This past weekend I got a chance to put my wife's new greenhouse up. I really liked it after I got it up, but here are the problems I had with the installation. The instructions are not very easy to understand for someone, if they are not mechanically inclined. Also most of the tubing for the frame was bent on the end wear the pieces connect do to poor headlining when packing, some of them were not flared properly. I have my Owen  flaring tool so it was an easy fix for me but would not be for someone with out the tools. I am sure this would be a easy fix if these issues were addressed and make your product and other products you are advertising more appealing to your customers.
