Thats the fun part and the annoying part with seeds is that, theyre all technically their own plant. even seeds from tbe same exact plant will always have some sort of variation.
Even more so with autos because you cant keep parent plants around to breed back to stabilize genetics.
If you want to be able to keep a pheno or grow the strain thats advertised, youd need the exact clone or cutting to have it always be the same and the same as the plant advertised.
Getting different phenos can be fun though. i love seeing all the differenr variations but you also need to keep that in mind when using seeds.
sometimes you can even get a pheno thats so far off that it doesnt look anything like any of the other plants.
plants now a days have so many previous generations that every now and then something odd comes out.
its like that red haired child in a family with none previous. just something dormant from further
