Oppolite Oppolite 120"X60"X80" Mylar Hydroponic

Bought a 10' x 5' x 80", arrived a day early. Frame goes up quick, once you figure out the instructions are in the bag with the nylon straps-- and you convert inches to CM in order to figure out which diagram to follow. So my 120" x 60" x 80" used the instructions for a 300cm x 150 cm x 200 cm. Then it was easy to follow the small diagram and assemble. I did have to use some straps to hold down the Parts 5 and 6 that clip over the top for bracing, as they kept coming loose. May not be an issue now the cover is on. Definitely a 2 person job to figure out how the cover goes on. I second the other reviewer that wished he had put the floor down first, I would have found that helpful too. But once we manhandled it around the frame it started to make sense, and we put the top on first then the sides. Quality seems excellent, heavy material, heavy zippers. Did realize we needed to unzip one door as we assembled so we could see inside as we got more cover on. Inside measure is 78 inches tall in the corners, mght be a bit lower where the braces go across. Overall size is slightly less than the 120" x 60" advertised. The cm measure is probably the accurate sizing.
