I am curious if anyone has ever done a side by side, putting one plant from 18/6 to 12/12 and giving another plant 24-36 hours of uninterrupted darkness before the swtich. The darkness between veg and flower should make the plants flower quicker. What I want to know is does this have an effect on the over-all yield. Do you get higher yields because the flowering starts quicker, or less because the plants might not stretch as much, or is the difference negligible.
Flowering in marijuana if regulated by phyotochromes, of which there are two isoforms (states), Pr and Pfr. In uninterrupted darkness Pfr is converted to Pr. In the presence of light in the red spectrum Pr is converted back into Pfr. Once a certain level of Pr is reached the plant begins flowering. The theory is if you give the plants 24-36 hours of uninterrupted darkness before flower you build the level of Pr above that certain level kick starting the flowering.
I am planning on doing a side by side test in the very near future (probably 5 weeks before my clones go into flower). I am just trying to get some preliminary information. I know there are some growers that already do this. If you are one of those growers please share your experiences.
