I just got one of these. The supplier sent me a different (older?) video of a much more stable looking greenhouse with feet on every frame and extra cross supports. I'm a bit dismayed by how wobbly this looks. And neither video showed whether you need concrete in the holes afterwards or if it will hold in packed earth. Also, the ends of the plastic panels in the ground should be sealed somehow against algae. I will build it anyway, but I'm much less confident it will survive the wind. 😢
