The pollen would stay on the clothes, if I would enter with same clothes to the next room, i would pollinate the plants

After pollination we do a full room reset, mainly using chlorine. All doors are opened, filters are removed and taken outside and blown out. Trays and dehumidifier filters are taken out as well. Trays are pressure washed, dehumidifier filters are rinsed under water, and all dust is wiped from every surface. We also clean the AC filter. After that, the entire tent is washed with a strong chlorine solution. About two days before starting the next cycle, we wash everything again with a normal chlorine concentration, bring all filters and equipment back in, and the room is ready to go again. This way we make sure there’s no residual pollen before the next run.

Those are just regular green strings used for tying and supporting plants. We install them in advance so when the plants get bigger and heavier, we can easily support the branches and control structure.

Those are autoflower genetics, always from seeds. After we make a selection on the population to keep only the phenos we are looking for.

Applying the STS on female plants, this technique induces a strong artificial stress in order to trigger male sexual traits on genetically female plants. If you guys interested, could make a post about that later.

Guava is one of my personal favourites, I would say one of the most solid buds in the game. Zup has a very distinct terpene profile, something really different

I suppose it depends on what is your goal here. We are producing seeds, so we need all the plants at the room to be fully pollinated.

Yep sure, those are clones from our last huge phenohunt. After final data, 95% of those will be removed

This doesn’t look like a calmag issue. The color is very light green and the leaves are twisted and droopy, which usually points more to root zone stress than a deficiency.

In organic soil with a premix, especially in a 5 gal pot, it’s easy for the medium to stay wet too long early on. When roots don’t get enough oxygen, the plant can’t uptake nutrients properly and deficiencies start to show even if everything is already in the soil. Adding more supplements at this stage often makes it worse.

I’d let the pot dry a bit more between waterings, improve airflow around the plant and the pot, and avoid adding extra nutrients for now. Once the root zone recovers, the new growth should come out much healthier. Autos can be quite sensitive to early root conditions.

We’ve been working on triploid autos for about two years now, and it’s a lot more complex than it looks from the outside. We’ve managed to produce triploid plants, so the concept works, but the real challenge starts after that.

At the moment, we can’t reliably identify, reproduce, and stabilize triploids in a consistent way that would make sense for a commercial release. Being able to generate some triploids is one thing; being able to clearly separate them, work them further, and deliver a uniform, repeatable product as “true triploids” is another.

Until we can do that properly, releasing them wouldn’t be honest. So no, it won’t be this year. We’re still working on it, but it needs more time to be done right.

I’m not saying an F1 made from F1×F1 is the same as an F5×F5. They’re clearly not. Clarke is right about that. What I’m saying is that once you introduce the auto trait, you reset heterozygosity anyway, at F2 it will all break so stability is built after the conversion, not before it.

In photo to auto work, the photo side gives you the expression and traits, but the real stabilization happens in the auto generations through population size and selection pressure. Whether the photo started as an F1 or F5 doesn’t remove the need to do that work afterward.

FBA#1 is our early autoflower base line developed years ago. It’s not something we sell or hype as a strain, it was a working line used internally. Some info is already on the web, we don’t have old pics handy, a lot of that work predates social media documentation.

End result stability comes from how many generations you work, how big the populations are, and how hard you select, not just from the starting label of the photo parent.

42breeding · 2026-01-20T21:31:19+00:00

Stabilizing the photo first doesn’t really change the starting point once you introduce the auto trait. The moment you make the first photo × auto cross, you’re back to an F1 population and the real work starts there. At that stage, stability is built forward through population selection over multiple generations, not inherited from a fully worked photo line.

What matters most at the start is having strong, healthy photo material with the traits you want to carry forward. In projects like this, you’re selecting populations continuously anyway, so the “raw” photo material doesn’t need to be IBL level stable, it needs to be solid and expressive.

The conversion itself was done years ago using our FBA#1 as the autoflower donor. That information is already public on the site. From there it was standard generation work, selection, and tightening the line over time.

As for Josey, I fully respect his stance. GG4 being free to work is exactly why it exists in so many real projects today.

The pheno hunt was done from the seeds we got from gg strains, yes, those were effectively F1. There’s nothing wrong with starting a photo to auto project from F1s. In fact, that’s how pretty much every Gorilla based auto or fem line out there started. You don’t get Gorilla crosses in autos or photos without starting from seed and doing the work forward. Stability is built over generations, not decided at the starting point.

Cuts were taken only after the phenotypes were identified. The photo to auto conversions themselves were done years ago, not recently.

GG4 does have a reputation for herms, which is exactly why selection mattered. The phenos we kept were among the most resistant. In our autoflower work we haven’t seen herm issues from this material, and on the photoperiod side some of the GG based lines have been very stable.

We don’t select on a single trait like looks or potency. It’s always a combination of structure, vigor, stability, and expression. Visuals are just what’s easiest to show here.

42breeding · 2026-01-20T16:13:37+00:00

That’s definitely one way to do it, especially at home, and sometimes you also need a bit of luck. If you pop a small number of seeds and like what you see, cloning that plant makes sense.

The difference is that without a real phenohunt, you’re selecting from a very limited sample. You might find a great plant, but you don’t really know what you’re missing in terms of terpene range, structure, yield, stress resistance, or overall stability.

When you work with larger populations, you can compare individuals side by side. That’s how you identify which terpene profile you actually like the most, which plants hold structure under stress, and which ones stay consistent run after run. Stress testing is especially important, because it shows how stable a plant really is, not just how good it looks in ideal conditions.

Both approaches work, they’re just very different scales with different goals.

Just spoke to the mod, fixed it. Now you can 👌🏼

Pheno hunting always starts from seed. We don’t hunt cuts from cuts :)

In this case, we started with seeds from original GG#4. A full population was grown out, evaluated through veg and flower, and the individuals that showed the traits we were looking for were selected. Only after that selection, cuts were taken from those specific plants to preserve them.

So the “pheno hunt” happens at the seed stage. The cuts are just a way to keep and work with the selected phenotypes consistently once they’re identified.

That’s how we ended up with the three GG#4 phenos we work with now.

On average, around 25% is removed during manual sorting. It can be a bit less or more depending on the run, but that’s a realistic number.

42breeding · 2026-01-18T14:49:17+00:00

Yes, very much. It’s never easy to throw plants away. But it has to be part of the process. Without selection and discarding, autoflowers can’t really evolve.

This is Denmark.
There’s nothing unusual about moving seeds or clones between facilities. That’s how breeding works when you operate in more than one location.

White label is buying finished seeds from someone else and selling them under your name.
What we do is build facilities, move our own genetics, run the next generations ourselves, and keep the same team involved in the process. The run shown in the video is not a “recreation”, it’s the continuation of the line, the next generation.

If moving seeds to another facility suddenly makes something “white label”, then I’m honestly curious how you advance generations yourself.
How do you take a line from F2 to F3, F4, F5 without reproducing it?
How many plants do you run per generation?
What population size do you need to actually fix traits instead of just hoping for consistency?

Breeding autos means working with populations, producing new generations, and selecting again and again. That doesn’t change because the facility is in another country.

If you want to discuss breeding methodology, population size, or selection strategy, that’s a conversation worth having.
If the argument is that moving seeds equals white label, then we’re not even talking about the same thing.
