it took 5 people a 3 hours 4 days to assemble this 4ft x 6tf poly %26 metal slat green house! all adults with skill levels. the picture with qrs codes ate worthless. .usic to loud to hear instructions. instructions leave much to be desired. i secured it to a wood base for stability. you can NOT caulk plastic windows as you go ad you have to keep loosening screws to install panes. i sealed areas after putting it together. the slide open window is difficultvto install and is crocked and has a big gap. i was very frustrated %26 almost se t it back 3 times! its finally together, sealed mostly. ill be surprised if it lasts 1 summer. i do not recommend.
