Along with MinniBratt's, LabRat's, and everyone else's suggestions...
I saw mention of using CFLs for vegging.
I didn't see (or must have missed it) anyone suggest that you immediately unscrew EVERY light (that isn't used for MJ growing) in your residence that isn't a CFL or LED, throw them away, and get CFL or LED replacements.
As a matter of fact, immediately is too late - do it yesterday.
As mentioned, trade off those 1kW lights for 600s. They are more efficient so you can net the same amount of lumens (using more fixtures) while using less electricity. And as they're more efficient, they produce less heat. So, less a/c usage.
And that's another thing... I like it in the mid 60s, but if I had power bills like that I'd learn to deal with temperatures that had me sweating while sitting naked and not moving. You need to keep your GR cool - for the rest of the residence (and the people in it), use fans (ceiling fans are great) instead.
And... If it is AT ALL possible,
remove the heat from the GR instead of cooling it; IOW, try to vent that hot air outside. One of the reasons that air-cooled fixtures are great is that you can pull the heat from them out of your GR without picking up the smell of the GR in the process. It's a lot easier to put it outside if it just smells like air lol. Your plants won't care if it's ten degrees cooler because you've put a glass lens on the light, ran the ducting so that you're drawing air over them that came from somewhere else, and then sending that heated air somewhere else - or whether you're pushing the combined heat/smell into another part of your residence and then trying to single-handedly finance those new upgrades down at the power station by running your a/c nonstop.
But that second way seems like trying to bake bread in your oven while leaving the oven door open and then sticking an a/c unit in the window to cool off the kitchen. Me, I keep the oven door shut and turn the vent on so (most of) the heat that is coming off of the oven goes right outside.
BTW, thanks for the chuckle! (All I had running was...)
Worse comes to worse, rent the apartment beside yours, cut a couple of small holes in the wall between them, and run outlets from the second apartment into the first one. It'll cost you, but running lights like that you are probably still making some serious bones. Or just go rent a four- or five-bedroom house.
i told them that i got my wife a tanning bed
That was also worth a minor chuckle: I bet after the girl got off the phone with you she found herself wondering just how many hours every day your wife spent in that tanning bed lol.
