This grow room electricity calculator will help you understand the cost of electricity while growing cannabis.
Electricity consumption is an important consideration when budgeting for your grow.
Most growers have no idea how to budget for their electricity because calculating it is confusing.
That’s why I decided to create this simple calculator, that allows you to see how much you are likely to spend on your electricity over the course of your grow.
The inspiration for this calculator came from this awesome article from our friends over at GrowWeedEasy
How Does The Calculator Work?
The grow room electricity calculator uses the following equation to calculate the cost of electricity during your grow:
Let’s take a look at each part of the equation:
Cost of Electricity
This is the cost of electricity that you pay and you can usually find it on your bill.
It’s measured in kWh.
However, if you can’t find this, you can use the national average to get a rough idea, which is $0.12 in the USA and $0.10 in Canada.
Number of Hours ( for vegetative and flowering )
This is the number of hours that you will be running your electrical appliance every day.
During the Vegetative stage, most growers opt to keep their grow lights on for 18 hours and then switch them off for 12 to give the plants a rest.
However, some growers like to leave their lights on for 24 hours every day as it speeds up the vegetative growth – just be mindful that this light-dark cycle will increase your electricity bill.
This is the number of watts that your electrical appliance draws from the wall.
This could be your grow light, a rotating desk fan, or exhaust that’s sucking the air out of your grow tent.
This value is then divided by 1000 to convert the number of watts used to KiloWatts (kW)
So there we have it, a simple way to estimate the cost of electricity during your grow.
