Branches grow out of the main stem and support fan leaves and buds. Growers often train a cannabis plant by topping branches to create more bud sites.
However, cannabis is primarily cultivated for buds, not seeds, so the practice of growing sinsemilla, or “seedless” cannabis, is prevalent today: Females and males are grown separately, or males are even discarded, to prevent pollination. This allows female plants to focus their energies on bud production instead of seed production.
Male vs. female marijuana plants
Examine the nodes of the plant and look for either the early growth of small sacs on a male, or two bracts on a female, which will eventually produce the hair-like stigma.
In the wide world of weed, the female of the species is more useful than the male. The marijuana plant is like many other plant species in the world. It needs both a male and female plant to reproduce (it is a dioecious species). Admittedly, there are self-pollinating cannabis plants (i.e., monoecious plants). In general, however, most marijuana plants express female or male-specific sex organs.
1 – Breeding Cannabis
As a beginner, you have the option of cloning the mother plant and creating a ceaseless line of consistent buds from identical female plants. However, as you become more skilled, you will begin to find flaws with your bud. For example, you may want it to be more resinous and potent. Alternatively, you might love it if the flowering stage ended a bit sooner.
2 – Use Male Cannabis Plants to Create Hemp Fiber
Since you can’t smoke a male plant to find out how good it is, you must go through a different process to find suitable genetics.
But ANY 12 hour dark period will work, as long as you prevent your plant from getting light leaks during their “night.”
How to Determine Sex of a Marijuana Plant
Regular marijuana seeds will be 50% male, and 50% female. That means half of the seeds will be unusable as far as growing buds.
You can wait until your plants naturally show the first signs of their gender and then remove all the males, but that means you have to watch the plants closely. You also will waste time and energy growing plants only to find out that some or all are male and have to throw them away. If you want to be more proactive and get rid of all male plants right away, then use this technique.
You can also make your own feminized seeds, but you have to start with two known female plants.
Sometimes it takes a day or two for a female pre-flower to release her first pistil, and the female calyx can look like the beginning of a pollen sac. Generally the more “pointy” ones tend to be female, but sometimes you have to wait and see a few more flowers to know for sure.
