Hi all I'm curious what all your thoughts on light time for vegging. Who uses 24/0 and who uses 20/4 do you see a difference? Whats your experience? I like to go for a few weeks 24/0 then switch slowly to 18/6 and finally to 12/12.
I always use a 20/4 light cycle for veg. Plants do have a net release of carbon dioxide at night due to cellular respiration. Both animals and plants undergo cellular respiration constantly. However, in the light, plants produce much more oxygen via photosynthesis than than they consume in cellular respiration. Im also in favor of matching a more typical nature cycle.
