Greenhouses are here to stay, and in our urban state, it seems likely that the future will include a greater and greater percentage of production in controlled climates.  Detail oriented managers will find great success in the greenhouse.  It is definately less forgiving than the outside environment.  Our greenhouses provide us with the opportunity to produce our seedlings, provide winter shelter for livestock, increasingly we are looking to increase winter production and generally a nice place to be on a sunny December day!
