What size greenhouse do I need for a home garden?

Choose greenhouse size based on your growing goals:

• 4' x 4' (Backyard Raised Bed): Perfect for seedling starting, herbs, and a few tomato plants. Fits on a deck or small patio.
• 6' x 8': Small hobby greenhouse — room for 2-3 raised beds or several pots. Good for herbs, greens, and starter plants.
• 10' x 20': Serious home garden — walking space, multiple raised beds, hanging baskets. Enough for a family's vegetable production.
• 12' x 20' to 12' x 24': Market garden scale — commercial-grade growing space for market sales or large families.

Allow 30% of floor space for walkways and work area.
