A greenhouse provide an especially ideal place for plants to grow, safe from the environment and less than ideal conditions. You can grow specific crops that are suited to your family's taste, and you'll know exactly what is going in to their production. Food that ripens on the vine, and is picked and immediately eaten is more flavorful and maintains far more nutrients than when it's picked still green and shipped around the country or the world. Anyone who has tried fresh tomatoes off the vine can vouch for this.
Subsistence agriculture is usually the core goal of homesteading. This means growing food solely for feeding yourself and your family. A greenhouse creates ideal conditions for produce, growing them larger, happier, and healthier. Greenhouses are incredibly easy to DIY, and can be built in pretty much any and every budget.
