    I'm so happy with this greenhouse

    I regret waiting so long to invest in a quality greenhouse. It's just so hard to know where to look and what would actually work for my climate in New Mexico. I'm so happy with this greenhouse and really grateful that Nova greenhouses took the time to answer my many many questions.

    It will stand up to all sorts of weather

    I bought this as a present for my wife and she loves it. The construction really tested my patience, but once it was all put together I can see why everyone is obsessed with this brand. I have no doubt that it will stand up to all sorts of weather.
