i plan to go with 18/6 as a 1st grower and i have a little question. i'm using a small space, 50x50x80 cm, only 1 plant. my question is if i need to turn off the fans when i turn off the light or if they need to roll 24/24
18/6 is fine you can turn the fan off if you wish its best not to but i do as everythig is running from the same timer i normally do 24/0 or 20/4 until flowering what plant you planning on growing?
i would suggest doing 20/4 then 2 weeks before flower changing it to 18/6 to smoothen their transition,i usually subtract a couple hours a week when im gettin close to flower so as to not throw off their equinox intaking them from june to september overnight
