This can be a five star for you, but a few things to note
The instructions are scant. I started to build section by section, so front panel, side panels, floor and back panel and roof. Very Important: The polls must be fully inserted into the joints or the canopy won't fit. I put together the front panel, and hammered in those that were stubborn. For the remaining joints, I used vaseline for every single joint where poles would go. Every one. I assembled the first part in the kitchen but it got big fast, so I put everything on the back deck where the greenhouse would reside until summer. I also used an interlocking gym flooring for extra insulation during the Northeastern winter. After I assembled the roof, I placed the canopy on the roof section. I then added the sides, back, bottom and front. After the first rain, a saw a couple of small puddles on the gym flooring. So I added poles under the flooring and on top of the deck, along the perimeter of the greenhouse so that the water could not flow inside. It worked. I LOVE this greenhouse. Note also that there are 50-65 mph winds here so I not only tied the greenhouse to deck rails, but weighted down the inside floor poles with cinder blocks and ran secondary ties to concrete weights, and more concrete weights to the lip around the bottom of the greenhouse. The plants are loving it. If the shelves keep popping off, you can zip tie them to the poles. Canopy fits well, opens up well, fantastic. Also, I put bricks on my woodstove and add them to the greenhouse during very cold weather
