If you want to go green you definitely need to make a DIY rain-collection barrel. With it you can get and store some free water to help your flowers, grass and a garden thrive. Such barrel is easy to make and won’t cost much. The idea is to place a container below a downspout and connect a hose to it. A heavy-duty industrial trash bin would be a great container to make the barrel. For instructions check out this awesome article from Workbench magazine.
