Indoor gardening - without the mess of using dirt!  You can DO this using dirt but why would you?I've been doing this for many years but to some people it's a new idea.  This is a good way to offset rising grocery prices, especially produce prices.  It's easy, fun, fast and relatively cheap to do (compared to store prices it's really cheap).
