you wont get any autos in the first generation..your going to have to grow and cross some F1's. then grow out the F2's (2nd generation) you should find about 25% autos in
the F2's. then cross two autos for 100% auto trait. your still going to have to inbreed if you want a fully stable strain..the only prob is you going to want to grow out LOTS
of the F2s so you can find good auto pheno's... as for faster flowering,im sure you'll find a pheno in the first generation of a auto/reg cross that will flower faster then others.
but theres no other way to find them other then to grow out LOTS of the F1's so you can find that faster flowering pheno/trait...and when i say "LOTS" i mean 100's or 1000s
if you got the room.. cause if you only grow out a few your not going to see all the differnt pheno/traits..
