This greenhouse was a perfect replacement for my previous greenhouse. the frame and roof is what really shined the most.

This is really one of the best greenhouses for professional gardeners. The insulation is terrific in this greenhouse, as the walls are more than twice as thick as in the usual kits. The wall ventilation louvers also work perfectly, so air circulation isn't among my concerns. Overall, I think this has an excellent prices, considering the offered features!

Words cannot explain how pleased I am with this product. The design, engineering and manufacturing is amazing. I have had more trouble assembling a bicycle on Christmas morning than with this greenhouse. Every piece fit exactly as it was intended. The only complaint I have is that there are literally no instructions, just drawings, so there were a couple of times that I missed a step and had to go back for a "redo", or I had to slightly "modify"a part. Things to remember... Everything MUST be level and square or it will not work. I built mine on a wooden deck, it made everything easy. As long as everything is level and square, it will be plumb and will go together easily. The little black plastic corner covers are to be installed during assembly. I missed them and had to "modify" them to make them work. A small pair of smooth faced pliers, and a rubber mallet are necessary. I lubricated the "tracks" for the window panes with WD-40 so they would slide in easier. Just a few words of instruction sure would have been helpful, now you have them. Love it !!!

Since we have plenty of space in my backyard, we decided to go for a more roomy greenhouse. This way, we'll be able to grow many flowers, herbs and vegetables, to the satisfaction of my entire family. The heaters and the misting system do a unbelievably good job in creating an environment in which our plants can grow without any problems, in all types of weather.
