Feminized

Types of marijuana seeds that have been bred to produce only female cannabis plants, which produce buds. Feminized seeds are easier to grow than regular seeds and more common for first-time growers because they eliminate the process of having to sex out plants to remove males, which produce pollen and not buds. Because they have been heavily bred, feminized seeds are not suitable for commercial production, only homegrowing.

Regular vs. feminized marijuana seeds

Cannabis plants can be either male or female and only females produce buds. When a grower plants regular cannabis seeds they will be a mix of males and females, and the grower must raise the plants for a few weeks to determine their sex. Once identified, the males must be discarded because they will release pollen, causing the female plants to produce seeds.

Sexing out plants is a time-consuming process, involving additional space, resources, and labor, and you will always lose some seeds from the amount you started out with because some will turn out to be males.

Feminized seeds have been bred to only produce female marijuana plants, so every seed you plant will turn into a bud producer. Feminized seeds save time and space by eliminating the process of sexing out plants.

Feminized cannabis seeds are popular with first-time homegrowers because they require less work and are less complicated to grow, and you will always get a bud-producing plant. However, because feminized seeds have been bred more, they are not suitable for commercial production.

The truth is, having one season’s worth of a great harvest is a good thing – but you could make it great by setting your sights on the future.

You have so far achieved some very difficult stuff during your grow season. Maybe you had to overcome unforeseen obstacles. Do you want to make things easier next time around?

If your plants are currently maturing, start taking a closer look at them. Are there growths forming at the spot where stalk and leaf connect? Are some of your plants growing tall and skinny while others are remaining bushy and short?

These changes come from your plants reaching their sexually mature stage. As soon as this starts happening, you should be able to accurately decide which plants you will want to reproduce so you have a stash of pot for the entire year.

In this article, we will cover the basics of looking to future generations of growing seasons. The secret of success is your plants’ seeds, as well as the sexes of those seeds.

How to sex plants

The first step in making these crucial decisions is to determine which plants are male and which are female. You should start being able to do this once the season starts to change.

As soon as the length of daylight falls below eighteen hours per day, you will begin to see responses in the male plants. They will start to grow bud-like growths, which are actually greenish-white flowers in the shape of an egg. You won’t be able to mistake its gender once you shake these flowers since they will give off a cloud of pollen.

About two weeks later you will start to see distinct changes in the females as well. They will start to grow buds, which begin as a little cactus-like white growth at the ends of branches.

These buds will grow and grow until about a month has passed, at which point they will be significantly larger, sticky with resin, and odorous. Depending on the strain you are growing, this odor could smell similar to a skunk, or it could have a sweet, pleasant smell.

  • Time your harvest for Perfect Taste
  • Get THC levels for a Perfect High
  • Don’t waste any Precious Bud

Surprisingly, you can get a pretty good idea of which plants are male before they start reacting to the changes in daylight. In general, the male plants will be the tallest of your crop.

This is a simple evolutionary trait that was naturally selected over generations – by being taller and maturing faster, males are more likely to successfully drop their pollen onto the female plants as they are budding. Taller males will also have their pollen travel longer distances in the wind.

These male plants also die sooner than females. Luckily for you, you can cut off their flowers and smoke or eat them (after properly drying them, of course). You will be pleased with the resulting high since it will be almost as good as smoking the female buds of your harvest later.

What is pollination

To seed or not to seed? That is the eternal question of many marijuana growers – especially new ones.

When left to their own devices, male marijuana plants will fertilize the females, causing a new generation of seeds to be “born.” While this may appear harmless to the uneducated grower, it can significantly decrease your resulting harvest.

THC-rich buds

When female plants are fertilized, they will slow down their production of resin, which has a high amount of THC. An unfertilized flower contains the most THC you can find on any marijuana plant. Additionally, unfertilized females can remain in the flowering phase for a long time – between six and ten weeks – meaning a higher amount of these THC-rich buds.

All this means that you will need to decide how many (if any) female plants you would like to be fertilized, and how many you want only for your harvest.

Protecting your females from fertilization isn’t as easy as it sounds, but it is crucial to you getting a successful harvest in the end. The most effective way to do this is simply by uprooting your males and taking them away from your at-risk females.

Ideally, you already took the high male-female ratio into account when you initially planted. Marijuana plants generally are 70% male, so removing all your male plants will reduce the number of plants significantly.

Remember that the end result will be higher, so don’t fear this process. That being said, you better be completely sure a plant is male before removing it from your crop.

There could be nothing worse than to uproot a plant you thought was male, only to discover you just killed a huge female plant that could have significantly contributed to your end yield.

Plenty of growers who only want the marijuana for their personal use will simply allow the males to pollinate the females, and will remove the marijuana seeds from the harvest later.

How to make seeds

This process is best for indoor growers, and it involves fertilizing your plants. To begin with, you must identify which plants are male and which are female (see above).

You will, of course, need at least one male to fertilize your females, but usually one is enough. Choose the one male plant that you think has the best qualities, then remove all of the rest.

The next step is to isolate this male plant so that you can control its lighting separately from the females.

While the females still have continuous light, your male plant should have 12 hours of light and 12 hours of complete darkness. This lighting change will spur the male into flowering and therefore producing pollen.

You should take this pollen and save it since you’re going to need it later. Use a piece of paper to get the pollen from the flowers, and then drop the pollen into an envelope. Stick the envelope in a freezer to keep it fresh.

Meanwhile, keep your female plants in their vegetation phase for as long as possible. Once it is time for the flowering phase to begin, it’s time to use the pollen that has been stored in the freezer.

Decide carefully which females you will want to pollinate. It could be because she exhibits specific qualities you like, or maybe she comes from the same strain as the male plant and it happened to be a great strain, so you want to keep the strain completely pure.

Place the pollen in one cola of the female plant(s). Don’t pollinate flowers on that same plant, and don’t get the pollen in the flowers of the other plants, either.

The process of pollinating your plants must be done carefully. For best results, separate the whole female plant to avoid contaminating the other plants around it.

First, put the frozen pollen into a little bowl, and get a small watercolor paintbrush. Use this brush to glaze the pollen on the top of your female plant’s cola.

After four days or so, put the pollinated female plant under 12 hours of sunlight and 12 hours of uninterrupted darkness. This is the point when you no longer have to worry about cross-pollination since the pollen will be firmly stuck to the cola.

Keep a close eye on your pollinated female to make sure you harvest her seeds at a suitable time. Mature marijuana seeds will not be green, but rather will be some sort of brown color.

Once the seeds are mature enough, simply use your fingers to take them out. Label the container with the seeds and then refrigerate them all. As long as they remain cool and dry, they won’t lose their ability to germinate next season.

In the end, you will both have a nice, high-quality strain of seeds for your next growing period, and the rest of your unpollinated plants will produce wonderful weed. It is a great way to conserve financially while also increasing the quality of your future crops.

Feminizing seeds

At this point, you are probably thinking that the 70% male and 30% female average is pretty unfortunate. Most growers would agree with you. Unfortunately, you don’t have much control over your future plants’ genders when you use regular fertilization techniques.

This is why many take measures to make it more likely that they will get only (or mostly) female plants. One way to sway the odds in your favor is to feminize your marijuana seeds.

In general, you cannot tell the difference between male and female seeds. You also cannot change a seed’s gender. The idea behind feminizing your plants is to maximize the amount of females in your crop since female plants generally have a higher THC content than males, and, therefore, get priority.

Seed feminization utilizes a number of pollination methods to tip the scale in your favor. If you have some extra cash and aren’t feeling up to the challenge, you can also buy already feminized seeds from marijuana seed companies.

Buy feminized seeds

  • Every plant will produce flowers
  • No time wasted growing useless cannabis
  • Grow nothing but harvestable plants

That being said, buying feminized marijuana seeds online can often be hit or miss. Make sure the company you are buying from is reputable. This is the best seed shop online.

There are three types of feminization: silver thiosulfate, colloidal silver and rodelization. Each one, when properly carried out, should end up successfully giving you mostly female plant.

Silver Thiosulfate method

The new innovation if using STS (Silver Thiosulfate Solution) has somehow become commonplace – and it’s a great one because it is highly effective. It has allowed feminized seeds to be found everywhere, meaning that the average grower can buy feminized marijuana seeds.

Better yet, we can all rest assured that they are probably properly feminized, rather than the hit-or-miss feminized seeds market of days past.

So what is silver thiosulfate? It’s a half-and-half combination of sodium thiosulfate and silver nitrate. It simply causes a hormonal reaction of stress in the plant that triggers a change in gender.

So how do you actually create feminized marijuana seeds yourself? It involves a little bit more than drenching your plants in silver thiosulfate, unfortunately…

First you should decide which plants you’re going to use. They should all be female and from one strain, and nearly mature. Then just take one of them, separate it from the bunch, spray it with STS, let it dry, and finally replace it alongside its sister plants.

That plant will start looked very stressed out. It will turn brown and might worry you with how close to death it appears. Just five days later, however, it will begin its revival. In one month’s time, this plant will have finished its transition into being male.

At this point, you can simply shake the new male plant right over those same females, thus pollinating the female plants. Because the new male plant used to be female, the pollen it provides is actually female pollen. That means that, after just a couple of weeks, these pollinated female plants will create feminized seeds.

Although the process seems extremely simple, especially compared to other methods you may have heard of, this doesn’t mean you will have success on your first try. Luckily for you, breeders you might want to buy feminized seeds from always make sure each batch of seeds, along with the entire process, is successful.

They will, therefore, give you seeds that you can depend on. In fact, these days the highest end feminized seeds have a feminization rate of 99% or more, so this method is clearly a huge help to the marijuana industry.

Colloidal Silver method

For this method, you will need a very small amount of colloidal silver (pure silver) and distilled water. Put the former into the latter, then, using a spray bottle, apply the resulting mixture onto your female plants while they are flowering.

The plants will begin to form pollen sacs (which are normally seen on males). The pollen contains genetic material that is actually totally female – making it highly probable that the marijuana seeds the plant produces will be female.

That was the simple way of describing the process. Actually doing it is much more complex and involves many more details. In addition to the pure silver and distilled water, you need a 9-volt battery and connector, alligator clips, and soldering iron. Sound like too much trouble?

Assuming you have no problem with spending the time and money finding these “ingredients,” the next step in the process is to connect the battery and its connector.

Solder the alligator clips onto the red and black wires to form the best electrical current. Then connect these to the silver (probably coins) that you have.

How To Feminize Cannabis Seeds

If you’re a home grower who grows your cannabis from seed, you need those to be female seeds. In this article, we’ll explain why and also how to feminize cannabis seeds.

What Are Feminized Cannabis Seeds?

Cannabis plants are dioecious beasts, meaning they can be male or female. Although they look the same in the early part of their life cycle, there are marked differences between the two. Male cannabis plants produce male seeds and pollen sacs and have much lower potency than females. For that reason, most people involved in cannabis cultivation want to grow female cannabis plants. Females produce the much sought-after buds that cannabis is harvested for. They’re high in cannabinoids and terpenes and have all the trichomes and other components you need for medical or recreational cannabis use.

Why Make Feminized Cannabis Seeds?

As opposed to regular cannabis seeds, which produce female plants approximately half of the time, feminized seeds only produce females. That means every plant grown from feminized cannabis seeds will be a female, bud-bearing beauty.

Growing cannabis plants from feminized marijuana seeds takes the guesswork out of the gender game and guarantees your plants will be female.

Nowadays, almost all strains of cannabis are available in feminized seed form. This is because seed banks understand that most people buying seeds are more interested in producing cannabis flower. As such, the option to do so is available – although, if you’re a breeder and want to create a breeding programme, these seed banks also sell regular seeds of many popular strains.

How Do You Make Feminized Cannabis Seeds?

The general idea of the feminization process involves forcing female plants to produce pollen. That pollen is used to pollinate other female cannabis plants, resulting in feminized seeds.

There are two main ways to achieve this:

1. Chemically-induced pollen feminization

Of these two options, it’s far better to go chemically-induced. This method is used by professionals and has a significantly higher success rate. It also has a much lower frustration rate than the latter method. Rodelization creates feminized seeds through stress and, as such, can be a risky endeavour that increases the likelihood of hermaphrodite plants – and you don’t want hermie plants.

Marijuana plant and Cannabis seeds in a plate

So how do you feminize cannabis seeds with chemicals? There are several techniques and chemicals that you can use. The main ones are Colloidal silver, silver nitrate, silver thiosulphate, benzothiadiazole, and gibberellic acid. Of these options, colloidal silver is the easiest to get a hold of, but you can also make it yourself without too much difficulty.

Colloidal Silver

Colloidal silver is a solution comprising tiny – microscopic particles of silver suspended in distilled water. It’s sometimes used as a dietary supplement, meaning it’s reasonably easy to get a hold of. You can buy it on Amazon or from health shops. Disclaimer: Never ingest colloidal silver as a dietary supplement without speaking to your doctor beforehand.

Colloidal silver has other uses in horticulture, including as a means of fungal control. In creating feminized cannabis seeds, colloidal silver works by inhibiting the production of ethylene, a naturally occurring hydrocarbon gas. Ethylene is a hormone needed to produce female flowers, so we use colloidal silver to prevent ethylene from effectively making plants female. The result is that the male hormones dominate, producing male flowers. Afterwards, you collect the pollen from the plant and use it for pollinating other plants, producing feminized seeds. Colloidal silver guarantees you consistently get feminized seeds.

The Colloidal Silver Method: Step by Step

  • Begin by acquiring the right strength of colloidal silver, preferably 30ppm (ppm meaning parts per million). It’s available in other concentrations, and 30ppm seems to be the best for the job. Lower than 15ppm will result in male sacs with next to no viable pollen, so go with a higher concentration.
  • Select a plant that has the traits you wish to preserve. Put it into a small pot away from your grow room and give it a day or two to adapt, then put it on a 12/12 light cycle as soon as possible. If using a clone, you’re good, but if you’re growing a plant from seed, wait until the plant has sexed before treating it with colloidal silver. You need to make sure it’s female!
  • Once it begins the flowering stage, spray the plant, or plants, three times a day with colloidal silver, giving them a good soaking. Repeat this process over two weeks, and then leave them to grow as usual.
  • When sexing begins, your plant will develop sex organs – look for male pollen sacs on the bud sites rather than the calyxes and pistils seen in female plants. Look for little green balls appearing first at the top and then lower down the plant. Viable pollen appears within three to four weeks once the plant has been sexed. Collect the pollen and use it to pollinate other female plants. These plants will then yield feminized seeds.
  • Keep your treated plant isolated well away from females. If a pollen sac should burst, it will release millions of spores, and you don’t want them near your girls.

As soon as you’ve collected the pollen, discard the plants. Do not smoke them, and do not be tempted to try and rinse the colloidal silver off. Silver is a toxic metal, so never smoke the plant. Colloidal silver is absorbed into the plant’s foliage, and that plant is no longer fit for consumption. Toss it in the trash immediately.
