so if you got your seeds from some bud you where smoking and grew a plant that ending up being a female from thatbag seed
how much more potent would a sensimilla bud be then the oringianl seed laden bud??
Good question.
Unfortunately, its impossible to answer it, because potency can vary a great deal based on how a strain is grown and when its harvested.
So the answer is going to depend on how well the seeded bud in questoin was grown compared to its potential, and then how much of that same potential you get growing it yourself.
If the seeded stuff was harvested early, and cured poorly, you may see major (ie like night and day) improvements in both potency and taste compared to the same stuff grown properly, without seeds, harvested at its peak, then cured properly. If you're specifically asking about the case of outdoor grown seeded Mexican commercial "schwagg" bricked bud, if you were to actually grow some yourself and do it right, you may be surprised at just how good the end product is compared to the brown crumbly stuff you started with!
On the other hand, if you were to take a good outdoor landrace sativa strain, grow it outdoors *with seeds* up in the mountains, again harvest at its peak and cure it right, you're probably not going to see ANY improvement growing it indoors under artificial lights, and in fact, what you end up with probably won't be as good, even though it lacks seeds!
Speaking in general, the most important difference in terms of seeded vs non-seeded isn't absolute potency, its YIELD.
If you grow seeded plants, the yield of smokeable stuff goes way down because the plant spends so much of its energy making seeds, and the final mass of the bud is mostly the weight of the actual seeds. So on a per gram basis, most of its weight is going to be seeds, and the potency will be lower. If you pick out the seeds, though, the stuff that remains can still be pretty potent.
As food for thought, famous breeder DJ Short (creator of the original "Blueberry" strain) has opined that seeded cannabis may contain different cannabinoid ratios than unseeded, and though it may not be as potent on a per-gram basis, it may actually offer a better *quality* of high.
Lastly, a few seeds in the final product may decrease bag appeal a little bit for "pot snobs" but they really don't mean ANYTHING in terms of quality or potency. In fact the most potent stuff I've ever tried in my life (Williams Wonder from the early 1990s) had a few seeds in it, and if I could ever find another bag of it, I wouldn't trade it for any non-seeded stuff!
