I believe I am at 1 month of veg time (from seed). What I need to know is how much longer to wait to switch to 12/12. Also I attached a picture of my attempt to trim a plant (One_Month_Trim) to create 2 main branches. Did I do it right? I hope to flower using three 42watt CFL and one 45watt CFL in a closet scrog grow. When should I add the screen?
