I worked out if i only ran the lignting in your flowering room for a month it would cost me £3,144 a month. My cost per wattage (KPH) is £0.12. So your electric is quite cheap.

If i ran:
Ballast + bulb = 650w
12 x 650w = 7800w per hour
7800w x .12p = £9.36 per hour
84hpw x £9.36 = £786.24 per week
£786 x 4weeks = £3,144 a month

EDIT: sorry i got that wrong. It's £314.48 per month
12 x 650w = 7800w per hour
7.8w x .12p = £0.936 per hour
84hpw x £0.936 = £78.624 per week
£78.62 x 4weeks = £314.48

I don't know what that is in dollars but yea not too bad

I actually enjoy cleaning my table and res every week.......yes, I totally change and clean on Monday's, without fail.....3 4x4 tables and 3 40 gallon res....I clean them with H202 and RO water, and I get them sparkling in about an hour....makes me feel productive...LOL.
