Negative stressors can combine with small interruptions of the light cycle to cause hermaphroditism, especially with less-stable, clone-only hybridized strains. When the night cycle is abnormally interrupted, it sends a mixed hormonal signal to the plant. This can cause a full female plant to throw some male flowers. Male flowers are easy to identify, especially when side by side with female flowers. Male flowers look like small bunches of bananas, which will take a week or two to swell before they burst and release their pollen.
In either case, once hermaphroditism has compromised the safety and purity of your sensimilla, the plant should not be propagated further. Remember, once a hermy, always a hermy. The plant pictured here is in the tenth and what should have been the final week of ripening, but a timer failed and one light stayed on continuously for almost two weeks, causing this vegetative regrowth. Because the light was continuous, the plant made no pollen. This method of re-vegging can be used to save a flowering plant you have no copies of, but be careful, as this may cause some strains to hermaphrodite.
Finding a hermaphrodite in your growroom can happen at any stage of the flowering cycle and is indicated by the presence of male flowers growing on the same plant as female flowers. As with all species in nature this can occur in varying degrees. A plant can become slightly or majorly hermaphroditic. In cases where singular male flowers are found between the branch and stalk nodes, you should be diligently removing them as they grow. You must re-inspect the plant top to bottom every few days to be sure pollination and seeding doesn’t occur. If you find male flowers (anthers) actually growing from within the female flowers (buds) the situation is a little more dire. You can still remove all the male anatomy as it appears, but it will be harder to find and much more prevalent. This is a horrible discovery that leads to a tough decision: Should you let the plant live and risk the whole crop being ruined by seeds?
Light poisoning refers to the flowering night cycle of a plant being unnaturally interrupted with light. The best way to prevent this is to close yourself inside your darkened room during the daylight, and then after allowing a few minutes for your eyes to adjust to the dark, check for any light leaks from covered windows, door jams, etc. Also cover all timer and appliance lights with tape.
Light poisoning is the most common cause for a normal plant to hermaphrodite.
Cannabis plants are monecious. This means they have the ability to be either male or female. Or in the case of hermaphroditism, they can be both. The reason to make sure there are no males or hermaphrodites in your garden is because male flowers make pollen. When pollen touches the white hairs on a flower, it makes a seed, and seeded weed gives you headaches. Even though there are reasons in nature hermaphroditism could be important, such as continuing the species in case there is no male present, hermaphroditism is generally a bad thing when talking about cannabis plants.
Female plants are basically what everyone is after when growing cannabis, as these are the ones that make buds, which is the part of the plant that contains the most THC. With just one male plant and a miniscule amount of pollen, your plants might end up filling their flowers with seeds. If you have male and female plants in the same growing area, the buds grown there will only produce seeds so you won’t be able to smoke any of it. You can tell females apart due to the fact that their flowers don’t fully close, they’re actually quite open and they produce little hairs called pistils. They’re incredibly easy to recognize, as the first thing they produce are their pistils, which male plants do not have at all.
Male plants essentially produce pollen which is needed for cannabis plants to naturally reproduce; seeds occur when there are male plants in the mix. If you want to make your own seeds you will need a male plant However, if you’re growing regular plants and want to harvest flowers, we recommend getting rid of any males as soon as possible. You won’t be able to tell them apart until they begin to flower, which is when plants begin to show their sex. Male weed plants grow “balls” that open up to let their pollen out, ending up looking like a small bunch of flowers. You’ll need to get rid of them way before this happens. If they manage to release their pollen it’ll be too late. They can take up to three weeks to burst. If you’re still not sure how to tell them apart, male flowers do not have any pistils on them at all.
One of the biggest evolutions has been the appearance of feminized plants; after years and years of work, cannabis plants can be created to have a 99% chance to be female. You need to know how to tell male from female plants when growing regular seeds, as you’ll only get actual psychoactive weed from the female flowers. Male plants pollinate female plants, which fills their flowers up with seeds so if you’re looking to make the most of your plants you’ll want to keep them away from each other. Hopefully we can help you to tell the difference between male and female weed plants by the end of this article; it’s not that hard, but if it’s not explained correctly it can be a bit confusing.
Cannabis plants have evolved enormously over the past couple of decades, mainly thanks to human kind. We’ve spent years combining different species from all over the planet. Every strain has its own specific characteristics, such as structure, type of buds, flavor and effects. When you combine male and female weed plants that are different strains, the new creation takes on characteristics from both, allowing us to create totally new plants.
Hermaphrodites are a type of plant that contains both male and female flowers, so they will produce buds but they will also pollinate those buds and the rest of your plants. Plants may naturally become hermaphrodites or be turned into one due to stress. Both female and male plants can turn. Thai strains are more genetically inclined to become hermaphrodites, although any strain can turn when stressed enough. There are many factors that can stress out your plants and end up turning them, such as extra light when they’re supposed to be in the night cycle, too much or not enough water, certain insects or pathogens, watering with cold water, or even a badly done transplant. Hermaphrodites aren’t the best type of plants to keep around, as they can produce buds but it’s definitely a risk because they might pollinate the rest of your plants. We recommend getting rid of them; it’s not worth it just for a little bit more weed.
It may seem confusing, but it really isn’t hard to tell male and female weed plants apart; they are quite different. Planting regular seeds has its benefits, as well as feminized has its inconveniences; you can get much larger yields with feminized plants as you’re guaranteed no male plants. Although, keep in mind that feminized seeds haven’t been through a 100% natural process to become female, which may affect the quality of your weed. This is why many cannabis connoisseurs haven’t made the leap from regular to feminized yet; they prefer to harvest slightly less yield that’s more potent and delicious.
