I have three plants 24/0 under 8800 lumens (63.6% Daylight / 36.4% Soft White) and I am going to move them to a new box that has 12800 lumens (100% Soft White). I want to keep vegging them before starting flowering. Will they continue to veg under 100% soft white and is it possible for them to begin flowering just from the color temp change?
you're fine. red spectrum can carry you from seed to harvest. it's the schedule that makes the change.
