Generally, cannabis plants start flowering when nights – dark periods – are longer, which is a sign to show their sex and start blooming. Actually, marijuana plants reach their sexual maturity between 6-8 weeks after seed germination , regardless of the photoperiod.
As we mentioned before, when plants are about 2 months old – when they have 5 or 6 internodes – they are sexually mature, which is to say, they have set their sex. In some cases – most of them produced by stress – plants will show both sexes, being what we call hermaphrodites, but generally at this moment plants show their true sex, that will mantain for their entire life cycle.

It is this fact what can help us to determine the sex of our marijuana plants without the need to make cuttings or change the photoperiod, what could strees our young plants.
What we don’t recommend at all is forcing the flowernig of mother plants for a few days/weeks and once they show their sex placing them again with a growing photoperiod (18 hours of light/6 hours of darkness), since this will produce major hormonal changes inside the plants, being an easy way to stress them – what will improve the chances to get hermaphrodite plants.

This technique of premature detection of the sex needs a little practice, but once mastered it will allow us to determine the sex of our cannabis plants at a very early stage.
If we can’t sex our plants with this technique, we can take a cutting from each of our marijuana plants and flower it in a growing tent – 12 hours of light/darkness photoperiod – what will force it to flower and show its sex, that will be exactly the same as its mother plant.
Marijuana plants can be males, females or hermaphrodites (both sexes in the same plant). Female plants produce buds, the richest part of the plant in
We don’t smoke males, so it’s harder to find the perfect plant with the best flavour. Usually, breeders select their male through process of elimination. Here is some criteria to help you determine which one to keep, and which to discard.
This lack of diversity leads to weakened defences and an increased sensitivity to diseases and pests.
Who knows, you may at some point want to get started with textile making! This is definitely another area where you would want to keep your males, as they are especially useful for certain distinct purposes.
Eliminate those male plants with an airy bud structure and keep those with dense and tightly-packed buds to ensure good yields.
There is a distinct difference in the type of fibres that male and female cannabis plants produce. Farmers normally separate them when they desire different plants for different uses.
A simple sniff test is yet another easy but effective way to find a promising male. Keep those plants that have the best scent.
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.
You can also use your male plants for those very same purposes! Most of the resin in males is located in the sepals and those locations where pollen is produced. There is also a good amount of THC in the small leaves. No reason to toss out all this goodness!
Some see male cannabis plants as nothing but an inconvenience, if not a threat to their crop. In reality, male cannabis plants display some beneficial uses.
