Prefabricated Greenhouses
Interesting article on greenhouses, partially in reference to prefabricated greenhouses:
A greenhouse is something that might really enhance your enjoyment of gardening, but who wants to spend the money to build a standard (non-prefab) structure? Especially now when everyone is trying to save money. Anyway, who knows, if you do it cheaply enough and grow the right vegetables, you might make your money back on the construction costs.
