dunno man its up to you. personally, im gonna do some experiemntation with just topping now, coz LST can take more time. plus if youve got a strain like a 100 day auto, the plant should bbe able to recover from topping in plenty of time anyway, then youll have 4 main colas and the effort you put in is next to nothing. you could do some experimenting yourself too, like topping one and lst'ing another, if you want. personally i dont have the luxury of being able to spend lots of time tending to my plants in peace. I always gotta b on my toes like a ninja
