Week 28 for my crimea blue plants.
They perform well and reacted good to switching from veg into bloom.
The buds got a lot bigger and now they have go get sticky.
Stay tuned.
Kickass.
I'm pretty sure you'll get really large plants there. Even with just 60cm space for some plants I grew (with all kinds of random stuff growing around them too), some of them reached almost 4m.
Dunno if this is relevant to you, but I'd think about gradually adding more soil, like mounding the plants too, so that the existing horizontal roots are a bit more protected, some can die off and new ones can get generated in the added soil.
Best of luck.
@BigBomber,
Well, I wouldn't say more soil is *needed*, but I think it makes the plants grow better/more effectively (if you use nice decent soil or mulch/debris, at least) and it's really simple/cheap to do if you can do it (obviously you can't with pots), although a bit of effort.
In terms of timing, just gradually, a little bit now and then, not like heaps and heaps of soil constantly, but maybe a few centimeters every 2-4 weeks or roughly the equivalent of that. It's not exactly a precise science. Sometimes more, sometimes less, depending on regularity and conditions I guess.
The reason I suggest that (other than having done it and it seems to work well, extra cold protection, extra microbes, extra nutrients, etc) is because of this image of cannabis roots, from a large plant:

You'll notice the vast majority of the root mass is actually near the surface and horizontal. I assume the vertical roots are more for water uptake or harder to find minerals.
I also gotta tell you, there are SOME drawbacks to having massive plants. My plants aren't THAT large, but they're still difficult/annoying to manage and inspect. I would seriously consider fimming in general in the future to restrict height without too much loss, if there's available space, since it's very little one-time stress on the plant.
But ideally, you wouldn't have to, if you can manage that shit, don't bother with the stress/training (except for helping out the plants).
Height should not be a problem at my spot :) but the higher the plants are the more difficult is the inspection that's right...Maybe I am gonna do some height control to them when they start to grow more in the first flowering weeks.Thanks man, gonna read sth. about that
Oh yeah dude, somehow forgot to mention this even though I mentioned it on my diary. But I was reading about this stuff called beta-cyclocitrical, related to carotenoids, it's like a root growth hormone found in many plants, apparently.
But anyway: https://phys.org/news/2019-05-hormone-root-growth-agricultural-tool.html
Might be useful or worth checking it, for future reference.
For the ghetto-method inclined, I would almost wager you could just use some plants/fruits/vegetables high in beta-carotene as feed, or in a tea, to get some of those effects.
Edit: So I checked it out a LITTLE bit, kinda hard to find good info on that, but I was quickly drawn to paprika, especially bright yellow and orange paprika. It might really be as simple as using something like paprika as feed...
