So far, I have had no issues.
I am checking ppm and pH daily and adjusting pH every second day.
Ppm hasn't gone down once and there are no roots visible yet.
My air pump for the air stone in the bucket is at a constant 100% and the water is submerging the small pot with the clay pebbles by around 1-2cm.
I switched on the fan in the tent because I think it will help me with the temperature in the tent. For that reason, I also took the air pump and set it up outside the tent.
The water in my bucket had 26 degrees Celsius, now it's on 23.
The whole bucket will be replaced once a week.
