I can only get off hour rates if I have a thermal storage unit, wich I don't. My rate is .16 something around the clock. Cheap compared to other hobbies I could have! Wood heat saves the day.
100 % now u got to buy a cmh system 630 watt de bulb will out grow your 1000 watter hps bulb
better buds and more weight easy 50% more better quality product to boot..
but will not cover as much area no false bs from me.. u have to pull in the area a bit
use to get almost a pound with hps now get 1.5 lbs after tossing out a plant or 2..
all u got to do is pull hps out put in cmh system
its a 400 cad gamble pay itself off in a yr over the hps ..
bulb is 150 need one after 5 good grows.. ovr a yr...
or dont save the power and get the cmh 1000 watt de system more better buds..
