It's supposed to trigger flowering quickly by temporarily peaking levels of florigen, inducing the formation of sexual characteristics.

Will you see flowers a couple of days earlier? Yeah, probably...

Will you still be ahead by a couple of days at the end of the cycle? Less likely...

Will you see the same final weight? Probabley not...

Can be a useful trick to spot your boys quickly, though.
rhizome Reviewed by rhizome on . first 3 days of 12/12 ive read that for the first 3 days of your 12/12 cycle that you should give the plant 3 days of complete darkness before re introducing light. this somehow sets the internal clock of the plant to let it know to start flowering more efficiently or something. does anyone know?
