OTHER FUNCTIONS IN THE MAIN RESERVOIR SCREEN
From this screen, you can automatically drain and fill your cabinet using the
DRAIN
and
FILL
buttons. In addition
to the regular DRAIN and FILL functions, there is also a
RECYCLE
function. This function can be used when all
you want to do is exchange old water for new water in the cabinet.
CAUTION:
The cabinet MUST be hooked up to city water connection AND drain for doing any of these functions. It
is equipped with a last chance option to not do an automatic drain. This is built in to make sure you are
hooked up to municipal water and drain before you perform any a drain or recycle. The screen will ask
if you are sure before beginning the draining process. A draining screen will appear for you to monitor the pro-
gress on the draining cycle.
The cabinet will automatically circulate the water in the reservoir every hour. However, the
CIRCULATE H2O
button can be used when adding nutrients. It will activate the circulation pump to stir and distribute the water in
the reservoir after adding nutrients. It will run for two minutes in the GC42 and GC12 and one minute in the
GC41 and CG11.
PROGRAMMING CYCLES
TO START A GROWING CYCLE
On the HOME screen, select a seed for the zone you have just planted (Fig. 1), and you will enter the screen with
the settings for that zone (Fig. 2).
Press the START CYCLE button and a cycle will begin. Then press the HOME button
Repeat for each zone that you have planted. Different zones can be started on different days, so not all have to
be active at the same time and you can stagger growing cycles.
The circulation pump will operate at the top of every hour to circulate the water and mix nutrients. In the GC42
and GC12, it will run for 2 minutes. In the GC41 and GC11 it will run for one minute.

WATER NOW button and start a watering cycle. Monitor the wa-
tering cycle and press the WATER NOW button again when you

cycle you want the cancel. Press START CYCLE. This will cancel
