HYDRO Is this an acceptable growth for a 16 days feminized White Widow?

I've rooted it in a natural sponge plug, waited for a dozen of roots to get off the thing and transplanted it in a 5x5cm (2"x2") rockwool cube. Now first roots are coming off the bottom of it.

Is this average for an "hydro" grow? It will go in a drip clayballs system once the cube is covered in roots.

I use the classic GHE flora trio + Mag Cal (since I use RO water) + B'cuzz Root Stimulator. Ppm 600 and ph 6.0 on the last feed, photo taken immediately after.

Looks good. Who was the breeder on that WW seed you got?

[MithrilSCYTHE]

Royal Queen Seeds, 10 seeds bought this spring, I had the last 3 to pop for this winter, 2 germinated, this is the best, the other is slightly smaller but almost unnoticeable

Hi Mithrill, She looks hale and hearty, but might need a little bit more light intensity so she doesn't stretch out too much and get too gangly. I love RQS seeds. They are always winners.

Hah, I know that feeling. But it's what you told, an hobby, I'm not really a stoner, I like to relax sometimes but generally I just give away almost all my productions during reunions with my friends, I like to grow though, and cannabis is an extremely beautiful plant and it's so satisfying to grow.
I also like chemistry, and hydroponics join my passion for that and gardening.
And obviously the results are funny 😉
I don't consider in spending too much, just the bare minimum but I'd like to have everything.
My tent is regulated by Arduino automatically, so I can optimise even if I have a shitty heater and dehumidifier 😁

I had to look up Arduino, but I didn't understand it. Can you explain how it works?

[MithrilSCYTHE]

It's a programmable controller.
It's turns on and of electrical plugs in my case.
Based on temperature, humidity, hour of the day.
I control the lights, the extractor, the pump... And now heater
