New GH

Hey go-vols,DH is building GH with PVC & treated lumber. We plan on double wall 6mil With inflated walls and was wondering how yours has held up under high winds.Ours is on turf,not cement.If anyone has any suggestions and advice,I would be thankful.Plans are for 14x38 with 5ft side walls with pitched roof.I plan on wintering all my tropicals in this and my DH swears to me it won't blow away during a storm."DH would have to blow away also as to not face me".Thanks again,you guys are a wealth of info! PS any suggestions on tie downs? he he
