you can estimate the running cost of any setup.Running 2 - 4x4 tents with 2 SF 4000s, 4 fans, one inline fan. My power bill has gone up $100 a month in electricity charges - was hoping it wouldn't be that high, but that's what it is.
Though maybe this would help someone estimate their costs - I know I was looking for this info myself.
say my kWh cost 0.17.4p = pricePerKWh
how many hours a day do you run the device = hours
how much electricity the device uses per hour = powerUsed
how many days you be using it = days
hps 600w uses 670w, (pricePerKWh) x (powerUsed) x (hours) x (days)
.................................................0.17.4 x 0.670 x 12 x 60 = £82 per crop
add up every device fans, filter lights, etc and you have your running cost.
