I am too cheap to spring for a plug in watt meter, and my power bills have been high lately. This prompted me to figure out some things about power. I decided to share them with everyone. If your power meter does not have a spinning disc this article is not for you.
First, Turn your grow on with everything that would normally be on during the time your grow would be on. Like your computer, television, etc...
Next thing to do would be to look at your power meter (the box on the side of your house). Pick a point on the spinning disc dealy and count how long it takes to get to that same spot. For mine it was 13 seconds. You also want to look for a number that has a small Kh annotated next to it on the meter itself. Mine is 7.2 as is alot of them.
Next you use this formula watts are measured in per hour, this tripped me up while figuring all of this out.
Watts=3600*the Kh number/the number of seconds it took per revolution
so mine was 3600*7.2/13= 1993 Watts
Take this number and move the decimal to the left 3 times (mine was 1.993 or 2). This will give you kilowatt hours. multiply by 24 and you have how many kilowatt hours you are using per day(mine was 4
Last thing that you can now do is look at you power bill and average how many kilowatt hours you used last month or recent months into per day format. Then compare it. If it is drastically more than normal with your grow on you may want to consider shutting off an appliance or two to conserve electricity. I turned my hot tub off, now only using it when i decide to warm it up.
I hope this helps someone else because it was really important as my parents pay my power bill and got pissed about this lol.
