hi guys its my first time growing i am currently running a 400watt hps im pretty usless with maths and would some one be able to help me figure out the running costs ive looked at tha how to calculate but its all gobbledegoop to me. heres some figures 6.750 pence per kilowatt hour not sure what else i need to be doing numbers and me dont mix lol thanks in advance
The Cost to Run a Lighting System To get the operating cost per hour for a light, take the lights combined wattage, and divide it by 1000 to get the kilowatts used. Then multiply that number by the amount your electric company charges per kilowatt hour. HID lights will use the number of watts it emits per hour, ie; 600w system will use 600 watts per hour (regardless of spectrum). so if im running a 400watt @ 6.750 per khour it will be 4.05045 is that per hour or for the total i have no idea what a kilowatt hour is is it just a hour or more?its all gobbledgoop lol
