Versatile Greenhouses

Our A-frame greenhouses serve a dual purpose. With 8mm twin-wall polycarbonate panels, they provide just the right amount of natural light, creating an ideal environment for your plants.

Built to Last & Maintenance Free

You can count on the long-lasting durability of our greenhouses. The pressure-treated structural frame ensures years of maintenance-free use. White vinyl exterior trim boards add a touch of elegance while offering extra protection.

Effective Ventilation

Proper airflow is crucial for your garden's health. Our greenhouses come with two standard roof vents on either side, allowing you to control the environment. For added convenience, consider our solar-powered fan/vent package, featuring thermostatic control for temperature regulation.

Customize Your Style

Tailor your greenhouse to your preferences. Choose paintable MiraTec composite trim for moisture, rot, and termite resistance. If you prefer an alternative to pressure-treated framing, select Douglas Fir to match your style.
