Im starting preperation to set up 8000-15000 watts of hps and i dont know how to get that much electricity without setting off some red flags. im thinking generator, but im not sure wether to go propane natural gas or gasoline. i also understand that some generators can be bad for ballests and lighting. And my final problem with a generator is what to do with the exaust, i cant blast hot exaust outside for obvious reasons, and i cant have it vent into the grow or my house because its toxic. Any ideas would very much appreciated, i would like to get this figured out asap!
