  1. Paul & Megan G. (Peoria, IL) (verified owner) –

    No glass to break if an errant pebble flies from the lawn mower, making it very safe for pets. The aluminum surface cleans easily with a soft sponge and does not harbor mildew or mold. An incredible investment for anyone who loves fresh garden vegetables and flowers.

  2. Lance K. (verified owner) –

    The anchoring base frame bolted securely into our perimeter timber foundation with heavy screws. The aluminum frame bolted together rigidly once all the corner brace gussets were secured. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.

  3. Timothy Y. (verified owner) –

    The sliding door glides on smooth overhead bearings and latches closed securely. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.

  4. Paul & Megan M. (Greenville, SC) (verified owner) –

    The greenhouse holds solar heat remarkably well, staying ten degrees warmer than the outside air at dusk. The twin-wall polycarbonate cushions heavy downpours so the noise level inside is pleasant. Has completely elevated our gardening success and extended our season into the winter.

  5. Mitchell B. (Chattanooga, TN) (verified owner) –

    The automatic vent arm we added opens by itself as the sun warms up the interior. The foundation clips gripped the bottom rail securely and screwed into our 4×4 base timbers. An incredible investment for anyone who loves fresh garden vegetables and flowers.

  6. Roger Cooper (verified owner) –

    The polycarbonate panels survived golf-ball-sized hail without cracking or denting. The roof vent hinge operates smoothly and allows excess humidity to escape on sunny mornings. Solid engineering and top notch materials throughout. Very happy with this purchase.

  7. Jeff & Amy Cook (verified owner) –

    The crystal clear side walls give us full visibility into our plants from the kitchen window. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.

  8. Jacob Gomez (verified owner) –

    Survived a windy spring storm with 40 mph gusts without any panel rattle or frame deflection. The roof vent hinge operates smoothly and allows excess humidity to escape on sunny mornings. Has completely elevated our gardening success and extended our season into the winter.

  9. Bobby O. (Bozeman, MT) (verified owner) –

    The humidity levels stay consistent, creating an ideal microclimate for tropical house plants. The door handle latches securely in both the fully closed and partially cracked ventilation positions. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in. Glad we chose this model over the alternatives.

  10. Edward S. (Boise, ID) (verified owner) –

    Freight delivery was prompt and the aluminum extrusions were packed securely in long boxes. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. Be sure to assemble on a windless day to make panel installation easy. Very solid result.
