Customer Feedback

"Why did we buy the Cultivator Premier? Because of the reputation of National Greenhouse Co.® A greenhouse is not something you shop for every day. We trusted National Greenhouse Co.®when we read how long you had been in business and were not disappointed. Reading that what I bought would be ‘direct from the manufacturer' made me feel comfortable. The greenhouse arrived on time, and the instruction manual was easy to follow. My husband and I put it up over a weekend. We even had time to sit on the porch and enjoy the look of the finished product. It is just what I wanted."

"I ordered the Cultivator Premier greenhouse from you on the Internet...I'm completely overwhelmed with pride with the outcome of the finished greenhouse. It is VERY HIGH QUALITY and certainly worth the money I spent."

"We decided to grow our own herbs and vegetables to be healthier. Everything I read said the best place for growing your own vegetables was in a greenhouse. After lots of research we chose the Cultivator Premier and it was a good choice. We have lots of room for our growing benches, and there is still plenty of working space for me. We are learning more every month about our new hobby and feeling healthier as we do."

"I put my Cultivator Premier at the back of my yard next to my English cutting garden. It makes a beautiful picture when I look out my kitchen window. I couldn't believe that I could get a green painted frame at no additional charge. My Cultivator Premier allows me to start my seeds early in the spring so I can get a jump start on the annuals for my garden."
