Hello
@ShadyGreenThumb
I live in the zone just north of you Cheryl, and I was afraid of the cold getting under a wood floor. However I do like the idea of the rubber mats, those can be replaced if needed. You are right about the sturdy wood floor for anchoring the GH to it and the support for anything heavy. I also like the use of mylar as a heating agent. Lots to think about and why I am seeking good advise from the Forum.
Thank you Cheryl,
