F2 Strains
Since you crossed a male and a female from Skunk #1 which is an F1 hybrid, you created an F2 generation. When you grow these seeds out you notice the plants look drastically different from one another. Some are way taller, some more short and stocky. They smell different from one another too. Some have that skunky funk aroma and some are more sweet and fruity. So what’s going on here? Why are all these F2 generation, f1 weed strain plants so drastically different?
In the F2 generation, a genetic process called “recombination” takes effect which remixes, in a sense, all the traits present that were passed on from the P1 generation. Where you had plants in the F1 generation that were relatively similar looking, the F2s are all over the place. Some are tall, lanky and take longer to ripen, a distinct trait from their sativa heritage. Others are short and stocky, and their flowers finish fast, a trait inherited from their indica lineage f1 weed strain.
F3 and Beyond
Back to our tropical ganja paradise scenario, let’s say you make F3 seeds by selecting the most THC potent male and female. In the F3 generation you see more uniformity in the traits between plants, with a handful of exceptions. If you took the highest THC plants from the F3 generation, and bred them together to make an F4 generation, you’d notice almost all of the plants were very potent. You have essentially created seed that bred true for high potency.
