please critique my greenhouse foundation

16 years ago

Hello All:

I would like to run my greenhouse foundation plans by the users of this forum.

I purchased a SunGlow 8 X 15 greenhouse. I am planning on using two layers of 4X4 for the base. I will lay 6 mil poly to serve as a vapor barrier and poke some holes for drainage. I will then add 2 inch foam boards for ground insulation, followed by pressure treated plywood or some form of decking material (to protect the foam boards from being crushed by the gravel and to add another layer of insluation). I will then add pea gravel on top of this.

Any problems with this plan?

Comments and suggestions will be much appreciated.
