In reality, the frequency of feminized seeds becoming “hermies” is very low, since professional breeders use chemical stimulation to encourage plants with strong genetics to adopt intersex characteristics. This is all performed to successfully carry out fertilization between the two females.
In the case, that you’ve already purchased a bag and are unsure if it contains “hermies,” here are physical signs of to look for.
HOW TO BREED FEMINIZED CANNABIS SEEDS
Most small scale cultivators desire an exclusively female crop, producing seedless buds, that can be smoked, extracted and vaporized for their consumption. For this reason feminized cannabis seeds have become the standard for many home growers across the globe.
Pollen sacs are easier to see with the naked eye, but the stamen “bananas” are smaller and thinner. They also appear to have a lime green color at times, camouflaging them into the rest of the plant. While pollen sacs and stamens can both be physically removed, it’s likely they’ve already been pollinating for some time, making it too late to save your yield for that particular plant.
Chemical additives are another often used method of “forcing” female plants to produce their own pollen. By spraying female plants with solutions, such as colloidal silver, they will begin to pollinate, culminating in the production of seeds.
The bagseed gamble… When you find seeds in your buds, that usually means that the buds were pollinated by accident. Seeds that were accidentally created are suspect. It could be that a stray male plant caused them, which means there were no hermies and you will get about half male and half female plants. But accidental seeds could also be the result of herming by an indiscriminate grower, and that means you have feminized seeds, sort of. Some of them may produce pollen on you just like their parents. Growing with bagseed is a big gamble… you never know what you’re going to get.
This technique works on nearly any female plant, including plants that would never hermie naturally. So it can be used to take two plants with great genetics to produce female seeds. But the same process will also work incredibly well on plants that do hermie easily all on their own. That means it’s up to the breeder to test and make sure that they have a solid plant with unbeatable genetics before using the feminization technique.
The pollen that results from chemical stimulation is used to pollinate another female plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation, then you have created feminized seeds that won’t ever make pollen in your grow room.
high stress – high temperatures, light leaks, inconsistent light schedules, as well as other types of major stress can cause a healthy plant to hermie, though some plants/strains are more susceptible than others
Unfortunately, hermies can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s affected. A male plant makes itself known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs. A few yellow hermie bananas hidden in the buds can also produce pollen. Any type of male flower part that grows in your garden can add seeds to your buds, and hermies are some of the worst offenders.
bad genetics – the plant comes from a line of plants that naturally create hermies for no reason, even in good growing conditions
You don’t have to throw away half your plants after nurturing them for weeks
