These were very easy to assemble. The picture shows the first greenhouse up without the cover. This part took us maybe 25 minutes to set up and then another hour for the cover, moving items in, and weighing down with cinder blocks as we did not use the rope method. Both greenhouses are up and working very well. They have been working great through our windiest season and feel extremely sturdy. We used cinderblocks all the way around vs. the ropes for extra weight. They look and feel very nice. Quiet even with the wind, and I have been using a (SAFE) small space heater as needed for myself, which really heats the whole tent a bit too quickly for just me, and we have some plants inside semi-heated aquariums! Great spaces, easy set-up, no long-term structures, and solid quality for literally any season. Thank you!!
