Hydro

Does anyone know approx. how much their hydro jumped up when going to 3 250W Metal Halides? How about 3 400W Metal Halides?

I believe it was under $20/mo. I recall that the difference betwee n250w and 400w was very little, due to the amperage draw from the ballasts.

a simple rough calc is 3 x 250 W = 0.75 KW x 10 hr/d = 7.5 KWh.

Look at your power bill and you should see the overall cost per KWh.
