cycle for plants just as they would experience
when growing outdoors.
Different plants will grow best under different light
cycle conditions; some need more light and some
need less. Check the back of the seed packet for
information on the best light cycle to set for the
plants being grown.
To program the timer:
1. Press and hold the set button for 5 seconds until
“TS” appears on the display.
2. Press the up and down arrows to set the current
time to the nearest hour. The default time is
12:00 am, indicated by a ‘0’.
3. Once the current time is set, there are two preset
operating modes to choose from.
• Press the up arrow to choose preset P1.
• P1:
12 hour light cycle, meaning the lights
will be on for 12 hours and off for 12 hours.
• Press the down arrow to choose preset P2.
• P2:
18 hour light cycle, meaning the lights
will be on for 18 hours and off for 6 hours.
Note:
The timer is a 24 hour clock and can only be
set to the closest hour.
For example, if the current time is 3:45 pm, set
the clock to 16 indicating 4:00 pm. Always set the
current time to the nearest hour.
The timer will not display the current time. It uses the
set time as a guideline for the day and night cycle
and to count the hours before turning the light on or
off.
