@Pete. Low tunnel, high tunnel, is just a matter of size, materials used and features. Same concepts and basic purpose. I just grabbed the only pic I could find that showed the cross roping. People use them on all size hoop houses, low or high. Those tie downs would probably work good for your hoops along with some paracord.
@Diana in Wisconsin - @metmom. I’m in hill country and you never know what the winds will be like here. Straight line on occasion with a lot of gusts from variable directions depending on how it funnels through the hills. We’ve had 60 mph winds but it’s been a few years. There are a couple of spots within a mile where no one should ever build. Something about the land shape pummels those spots and breaks off or uproots healthy 12+ inch trees.
Our wind RARELY comes from the East, but the two times it did since the greenhouse was built, THAT’S when the greenhouse was damaged.
It’s anchored like a BOAT - the structure isn’t going anywhere, just some of the panels popped out and one vent torn off. All was easily fixable because I found all the pieces ‘just over the hill.’ ;)
Geography can play much more of a role in local weather than people realize.
