I have found seeds growing in my buds, I'm at a little over 4 weeks bud, the plants are doing awesome, I'm not sure all are going to seed yet, will it spread? I'm pretty sure it came in an unfiltered fresh air intake (duh, first indoor grow). I have small plants just starting to bud will they be seed too? should I pick before seeds mature and take what I have or let them grow. This was a beautiful grow and what do I have to do to clean room for sure?
