While legal marijuana is earning some respect after decades of prosecution, it is also changing the way the plant is grown and harvested. Small producers are being squeezed out and large ones are consolidating the market. There is a wide variety of products offered for sale, more than a small farm can create. It wasn’t supposed to be this way. Pot growing was the ultimate small business. One could with a few plants and grow lights make a living. That is no longer true and small producers are being forced to specialize to survive. While legal weed is gaining a positive reputation, fewer producers are successful. It is the iron law of economics.
