Every viable seed with the Exception of a "bad seed". Ie genetic defect... There is a lot of purpose to growing em all :). If they are all the same..

I want a lot of people to know there are a lot of "good" genetics out there, Honestly the breeders generally speaking are very passionate about cannabis. It is involved and intricate and they deserve more respect from growers. There are many fantastic breeders And a lot more "bad" growers :).
Let them get a little bit bigger then go for it and a lot of people choose the strongest looking seedling and run with that. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time"
