Hello. I bought this tent for my greenhouse. I have a large greenhouse made out of recycled bus shelters and I had the roof built by a greenhouse builder. This is the 4th year I've had this tent in there. It is opened every morning with the roof pushed back and closed every night with the roof pulled closed and zipped up. The tent is in great shape for so much opening and closing, but it has had some small repairs too. You guys might consider to build a greenhouse special where it easier to fully open and close or a tennis court special tent for the rich people who don't use their tennis court anymore and want to use it for growing. They both need to be easy to open and close every day and be sort of UV protected and I guess the tennis court one would have to be weather proof too. Oh well just an idea. Chuck. Oh yes, please see my diaries too just to see the tent. Chuck.
