Help Light cycles

Hi :)

I started growing 3 days ago. I have a question
seed is germinated but ı dont understand light cycle
I have 3 white widow seed please help me ! light cycle is
16\8 or 24 hours ?

18 or more hours light....your choice...18/6...20/4...24/0 for veg.

thank you :)

you need to have those lights about 2 inchs from the tops of the plant you also need more of them

thank you :)
this is my other growing picture
plants age : 2 month light cycle : 12\12 Day 4. :)

24/7 for growth for me but everyone different some swear by 18/6 but up too
you. Nice green growth Best of Luck

Drought

nice looking plants,
if you can have your lights on at night so then its lights of in the day time and it helps to stabalize the temps and humidity goodluck.:thumbsup::thumbsup::thumbsup:

I think the only reason for using 18/6 instead of 24/0 is the fact that it costs less...I've heard other reasons but none seem convincing

after 1 week later my plants it's look like this
I have a 3 white widow baby :)
light cycle 18\6
