    Greenhouse

    Love so far, my husband put it together pretty easily, especially with the YouTube videos, quality is great, sturdy, price appropriate. Good experience with the company also so far. However be aware this kit is not for an inexperienced person to build, you need tools and a clue or it might not go so well. But that is not a company issue! We are happy.

    Sigma Urban Kit Greenhouse

    Overall I have been very happy with this greenhouse. It has not yet been through an Alaskan winter, so I'll reserve complete judgement on its for now. From the sturdiness of it I expect it will do just fine this winter.

    But for two minor issues I would have rated this kit 5-star. Delivery of the kit was very timely. Putting it together went relatively smoothly. Only two points in the assembly caused minor inconvenience or confusion:

    (1) During the installation of the covering panels, the shortness of the screws (#53) made sliding the side panels into the brackets impossible. I had to buy screws locally that were a 1/2 inch longer and then the installation went quickly.

    (2) The kit included door and window linings (Y1-Y12) which are not referenced anywhere in the instructions, nor do they fit any of the doors or windows -- hinge cutouts are the wrong size and in the wrong locations. Very confusing, but have no apparent affect on the greenhouse function.

    Thanks for a great product.
