First things NM has a set electricity rate, .13$ for a KWH regardless of how much electricity you use.

Ok guys tell me where I am wrong.

1.
a 1000w hps costs aprox .11$ an hour to run.
Correct or wrong?

2.
a Good grower should yield about .5grams -1gram of dried cannabis for each gram of light used?
(depending on users ability, strain, hydroponics or soil, etc.... )
