Sorting plants by photoperiod

I tried to search for this but was unable to find specific information. This idea came to me reading different breeders stories of how they sorted out landrace plants by photoperiod.

If you sprout a number of seeds, any that flower under 18+ hours of light are autos, 14.5 hours or less more indica, and 12 hours or less to trigger sativas. Breeders would also veg at 13 hours to produce more sativa expressions, and sort out any plants that flowered under that photoperiod.

So what I’m interested in is that I have some F1’s of sativa/indica hybrids and I want to sort out the later flowering phenotypes so that outdoor plants at 42 latitude finish up nice and ripe. They are beanhoarder Meo Thai/Malawi(Malawi pheno) x PCK seeds and flowering is centred at 10.5 weeks. I can do 10.5 weeks no problem, I just want the plants that start to flower a little earlier as opposed to a little later. There may be long flowering phenotypes which when sorted could go to a buddies greenhouse.

My plan is to check some cuttings at 14 hours of photoperiod and see which show sex. On an average year we can leave plants well into November, I just like to get things done a little earlier with the extra heat. Does this make sense? Any comments, thoughts or advice is appreciated.

Another question; I have read that the farms in California are using clones to grow those fields of monster sized ball shaped trees. If overall size/yield is the criteria then which is better from clones or from seed? Does it affect finishing time at all? This is yard not guerrilla.

I can give you a kinda answer. Clones are better if you a market grower because of consistency...all the same. It can be tested in large batches keeping your testing cost lower. From seed they all ripen differently. It is a nightmare. I have seen it done. For a yard growing seeds is alot more interesting, it is like watching sisters grow up. They're the same, but they're not.
