This is a great product so far very pleased. I do see some of the frustrations of others with the picture assembling instructions. Took me and my eldest son about 7  hrs including time to level the ground since it was a dirt application. The deal I got through wayfair on this product was a selling point for me. I plan on having this greenhouse for many years to come. One thing to keep in mind for shelfs the outer walls are around 4 ft high this peaks to 71. My only dissapointment with this product was the shelf I bought before I got this did not fit in it. I use it for my larger plants now outside the greenhouse. I already put a light it it too recommend running wire before assembling. Going under the outer wall or out near a frame while assembling. Recommend this product my plants look great now I can be a year round gardner.
