Hi
@Trala ! (just thought I would mention you!)
It looks happier, I will give it that. This whole way of working this HP is contrary to how I water with a strong wet/dry cycle though... you keep it wetter than I do... and it is my belief that this is what is causing the "wrinkles"... but what you are doing seems to be working for you and I don't want to criticize.
As far as roots trying to find their way out indicating the need to uppot... this too is not something that I subscribe to. I start out and stay for a good long while in a small cup, in order to form a rootball in the constricted space... you are racing for the next pot size... again, not exactly how I do things, but this is your party and I am here to observe, not rock the boat. You asked for a good reason though, so I will give you one. Your plant can not yet drain that cup of all the water in there in 24-36 hours, so the roots still have a ways to go before they are strong enough to
justify the need for a larger container. Moving her now will not make a strong rootball with lateral growth all through the container... you will end with a skinny root system that ends up mostly going up and down in the center of the next container with almost no lateral growth to the sides. The plant doesn't form an actual rootball unless you constrict her and make her do it. Staying in that solo cup until she shows you she has strong roots all through that cup is not going to hurt a thing. It may seem shocking to some of you, but I stay in the solo cup almost every time, all the way to the 5th node popping up, and it really seems to make the plants a lot stronger at the next stage to come out of the starting container with an actual root ball.
I appreciate the feedback, especially since I know our techniques vary a bit.
A few things I should mention-
I'm not in ProMix HP, I'm just in ProMix Potting Mix. It seems to drain well too, but I agree I keep my seedlings a bit on the wet side sometimes and would probably benefit from letting them dry a bit more.
Like I was saying, it's been a while since I up-potted anything. The last thing was my GelatOG
auto clone about 9 months ago.
Before that was a few years ago, when I'd let my clones go about 3-4 weeks in the cup (to node 4ish)
I realize that seeing the roots at the bottom isn't actually the the indicator here, I definitely want them to fill the bottom of the cup first and the plant be more established before it's moved.
I was going to move this a bit early (monday) because I plan on flipping it at about 30-35 days, and wanted the roots to be established in the new pot before I did that.
The last photo I did (ChemDawg 4) was started in it's final pot, and flipped at 30 days right around when the autos started going naturally. Due to tent size, that's about as big as I wanted it. It yielded 7 oz or so, and that's fine by me.
This one will be in a pot twice that size, so I want to be careful it doesn't get so massive it becomes unmanageable.
I'm lucky and am here with my plants most days, so I'm able to watch closely as they express themselves and their desires. Plant language is my second language (everything except orchids lol) so I definitely listen when they are unhappy for too long, and take note of what does make them happy.
I do pretty well with some of my unconventional ways, but I'm always open to hear other opinions and techniques.
Thanks for being here to share.
