You would actually like it once you figured out how to use it to your advantage.
I might, yes. Not like ours is hard. The first X kWh are 7¢/kWh, the next XX kWh it's 10¢/kWh, then 12¢ after that. The exception is summer, and after 2000kWh it goes up to 15¢/kWh.
Definitely one reason I try to use anything USB that I can, and have a kill-a-watt meter on all the garden outlets.
Aside from heaters, and there just isn't much you can do about that when you need one, I am trying to keep a 4x4 space under 600 total watts peak. Early on, it's easy to do when you can dial back the lights. Flowering, it gets tricky.
The space heaters I'm using pull 375watts, and are on temp controlled outlets. They only run during light hours, as the night time temps are about 66F which is fine. On my secondary tent, I was able to put one of the intake ducts by a register from the main house heat pump, which helps when it kicks on.
I do have backup heaters for overnight that will kick on if it gets down to 62F as a backup. They don't turn on though, so that's good.
