Ask-a-Grower #159 – Cost to run a single 600watt light per month?

I was wondering since you guys are in San Diego if you knew how much it cost to run a single 600 watt hps/mh light per month.

One 600w lights is going to run you about $50 a month or more…  It is hard to tell exactly how much because of the different tiers of power sdg&e has.  You are charged x amount under baseline which allows for only so much power.  They have at least 4-5 different pricing tiers that all depend on how much total power you are using.  Another factor is the rest of the electricity you 600w would need: (ventilation fans, pumps, filters, air conditioning, etc…)
