You'll get a photo period or an auto. You'd have to grow out several F2 plants to see if you could find most of th traits you want. Then you need to feminize it. However, its not as simple as just genetics. Genes can have multiple expressions that will be brought forth depending on environmental parameters. The OG Kush you buy from, say, Sensi, may not grow the same for me as it does for you. This is expressed in pheno types. With an F2, you may not even get the pheno type you think you picked!


what about incesting the F2 cases in hope for a F3?

Can you quote that post? I missed where I stated it like that.
Guys, I can't keep up! Hahaha!

I took this part as an implicit statement that you think the best yield is when you run them 24/0:

"I have a tent full of photoperiod plants on 24/0 lighting, they are a little older than a month and many have sexed already. Why wouldn't I just grow that on 12/12 if that was my plight?Same veg as what is being suggested for a semi-auto, same light cycle for flowering. Only difference is that the claim is a semi-auto can still flower on other schedules, just not to it's potential max."

Maybe I was wrong.

Listen, I'm high af. I know I can sound like a pain in the ass when writing stuff down, but it's all friendly, right? I'm just always looking for knowledge and like to be thorough.
 
If all that mattered was yield, we'd all grow photo periods because, even with the currently available good yielding autos, photo periods are still superior in that department. And F1 cross is a collection of all the available genetics of the 2 plants, and all dominant genes prevail. You can't select for the traits you actually desire till later generations.
A super auto / semi auto will never be a stable strain because once you go to F2, the genetics begin to shake out into photos and autos again, thats how you find the autos in an auto/phot cross. The you take those that auto and the earliest males and make F3 auto seeds. These will be a larger percentage of auto flowering plants F5 is considered the beginning point of stabilization.

Creating an F1 strain is not work, it is only step one in a long process.
That's all fine then. So, you say: the breeder should go on breeding to get a stable autoflowering plant. This still doesn't prove that all seeds marketed as semi-autoflowering are not stable. Let alone that these are all F1. How can we know that it is all F1? You can't tell by looking at a seed, I imagine?
 
So here's a theoretical discussion topic for the eclipse party for all you green thumb gurus. :greenthumb:

Are multitudes of outdoor growers across the US running into the risk of the solar eclipse turning off or turning down the sun enough and/or long enough to possibly stress out plants to the point of possibly getting a whole big crop of hermi's this year? Kind of like turning off your lights in a photoperiod grow room for five minutes in the middle of the day randomly one day (power outage, maybe?). :baked:
