I have had numerous greenhouses over the last 5 decades, but never one from Harbor Freight. I wanted more "substantial" ones, ones that I did not have to reinforce to have them stand up to winds. You definitely will need to go online and see how folks have reinforced their Harbor Freight greenhouses. I do have a shade-house from Harbor Freight though, 10x20', that has a shade cloth top and partial side (west) wall. If it will last at least 5 yr., I will be satisfied.
