        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.

        I Finally received the greenhouse today. It seems so far all packages are in good shape. I am going through the hardware and seeing if all is there. So far so good. I have not got to the panels at this time. Thank you Mary for your help it was encouraging to see the company has you to help with this. You were very helpful and I will tell anyone looking for a greenhouse to use your company.
        Thank you again.

        Sigma 20

        I love the greenhouse just wish the nuts and bolts were a little bigger. Kind of hard to hold them when putting together , also the latches in the doors don't work when you add the metal frame over the poly. They need to be offset . I had to bend them so they would work.
