The roof vent opens with a smooth action to allow natural air circulation on warm days. The packaging included spare nuts and bolts which came in handy during the roof truss build. An incredible investment for anyone who loves fresh garden vegetables and flowers.

Our pepper and tomato plants started fruiting weeks earlier than in outdoor garden beds. The aluminum frame bolted together rigidly once all the corner brace gussets were secured. Solid engineering and top notch materials throughout. Very happy with this purchase.
Brett Cox (verified owner) –
We added automated drip irrigation lines along the staging tables for effortless plant care. The structural cross-ties provided handy mounting points for our grow lights and small circulation fans. Has completely elevated our gardening success and extended our season into the winter.

An exceptional growing shelter that has doubled our backyard garden harvest. The panels slide into continuous aluminum channels that lock them firmly against wind uplift. Has completely elevated our gardening success and extended our season into the winter.

The gutters channel every drop of rain straight into our rain collection barrel. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. Solid engineering and top notch materials throughout. Very happy with this purchase.

We hung hanging baskets of strawberries from the roof cross-members without any sagging. The headroom along the center ridge beam allows comfortable standing even for taller gardeners. Has completely elevated our gardening success and extended our season into the winter.

The twin-wall polycarbonate softens harsh sunlight while holding daytime warmth overnight. The base profile is sturdy enough to step on without bending when walking through the doorway. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.
Patricia W. (Knoxville, TN) (verified owner) –
The crystal clear side panels give a wonderful view out into the garden while working inside. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. Solid engineering and top notch materials throughout. Very happy with this purchase.
Melissa C. (Fort Collins, CO) (verified owner) –
An indispensable asset for anyone passionate about organic gardening and homesteading. The door handle latches securely in both the fully closed and partially cracked ventilation positions. Take your time leveling your foundation timbers and the frame will square up nicely.
Carol Flores (verified owner) –
The automatic vent arm we added opens by itself as the sun warms up the interior. The twin-wall polycarbonate cushions heavy downpours so the noise level inside is pleasant. Be sure to assemble on a windless day to make panel installation easy. Very solid result.
