i have clones at 4weeks veg under a 600w at wot week would u recommend i switch from 18/6 to 12/12Well, myself...if I start from seed, I like to veg 8 weeks.
and in that time, I usually top, and train, and tie down.
then, when I make the switch, it's more bushy when its flowering, than tall.
that is in a grow tent. When I do outside grows, I usually just let them go naturally.
