Amnesia Haze Automatic RoyalQueenSeeds

Just new week with first few pics with, about the right dates :D Watered 1ltr directly to pots (2,5dl each) with biobizz nutes and did some minor leaf removal and then some LST twist&turn* (*without any attacments) How long does it take for roots to reach the bottom of the container in numbers, to start absorbing water from the autopot system with high enough flow. Thinking if building own "autopot"system with current parts would work, where i could get the water higher up in the soil/pots
