There is nothing in the world like a bowl of freshly-picked lettuce. The fresh delicate flavors don't compare to the store-bought lettuce that sits on the shelf all week (and growing your own saves tons of money, too). You don't need a farm or even a backyard; a good-sized container with drainage holes will do the trick and provide you with enough lettuce for you and a friend. A wooden planter box will also work if you're short on space. Just don't try to grow lettuce on a windowsill; the temperature swings are too great.
