If you've ever lost seedlings to a late frost or watched tomatoes struggle because you started them too late — this greenhouse fixes that. Eighty square feet of protected growing space in an 8X10 footprint that fits most backyards without a permit headache.

The iron ore LP SmartSide siding with matching trim gives it a darker look that actually helps absorb heat on cool spring mornings. The translucent polycarbonate roof lets light through without turning the inside into an oven. Four sliding windows and a 16-inch exhaust fan keep airflow steady when things warm up.

Potting benches on three sides give you room to work, and the 2x4 pressure-treated frame means it handles snow loads and wind just fine. This one's sold, but we can build the same thing in your choice of colors.
