outdoor north there is already +18hours daylight in may i think july it start to go under 18hours about and between it can rise up to 24hours so its beneficial for me outdoor
veg them first 1-2months indoor on 21hours cycle =) root stress can show if its male of female but did not happen me much this spring only one did that and it have some autogenes on that line and it was male
and really fast male maybe it root stressed it to ''flower'' or it was auto..
most of i can veg without showing sex for month easy i have not tried so long becouse small pots..
autos i veg only to first 2 or 4 pair of leaves i think 4 is too much if its picky and root hit the bottom of pot it start to flower lol
fastest phenos might even flower at 19hours daylight lol
on midsummer its 20-22 hours daylight on south and 24 on north
i think the terms should discribe it hole world not just latitudes that dont have as much daylight
i do some exprimenting next spring i put couple on 10-20litre pots and veg them like 2-3months before putting outside?
then they veg like 2-3indoor and 1-2months outdoor? sure not auto then xD
for sure they are not maybe beneficial for all but short northern summers or high altitude growing might be perfectooo or if you want crop middle summer somewhere it start flower when you put it outside becouse lack of daylight hours lol
