As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
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.
Go easy on nutrients
Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
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.
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Well, that is where the feminizing technique comes into play: two methods of manipulating the cannabis plant to produce only females from seed, every-time. To be truthful, it isn’t every single time. But 99% of the time is a pretty good number, and could be considered entirely male risk-free.
Sinsemilla is an unnatural state for cannabis. Without human intervention, it would be rare to find an unpollinated female in the wild—unless it was sterile. When sinsemilla plants are left to go beyond their desirable maturation stage by a number of weeks, the plant, through whatever amazing processes evolution has bestowed, knows it has not been pollinated. As a last ditch effort at propagation, it will produce male pollen sacs in an effort to self-pollinate.
To begin with, select a plant that has the characteristics you want to preserved. Feminizing clones is the usual practice as the growth, flowering, and resin characteristics from the mother are already known. There is no need for any vegetation time once a clone is well-rooted. Simply pot the clone into a small pot, give it a day or two to recover, and begin a 12-12 light cycle right away. A pollen-producing plant only needs to be small as cannabis produces copious amounts of pollen.
Hint: Make two clones once a plant has been selected, one to be feminized and one to be left for pollination. This way, a separate breeding space is created and accidental seeding of other plants, or an accidental sneeze pollinating a whole grow cupboard, is avoided.
Plants bred using feminization are homozygous. This can have two effects that can’t be assessed until the seeds are grown. Homozygosity will increase the dominant or recessive traits of the parent in the progeny, so features you don’t want and do want can be amplified. Genetics is a weird, weird thing.
When we talk about cannabis it’s easy to get caught up in the beautiful females that produce those cannabinoid-rich buds we all love and treasure. In fact, we have become so focused on the female cannabis plants that it’s almost considered a bad omen if a plant happens to turn out male.
This pollen plays an important role in breeding as it allows expert breeders to mix and match the genetics from different plant varieties to create their own cannabis seeds of their own strains.
WHAT IS CANNABIS POLLEN?
If your cannabis seeds don’t meet this description, let your plant develop a little longer. Some cannabis plants can develop mature seeds really late into their flowering cycle. If that’s the case, make sure you keep your plant alive with plenty of light and nutrients.
Remember, only the bud sites that come into contact with pollen will develop cannabis seeds. You can choose to apply pollen to parts or all of your female plant. You’ll also want to make sure you directly touch the pistils/hairs on a bud site to ensure the area is well pollinated.
As we mentioned earlier, cannabis pollen is typically used by breeders and expert growers to create new strains or seeds. They do this by harvesting pollen from their male plants and then applying it to female plants that are about 2-3 weeks into their flowering cycle.
