Hey guys this is my first time posting so please be gentle with me haha.
I live in Ontario Canada and I have found I get the largest yield when I start my seedlings indoor and top them when they have 4 or 5 nodes developed. So when they go out you already have the new meristems established and I find they just take off, it could be different for growers in a shorter season like Canada but you Cali guys/ southern states dont seems to have those problems. With that said I have had success topping outside but they dont seem to yield as much as the ones topped indoors.
Cheers
