Anchor it to the ground or a foundation; un-anchored, the first real storm wrecks it.
A roof vent is not optional; on a sunny day a closed greenhouse cooks the plants inside.
Clear heavy snow off the roof, or the panels and frame can buckle.
Assemble it on a still day with two people; the light panels catch the wind like sails.
