Need help with a few Questions

[oldmac]

I use 24hrs but have read that 18/6 is best after seedling stage..something to do with the dark period allowing for more energy to be expended in root growth and not focused on Photosynthesis as with light on. Although I am always a novice grower looking to better my garden. :thumbsup:

Hello OldHead09,

Sorry to tell you this but; Roots grow in the dark but not when it is dark.
Roots only grow during the photoperiod, that is the reason most people root cuttings using a 24/0 photoperiod of low level blue dominate light.

BTW, the "root cap" of tap roots do continue to divide cells even during the dark period but this is producing a lubricant for the tap root to use when it does grow.
