A medium greenhouse is the sweet spot for most backyard gardeners. At roughly 8x12 to 10x18 feet, it gives you room for benches, shelves, a potting area and even a chair, without taking over the whole yard.
Is a Medium Greenhouse Right for You?
- You've outgrown a small 6x8 or 8x8 and keep running out of bench space.
- You want to grow vegetables, seedlings and flowers through more of the year.
- You'd like room to walk, work and store tools inside.
Tip: Most growers wish they had bought one size bigger. If you're torn between two sizes, the larger one usually pays off.

Glass or Polycarbonate?
Glass gives crystal-clear views and a timeless look. Polycarbonate spreads light evenly, insulates better and stands up to knocks. Compare them in our glass and polycarbonate collections, or browse small and large greenhouses.
