I would have to agree with LetsSeeya. I ran 18/6 on my first grow and on my current grow I am running 24 hours of light. If I wasn't dealing with the cold issues I have and didn't need the light to be on to take care of these issues I would definetly run a 18/6.

I feel like the plant has alot of things going on during its night period and just make the girl that much better. Could be just me though!
