  # How much energy does the AeroGarden use?

Let's get real - these days, it's important to have an understanding of how much energy you use.  It's the responsible thing to do! We take pride in the low amounts of energy that AeroGardens use.  Read on, we did the math for you!

To calculate how much energy an AeroGarden uses, we use the following formula:

-- The number of hours each day that your AeroGarden is on (based on type of garden planted and AeroGarden type itself), multiplied by

-- The wattage figure given above for your model AeroGarden (divided by 1000 to convert it to kilowatts, as used by the electric company), multiplied by

-- 31 days a  month, multiplied by

-- The cost per kilowatt hour charged by your utility (in this case \$.11 kw/hour)

For example, in a cubicle in one of our office at AeroGrow we are growing Gourmet Herbs (on 17 hours a day) in an AeroGarden Bounty (which uses 48 watts, or 0.048 kilowatts, of power).  This AeroGarden is on for 31 days a month, at an average utility rate of approximately \$0.11 per kilowatt hour of electricity.

 AeroGarden Model Wattage Used (Average) Cost to Run Per Month at 11¢ Per kw/hour AeroGarden Farm 126 watts \$7.30 per month AeroGarden Bounty 48 watts \$2.78 per month AeroGarden Harvest 23 watts \$1.33 per month AeroGarden Sprout 13 watts \$0.75 per month
