Not in real life, I've seen them at growshops and in the local forums. 4x600watt used to be the safe max here to remain stealth, so the growers that do post online are usually the smaller ones who don't need it. Yet is has been mentioned 2170 times at the local grow forums according to google. That's how popular it is. They also tested several models, many growshops offer test gear to review online. I've done root riot plugs once - lucky me... I've never seen another A/C being use though, not irl, not online, not in growshops.
A common one is the 3500 serie, which is for 6x600 watt or 3x900.
The 6000 is for 10x600watt so 6x1000watt too.Probably around $4K.

Like the gavita setups, not a toy, professional horticulture equipment.
