These greenhouses grow crops specifically for commercial means, meaning that everything there will be sold for either retail or wholesale markets. Commercial greenhouses are often designed specifically to be very good at growing one or two kinds of crop, and have lots of equipment in order to make conditions perfect for those crops. Greenhouses can either sell directly to the public, or sell their crops to distributors instead.
Some commercial greenhouses sell a wide variety of options, and open their greenhouse to the public so that guests can roam and choose their plants freely. Others are more industrial, and don't allow people to enter them except for employees and managers.
