Forty-eight square feet doesn't sound like much until you're standing inside with herbs on one bench, seedlings on another, and room to pot up your tomato starts on the third. This 6X8 Single Slope is the smallest greenhouse in our lineup, and for a lot of growers, it's all they need.

Dark gray bottom siding with white trim and translucent panels above — the darker base absorbs warmth on cool mornings while the angled roof catches sunlight at a low angle. Sliding windows and an exhaust fan keep things from getting too humid. The single slope design also drains rain and snow without pooling.

This one's sold, but we build them to order. Same construction, your color picks. If you're tight on space but serious about extending your season, this is the greenhouse to start with.
