I thought I would start a thread to show all the indoor growers how to calculate the amount of money their grow is costing to run. When I started growing a few years ago I did a lot of research on the cost of running my grows and have a way to calculate the cost to show you.
1. Add up the total watts that all of your equipment is rated at. Lets say for arguments sake you have a room with a 400 watt hps, a couple of fans at 40 watts, a dehumidifier at 20 watts etc. This gives you a total wattage of 460 watts in your room.
2. Now you must multiply this wattage figure by the amount of hours you are running the equipment in the room. Lets say you are in vegging stage at 18/6. Multiply 460x18 to give you the amount of kilowatt hours you are using each day.
This gives you 8280 kw/hrs.
3. Now to get the amount of units of electricity you are using simply divide 8280 by 1000 and this gives you your unit usage per day. In this case it is 8.28 units.
4. Go to your bill and get the cost per unit of electricity. For arguments sake I am going to say the cost is 15 cent per unit.
Multiply 8.28 units x .15 and this gives you a total of 1.24 euros per day. Multiply this by the days in the month and there you have the cost of you grow per month.
This has been simplified a bit because the lights may be on 18 hours but fans and other equipment may be running for longer than that but you can still use the above info to work out its cost.
Hope this helps anyone that would like to know the cost of their grow.
