Ah, so you can just have a timer on to go on 16 off 8, then once they've been planted for about 5 weeks , then you can turn the lights off for 12 on for 12. Or black paper bag if outside? Also, once there ready for harvest, how exactly do you do it, Just go in there and cut ALL the leaves off carefully without pulling the bud apart? That kinda confused me too. Keep us updated with pics!
