ive got 3 seedlings under 24 hour light and i want to change to 18/6 to try and stimulate more growth, they are 3 weeks old and only have thier 3rd set of leaves, barely growing in.
can i change them directly to 18/6 by turning the off for 6 them on for 18 and so on or do i need to do something else?
