There's nothing like the taste of fresh, homegrown vegetables. People who live where it's warm all year long can grow fresh vegetables for most of the year. But those who live in colder climates don't have that option. When faced with shorter growing seasons, the choices are simple: either get used to doing without fresh homegrown vegetables for part of the year or grow them in a greenhouse. You may have seen big commercial greenhouses where flowers are grown. But some people make their own, smaller greenhouses for growing vegetables all year long. To make a greenhouse, you first need to build a frame. Next you have to cover it with a material that lets the light in. Glass or plastic sheeting are the most common choices. During the day, sunlight will help warm the greenhouse. If the outside temperature drops much below freezing, you'll need to supply a heating source to make sure it stays warm enough inside.
