What I’ve picked up on growing these varieties is smaller pots, lower nutrients usually but there are exception. Also higher humidity.
Lower nitrogen is common as it will cause many to extend flowering much longer or reveg/reflower, but there are exceptions that like heavy nitrogen in flower. To keep height in check many will flower from seed or small size. Also shortening the light cycle an hour or two has helped some, but others feel it lengthens the time required to finish.
I’m doing nld type for the 2nd time currently and have gone against the grain in all those tips. My soil is heavily amended, larger pots, plants were vegged for a couple months and I’m lowering my humidity as I have bld types as well.
What I have noticed, aside from the fact I have 2 different phenos, I have one in a 7gal and one in a 5gal and the larger one has stretched and spread out much more than the smaller one. It could be pheno but it could also be due to the root space available.
