  1. Patricia Long (verified owner)

    We installed a small thermostatically controlled heater and kept tender starts warm during late frosts. The twin-wall polycarbonate cushions heavy downpours so the noise level inside is pleasant. Solid engineering and top notch materials throughout. Very happy with this purchase. Exceeded our expectations overall.

  2. Cynthia J. (Fort Collins, CO) (verified owner)

    The gutters channel every drop of rain straight into our rain collection barrel. 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.

  3. Garrett K. (verified owner)

    Freight delivery was prompt and the aluminum extrusions were packed securely in long boxes. The clear side panels provide maximum solar gain while the opaque roof prevents leaf burn. An incredible investment for anyone who loves fresh garden vegetables and flowers. Exceeded our expectations overall.

  4. Joseph Harris (Knoxville, TN) (verified owner)

    A beautiful architectural addition to our backyard that looks like a miniature conservatory. We mounted thermometer sensors at canopy height and bench height to track temperature gradients. Five stars. Beautiful, functional greenhouse that plants absolutely love thriving in.

  5. Chris & Amanda C. (Sioux Falls, SD) (verified owner)

    The greenhouse survived an unexpected spring hail storm with zero damage to the roof panels. The diffused light reaches the lower leaves of tall plants, promoting even, bushy growth. Four stars due to peeling the protective film off all the panels, but the greenhouse is superb.

  6. Madison Flores (Fort Collins, CO) (verified owner)

    Our pepper and tomato plants started fruiting weeks earlier than in outdoor garden beds. We added foam weatherstripping around the door frame to seal out chilly late autumn drafts. An incredible investment for anyone who loves fresh garden vegetables and flowers.

  7. Jeremy Schultz (Cedar Rapids, IA) (verified owner)

    The polycarbonate sheets resist yellowing and retain their optical clarity season after season. The rain gutters have built-in hose adapters that made directing runoff to our garden beds simple. An incredible investment for anyone who loves fresh garden vegetables and flowers.

  8. Ross Hoffman (verified owner)

    We set up Riverstone MONT Greenhouse on a leveled pressure-treated base and it has transformed our gardening hobby. The roof slope sheds rain quickly so there is never standing water or dirt accumulation on top. An incredible investment for anyone who loves fresh garden vegetables and flowers.

  9. Caleb F. (verified owner)

    The humidity levels stay consistent, creating an ideal microclimate for tropical house plants. 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.
