I have always loved a greenhouse. I love the way the soil smells clean and earthy, the humidity steams my skin and hair, the plants may be blooming and fragrant. I've been known to visit a greenhouse just for a mental health break.
As my interest in urban farming has grown, I've become aware that a greenhouse is more than just a luxury location for potted flowers. A greenhouse is an urban farming tool that can significantly expand the seasons in spring and fall.
Last summer we purchased a greenhouse kit on sale for $350 at our local home supply store. It was a humble kit for a 6x8 foot greenhouse with aluminum frame and 6mm polycarbonate twin walls. There is a sliding door in one end and a small roof vent in the top to allow for air exchange.
We decided to build a raised bed along one of the 8 foot wall lengths. The other half of the greenhouse is open floor, which allows flexibility in terms of container plants, shelves for seed starting, or general winter storage.
