Photoperiod Cannabis

In our photoperiod cannabis strains section you can look up photoperiod cannabis seeds and find fastest plants with the shortest flowering time.  But what does 'photoperiod cannabis' actually mean? Unlike autoflowering marijuana plants, photo period marijuana starts flowering when the outdoor or indoor light cycle is changing: days get shorter or you switch from 18/6 to 12/12 hours of light and darkness. It's a signal for marijuana to go from the vegetative into the flowering stage.
