Welcome Popey,
That's a good question. The sativa genetics will obviously be mixed/diluted with the autoflowering strain used in the first outcross, but with proper selections in the F2 and F3 generations (and further) towards the sativa expressions and traits you want to breed for then you can end up with a 100% autoflowering strain with plenty of sativa traits, like it's the case of our Auto Malawi x NL, the newer F4 generation has even higher frequency of sativa phenos and traits, so at the end it's just a matter of selecting towards your goals, in thihttps://www.icmag.com/ic/newreply.php?do=newreply&p=8449122s case to produce a 100 % autoflowering strain with the stronger sativa influence as possible.
Hope it helps with your doubts. Btw, we are starting to test the new Auto Zamaldelica indoors and results seem to be promising so far in early flowering, lots of vigor during growth and strong sativa traits .... must wait a bit more to know how much desirable Zamaldelica's influence the Auto Zamaldelica F3 carries.
It's great that there is being attention turned to the need for autoflowering Sativas.I'll be watching for those Auto Zamaldelica trials to be posted up for all of us to drool over.
Ok.When will you start the Autoflowering Congo Dubi?
