Durring the lights on photoperiod yours plants run mostly on CO2. It is why some people supplement it to thier grows. BUT when the lights go out and your plants are in the dark or night photoperiod thier respiration reverses and they start using oxygen and putting out CO2.
This is why the ambient CO2 levels are higher at night then during ther day.
(this is the main reason people say they sleep so well when they visit "the country" in the summer. They usually say "the fresh air makes me sleep so good", in reality it's the higher levels of CO2 at night doing it)
Maybe you've noticed that the grow smell in a bloom room is usually worst about 1/2hr to 1hr after your lights come on, that's because your plants had a little extra CO2 to work with from the dark period.
See, get to learn something new every day. Your all welcome.
An old-timer once told me that if you take care of the roots, the flowers will be brighter, and smell better. (he was talking about roses) I've found nothing since then to dispute that insight. In giving light 24 hours a day, are we stressing the root system by not allowing the daily rest period it's had for 10,000 years?
My thoughts on dark periods: (not to be confused as fact) Cannabis genetics were not established in the extreme southern or northern hemispheres, where there is sun for three months straight. I'm guessing that since there has been an established dark period for thousands of years...the plant is using the dark periods for something. (plants don't sleep, do they? or perhaps they sleep during the heat of day, and work at night...? :wtf: )
And since the plant is drawing moisture to replenish plant respiration during the day, (and nutrients, carbs, carbon...) seems to make sense to me that it's repairs and growth are happening on the night shift.
-or-
It makes no difference, but was a nice theory.
Either way...I go 18/6 with healthy, consistent results. :thumbsup:
Yes, however wouldn't it be best to test tune his area. Just because MJ is c3 doesnt mean the area has the proper airflow, co2 ppm, etc to benefit from 24/0. I do it because I have seen the growth is much better with my setup.Quote:
