how much will this cost

yo guys im looking into starting a cfl grow. im looking in getting 340 watts worth of cfls, one osicallating fan and a window fan. I pay 0.0864 kwh. I would be running 18/6 during veg (8weeks) and 12/12 flowering (8weeks). So can someone tell me how much i would be paying during veg and flowering.

56 x 0.0864 x 0.340 x (12 + 18 )

i make it about 50

50 for the enitre grow or just for a month

entire grow, you seem to have a cheap kwh
