My experience with recent (last ten years) bagseeds is that you'll get some pretty weak plants initially that exhibit reduced vigor, and are very difficult to grow to any satisfying size or yield. However, if you employ bagseed from mutliple sources and permit them to pollinate one another, the seeds you get from that will exhibit good vigor and will grow well.
Prior to that, back in the 70's, everyone where I lived (Pacific Northwest) smoked fully-seeded products from Mexico ...sativas...and so the seeds were all original landrace strains from wherever...Oaxaca, Columbia, etc. It was different then, the seeds grew true and everything you grew was better than the bag you took it out of by a pretty fair margin.
These days, everyone uses "Dutch" hybrids which won't grow right because if you got a seed it was from a hermie or something, plus it's hybridized in the first instance, so the outcome is unpredictable.
I have found that the product from modern bagseed will be much prettier and tastier than the original schwag.....due to all that loving you baked into it....but the potency doesn't change much.
So in my several experiments with bagseed, I ended up with product that had superb visual appeal, smelled great, burned good and was very enjoyable after a few weeks cure, but wasn't any better than what I got the seeds out of. And I had to run two cycles....the first with some pretty sad and sickly seed-mommas....to get anything.
I'd recommend getting some good genetics. I would have been better off to purchase/bargain/trade for a good quality genetic stock.
Which, ultimateley, is exactly what I did. I don't care for Indica, the high isn't what I want, the potency isn't what I want, and you can't get a true landrace (native, natural strain that God created so it's heavenly to grow) so I spent time accumulating native sativa landraces.
Since I prefer my youthful experience, I don't sell, I grow only for personal use, I let every crop seed out. I use seeds, I let them pollinate, I make more seeds, it always grows true, it kicks yer head into gear....just like when I was a kid
A big, fully-seeded sativa bud may not have the quantity you might otherwise achieve, but I've found no diminishment in potency actually, and it has a different character that's difficult to describe. AND, you got more free high-quality uber seeds than you can imagine, at zero cost....
in good soil outdoor in a good hiding spot with good sunlight and you made sure to 1. use your own soil 2. use correct nutrients 3. have a spot with lots of sunlight 4. let it mature all the way not even a day early picking 5. cured it as best as i know how (about 65-75%of the way dry with de-humidifier in closet then chop it all off, leaving big stems on, and putting it in a brown paper bag in a nice enviroment for as long as it takes to be perfectly crisp)
