Might as well stay at 18/6 ... I'd love to know the science behind flowering and if more hours of light grows bigger buds ...
@Waira @stepside ... what would be your thoughts ...
My name aint stepside, but I can let my ideas fly. Hopefully I I'm not too confusing, I'm going on memory rather looking this up.
What is happening in photo plants is this:
There are two bits of stuff in the leaves that are related to creating the hormone that initiates flower meristem development. COnstance protein and one more (i forget its name) but they have a negative correlation, and CO is only created during the light part of the day. When the day length gets short enough the CO protein stops being present in quantities to suppress the other chemichal, which starts innitiating the DNA to create "Florigen" This happens in the leaves, and florigen is moved through the vascular system to the growing meristems. This is where the change to flowering happens. The leaf meristems undergo a change in the presence of florigen and start creating flower parts.
This is how it works for "short day plants" What starts the trigger to flower is actually the long night period. CO protein is the plants time clock.
It is very simmilar for "long day plants"
It is COMPLETELY different for Autoflowers or "day neutral plants"
The mechanism to induce flowering in day neutral plants is not consistant or understood. It is species dependent, and the best advice I have gotten from plant biologists is that you can only say that they will flower when biologically prepared to do so... which is saying nothing.
I would LOVE to know what is triggering florigen in an auto. Hopefulle
@Waira or someone will set us straight.
