HomeGro RDWC User Guide
small side is 1 teaspoon. Recommended dosing
is 1 teaspoon per gallon of water. It’s good to
know that 1 big scoop (Tbsp) is equal to 3 small
scoops (tsp).
First Nutrient Addition:
MaxiGro: Add 4 large level scoops (2 Tbsp)
After planting your system, you will be growing
in the Vegetative cycle and using MaxiGro
nutrients only. Your weekly dose will be 4 large
level scoops of MaxiGro until you switch to the
Bloom stage. After switching the timers for
Bloom, you will start using the MaxiBloom
nutrients in the same dose (4 large level scoops
every 7 days). A standard bloom stage lasts
about 8 weeks. Be sure to record when you
switch your lights over to the bloom cycle so
you can plan your nutrient flush prior to
harvest.
The nutrient flush is simply removing all
nutrient water from the reservoir 1 week prior
to harvest. Refill the reservoir with clean pure
water. Drain and refill again 3 days prior to
harvest to ensure a thorough flush prior.
Using Third Party Nutrients –
While the HomeGro provides all the nutrients
required for three full grow cycles, you are free
to use other nutrient lines. Be careful to select
nutrients that clearly state approved for use in
“recirculating hydroponic systems”. Many
nutrient lines are designed for soil or a drain to
waste hydroponic system. Choosing the wrong
nutrient line can clog the system and result in a
broken pump.
Setting Timer
The HomeGro RDWC comes with one pre-
programmed timer set to Pacific Standard Time.
This timer is used to automate the lighting to
align with the needs of the plants. The light
timer comes pre-programmed to turn on at
6am and off at 12am. This provides plants with
18 hours of light daily, which is perfect for a
vegetative growth stage. Plug the timer in to
the power strip and plug the light in to the
timer. Check the timer display for the current
mode. The timers require that users set them
to Auto On or Auto Off depending on the time
period they are plugged in. If plugged in during
the on period of the timer, select Auto On, if
during the off period, select Auto Off.
Example: if turning system on at 7PM, the light
timer must be set to Auto On mode because the
light should be on at that time.
To change the mode, simply press the manual
button on the timer until the desired Auto
setting is shown.
Switching from Veg to Bloom Light Cycle
To switch the plants from Vegetative to Bloom
growth cycle, the Light Timer will need to be
switched to be on for only 12 hours per day.
The timer comes pre-programmed for the
Vegetative cycle of the plant (6am-12am PST).
Our recommended Bloom cycle is from 6am-
6pm.
To adjust the timer for Bloom, simply press the
“+”button twice, until the LCD screen flashes
1off. Press the “set” button twice, then using
the “+”button change the time to 6pm. Once
set, press the “time” button to return to the
main screen.
