I never said they would grow perfect. I don't know what your getting at..
VPD Matters. allot actually. you will discover this after the years.
as you can see from my setup i have made everything my self, never purchased any ready made product, i even do the lights, automation, watering automation my self, so everything must be optimised. and btw this plant is on auto pilot, i never check, only every 3 weeks to fill the water tanks.
your plants are okay, they grow with no issues, but maybe its the strain that can withstand such enviroment, i had some sensitive strains before and this made me make things perfect.
bro even for the soil, i make it my self, including all the food, amino acid Phosporus, NPK, i make all by my self.

this is how my fridge usually looks when things are done. here 350 grams trimmed dry buds, 3 strains. 13 weeks flowering, 150 Watts total light.

My nutrition guide says 2 weeks before I feed proper nutrients.
And I was going to keep them in rock wool for 2 weeks and go straight to 30L pots.
Any help would be really appreciated guys
Why do you want 2cm of root space for 2 weeks?
They streched as fuck .more light and give her a normal container

VPD does matter a lot, especially if you have a lot of light on them its relative to demand, the more light the more anything wrong will show up, plants grown under low light have little growing pressure on them, its why in a jungle everything is so lush deep green , low light high humidity warm temps, plants are very adaptable to a broad range of conditions, but growth doesn't mean optimum a small grow is very different than a warehouse, you see guys that nail everything pull 3+lb per light, its not easy they dial in everything especially VPD, I could never get to 13 wks of flower mold would wipe me out, Im pretty much maxing out at 8-10 wks tops.

I had the VPD fairly close to right with these but a few issues with the root zone moisture, 4 plants 10x10 room 3600watts of light for 8.5lb dried weight, still only around a gram per watt but Im happy getting around 2lb a plant.

WOW this is impresive mate, thats a big grow op, in such a big grow manythings can go wrong and its harder and more expensive to keep things diled in,

i use dosing pumps to feed my plant and to control humidity, and i never have any issues, i do full organic, i water 10 times per day, 300 ML each time.

plants just love the scedule, and this schedule worked for me best, so i am not saying that my methods are the best, but this is what have been working for me.

plants are very adaptable to a broad range of conditions,
i usually try to avoid growing in summer, but when i do temps reach 38C lights on, im talking about last weeks of flower, so yes plants take it, but not a seedling with no true leaves.

Yeah same here it gets real hot, I run at night which helps but Im in the process of going sealed room and aircon, my walls and ceiling are fully insulated so I think with aircon and being sealed summer temps wont be a problem.
