im not talking about growing two different types of plants.

i want to know if i took a package of durban poison seeds (or any kind of strain( and grew both a male and female of that particular strain so that i could acquire more seeds in order to poractice without going into the poorhouse whether or not the second batch of seeds produced from the originals would be any weaker than the originals.


so basically what im looking at is,........


1> spend 100 bucks on a given seed strain, for conversation sake, durban poison.

2> grow the pack of 10 seeds, allow a male and female from this package of durban poison seeds to pollenate and grow seeds of their own.

3> now from this pollenation i have a bunch of durban poison seeds to grow more durban poison plants later and can spend money on a different strain right?

OR are these new seeds not as good for some reason as their originals?

if they are weaker, why?

essentially im trying to ask if the strain will lose its potency or characteristics through simple breeding of two of the same strain type.
