As anyone with seasonal allergies can attest, it only takes a little bit of pollen to have a big impact. The reason that growers are so intent on weeding out male cannabis plants is that a single pollinator can negate an entire potential harvest.
After a period of several weeks, the plant will begin to pre-flower, or form a small bud in the crux of a branch. One of the first signs your cannabis plant is female is the appearance of pistillates that are wispy and generally white in color. Male plants will instead produce pollen sacs that look rounded with distinct splits running lengthwise, a bit like a tiny crab claw. These are the structures that growers typically look for to determine a plant’s sex.
What Are Feminized Cannabis Seeds?
All of those male plants will have to be carefully separated from the grow space and destroyed, or else the growers risk another disastrous accidental pollination. It takes minuscule amounts of pollen to pollinate a plant, so growers must take extensive precautions to eliminate potential contamination. In addition to helping mitigate other contaminants, this is one of the main reasons that many workers will don full-body suits when working in a grow room, ensuring that accidental pollen exposure is kept to a minimum.
Separating Male and Female Cannabis Plants
Cannabis seeds can be male, female or hermaphrodites. Females produce the resin-secreting flower, and males make small sacs of pollen near the base of the leaves. Over the years, cultivators have learned that un-pollinated females (remember, males produce pollen) continue to make resin as they grow, and flowers that have not been pollinated are much more likely to produce high-potency cannabis. This is the basis of all modern medical and recreational cannabis cultivation, so determining the sex of a plant is highly important. But is there a way to know if a seed is female before growing?
To identify the gender of the cannabis plant, you must examine what grows in between the nodes. The nodes are the part of the plant where the branches extend from the stalk of the plant. Male plants will have small pollen sacs for the purpose of spreading seeds while the female plant will have stigmas, which catch the pollen that male plants spread. It is best to identify the sex of the plant before the plant's reproduction cycle become active. Usually, it is possible to determine the sex of the plant by 4-6 weeks into plant growth.
Like most living creatures such as humans, animals, and other plants, the cannabis plant also has male and female genders and reproductive systems. Being able to distinguish between male and female marijuana plants is important for breeders and growers as the type of weed plays an important role in the value and quality of the final product that is being sold.
Therefore, it is crucial to continuously monitor your plants whilst stressors are distinguished and minimized so that your plant or crop can flourish. Plant stressors can include:

Only female marijuana plants can produce potent high THC buds. Thus, it is redundant to sell male marijuana plants as if will have minimal psychoactive effects and will not provide much of a high when consumed. Additionally, male plants can contaminate a crop of female plants by potentially fertilizing them. Once a female plant is fertilized, it will spend more of its energy on producing seeds rather than growing juicy THC nugs and flowers. Male plants can also crowd female plants, restricting the space for female plants to grow to their full yield potential. Therefore, growers will only plant crops of female seeds if they intend to cultivate marijuana into a sellable product.
Well, regular seeds have a 50/50 chance of growing into a female or male plant. So if you pull seeds from a nug and decide to plant them, there is no guarantee as to which gender the seeds will produce. This is why the production of feminized seeds has grown into a large market, allowing growers to know that the seeds they plant will grow into female plants.
