There are lots of ways a business can be born from a greenhouse, whether by directly selling to other companies or stores, or by creating products that can be sold individually. This can include canned goods, artisan products, seeds, plant starters, growing kits, or entire fully grown plants, fruit, vegetables, flowers, shrubs, etc. The opportunities are truly as wide as your imagination.
Additional forms of income can also come from the greenhouse. This includes hosting classes, retreats, or group experiences so that the public can get a closer look into your greenhouse and how it functions.
