FILL THE WATER RESERVOIR USING CITY WATER
Ensure water lines are hooked up rst (see page 6). Ensure the reservoir is free
of dirt and foreign objects before lling.
1. Remove the lower grow drawer to access the water reservoir
2. From the home screen (B), press SETUP, SET RESERVOIR (C), AUTO ON (D)
to switch to city water mode*
3. Press FILL (E) and check to make sure the water is lling into the reservoir.
The screen will display FILLING (F).
4. Once full, the cabinet’s onboard computer will maintain a constant water
level
*For manual lling, make sure to press AUTO OFF, then ll manually to the top
of the oat sensor (about 3.25” deep). Water level must be monitored and re-
plenished if it gets low.

Note: the cabinet must be plugged in or wired and plumbed by a professional technician to all applicable local and state plumbing
and electrical codes. When you power up the unit in, it will turn on and you will see the startup screen (A). The unit runs diagnos-
tics and start-up functions while this screen is visible. You do not need to do anything while the startup screen is showing. The
unit will automatically go to the HOME screen following the start up screen. To unlock the screen, press any button and a number
pad will appear. Enter “1551” then ““. Note: when the cabinet sits for long periods of time or it is turned o and then on again, it
will automatically revert to locked mode. You will have to use the unlock code any time this happens. Follow these steps to set up
your Herb cabinet for the rst time:
SET UP THE pH DOSER (pH down solution required)
Note: Auto dosing requires that the irrigation pump be primed rst.
See page 10 for instructions.
1. Remove the lower grow drawer to access the dry box (Fig. 3)
2. Place a pH dosing bottle in the dry box. Any clean bottle will do as long as
it is not taller than the dry box. Drill a hole into the cap to insert the dosing
line. If the cap is the same size as your pH down solution bottle, place the
cap from the dosing bottle onto the pH down bottle. If they are not the
same size, ll the pH dosing bottle with pH down solution. Place the bottle
into the dry box.
3. From the home screen (B), press SETUP, SET RESERVOIR (C), then
4. Press PH SENSOR (F), then
5. Set AUTO DOSE to ON (G) and then
6. Press DONE (G)
The onboard computer will check every hour and will run the dosing pump as
needed to maintain the PH level. Default PH is 5.5, but can be changed on the
SET RESERVOIR screen. Most plants need a pH level of 5 to 7.
See growing tips on page 16 regarding low pH.
Note: Calibration does not need to be done on initial set-up.
