Cannabis does not need any darkness during veg. That is a myth. Your *environment* may need the 6 hours of downtime, usually due to inadequate ventilation, to provide some time to cool down, but the plants do not. 24 hours of energy beamed at them during veg just makes them grow faster. If you don't like the speed at which they grow and wish to slow them down, or your ventilation/temps are inadequate to handle 24-hour lighting, then 18/6 makes sense.
If you search these forums, You'll find that some-one did the experiment to test that. There conclusion was that 18/6 actually produced a larger root. Larger roots = Larger plants = Larger yield. :smokin:
Not to be picky or anything but I was under that same impression until the results. :rasta:
