Beside a stipule which is itself a green hair like growth on the stem, you will see the preflowers. You are hoping to see a wispy white hair at the node. If you see any kind of ball and no hair you’ve got a male. Until you can see a white hair emerging from a few nodes you really can’t be sure you’ve got a female cannabis plant.
Instead of focusing on producing more resinous flowers the female cannabis plant begins to develop seeds. The cannabis will be less potent, and seeds will form in the bracts that contain the ovule. Sensimilla, which means seedless, is entirely dependent on female cannabis plants not getting pollinated.
Autoflowering cannabis plants tend to suddenly erupt with flowers quicker than you would expect. Somewhere between day 15-35 post-germination, your feminized autoflowering cannabis seeds will have multiple white pistils bursting forth from the first flowers. A week or so later and buds are beginning to swell up with calyx’s and sparkling with resin. Pistils will rapidly change colour from white to orange/red in days rather than weeks.
Pistils tend to poke out from nodes pretty randomly on young cannabis plants. Carefully inspect your cannabis plants and you will spot preflowers sooner or later during vegetative growth. Sometimes they are obvious, close to the top of the plants and easy to spot. But this is not guaranteed so really examine the plants carefully.
A pistil is a female cannabis plant sex organ. To the ordinary decent home grower, a pistil is a hair that protrudes from a calyx on a female flower. They are also known as stigmas. When a pistillate hair comes into contact with pollen from a male cannabis plant, it is then pollinated.
Typically male cannabis plants will develop preflowers sooner than their female counterparts in the cannabis garden. 3-6 weeks post germination you should be able to confirm that your feminized photoperiod seeds really are all females even if they are still in vegetative growth. Likewise, if you have regular seeds, you should be able to identify the male plants for removal before flowering.
Do you want Sensimilla? Then you need to make sure none of your female plant’s pistils get pollinated. This means you must continue to monitor your plants throughout flowering. Disturbances in the dark cycle are perhaps the greatest stress factor that contributes to hermies.
You may have to wait as long as 8 weeks of vegetative growth with some strains to confirm female cannabis plants. However, after 4-6 weeks most growers can at least weed out the males. And keep an eye on one or two uncertain plants in early bloom if need be.
Female plants and intersex plants will display pistils. Unfortunately, intersex plants will also produce pollen and are as great a threat to your females as a rogue male cannabis plant. Moreover, stress can cause any cannabis plant to develop intersex traits. Some varieties of industrial hemp are bred specifically for their hermaphrodite characteristics.
Whether you grow your weed from autoflowering, feminized or regular seeds, it pays to know about pistils. Here’s what every cannabis grower needs to know.
When looking in awe at fresh “bud,” you can’t help but notice its magnificent complexity: sugary crystals, fiery hairs, rotund nugs, immersed in little leaves. But, have you ever stopped and wondered what purpose do each of these components of cannabis’s anatomy serve?
Let’s start with the “birds and the bees”:
Identifying and selecting the right male plants will help ensure they’ll be passing on good genes to their kids. They are, after all, providing half of the DNA towards the offspring. With a good “baby daddy,” the offspring will most likely inherit many of the most important traits, including overall health, resistance to mold and pests, and growth rate. While their influence on potency and flavor may be less pronounced, however, savvy breeders can instinctively identify male plants that will make ideal breeding partners.
Moreover, males can be useful when breeding auto-flowering strains, where they exert significant influence on their offspring’s growth patterns while allowing the flowers to preserve the potency and flavor of “mamma bud.” And, they play a vital evolutionary role in their species.
Beyond the basic sex characteristics of male and females, much like their cousins in the plant kingdom, the cannabis plant is made up of several structures. The stems of cannabis skinny boasting their iconic fan leaves that extend from areas called nodes. But, where cannabis really assumes its remarkable properties is when she begins to flower.
First, the good males make great fathers. High quality male plants play a pivotal role in any cannabis breeding program. After all, the female plants would get pretty lonely! — they need pollen from a male.
Dense on active constituents including cannabinoids and terpenoids, trichomes pack a lot of punch. They produce the the medicinally rich reason used in a variety of concentrates and extractions including BHO (Butane Hash Oil), kief, hash, and their modern interpretations popular for dabbing: wax, shatter, and glass.
Trichomes may be tiny, but given how prominently they feature on the cannabis flower, it’s difficult to underscore their importance. These bulbous globes that are beautifully translucent, microscopic resin glands that coat the flowers with their crystally-like magnificence. Trichomes are also rich in cannabinoids and ooze aromatic oils called terpenes, which is what is responsible for cannabis’s euphoric and therapeutic effects.
But, to say male plants are useless, is factually incorrect.
When looking in awe at fresh "bud," you can't help but notice its complexity: sugary crystals, fiery hairs, rotund nugs, immersed in little leaves.
