    hours is growers preference for vegetative stage. you can run keep em on 24 hours or 18hrs light and 6hrs dark. its your choice. when you flower its 12/12. my preference is leave em on 24 hours a day on cfl and 18/6 when i use a mh

    you can do 18/6 when ever you want. you can even have that light regiment starting seedlings. it is only highly recommended to keep clones under 24hours, but 18/6 will do too. myself i was using 24 hours with my mh with bigger plants but now im going to switch to 18/6 cause my electric bill is getting really high. but when i use my t5 at start of seedlings or clones i will use 24hrs cause t5 take less electric. just remember

    vegetative stage : 24 hours or 18/6 - whatever your preference is. some people say there is no noticeable growth either way and some say there is faster growth with 24 hrs cycle.

    Flowering Stage : 12/12 - you only use that light cycle when you want to start to flower. mostly done when the plant reaches atleast a foot tall but will get a better yeild if wait till you see pre-flowers

    ** just dont keep switching back and forth from 24 to 18/6 and so on. it will cause light stress causing it to herm.

    A plant sleeping is always so cool to see.

    I go outside to the garden in the dark of night... it's a trip to see the whole garden sleeping.
