PC Grow box 1st timer

whats up guys? i have a pc grow box a pretty legit one i got off the internet. i order some automatic seeds. how much lighting should i give them? 24/7? 20/4? 16/8?

* 18/6 for veg and 12/12 for flower is the most common use, I hear autos can survive * 24/0 and 20/4 but that it is best to stick to 18/6 and 12/12, also you could do 12/12 from seed if you wanted to.

I would go 18/6 and being autoflower then dont worry about any other light cycle as the name says it all. If reg. seeds the best cycle would be 18/6 then 12/12 like RRain said. After 2 weeks+ of veg. at 18/6 then you could go 12/12.

i have g13 northern lights auto and dinafem roadrunner #2 auto that i'm gonna get around to..both companies state in the descriptions of the strains that 20/4 is ideal for autos
