Have to think of the progression, and the growers wants, at first all we had were regulars, then feminized seed came along, i remember people bashing them that they are inferior, and that they just grow junk, and all of them were hermies. But now look where we are, what percentage is feminized sales out there, wouldn't doubt they are in the 85+% range now of all sales. Now with autos becoming better the same thing is happening, more people are offering auto versions, but a lot are just jumping on the band wagon for increased sales producing mediocre to garbage stuff, but a few out there are actually breeding on improving auto genetics.
But yes there are regular autos out there, its just all the sales are in feminized versions as most people who grow them aren't looking for males, all they want is bud. Added bonus especially with autos is your forced to go back and buy seed every time unless you make your own, but really is that a big deal for a grower who may grow a plant or two a year, again comes down to money and sales and nothing more.
Not gonna try and convince you of anything @ray , but i will give you something to think about. Our sativa's and Indica's of today were never as potent or produced as much compared to how they did through history. The goal of them has always been to carry on their genetics, no different than how us as humans do. But for example in the wild any plant will adapt over time to gain advantages on how to carry on, some plants grow tasty fruit that the seeds of get migrated by animal sources, some plant spread roots far and wide popping up new shoots to spread as far as they can, some create seed that can float on the wind.
Cannabis if left alone over time would favor those plants that can make and reproduce the most effective, whether its the first ones to seed, the ones that grow taller than their neighbors allowing more sun and more seed to be produced, to those ones that excrete chemicals to prevent eating by animals and insects or infectious issues causing the stronger more adept ones to survive .
But here's the big one, how about plants that produce chemicals that when consumed by certain species "human" cause a wide range of pleasurable effects, which have caused humans to hunt, curate, and carry on those plants genetics because we enjoy them, and guess what over time we have cultivated and selectively picked the plants that are more beneficial to what we like, naturally that wouldn't happen, but it's the "good" genetics that are carried on by our own hand. Now who's really using whom, the plant to carry on its genetics, or us to use the plant how we see fit ?
Saying that sure adding some auto genetics to a landrace probably wouldn't help anything, but if bred over time for desirable traits who says we can't get to the same level as desirable effects, or that we aren't already getting there now.
Also the auto genetics you have to consider where it comes from, its adaptation is to carry on its genetics no different than any other plant, but for them success was to grow and finish as quick as possible cause if they didn't winter would come and kill all of those genetic lines that couldn't carry on their seed. So who's to say we aren't the ones polluting the highly tuned auto genetics that have been doing fine without us, and now were adding in stuff that slows them down, makes them less focused on seed production, produce scents and or chemicals favorable to animals, it's really on how you look at it, as there is no clear answer.
Just something to think about
