The assembly diagrams presented some ambiguity, but our main concern was the need for extra internal height. To address this, we opted for a raised foundation during mounting. Generally satisfied with the outcome, although there's a need for further adjustment to achieve a better fit between the door and the window.

Excellance

While I have received my greenhouse the weather has not yet been good enough to assemble. The customer service with both seller and shipping was excellent. Thank you

Sigma greenhouse

Mary was super helpful a pleasure to talk to and was always there. The Sigma Greenhouse on the other hand is very cheaply made. I hope it stay standing. Trying to figure out how to add more bracing.

Hi Traci:

Thank you for taking time to review our products, your option will be sent to the manufactures for improvement. The Sigma greenhouse is durable like sungrow model with round design and cost friendly, and we believe it will meet your gardening need.

Wonderful greenhouse

We are not construction folks so we hired a construction person to assist the three of us in the assembly. Even with his help we found the directions pretty confusing sometimes. It took us 4 days to get the 20’ version set up, and we have still not installed the roof vents. Even though it was more challenging that we expected it to be from the reviews we are still in love with the greenhouse. It is very sturdy (has already weathered 30 mph winds with no problems) and very attractive.
