wind gusts daily.....
i dont have an instrument for measuring wind gusts, but we constantly have wind around here. you are correct !!! i dont have any real wind bracing and i certainly plan on adding some this winter. when i purchased this kit, it was a bare bones kit. i have been slowly adding my personal upgrades to this house. i have rigid greenhouse panels on the south side, and rigid translucent panels on the north side. having the rigid materials on the sides, add to that all 2x6's along the base, and 2x3's to secure rigid material, believe or not this greenhouse has held up to some nasty wind. i also used my house as a windbreak and had a machine build up a wind burm for the crosswind. i definitely thought about placement when i built it.
