Best controller for 24k watt greenhouse

[self]

Well, the title says it best. I'm running 400amps to my greenhouse and putting in 24 1000watt lights. Also heating and cooling, co2, bells and whistles. I'd like to hear from people with experience setting up commercial grows, anything over 100 amps, nothing hobby about this grow.
Thank you!

Don't use one controller, it's an expensive proposition and when it breaks, you're screwed.

Use separate lighting controllers, put each fan on its own day/night controller (so you can stagger temps and maintain negative pressure) and timers for everything else. Buy spare timers, they fail regularly.

I have a 30kw flower room, that has 6 240v relays, 3 lighting controllers, 6 fan controllers, and another 6 or 8 timers for miscellaneous things. If one timer fails, it's not a big deal. Been doing this for 15 years now. Trust me you don't want a single controller.

Use 3x8 light controllers.

Get a controller from [email protected], their controllers are very reliable, unlike powerbox and others.
