Concerning the electricity consumption I should have mentioned there are plenty of times (first two and last two weeks of the grow, and when I go out of town so I don't have to water as much) that I'm only running half the diodes on my lights. I only run the veg set the first two flower only the last two weeks and like now when I'm about to go camping for two days I will leave just the flower on. So basically on the early 2011 model 180s I'm only running 65w of total power, on the PG 250 which as a lot more flowering diodes 100w of power, on the new model 180 about 77w total so that helps keep the bills down too.
