Control Panel Basics

Select

Use the ‘Select’ button to choose the type of plants that you    

will be growing.  Each plant type has a specific light cycle that is  

pre-programmed for best growth.  The numbers below the plant 

type indicate how many hours the grow lights will be ON during a 

24-hour period.  
12-hour and 24-hour lights cycles can also be selected.   Many 

non-flowering plants grow well for the first month with 24-hour 

lights.  Some flowering plants can produce more flowers with a  

12-hour light setting. 
When starting a new seed kit, press and hold the ‘Select’ button 

for 3 seconds to reset the garden.  After 3 seconds all control panel 

lights blink on/off 3 times.  The blinking lights confirm that the 

AeroGarden has reset all relevant timers (pump, nutrient, grow 

lights). 

Reminders

Add nutrients to the water bowl when you first plant your seed kit, 

and when the ‘Add Nutrient’ light blinks (every 2 weeks).  Follow 

instructions on nutrient packaging for feeding amounts.  
The ‘Add Nutrients’ light and the ‘Add Water’ lights blink 

concurrently as a reminder to top up the water level when you add 

nutrients.  Once nutrients and water have been added, press and 

release the ‘Reset’ button to restart the nutrient timer and turn off 

the blinking lights.
‘Replace Grow Lights’ blinks after 6 months of use as 

a reminder to replace all 3 Grow Lights.  Uplug your 

garden and allow the grow lights to cool for a few minutes 

before replacing. Once replaced, press and release the ‘Reset’ 

button to restart the Grow Light timer and turn off the 

blinking light. For best results, replace grow lights every six 

months.  Replacement lights model 100340 can be ordered at 

AeroGarden.com

Grow Lights

The ‘Grow Lights’ On/Off button will temporarily turn the grow 

lights on or off. Once pressed, lights will stay on/off until the 

next time grow lights are set to go on/off.  This will not affect 

the timing of your light cycle and occasional use will not harm 

your plants.
The ‘Grow Lights’ On/Off button also allows  you to change the 

time that your Grow Lights automatically come on each day.  

To reset the time that your Grow Lights come on, follow  

 

these 2 steps:

1)  Choose the time that you want the Grow Lights to come on 

each day.   

2)  At that time, press and hold the On/Off button for 3 seconds 

then release.   

The panel lights will blink three times to confirm that the 

change to the timer was successful. The Grow Lights will now 

come ON at this time every day.  You may reset the timer as 

often as you like.

Pump

Pump settings determine how many hours the pump will run 

each day.  When your AeroGarden is plugged in the first time 

the pump will start, and the pump setting will default to the 

Germination cycle.  Your pump will continue to start at this 

same time each day, regardless of any changes made to the 

pump selection.
Germination – 1/11 hr:  On this cycle the pump runs for 1 hour 

of every 12 hours, beginning with the hour it was plugged in 

or selected.  Pump runs for 1 hour, then shuts off for 11 hours, 

and this cycle will repeat continuously throughout the 2-week 

germination cycle.  
High Growth – 24 hrs: On this cycle the pump runs 

continuously for maximum oxygenation of the nutrient 

solution.  The Pump cycle will automatically change to High 

Growth at the end of the 2-week germination period.
Interval – 5/55 (mins):  On this cycle the pump runs 5 minutes 

of every hour.  

Add Water

When the water level drops about halfway down the ‘Fill to 

Here’ indicator, the magnetic float inside the indicator will 

activate and the ‘Add Water’ light will blink.  Once water is 

added to the fill line, the blinking light will turn off.
The ‘Add Water’ light also blinks concurrently with the ‘Add 

Nutrient’ light at a 2-week interval as a reminder to top up 

water when nutrients have been added.  In this case, the light 

will shut off once the ‘Reset’ button is pressed to reset the 

nutrient timer.

A few “Bonus” tips for maximum harvests 

Planting

}

  

Many seed pods are labeled for height.  Gardens grow and  

 look their best when tall plants are placed in back, medium   

 plants on the sides, and short plants in front.  If plants are all  

 the same size, like Salad Greens, they can be planted anywhere.

}

  Do not remove Labels from seed pods.  The labels identify the 

plant type and plant height, show the germination time, and 

inhibit algae growth.

}

  Grow Domes help regulate moisture and temperature for 

optimal germination.  Leave them on until plants are nearly 

touching the domes.

}

  Large plants like tomatoes and peppers often receive fewer 

than 7 pods to compensate for the large plant size.  Place 

seed pods in each back/side opening and in the center front 

opening.  Put plant spacers in the remaining openings.

Germination

}

  Some seeds germinate in less than 24 hours.  Some take 24 days 

or more.  Most labels give an estimate of how long your seeds 

will take to germinate but many factors impact germination. 

}

  As a rule of thumb, if you are comfortable, so are your plants.  

However plants are impacted by temperature.  Cold weather 

plants like Salad Greens germinate better in cooler weather.  

Heat lovers like tomatoes and peppers will germinate faster in 

warmer temperatures (above 70 degrees F).  But don’t sweat it!  

While they may take a bit more time, your seeds will germinate.

}

  If you are growing your own seeds, plant 5-6 seeds per pod and 

check the seed packet for information regarding temperature 

and days to germination.

Pruning

}

  Lower your plants, don’t raise your lights!  You will achieve more 

compact, beautiful growth and 

bigger harvests if you prune plants 

to keep the lights closer to all 

plants.

}

  Fast growing plants (like basil) 

make gardeners want to  raise the 

lights too soon.  Resist!  Pruning 

the plant just above a new leaf 

set (Diagram A) and leaving the 

lights at the lowest position will 

ensure that slow-growing and low-

growing plants in your garden get 

all the light they need to flourish.  

}

  Not pruning is the number one 

mistake made by new AeroGardeners!  

Prune early and often and enjoy the 

small harvests! 

 

}

  Plants compete for light.  Left 

untended, more aggressive growers 

can actually block enough light to 

suppress growth of their slower 

growing neighbors, and eventually 

they can die off due to lack of light.  

Spreading leaves must be trimmed 

(Diagram B) to ensure sure that slow 

growers get enough light to thrive and produce big yields.

}

  Finally, pruning = harvesting.  Each time you prune you get to 

enjoy fresh herbs in a salad, soup, on pizza or a sandwich.  And, 

a full, bushy garden looks much better than one giant, spindly 

plant surrounded by straggly, light starved neighbors.  Pruning 

also releases a wonderful scent.  So Prune!

www.AeroGarden.com/Help.

Lights

}

  Plants love light!  Always keep your grow lights as close to your 

plants as possible.  Plants should be 1-2 inches below grow 

lights.

}

  Always check to see if you can prune plants instead of raising 

grow lights.

}

  After pruning, lower your lights back down to within 1-2 inches 

of plants if necessary.

}

  Grow Lights should be replaced every 6 months for best growth.  

Water

}

  While the AeroGarden control panel will remind you when water 

gets low, best results are achieved by topping off water regularly.

}

  Plants grown in the AeroGarden are designed to thrive with 

most municipal tap water.  Improved results can be seen with 

distilled water or reverse osmosis water, but this is not needed in 

most cases.

}

  Do not use well water, as most well water contains a high 

amount of dissolved solids that upset the balance of our 

nutrients.  This can result in plants suddenly browning, or just 

not growing well.

}

  Do not use softened water as it contains too much sodium and 

will usually harm your plants.

}

  Do not fill Bowl past fill line mark. 

Nutrients

}

  In general, your plants will need nutrients every two weeks 

when the ‘Add Nutrient’ alert activates.

}

  Always shake nutrients well 

before adding. 

}

  Follow instructions printed 

on the nutrient packaging 

for feeding amounts.  Add 

nutrients into the water bowl 

through the water fill port. 

}

  Nutrient requirements may 

change as plants grow.  See 

nutrient packaging for details.

}

  “More” isn’t better.  Resist the temptation to add “just a little 

extra.”  Too much nutrient can hurt your plants.

The included 

Trellis 

System

 will support 

your large plants, 

such as tomatoes and 

peppers, by wrapping 

around the plants as 

they grow.  
Once your plants reach 

a height where they 

would benefit from 

extra support, attach 

the 

Trellis System 

to the 

top Lamp Arm section 

as pictured. The 

Trellis

 

can be repositioned as 

plants grow.
To give plants the best 

light for growth, do not 

add 

Trellis

 until needed.

}

  For best results, try a “Rinse and Refill” once a month when 

it’s time to add nutrients.  Simply empty all water from the 

bowl, add fresh water and nutrients and reset your ‘Add 

Nutrient’ reminder.  This balances the nutrients, delivering 

an instant pick up to plants.

Harvesting

}

  Many first-time growers are hesitant to harvest.  Don’t 

be!  Most gardens will produce more, for a longer period, 

with frequent harvests.  You almost can’t begin to harvest 

(prune) early enough.

}

  AeroGardens work best with a harvesting method called 

“cut and come again.”  Simply put, you enjoy frequent small 

harvests and then watch as the plants rapidly re-grow, 

ready for harvest again and again. 

}

  Enjoy frequent, smaller harvests for the first month or two 

until plants mature and larger harvests are available.

}

  Never harvest more than 1/3 of the plant at a time.

}

 When salad greens are ready for harvest (at about 4 weeks)   

    cut the top 2 inches off the entire garden, or harvest large  

    leaves individually by cutting off at the base of the plant.

Tomatoes and Peppers

Because most people don’t have bees in their home, you 

will need to start pollinating your tomato and pepper plants 

once they begin to flower (approximately 4 – 6 weeks after 

planting). To pollinate, use one or more of the following 

methods:

}

  Place an open hand inside plant branches and gently 

move your hand back and forth to shake the plant and 

spread the pollen.

}

  Place a fan near your plants and the moving air will 

pollinate your plants.

}

   Touch the main stem of the plants with an electric 

toothbrush and allow the vibration to spread the pollen.

Cleaning and Sanitizing

After each planting, you should clean and sanitize your 

AeroGarden to reduce the risk of root pathogens that can 

destroy your crop.  Here’s how:

}

 Fill the Bowl ¾ full with water and add ¼ cup of chlorine    

  bleach.

}

  Let the water pump or aerator circulate the bleach solution 

for five minutes.

}

  Empty the bleach solution from the Bowl, rinse well, and 

then fill ¾ full of clear water (no bleach).

}

 Let the pump or aerator circulate the clear water for five    

  minutes.

}

  Empty and rinse once more to ensure that all bleach is 

rinsed from Bowl.

OR without bleach

}

  Add 5 cups of distilled white vinegar and fresh tap water to 

the Bowl and follow the instructions above.
