What is the best greenhouse for high wind areas?

If we had to narrow down to three models of greenhouse for high winds we would recommend the Riga Greenhouse (any size), the Grandio Summit, or the Grandio Elite. Any of these models have plenty of strength to withstand all but the worst storms. The main thing to prevent any issues with wind gusts or sustained high winds is to make certain you follow their respective instructions and attach them to the ground correctly. That will keep them from toppling over like a tent that hasn't been staked down. And if you know a storm is on the way be sure to close up any door or windows to keep them from rattling or swinging and causing damage. Do that and you can just about guarantee your greenhouse will make it and will last for years and years.
