i just started topping and lst, but i was told to start as early as possible, before the main stem hardens so by the 3rd or 4th node id say u can maybe go six nodes so long as the stem hasnt gotten to woody..im also just starting to try monstercropping to avoid the topping and lst or hst. ive been told using the monstercropping method i can get multiple colas without all the topping and bendeing in roughly the same amount of time..more time rooting, less time in veg were lst is faster to root but a longer veg time to let plants recover after training..like i said this is new to me so any info would be aprecciated.
