DIY Greenhouse on the Cheap

"Having a greenhouse can revolutionize the amount and kinds of vegetables you can grow around your home, which means a more reliable and enjoyable supply of replenishable food in the event of an emergency. These relatively simple structures allow you to extend the growing season in colder climates or even grow heat-loving plants like tomatoes in places that are otherwise too cold. A greenhouse can also serve as an incubator for plants grown from seed, which means you can purchase seeds in bulk rather than rely on having to purchase starter plants to grow your vegetables. In extreme cases, having a greenhouse in your yard can even serve as a warm retreat when there is no heat source working inside your house."
