Winter Greenhouse Farming (video)

Rick Steffen could be thought of as a small farmer for all seasons. That’s because he grows a variety of crops, some unusual like his fruit orchards—inside a series of 55 greenhouses, some up to a half-acre in size, near Portland, Oregon. As a result, he has been able to extend the growing season, and bring earlier to the local Portland Farmers Market food (like cherries) that traditionally are still out of season here.
