The Cost of Electricity for your Grow Room

With the cost of electricity constantly rising we need to be concerned with grow room lighting.

Different lights require different amounts of electricity, so how do we determine beforehand what operating expenses will cost?

You can calculate cost of electricity fairly easily. First find out what you are being charged per kilowatt. This should be on your electric bill.

Let's say you pay $.08 per kilowatt per hour, your lighting system is 300 watts and you run your lights for 16 hours per day:

300 watts is .33 of a kilowatt so .08 x .33 = $.03 per hour x 16 hours = $.48 for 16 hours. .48 x 30 days = $14.40 per month to run the lights.

As you can see the calculation will give you a rough idea as to how much you will pay for lighting.
