3. Vertical Hydroponic Gardening
Growing your own food is by far the most effective way to become self-sufficient. It’s healthier, you know what’s in it and you can have a steady, constant supply. The benefit of vertical gardening is that it can be done even in tight spaces, urban areas and is highly efficient. Ready-made kits are available to purchase or with a little research, you could build your own.
While you won’t generate any power by composting, it’s a great activity for conserving energy and resources by using waste to cultivate new growth in your garden. The ultimate in self-sufficiency is to be able to feed yourself with things you grow and composting is both easy and cheap and provides the perfect natural fertilizer without any harmful chemicals.
