Greenhouses can be heated in order to grow out-of-season vegetables year-round, and can be built at any scale in order to feed even the largest family. The excellent variety of crops that can grow in a greenhouse make it an even better option for feeding a family year round in times of need. The size of the family will determine the size of the greenhouse that would have to be built, but that can be easily figured out through research.
One of the most remarkable pluses about greenhouses is that they are incredibly adaptable to climate. They can be insulated to withstand the winters as well as fortified with sturdier rods in case of heavy winds and rain. The summer months are the easiest to maintain, but they can also be harsh due to the heavy rains that ensue. A cheap way to make sure your greenhouse makes it through the summer storms would be using PVC piping, a relatively cheap option.
