20/4 is what is recommended by the breeders...they say anything over 20 hours is a waste of electricity...I think there is not a big difference between 18/6 and 20/4....at least i hve not seen a big difference in my auto grows yet...I was growing my latest White Dwarf under 24/0 until I saw it is actually smaller then the ones I grew under 18/6...I now hve the veg tent set for 18/6
