Mebby this will help.. or confuse
Im not a genetic breeding wizzard..
S1, (selfed) or Regular seeds should have a specific purpose.
Cannabis can be manipulated to influence traits for example:
-Female to male ratio of seeds can be increased with specific environmental conditions, more blues, high nitrogen, cool temps.
-A female regular or feminized can be intentionally stressed or accidentally stressed to show hermaphrodite traits. A plant could have monocoecious traits.. in a "regular" pack. There is a genetic test for this.
-We can manipulate hormones to force traits either way via supression of ethelyene with collodial silver to force male herm traits for selfing in a female.
-We can also use ethyelene to stop herm traits by treating it with products like Dutch Master Reverse or Optic Foliar Switch.
S1 (selfed) are not perfect either.
-Selfed seeds DO show some phenotype varation, it is limited, however the generation of S1 seeds should not show a significant population of hermies, but repeated selfing would increase the frequency of herms.
Soo... It depends on your goal. S1 Seed Criteria:
-Need the most females possible for production or limited grow area, S1's seem to work, I've used them before without any need for sprays to supress nanners. Any herms that show should be culled.
-I have some "elite" cuts.. I'm selfing them for phenotype preservation and eventual outcrossing.
-You dont give a fuck about breeding, you just want fems for flowers.. S1's will work for you.
Regular Seed Criteria: F1,F2.
-You're looking for a stud or phenotype variety to breed with.
-You dont want herm traits on a line you know to have problems.
-You dont like the cost of femmed lines.
-You dont mind pheno fishing,
Its how I see things. I might be wrong...
