Meh, most of the weed I buy has like hundreds of seeds in an ounce. I hate seeds, I hate schwag(for the most part), and I hate being broke and in school. But it is true that weed with seeds is "less potent" than non seeded weed if you are talking about simply thc/weight=potency simply because the seeds take up space inside the calyx that would have been filled with more thc instead of a seed. But the seeds don't affect the potency of non-pollinated calyxs so seeds don't necessarily make the non-seed part less potent, they just make you get less smokable material.
