Slt mon nom est kaizer59 je suis en train de faire de la northen light auto je suis a ma 3ème semaine de croissance je voulez savoir a quelle moment je devrai changer mon ampoule pour la floraison ?merci
as soon as you start seeing the flowers appear, right before the buds start.
with an auto you should start seeing some thing in or around the 4th-5th week, this is when you change to the other bulb.
hope that helps
