Direct from the Manufacturer
The Cultivator Premier and Cultivator Elite greenhouses are shipped directly from the National Greenhouse Co. manufacturing facility to you.

Made in the USA
All of our greenhouses and the structure materials are American made, and we’re proud of it! Many greenhouse kits are manufactured overseas. Not the Cultivator Premier or Cultivator Elite! They are designed and manufactured here in the U.S. with your growing and climate conditions in mind. When you buy the Cultivator Premier or Cultivator Elite Greehouse, you are buying the best in a manufactured and designed greenhouse kit at a very competitive price.
