Growing Marijuana Outdoors – The Flowering Stage

The flowering trigger – darkness*

Flowering commences in cannabis when the length night time reaches a certain duration. The actual time differs from marijuana plant to marijuana plant but an estimate is twelve hours light and twelve hours night.

Be careful checking your garden after dark. Small amounts of light, even just from a dim flash light will stop the hormones that induces bud growth and the marijuana plants will regress to vegetative growth. If you should inspect in the dark refrain from using flash lights. Preferably go there in the day time.

Sexing marijuana

If you disposed of the males previously, then it’s mainly a waiting game. However, if the males are still present then keep looking out for them. (see also Early Sexing of Marijuana Plants).

Once you can figure out the sex, the male should be taken out to prevent it fertilizing female marijuana (unless you want seeds of course).

At the point male plants starts to show, within a short time the female marijuana start to show too. At this point feeding should be cut back and fertilizer used at 1/4 of it usual strength.

Cannabis requires plenty of phosphorus whilst flowering. Use a fertilizer that is greater in phosphorus levels.

* An exception to darkness triggering flowering in marijuana is a special breed of cannabis termed ‘auto-flowering’. Thes cannabis strains start flowering shortly after germination regardless of light and continue to flower throughout its life cycle.
