Interesting, I will do some research on this. So is it safe to say the short one is the indica showing more and the tall ones are sativa traits?
Will they produce the same buds smoke wise, or with they actually be different?
Indica and Sativa are misnomers as they don't actually indicate anything at this point aside from possibly the overall length of time it takes to harvest. Even that is subjective.
In the industry, they are looking to move past those names(cultivars) and strain(chemovars) names in general because it is the terpene and cannabinoid profiles that give an inclination to how the end product may affect the user.
Because of phenotypical differences among cultivars, the morphology(growth structures) from seed to seed will vary along with
Time to harvest
Aroma/taste(terpenes)
Color
Root growth
Pest/Pathogen/Disease resistance
Tolerance to Environment
This isn't an exhaustive list by no means but like a mother and father producing children, genetic variation will happen as each seed possesses the genetic blueprint of both cultivars.
Overall, I'd make no assumptions because ILGM sources their seeds from white label breeders - only they know who bred them or if they even have the qualifications which could lead to wild genetic variation, in the case of autos they may not auto.
This is different than Mephisto or Rocbud or Jean O or Mandalorian Genetics whom all breed their own genetics. Think Seedsman, so with that said you're guess is as good as mine but what you can do them is give them all an equally consistent, clean, controlled environment.
Breeder times are variable just like the bud that will be produced from phenotype to phenotype. Beyond that, I'm no breeder but those with good skills can have fairly homogenized results. I know my favorite breeders produces F1 seeds that are 70-80% similar is most ways from pheno to pheno compared to what I've gotten from Seedsman or other breeders.
