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.
When determining the sex of a cannabis plant, pre-flowers, or the beginnings of male and female sex organs, will appear at the nodes.
Because of this, it’s important to look into the genetics of the male plants. Their shape, rate of growth, pest and mold resistance, and climate resilience can all be passed on to increase the quality of future generations.
A node is a point at which a branch grows off of the main stem, or one branch from another branch. Fan leaves and buds can grow on some nodes, but not necessarily all.
Cannabis plants show their sex by what grows in between their nodes, where leaves and branches extend from the stalk. Pollen sacs will develop on a male plant to spread seeds and stigma will develop on a female to catch pollen. You can see these differences weeks before they actually start serving their purposes in the reproduction cycle. These are known as “pre-flowers.”
Because this occurs when cannabis is under stress, it’s important to monitor plants after they have been exposed to stressors: indoors, high temperatures or light leaks are often the cause; outdoors, a snapped branch might be repaired and then turn into a hermaphrodite.
Mycorrhizae, a beneficial fungus, can be added to soil to improve root systems.
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.
Top feminized cannabis strain families
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
Male cannabis plants are normally seen as something undesirable, at least if you ask the average cannabis grower. No one wants their precious crop accidentally pollinated and then ruined, as we’ve learned will happen if we don’t separate the males from the females early on. This negative stigma and the hassle associated with male plants are the reasons that feminized seeds have gained popularity. It’s true, they do make things easy on the grower.
Many hobby growers use one single feminized strain, or base their entire grow on essentially identical clones.
CAN YOU SMOKE MALE PLANTS?
When you start breeding your own top-shelf bud, the male will contribute 50% of the genetic material. It just makes sense that you’d want to select the best male that you have as the donor.
This lack of diversity leads to weakened defences and an increased sensitivity to diseases and pests.
You don’t always need to smoke cannabis to get some good use out of your plants. Cannabis plants have various natural defences, including their aromatic terpenes, which are great pest repellents. Cannabis really is an excellent companion plant. A few strategically placed male plants between your veggies may be all that’s needed to keep them pest free, without having to use potentially harmful pesticides!
