Kind Words from happy customers

Potential customers may be interested in the following: I am retired with a very bad back and a twice broken collarbone that restricts the height I can reach with my right arm. I put the greenhouse up by myself with the help of three ladders and a bunch of bungee cords. It took six days including the time to re-do the base but a day and half of that was waiting for you to open to get information. So four and a half days for one person. We are very happy with the greenhouse.

& Benefits
