Hey mate.
You know that using Colloidal Silver (T.M in your case) can cause a high variability in the possibility of genetic mutated offspring with undesirable characteristics. Need to do research on your strain prior to producing seeds and check with the breeder if its suitable for creating a S1. Some breeders like to create S1's/S2's & S3's (selfed offspring) which is what you're basically doing in order to get the most desirable characteristics and to keep potential (undesirable) phenotypes out of the genepool. If (in the event) that your strain has already been selfed a few times in its genetics that would make it unsuitable for breeding.
Goodluck with your project and sending some karma your way!! Always great to see people producing their own seeds
