You can get $5000 or a lot more for a single bottle (~1 plant) of wine, too. But if you're growing acres of either crop you aren't making those numbers reliably.
Is your bottle of wine ready for market in 6 months or less from when you plant your vineyard? Probably not though. The speed at which you can get these yields is another huge advantage for these crops. Some commercial growers are having new plants grow up to harvest continuously, with separate rooms for vegetative growing, flowering, and even maintaining a genetic library of clones fit for expanding and out planting in your greenhouse. You can also grow this crop anywhere in the world, unlike grapevine.
You have to have 3 rooms, otherwise you're buying clones, which is stupid expensive, when you can just take cuttings and make your own super easy. The two precursor rooms don't require nearly as much space or power though.
