Flowering phase Cannabis cultivation



a flowering cannabis plant


inflorescence produce no seeds called sin semilla (which translates without seeds in spanish, , misspelled 1 word). potent sin semilla important medical users, minimize amount of cannabis must consume afforded relief. cannabis seeds considered of inferior quality and/or grown inferior technique. cannabis grown induced flowering decreasing photoperiod @ least 10 hours of darkness per day. in order initiate flowering response, number of hours of darkness must exceed critical point. more hours of darkness each day, shorter overall flowering period lower yield. conversely, fewer hours of darkness each day, longer overall flowering period , higher yield. traditionally, growers change plants lighting cycle 12 hours on , 12 hours off since works happy medium strains respond well. change in photoperiod mimics plant s natural outdoor cycle, 18 hours of light per day in summer , down less 12 hours of light in fall , winter.

some semi-autoflowering strains have been bred exclusively outdoor use, particularly in outdoor climates such of uk, start flowering as 16–17 hours of light per day. can start flowering in july , finish far earlier other strains, particularly haven t been bred outdoor strains. semi-autoflowering strains can harvested before weather in northern latitudes becomes wet , cold (generally october), whereas other strains finishing flowering, , may suffer botrytis (grey mold) caused wet weather. alternatively growers may artificially induce flowering period during warmer months blacking out plants 12 hours day i.e. covering plants black plastic example, excludes light during period plant can flower during long days.


although flowering hormone in plants (including cannabis) present during phases of growth, inhibited exposure light. induce flowering, plant must subject @ least 8 hours of darkness per day; number strain-specific , growers use 12 hours of darkness.


flowers plants (e.g. cannabis) called bract/bracteole, , (with cannabis) prized part of plant. during late period, bract/bracteole visible naked eye. bract/bracteole development begins approximately 1–2 weeks after photoperiod reduced. in first weeks of flowering plant doubles in size , can triple. bract/bracteole development ends around 5 weeks flowering , followed period of bract/bracteole “swelling”. during time buds increase in weight , size.
