Greenhouses make money through individual business or brand ventures at grocery stores, farmers markets, restaraunts, etc. or by agreeing to sell their crops to a middle-man distribution company. Greenhouses can also offer classes, growing kits, seedlings or plant starters, travel retreats, group experiences, etc.
Some greenhouses are open to the public, and allow individuals to roam the aisles and pick out their own products to be bought on-site. Othertimes, products are transported to stores, stalls, or markets to be sold there.
