I sent this link http://www.motherearthnews.com/do-it-yourself/build-a-cold-frame-ze0z11zkon.aspx to my dad last year, thinking he could help me build this for my garden this winter. I promised to bring materials and beer :-) in return for using his tools, space and knowledge to put this together since it’s not a project I’d ever attempted before. Imagine my surprise when he called me last night to tell me he had it almost done and ask if I wanted to pay more for plexi or less for glass.

After I recovered a bit, we started talking about the materials he purchased on my behalf and I learned that he bought pressure-treated plywood for this project thinking it was a better choice. I was concerned as I try to be organic and understood that pressure-treated wood was a no-no in the garden. My beloved father called me today to tell me that he called Mother Earth News and they told him that there should be no issues with using the cold frame in my garden.

I feel terrible about this because my dad was so nice to work on this for me but I’m concerned about any chemicals that might be introduced to my garden. I trust my fellow Folians and am wondering if anyone has some input about this.
