Xabii Did some changes to the setup namely changing to upper box to a smaller one for easy access to the reservoir, moving the air exhaust outside to gain some more space, 4 tubes instead of 2 to the top for a more even watering, light protection around the cubes to prevent algae, added a T piece to the pump with quick connect so that I can easily plug in a hose and empty + refill the reservoir.
Also calibrated ALL probes at the beginning of this grow, including the EC probe which I did not last time.
Added a smart plug to the air exhaust that activates when RH is higher than 65% it goes on and lower than 60% it turns off, will use that for the first couple weeks to raise RH inside the tent because I have a 120mm fan blowing through the reservoir to cool it down which increases RH.
No Worries early on because the exhaust being off for a while is not bad since the plant does not smell yet and doesn't need as much fresh air as later on.
Soaked the seed in water for 23 Hours, nothing showed yet, placed it in to the Rockwool.
More Info in coming soon.

Xabii Plant is doing good, average to good growth for 7 days.
Setup works just fine, did water twice with a cup directly in the middle, probably not needed but better safe than sorry.
Switched from 24/0 to 18/6.
Lost timelapse footage of day 6.
Values are average of the day.

Xabii Plant is doing average to good for 14 days.
Did not increase much in height but expanded in width and shot some side nodes.
Did top her on day 14.
Found a few Thrips so I ordered predator mites, can never get rid of these due to surrounding trees next to my place.
Values are average of the day.

Xabii Plant is doing OK? for 21 days?
I am a little unsure because she is simply not stretching but growing good on the side notes.
After some discussion on /r/Mephheads I came to the conclusion that I will try to lower the DLI so that the plant stretches because for now there are way to many nodes way to close together.
Received my predator mites and added them (the pouch).
Increased EC at the end of the week with Universol (high in P) and added some water to the reservoir.
Heatwave is coming so next week will be hot in the tent, no way around that.
Values are average of the day.
