Aerogarden Light and Pump settings

February 21st, 2008

I just set up my new AeroGarden, and the lights (or Pump) won’t stay on

The AeroGarden is programmed to have its Grow Bulbs and Pump on for only a certain number of hours per day, which varies depending upon which seed kit you are growing. The Grow Bulbs and Pump do not necessarily run at the same time.Depending on the setting, the AeroGarden Pump and lights will run as follows:

AeroGarden Classic

Plant Type

Lights On

Pump On


16 hours

20 hours

Salad Greens

16.5 hours

24 hours


17 hours

17 hours


15.5 hours

20 hours


16 hours

16 hours

Unless your garden is set to Salad Greens where the Pump is programmed to run continuously, your AeroGarden may be at a point in its cycle where the Pump and Grow Bulbs are programmed to be off. Every AeroGarden is tested at the factory before it is packed. During this testing the garden’s initial cycle may be interrupted, so that the next time it is plugged in, the AeroGarden will finish out that initial cycle before resuming its regular, full-timed cycle. If it happens to have been interrupted at the point in the cycle where the Pump and Grow Bulbs are supposed to be off, it will appear to be malfunctioning when it is merely between cycles. With the AeroGarden Classic, set it on Salad Greens and the Pump should run continuously, and the Grow Bulbs should run 16 out of 24 hours. If setting the garden to Salad Greens shows that the base is good but the cycle is off where you’d like it to be, you can set the AeroGarden to come on (OR go off, but not both) its 24-hour cycle when you want, by following one of the procedures below:For setting the time your AeroGarden comes on:

  1. Decide what time you want your AeroGarden to come on.
  2. At that time of day, press the “Lights” button and hold it down until the green light next to the plant selection flashes, then continue holding it until the LED light blinks faster – about 12 seconds. Release the button.
  3. Your lights will now come on at this time each day.

For setting the time your AeroGarden goes off:

  1. Decide what time of the day you want the lights to go off. At that time check that the lights are on. If they are off, quickly press and release the “Lights” button.
  2. Press and hold the “Lights” button for about 5 seconds, until the green light next to the plant setting starts blinking. Release the button when the flashing begins.
  3. When the blinking stops, the lights will go off. Your lights are now set to go off at this time every day.

    What’s the power consumption of the aerogarden when the pump and lights are on? I’m a bit concerned running one for 24×7 but fresh salad does appeal a lot.

    I find the concept intregeing ,but would like to know a lot more with regards to eg. NPK ,colour spectrum and availability of spares etc. Another question- how much control can the user have to adjust photoperiod and such ?Cheers Jon.

    We are told by the American manufacturer that an Aerogarden has a power consumption of 0.8 kilowatt hour per day total consumption.
