Obviously the white, pastey looking ones are bad, but the rest should be good.
I have been growing seed from the commercial we've been getting, and I gotta tell ya, it had way too many viable seeds to be sins.
With these humble (crappy) beginnings, one would think that anything grown would be crap at best. But the final product of my last grow surpassed by far the quality of the original weed (it is actually really quite good!), and I get all females. I have started and grown over 30 of the seeds, and every one of them that reached maturity were female. Not one "hermied" either. Too many females at once to be coincidence. I am told that if a female hermies, and fertilizes itself or another female, the resulting seeds will be all (98%) female. It would appear to be true.
I believe that genetics play a significant role in the final product, but with proper care and growing, bagseed can make for some pretty killer weed!!!
