the only reason not to repot them is if you damage the roots it wont recover if its a stress less transplant then it will just keep on going there is a point when it will stunt them if left in the smaller container too long
they love rotation , lst , pinching FIM it if it stretches to much
i can show you a grow that the dude pulls pounds in a scrog from like 6 think differents and repeats the setup over and over he pinches the hell out of them

it all boils down to your skill level
they really just dont like rich / hot soil from the start and give them as much light as you can i run mine 24/0 after growing just auto's for a few years now in a 3x4x5 box with 400 hps and 270 w of led
