18/6 for veg and 12/12 for flower. Plants need 12 hrs of sleep in flower cycle. The bestt time to have your lights on is up to you, my timer is set during the cheap energy hours!

I've read in a bunch of places that 24/0 is the best to start your plants off with in veg, and then obviously 12/12 for flower..

Most will say 24.. then 12/12 flower... I did 18/6 for veg... worked great... 17/7, 16/8.. as long as the cycle stays the same...... I do it for sleep reasons..
12/12 flower ....

I believe that the vegging plants need a rest period. 18/6 is good.
12 /12 flowering Make sure the dark period is uninterrupted.
Twistyman taught me everything:)

Some people grow at 18/ 12...The possibilities are endless it is like the lottery. I do not like to gamble much so I would stick with what works for me.:)

18\6 promotes better root growth than 24\0 but both work fine and anything in between

12\12 flower no acceptions unless autoflowering strain
