I bought the Halls Greenhouse 86. Although I've only had it erected for month it looks to be sturdy and very well designed. My only gripe would be with the instructions, some of the pictures are not clear and led to some head scratching before we finally worked out how something went together. Indeed I had to phone Greenhouse stores three time during the build to confirm how it worked - they were helpful each time. I would recommend looking on the Internet for helpful videos on how to build the green house, and encourage the company to put further videos of each stage on its website.
