buying seeds.

[Robert C. Wood]

I am seeing a lot of show and documentaries on the ill effects of gmo seeds. I would like to know how do you tell which seed producers are non gmo, other than the ones that state organically produced? 

[Scott Roberts]

You, as a consumer, are not going to be purchasing any GMO seed. GMO seed does not come in a packet. Purchasing GMO seed generally requires a signed agreement with the seed company.

Long story short: Don't worry about it.

If you plant heirlooms, you can save seeds, in most cases.  Some are more difficult than others.
