Losing a generation?

So if I grow some Sour Diesel plants and find a few seeds and use them for my next grow will I lose a generation or potency from using the seeds from the first grow?

Ummm, No. Essentially the seeds you find will contain the same genetics as the original plant(s). As long as the seed was given time to develop fully, then youll have no problems growing on those seeds.

sounds like your plants hermied., you could get fem plants or more hermies. If you use those seeds you are more likely to get seeds in your next crop.
