    Mixed feelings

    So, after many online searches I decided to purchase this green house. The overall quality is slightly better than the average. The instructions are ok at best they tried to do as little written instructions as possible, but the drawings can be confusing. The instructions tell you to read them first and I highly advise you do so as mine was missing several pieces. So, I had to wait and extra week to start on the assembly. The customer service from the manufacture was very good no argument on the missing parts they sent everything I needed right away. Some of the assembly was questionable (like how to fasten the auto vent feature). I guess we will see how it holds up. Would I buy again? only time will tell

    Love this greenhouse

    Absolutely love my little greenhouse (and so do my plants). It took my husband about a weekend to put together and then another few days to add the additional items like the sprinklers and sink. He said it would have been faster if he had another set of hands, but totally doable. Well constructed and quality items as well.

    I absolutely love that the vent auto opens. We installed a fan that auto turns on at a set temp as well as heat lamps that come on automatically. It seriously makes growing seedlings and plants in the cooler months so easy!

    Greenhouse

    Love the greenhouse, only gave 4 stars since we had difficulties with the directions for setup. They was a change in parts that was not reflected in the documentation and also were missing parts. The greenhouse currently resides within a heated metal shed. We have installed lighting and a misting system for humidity all regulated by timers. Currently growing Asian cucumbers, radishes, banana and bell peppers, sugarcane peas and tomatoes.

    Once put together the greenhouse

    Once put together the greenhouse is attractive and very well constructed. But it was much more difficult to assemble than advertised. Took 2 men 2 full days. And they both are adept at construction.
