I have LED grow lights (600W Viparspectra dimmable) and on the instructions it says to do 12/12 during the seedling stage and switch to 18/6 during vegetative, however I heard that you’re supposed to do 18/6 during the seedling stage. Should I do 18/6 or should I follow the instructions and do 12/12? Also how do I know when it is officially the vegetative stage.
I’d go with 24/0 lights on at the start till the seedlings get a bit of size. After a couple weeks drop back to 18/6.
You only do 12/12 when you are ready to flip to flower.
Thanks guys! So just to be clear, even though the instructions on my grow lights say to give it 12/12 during seedling stage, I should give it 18/6 anyway right?
