With spring finally here, many people have greenery and gardening on their minds. And what better way to enjoy your favorite plants not just in the warm weather, but all year round, than by building your own greenhouse?

Having a greenhouse can help you tend to your plants while doing some good for the environment. You'll save space, have fewer operating costs and can even save energy. And with land-based sources accounting for around 80 percent of annual marine pollution, you may even want to consider composting to further your eco-friendly impact.
