With how common LEDs are nowadays it'd probably be hard to spot a difference between a small grow operation and a 14-hour-a-day streamer. A consistent 1200+ watt jump at around the same time, day in and day out in both scenarios
Yep, or all us self-hosters. I have a 200 watt machine that comes on at specified times to run Backups.
Then there's solar and batteries. Grow operations could setup a battery farm that charges slowly from the grid so it never shows a spike, and run everything off the batteries.
2 computers, one with a capture card, a digital audio converter, lighting, etc etc. Main rig might be pulling 600ish watts but there's probably 500 watts of miscellaneous other stuff
