P1 Photo x P1 Auto = F1 photo(recessive auto)
F1 photo x f1 photo = F2 75% photo, 25% Auto
F2 Auto x F2 Auto = F3 100% Auto
Cross the 2 F1s to go to f2. The f2 photos will be 66% recessive Auto, 33% non recessive. Two F2 photoperiods together could make some(25%) auto seeds if they're both holding the recessive auto gene. But if you manage to breed with one that's not recessive auto, you could go to f3 100% photoperiod(recessive auto), or if you cross 2 of the f2 photos not holding the recessive gene, you can go to f3 100% photoperiod non recessive. The only way to really test is to grow a bunch of beans you made and see if any auto.
That's without use of hormone manipulation.
Salut
Y en a parmis vous qui breed des autos?
A quoi je pourrai m'attendre si je croisais une auto avec une semi auto?
Ouais, c'est beau!...et flippant à la fois. Le temps passe vite, déja 10 ans!
ah bon, pourquoi moins de photopériode ? peur d'un stress ?
Thyphoon is a very old danish strain and extreme dominant sativa, early flowering and mould resistant. Ready for harvest august – september. Both yield and potency above averag, more trimming work like sensimillia but excellent hash producer.
A good Guerilla strain of unknown ancestry. The “Thy”is said to be from the place name in north-west Jutland, where a hippie colony have bred the strain for decades.
