Explain a few things for me, please.

In here I read certain words that I don't fully understand:

1. What is a "pheno" I know it's short for phenotype, but what is a phenotype?

2. What does F1, F2, F3 (Is there an F3?) mean?

I'm sure there are others, I just can't think of them right now.

Phenotype - generally the characteristics the plant shows, mostly sativa or mostly indica traits, although theres quite alot more that i cant think of off the top of my head (stuff like tall/short, wide/skinny leaves, high/low THC content percentage (or something like that))

F1 is the first generation of offspring

im pretty sure F1, F2 and F3 Refers to the seed generation.... btw also i forget where but there is a RIU terms dictionary with a shitload of terms with good definitions... search it up

Somebody crosses a male and a female to produce a new strain of seed. That seed would be F1. They then grow that F1 seed to produce more seed and that seed would be F2. etc, etc.

Is that right?

Phenotype = characteristics of plant. Got it.

airwave with the crossbreeding info is correct. genetically enhanced plants.....thats where its going and let it keep growin

Here is the answer to all your questions https://www.rollitup.org/newbie-central/3423-vocabulary-growing-terms-slang.html

Some cool info, but kinda technical.
F1s are the first generation hybrids, a cross of two plants with unique characteristics. Like a short, sweet indica x tall, skunky sativa resulting in a F1 cross that is short and skunky. ( just for example, could be the other way too )
some useful quotes from wikipedia :
"Once the characteristics of the cross are known, repeating this cross will yield exactly the same result."
"Both inbreeding and crossing the lines [typically by hand] requires a lot of work, which translates into a much higher seed cost"
"The main advantage of F1 hybrids in agriculture is also their drawback. When F1 cultivars are used for the breeding of a new generation, their offspring (F2 generation) will vary greatly from one another.."

What I get from your post:
F1 seeds will have the same phenotype (characteristics) as the plant that those seeds came from. But F2 seeds could have a different phenotype. This means that phenotype degenerates through the generations. This would also explain why F1 seeds seem to be more expensive.

Agree or disagree?

Agree. It's that the pheno is less predictable.
Lets say you get some regular F1 seeds from a good breeder. Generally the plants will be consistent, but not totally. ( they aren't clones ) If you cross a male and a female that you grow from those seeds, you will have an F2 generation where the individual seed's characteristics will vary considerably.

Thanks to all that responded.
