A greenhouse can make money in a lot of ways! This includes growing and selling raw produce, as well as creating secondary, manufactured or artisan goods with what you grow. If profit is your goal, it's important to take a look at the nearby market. What's in demand near you? A farmer's market, roadside stalls, or even locally sourced restaraunts can be great places to look. Some homesteaders have found success starting a produce program with their nearby neighbors, either taking funds or trading goods in exchange for fresh, homegrown produce.
Making a profitable greenhouse will also mean minimizing your expenses to expand your bottom line. Renewable, sustainable forms of energy, and DIY projects are great ways to reduce your costs and initial investment. The structure of your greenhouse, from foundations, walls, and insides, can all be built by hand. It'll be important to waste as little as possible. This will mean capturing greywater or rainwater for irrigation, composting, and reusing old/obsolete equipment or materials.
