Quictent greenhouses are great ! I own a retail nursery and needed more space to grow plants but commercial metal pole greenhouses can cost $2000 for a basic 20'x10' structure. Quictent greenhouses provide a sturdy structure at a price point of $250 for that same size. The steel is not as strong as a commercial greenhouse, but for that price I didn't expect it to be. This is a GREAT solution for me, a good price and it is sturdy and stays up. We anchored the base poles with large U clips from a hardware store and put up a rope over the top in 2 places, also anchored. We have high winds in our area and snow. I had some issues with snow and Quictent cusotmer support was amazing. Super fast response and so helpful to get us replacement parts. Khloee helped us out on the latest snow problem and was great to work with. I have 2 Quictent 20'x10' heavy duty greenhouses. Under a 12" snow load, one greenhouse stood up and the other collapsed inward. They got us repacement parts at a reduced price, super fast. And now we have put up a wood support inside under the center bar, so we won't have any issues with snow in the future. GREAT customer service and a great price for the quality.
