  • For a more permanent foundation, the concrete slab poured to the frost line is the way to go.
  • If you choose this type though make sure to add texture to it to keep it from being slippery when wet.
  • The concrete block or wall is another great way of setting the foundation for a greenhouse.
  • Examine your choices and decide which foundation is for you.

  • Some use PVC tubing or pipe, others like aluminum or painted aluminum.
  • Many gardeners buy their framing materials and do not build their own, because most people do not own pipe bending tools and experience needed to complete the task.
  • The frame is one of the critical parts of the process, it determines the strength the structure will have.
  • This is up to you and the shape of the structure you are planning, which we will discuss later in more depth and detail.

  • Tempered glass is much stronger if you are going to have glass panes on your greenhouse.
  • If you are only building a temporary greenhouse though you can even use plastic sheeting to cover your structure.

  • With the other foundations use a combination of landscape fabric along with gravel under your planting benches.
  • Use either bricks or treated lumber for a walkway through the greenhouse.
  • Many people simply put their greenhouse in their backyard with wood, concrete, brick, or even tile.
  • Keep in mind greenhouse maintenance and upkeep while purchasing the surface floors.
