It's easy to work out how much it will cost to run your equipment.

Add up the power used by each item, such as lamps and fans, in Watts.

Then, look up that number and the price you pay for a KWh of electricity on the tables below to find the weekly running cost.


1 x 600 Watt HPS
1 x 250 Watt HPS
1 x 50 Watt Fan

Total = 900 Watts

Electricity is £ 0.15 per KWh

Looking those numbers up on the tables shows that it will cost £22.68 per week if it's on for 24 hours per day, £17.01 for 18 hours per day, and £11.34 for 12 hours per day.
