Indoor ? for AF vet breeders

[Monkeypox]

Have seen a few threads on turning a photo into an auto but can't seem to find them now . I have 2 strains I want to make fully auto ( Herijuana and Jackberry) . What is the right process to make the photo an auto ?

I would like both of these as autos since both are strong ( one couchlock the other a daytime smoke) . And both are normally early photos to begin with ( usually 7-8 weeks ) .

Just looking for some input on the best way to get these two to be autos .

try and find an auto with similar traits, it makes the cross easier... then cross them... and select for the pheno you are after... in the simplest of terms... maybe check the autoflower knowledge base... there must be some info there about this in there.

Do you want to make to make a cross and inherit some characteristics like flavor or high, or do you want to recreate it in auto form?

Basically, you want to use an autoflower that is already pretty close to the photo in indica/sativa. If you're trying to recreate a haze photo in auto form, is gonna take longer if you breed it to an auto kush compared to an auto sativa.

You want to ideally grow out a good amount of the plants so you can find those that you think best represent the traits you want to carry on. After you make the cross, this will be your f1 generation. At this point you brother-sister breed the f1 to come up with the f2. This is most likely where you will see your first autoflowers, but, if you're magical like Wiz, and grow enough, you may see autoflowers in the f1.

At this point, you can keep inbreeding the line to select for plant structure, effect and flavor, or you could take a fully auto offspring and cross it back to the photoperiod you want to mimic.

The basic point is that the autoflower gene is recessive. You have to inbreed, usually to f2, to find the gene again in offspring. In some extreme cases you will see autoflowers in f1 and this is if the parent photoperiod has autoflower genes back in it somewhere, or if it has been inbred for the earliest to show flower for many generations

Essentially I want to make each strain an AF , trying to keep as much of the traits of the photo side . I have done a lot of breeding with photos , but autos are something new to me .

Looking around using my google-fu to get as much info as possible before I start this project . If i can get this going the right way I'm going to do a grow journal with each step and each progression .

Looking forward to your journals.

have you ever considered grafting a autoflower in veg
to your favorite photo in veg..
theoretically the auto would transfer the flowering
hormones to the photo and induce earlier flowering
and you still get to keep all the good traits you like
in the photo without several generations of selection
and backcrossing to the desired traits..
now I have NOT personally tried this but,
cannabis takes to grafting well,so I can't see any
reason for it not to work...

First off as some talked about what are your goals ?

Are you looking to make a new AF cross or have a Jackberry that AF's ?

This is why I liked using Lowryder in crosses because it was so unassuming on the other strain used in the cross. Sure they are smaller in stature ( its called breeding not pollen chucking ) but if you create a new AF like your going to do you'll have a new AF cross strain then take it back to the original 12/12 strain that you liked like the Jackberry. Do the process all over again using the new Jackberry cross thus making yet a new AF strain that more closely resembles the original 12/12 strain and do this 3-4-5 times ( this is where you decide if you are a breeder or chucker ) and you'll get a true representation of the original strain.

Goodluck

SaH , goal is to have each strain ( Herijuana and Jackberry) as an auto , retaining as much of the qualities of each , just in auto form .

From what I understand , and what I have learned breeding photos , I know I will have to do an initial cross . The from the seeds of that cross pick out the plants that have picked up the auto trait and use those to backbreed . Then use those seeds and pick the best that show autoflower trait and use those again with an auto male . Somewhere in between it may come to inbreeding etc .

For photos I basically started hundreds of plants to find the best few that showed sex earliest , and cropped soonest . Inbred those for a few generations then back crossed with an early male from the original run . Continued this until my harvest time went from 1st week of Oct to beginning of Sep . While also stabilizing the plant stucture and potency .

Having said that , I am wondering if the same way can be done to convert H and JB to autos .

Back crossing in the world of autos is usually a shortcut if back crossed to the auto. That is because, generally speaking (and i mean GENERALLY, because this is now being turned on its head. see LBH strains and a strain called supersonic crystal storm) autos are less potent than the photoperiod. People can back cross the f1 to an auto to get 50% auto in the offspring, but they reinforce the autoflower characteristics such as lower potency and less taste/aroma.

Inbreeding is the best method because of the amazing diversity opened up at f2 and f3 due to recessive phenotypes showing up. At f2 and f3 you will find plants that are MORE potent (as well as those that are less potent) than either parent were. This is a statistical certainty.

Potency is inherited as a bell curve. The most potent and least potent will be the least common. Therefore, parents with a larger difference of potency have a larger standard deviation, and a greater potential for evolutionary change each genertion. You just have to grow more plants to find the best. Back crossing to an autoflower narrows the median THC content, and therefore how far the median is likely to move each generation.

Once you inbreed your f1 you will see about 25% autoflowering in the f2 generation. This means crossing an f1 male to an f1 female. The selection at the f2 is critical. This is literally the single most important selection point for the overall potency, flavor and plant structure. If you do good here you can save yourself several generations of stabilizing. 1/4 will autoflower, but that tells us nothing about their other traits. If you are looking for autoflowering AND herijuana taste, you are at 1/16 plants with the correct combination of traits. If you look for 3 traits, and all those traits are recessive, 1/64 will have what you want. Then you have to find the male.

If you aren't familiar with them already, check out a video on youtube or something about punnett squares and Gregor MEndell. Those are where my figures come from in the post above. They provide a way for us to visualize a cross and give us probabilities for what to expect on each generation.
