F1 has always been vigerous growing photo for me. Faster veg faster bloom.
Crossing photo with auto = photo?

Hey bro
yes you are right and like kaos said the flowering time of the f1 will be faster then the photo parent, i got the same resault with my project.

I think that quite possibly not all "autos" so neatly follow such Mendelian recessive gene expectations. In some instances, it may be more than just a simple recessive gene trait and there's other things in play including envoromental conditions which can also influence gene expression.

Summarizing the Role of Dominance and Recessivity
Mendel's early work with pea plants provided the foundational knowledge for genetics, but Mendel's simple example of two alleles, one dominant and one recessive, for a given gene is a rarity. In fact, dominance and recessiveness are not actually allelic properties. Rather, they are effects that can only be measured in relation to the effects of other alleles at the same locus. Furthermore, dominance may change according to the level of organization of the phenotype. Variations of dominance highlight the complexity of understanding genetic influences on phenotypes.

I'm no expert here, which is why I included the links above. However, I can offer some anecdotal evidence from my own, very admittedly minor experience a few years ago
Some full auto seeds were gifted to me in a sealed breeders pack .... I believe they were called betty boo by joint dr. Upon growing the pack outdoors, all were full autos and showed sex by week 3. I selected the best male for pollen collection and culled the other males. The biggest, healthiest and most promising looking/smelling females were then pollinated thereby producing much seed. I'm hesitant to call these "f1" as I have no idea if the original seeds were backcrossed or not. I believe this seed "type" or "strain" was never offered for sale but a very short and limited time...... possibly due to the "breeder" noticing the same type of experiences I eventually did??
Some of these newly produced seeds (f1?) were grown indoors ... and again every one was reliably a full auto. Upon disposing of this material via vaporization and combustion, a few seeds were discovered although no herm or errant pollen source was noticed. (This isn't that unusual as I often run much longer than the norm with many plants sometimes throwing a bananna or male flower very late in flower.)
Eight seeds were eventually collected and these were germinated outdoors. These seeds were highly suspected of being S1 and therefore all females. Out of those eight plants all were eventually confirmed females, but only two of the eight were full autos! The other six plants were indeed full photos and did not show sex till late summer ...many months after being germinated!
The original auto plants (and their first generation I produced) all were very typical small autoflower types with most finishing out well under 20 inches or so in height. They were also fairly similar in smell, appearances, tastes and affects.
The few plants grown from the small group of eight S1 seeds were allot more variable. The two that were full autos fairly closely resembled their parents and were as expected. The other six started out similar ..... yet during early flower stretched enormously then started exhibiting wildly differing characteristics both smell and appearance wise. Although grown under the same conditions, soil and treatment, one of them even turned completely purple and eventually almost black or eggplant in color (due to the seasonal drops in nightime temps) from top to bottom. All of these six plants finished in late october with most being well over 4 foot in height and could of been much bigger if the conditions allowed me to let them go without allot of restraints and tying down to prevent unwanted attention.
I would certainly love to hear anyones ideas as to why this happened or to confirm my own suspicions that the environmental aspects (and possibly even some genetic "bottlenecking") were the reason for the revert to full phototype expressions. This experience has certainly had me scratching my head wondering for a few years now. It would be great to finally get to the bottom of what likely happened.
I did use some of the first pollen I colleted to selectively seed that last run by crossing them back to their "grandparent", but lost intrest and moved on to other projects. Perhaps this coming spring I'll germ some and see what they do for nothing other than I'm quite curious again after having typed this and reminding myself

Absolute right i have some Chemmy Lemmys(dnas Lemon Walker Photoperiod x Mephistos Chemdogging) F1 going atm. Day 20 12/12 and already sprinling Resin like mad. Last Photo x Auto Cross was finished in 7 weeks whilst the normal Photo i used as Mum was a 9 weeker(reserva privada Kandy Kush)
