im hooking up a generator switch (i used to be an electrician) so I get to wire the breaker to my grow room into it so if we lose power this winter ill lose a few minutes of light and nothing else, now the generator may not be able to handle the HPS, but I could easily set up some CFLs laying around to use in this scenario. If you know anything about wiring this is probably the best for the plants, but don't get yourself electrocuted again I used to be an electrician less than a year ago so I am highly confident in my abilities if your not dont try.
