A little while ago I answered a post on what to do with unused ports. http://our.windowfarms.org/2012/01/14/can-i-use-a-petco-4-output-pump-for-a-2-column-farm/ I answered with what I did, but that got me thinking as to what should I do. Now, I would say that the correct answer is that you should cover the ports. Take a look at my video here. http://youtu.be/6KvfJyWso8E
So what does this cost me? Let’s say the pump runs at 1 watt. This is 0.001 kilowatts. The pump runs a total of 2 hours a day for me. That’s 0.002 kilowatt-hours and I pay $0.10 a kilowatt-hr. That is only $0.0002 per day or $0.073 per year. That is insignificant! I probably have wasted more power in writing this email than what it costs to run my windowfarm for the year.
So if you are very environmetally conscientious and I think most of us here are, I would say don’t worry about putting an air pump on your WF. Look else where in your life to save energy. The biggest energy consumers in my house in order are heating, hot water, clothes dryer, refrigerators, stove, computers. These are the places to make a big difference.
Buy the way, the power monitor in the video is a Watts Up Pro and I got from Fry Electronics for $120.00.
After doing the first video I decided to open it up and see how the pump works. http://youtu.be/4JqaQV48KFk
