Hey gang,
I failed science in high school, so my punnet square is all buggered. If I take pollen from an auto and pollinate one of my purple diesels, is the likelihood of getting an autoflower fem seed 1:4 (25%)???
Pollen is from a femmed auto that I stressed until it grew some balls.
Purple diesel x think different = think purple?..think diesel?..different diesel?..different purple?
Also…if I bred a femmed auto this way, how can I stabilize that femmed auto trait? Breed it with itself or use the femmed pollen?
Yep, or better in my limited experience.

From what I’ve been told the first generation will be 100% photoperiod as it is a dominant trait. If you make f2s roughly 25% should be autos.
I made some seeds like this when my Mr sparkle autos were inadvertently pollinated by a male I had hanging out in my sunroom, I’m really curious what will come out of them. I’ve started 4 as testers and 2 seem to be mutant freaks, I’m not sure if that’s due to the autoXphoto crossing or what
To stabilize it I would first lock onto the auto trait by crossing 2 auto f2s which I believe should give all auto kids , then you can feminize them however you like.
This should help answer your question
Lol…punnet square and everything. Thanks mang!!
Quick question for you…in your tagged post, you talk about breeding photo and auto and the odds of getting another auto…however, if I crossed an auto and a photo, took 20 of those seeds and 2 were female auto, could I colloidal silver those to stabilize the auto trait?..or would the photo still be dominant and express itself in those seeds?
Almost… if you crosses an auto and a photo, all 20 of those seeds would be a photo. You would have to cross those seeds (F2) before the auto trait appeared. An auto crossed with an auto will always be an auto, regardless of if you feminized them or not.
What general traits do autos impart to f1s with regs? Shorter height or flowering times?
IME they will cut down on flowering times. This is often called a “Fast Version” by many seedbanks. My Juanita la Lagrimosa x Lowryder2 cross went from 11 weeks to 8.

Close, but no cigar.
Auto x Photos = Fast Photos that’ll start flowering earlier than normal outdoors, but won’t auto. If you Ix em then Fast Photo x Fast Photo will give you 25% autoflowers, 75% photoperiods in the F2 generation.
So it would take two more generations to be full autos?
Right. In order to produce a batch of autos, both parents have to be fully autoflowering.
Do you think this is what the xl autos are ?
Xl might not be the name I’m thinking of but it’s like a 3rd category between photo and auto on some seedbanks
Maybe it’s super auto idk
No XL autos are just ones bred to be bigger and are typically longer flowering varieties.
And takes three generations to be full auto
Photo X Auto = Photos but “fast” sometimes just depends on genetics
Those produced photos crossed with themselves = 25% autos
And then those 25% that are autos crossed again to each other = 100% auto all cause its a recessive trait.
I’ve gotten to the 25% part just to see it first hand.
Greetings
One question
Let say that we cross two plants.
sat/ind(photo) X sat/ind/rud(auto), and then F1 x F1
In F2 generation is easy to determine auto plants. But what about rest of generation? How to know which is full photo, and which is heterozigotious?
Im not sure that flowering time can be good indicator, cos starting plants are hybrids, and in F2 there will be wide range of combinations.
Is there any other traits that indicate heterozigosity?
Is that rule? That it will start flowering with longer day then full photo plant?
Thanks
Is this the “right way” or more precisely, a “recommended way” to produce feminized seeds?
I read that pro-breeders stress a plant to prove a plant is not prone to hermaphroditism. If it responds to stress by expressing as a male, they toss it out as that indicates it carries the “hermaphroditism gene.”
If it does not, they call it “sexually stable” and use colloidal silver or silver thiosulfate to suppress ethylene and generate male flowers.
Here’s the question I have. ok, first generation all ‘fast photo’ but when you cross the two f1’s, of the average 75% photos, that comes from the breeding,are they all regular photos or are some ‘fast photo’ also or are they all ‘fast photo’?
25/50/25 is the general rule of thumb for F2s, and it should hold true here. 25% will be full photo, 25% will be full auto, and 50% will be a mix or “fast photo.”
