Is it required to grow a clone in a small pot, then transplant it to a bigger one, and then transfer that one into a bigger one when it's big? Can't I just grow the clone in a big pot from the beginning? I want to grow my plants to 3ft, meaning that I should need 3 Gallon pots eventually? Can't I just plant the clone in a 3 Gallon pot? And if I can't, why not? Does it affect the growth speed, or is it because I'll be wasting nutrients and water?
