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.
