Could my auto F2's produce non-auto plants?

[The Bedroom Gardener UK]

That's the question really - Could my auto F2's produce non-auto plants? I have two plants grown from an auto White Dwarf x Diesel Ryder which did not sex at 3 weeks.

There is a possibility of seed contamination, as in when stoned I put some seeds in the wrong bag - but I'm pretty sure I didn't.

Anyone know if this is possible?

Well, autoflowering is a recessive trait, but if you do the punnet squares, crossing two recessive traits should give you that recessive trait. So Autoflower * Photo = Photo, but Autoflower * Autoflower = Autoflower

As to if it *could* happen, I don't know. But it usually won't, to my understanding. Someone else feel free to back me up or refute me. *shrugs* It's also possible one of the autoflowers wasn't particularly stable yet?

Cheers for the reply exploring, you may be right on the stable part as the F2's had also shown a hermi trait in some of the males. I thought that an auto x auto would = auto to, but I'm only learning the ropes.

Both non-auto plants also look and smell different to each other. There's a very heavy scented one, and then a lighter scented one with shiny leaves.

A couple of pics of the shiny one.

auto x auto = auto

If both of the parents auto-flowered then the offspring will as well.

Dude, that leaf structure is bizarre...are you sure the plant isn't stressed? It'd be cool if you could run down that curly leaf trait and stabilize a plant with roundish shiny leaves like that!

Looks like it's a stoned seed bag issue then.

I'm going to take a couple of cuttings & see what happens to them no matter what. The plant could be stressed, but I'll see what becomes of her down the line.

keep them under long days till at least 5 weeks. Sometimes rarely they will autoflower at 6 weeks.

In corn there are two separate genes dealing with day neutral vs photoperiod sensitive. One has to with if it is photoperiod sensitive or not, and the other has to do with how much the plant grows before it recognizes itself as sexually mature. This gives several scenarios.

Can be day neutral and long days to maturity, day neutral with short days to maturity, photoperiod sensitive with short days to maturity, or photoperiod sensitive with long days to maturity. Ever notice how photoperiod pot plants, when grown 12/12 from the start have a set number of days before they start budding? some start at 10 days, whereas some purer hazes will grow for 2 months under 12/12 before they start making pistils.

A good idea to know if they will auto or not is if they are still putting out branches in pairs, or if they are putting out alternating branches at the top. If it is putting out alternating branches already and its not flowering, that is a good sign it isn't auto. If it is still putting out pairs of branches, then it isn't sexually mature and could be an auto plant with extended veg.

But, do you want large autos or small autos? 60-70 day autos are classified as dwarf and usually have 10-15 days of veg. They yeild 1/2 to 2 oz.

I personally think that 85 to 105 day autos with 20-40 day veg are the sweet spot. Yeilds are consistant at 1-3 oz with occasional monsters in the mix. Look at Think Different by DP.
