Seeds that are grown organically for several generations tend to be better to start with for organic gardeners.
It is that selection process at work that makes organically grown seeds better for organic gardeners. They have been SELECTED for several generations to grow well without pesticides or chemical fertilizers.
Seeds that have been grown for generations under chemical conditions are not selected to withstand a few bugs, have not been selected to grow without strong fertilizers, and have not been selected as carefully in general because the organic seed label usually means the seed comes from a smaller family farm, where they know they are expected to produce higher quality seed plants using methods and materials that make the fields appealing to go into personally.
Yes, in general, ORGANIC seeds are better for gardeners who use organic methods. In fact, some of them might just do more poorly being inundated with chemicals. But not many.
It is true that the name ORGANIC has a ton of widely differing definitions. Some definitions count out some bone meals because they are heat processed. That one is too picky to me. If I put my eggshells into my woodstove they are no longer organic because I ashed them?
