measuring yield: hygrohybrid vs industrial grow-op

Thread starter #1
Hi,
I've been watching hygrohybrid videos about growing hydroponic cannabis. They are really good. He says that he targets 1 gram per watt and usually reaches that number. Usually he has 4k watt setup in a room. How does hygro's relative yield compare to an industrial grow-op? Do those industrial grow-op benefit from an economy of scale? And do they measure their yield by the kilowatt hour?

Thanks,
Chris
