Choose Your Location, Fill with Water
• Your Miracle-Gro® Twelve™ Indoor Growing System
holds two gallons of water and when it’s full it can be
pretty heavy, so make sure you have it in its preferred
location before adding water to the reservoir.
Remember to keep your unit unplugged until you’ve
illed it with water and inished the setup instructions.
• When you’re ready, ill the reservoir with two gallons
of water (Look for the ill line on the inside wall.).
Return Parts to Top of Reservoir
• Place all loose components back into original places
in the reservoir with the exception of the planting site
covers [M]. Then, install the safety screws [K] at the
outside ends of the middle cover plate [G].

If you’re starting from seed or a seedling,
insert the seed starting adapter (N) to
the planting sites then place a small net
cup (Q) in the center of the adapter.
Read and follow label directions on your
Miracle-Gro Twelve Seed Starting Kit.
Take your seed starting plug and place it
in the small net cup, then add two or three
seeds to the hole in the center of the plug.
If you’re starting from a plant that’s
been grown in soil or potting mix,
insert the large net cup (O) directly
to the planting sites and place a
transplant liner [P) inside the cup.
Remove any outer cover or plastic pot
and gently place the plant (with the
soil) inside the transplant liner.

START WITH A PLANT START FROM SEED
These cups are specially designed for

Start Growing
Once you have everything set up, plug in
your system and turn it on by pushing the
switch on the bottom of the base.
Your light will come on in Grow Mode and your schedule will start immediately
(14 hours in Grow Mode and 10 hours in Off Mode). If you’d like to customize your
schedule, download our app at: miracle-gro.com/twelveapp.
10 HOURS OFF14 HOURS ON
If you’re starting with a young plant, remember to feed right away with Miracle-Gro® Twelve™
Plant Nutrition, see page 13 for how to add the nutrient to the system. If you’re starting from
seed, wait until it sprouts to feed for the irst time. Refer to the instructions on the Miracle-Gro®
Twelve™ Plant Nutrition label for additional information about how to feed.
Make sure you add water to your unit before
turning it on to prevent damage to the pump.
TIP:

12

Adding Nutrients
Plants growing in water-based systems need special nutrition that dissolves
eficiently in water and offers the right blend of essential nutrients.
Our Miracle-Gro® Twelve™ Plant Nutrition is a specially designed nutrient for
recirculating, water-based systems. With a convenient pre-dosed packet, feeding
your plants is clean and simple.
• To feed your plants, add 1 packet of
Miracle-Gro® Twelve™ Plant Nutrition directly to the
full reservoir of your Miracle-Gro® Twelve™ Indoor
Growing System.
• If you’re starting from a young plant, add nutrients at
the time of planting.
• If you’re starting from seed, once seedlings begin
to sprout and develop their irst set of leaves, it’s
time to add nutrients.
• Continue to feed your plants every four weeks
following the instructions on your Miracle-Gro®
Twelve™ Plant Nutrition label.

14
YOUR GROWING SCHEDULE
Every day your Miracle-Gro® Twelve™ Indoor Growing System will be scheduled for a
continuous 14 hours on and 10 hours off. The timer will start as soon as you turn the system
on. Use the app to customize this time to it best with your personal schedule.
NOTIFICATIONS: WHAT THE LIGHT IS TELLING YOU
Ready to Pair = Flashes twice every 3 seconds
Low Water = Flashes twice every 10 seconds
Stalled Pump = Continous lashing
Remember, do not stare directly into the light at any time.
Controlling the Grow Light
Your Miracle-Gro® Twelve™ Indoor Growing System comes with a 60W, cool-spectrum
LED grow light with three different levels of light.
TOUCH PAD
GROW
Bright light for
growing plants.
LOW
Dim light, not
for growing.
OFF
No light.
To change the mode of your light and override your
normal grow schedule, use the light touch pad on the top
of the shade to toggle through each mode. When you
override your growing schedule, a timer will start so your
schedule resumes automatically after 60 minutes.

15
Monitoring the Water Level
When you’re growing in a water-based system like the Miracle-Gro® Twelve™ Indoor
Growing System, it’s important to make sure your plants have adequate water at all
times. With a built-in water level sensor, your indoor growing system will tell you when
water needs to be added by blinking the grow light every 10 seconds.
You’ll also get a notiication from the app when you’re in range.
OVERRIDE FUNCTION
We recommend adding water as soon as your system indicates that it’s low. However,
if you choose to postpone this notiication, do not turn off your system. Instead, you can
override it for one hour at a time by pressing the light touch sensor.
To avoid damaging the pump and your plants, it is important to make
sure your system always has water in the reservoir while running.
TIP:

16
Emptying Your System
After growing and harvesting leafy greens or herbs for 8 to 10 weeks, it’s probably
time to change them out. Anytime you start new plants, we recommend draining your
reservoir and starting with fresh water and nutrients.
D
• Before you get started you’ll need a towel, a bucket
and some scissors.
• Turn off your system and remove your old plants.
• Remove the cover plates, planting frame and any
loose components from the top of your reservoir.
• Grab the tube leading to the nozzle in the center of
your device and pull up until it disconnects from the
black pump in the bottom of your reservoir.
• Take the draining tube (D) and insert the black tip
into the opening in the top of the pump, where your
nozzle used to be connected—press irmly to ensure
it is connected.
TIP:
We recommend cutting the roots to make them easier to remove.
NOZZLE

17
• Place a bucket at the end of the tube, turn your system back on and continue until
the reservoir is empty.
• When it’s inished, turn off the system, remove the draining tube, and remove
any remaining roots from the reservoir. Then, use a clean cloth to wipe down the
inside walls.
• Insert the nozzle back into the pump and add all loose components to their
designated places.
Servicing the Pump
Sometimes roots can ind their way into the pump at the bottom of the reservoir.
If your system indicates that something is wrong with the pump, empty your
reservoir and carefully clear the roots away from the pump, removing any
obstructions. If that doesn’t help, call us toll free at 1-877-309-9559 or visit
https://www.miraclegro.com/en-us/help-center.
When you’re done with your draining tube, let it air dry before you put it back in your storage bag.
TIP:
When the pump is done draining, there may still be about 1/2” of water left in the bottom of the
reservoir, but it’s okay. Leave it there and add fresh water on top of it for your next set of plants.
