Hps runs about 30% efficient cmh can be as high as 40% depending on the brand/setup.so for anyone wondering why air con doesnt run as much with cmh its because the heatload is 5 to 10% less just for shits n giggles I'll add that you get more light and less heat per watt used.same reason im able to use 8kw of cob/quantum boards instead of 13kw of hps and get the same or better yields all while my ac barely runs at all now uless it goes above 65f outside.
I did save 15% by switching to geico.

This is what cmh can do for you

This is 2.5 weeks from flip. 84* canopy temp, 65% rh, 1400ppm co2, just dropped down to 1200ppm last night.

The net cant support the weight, so I would have to put stakes in. Not staking my.plants. I might kick it back up to 1400, then drop it to 1200 at week 4 or 5. This is to get a fast flip transition and bulk.

Prism ballasts
Big kahuna hoods
2x 8" 720 cfm fans (a.c. hoods)
My ac has not kicked on in almost 3 weeks! That's The only reason I run above 1000ppm co2.
I ONLY run Philips cdm elite and agro bulbs.
