If you want your marijuana plants to start pre-flowering just change the light cycle to 12 hours on and 12 hours of complete darkness. Why does this work, well letâs think about how plants are in their natural environment.
During the vegetative phase your plants will establish a solid root system and full leaf development to prepare them for the final flowering phase, the actual marijuana buds. Marijuana will stay in the vegetative growth cycle if it is given anywhere between 18 and 24 hours of light per day. The vegetative growth cycle is usually only two to four weeks long in most indoor strains and will be completed in the third to fifth months of growth depending on the marijuana strain and conditions. The marijuana plant can only grow as fast as it can produce energy required for new growth.
