This greenhouse is an exceptional sturdy priceless product due to the provison of spacious roof vents, 10MM triple wall polycarbonate panels and rigid hinged wide dutch door that makes it tough to compete with versus all the other models on the market. I wish I knew about this model years ago. But like they say better late than never. This product will certainly last a lifetime and bring many happy memories for vegetable garden growers like yourself. I want to personally thank Eric Gordon and ACF Greenhouse staff for their wonderful support and hospitality in making this greenhouse a success beyond my wildest dreams. There is a Santa Claus out there folks if you truly believe in miracles. Ho! Ho! Ho! Also, have a HAPPY THANKSGIVING too and looking forward to next spring for the best growing season ever and harvest.
