Greenhouses are absolutely awesome for year-round gardening. Being a gardener in a colder climate (my growing season is mid-May to October) this is definitely a great idea to help extend my growing season and keep the fresh veggies flowing year round. By putting this greenhouse underground, you end up saving on materials too, which makes this a cheaper, and warmer, way to grow food year round. This is one of those things I’m going to have to try as soon as I’m able to own my own land.
