There is only one more problem. Cannabis plants can be both male and female in the right circumstances.

Cannabis Plants: Male, female and hermaphrodite

Determining the gender of your cannabis plants is the first step to a successful grow. Female plants are the only ones that produce bud cannabis. While it is fairly easy to spot the gender difference, cannabis does come with a curveball. Plants can also be hermaphrodites. And female plants can switch to this state during growing stress.

Cannabis plants are not gender neutral. There are female plants, from which the actual bud flower comes. Male plants produce the pollen. However, the cannabis plant is a bit odd in this respect. Female plants can turn hermaphrodite in certain circumstances – meaning they are both male and female. This happens in a situation where the plant is highly stressed, and fears for its ongoing survival. It becomes both genders as a last resort to self-pollinate and continue to spread seeds.

CANNABIS IS FROM BOTH MARS AND VENUS

Regular cannabis seeds are usually about 50% male and 50% female. The female plants produce bud cannabis. Male plants produce seed pods. They can also produce tiny amounts of THC via trichomes on the leaves. However, if you are not growing your cannabis as a science experiment don’t mess with male plants. It is a waste of time.

Obviously, particularly to the non-expert, all seeds look alike. That is why it is so important when growing cannabis, to buy seeds from a dealer or seed bank. While the plant is in the early stages of growing, it is also impossible to determine gender.

There is only one more problem. Cannabis plants can be both male and female in the right circumstances.

CANNABIS AND THE SEXES

Cannabis is actually much like other plants – with most having this ability. In essence, female plants have the ability to develop male characteristics. This usually occurs thanks to environmental stress. Plants will develop male characteristics at a certain point in the grow cycle in an effort to ensure seeds are produced before the stressor can kill the plant.

Such stress includes changes to hours of darkness during flowering, dramatic changes in temperature, drought and physical damage.

There are other environmental factors which can stress a plant into a sex conversion. This includes as a reaction to insects or disease. It can also occur with the use or overuse of certain kinds of pesticides and fungicides.

However, this tendency is also considered to be a sign of inferior plants. A good mother plant will not show signs of hermaphroditism even when subjected to this kind of stress. All cannabis can turn, but high-quality genetics will resist the urge the most.

As in the human world, hermaphrodite plants are considered a bit strange. In the cannabis one, they are dreaded. Breeders suggest removing such plants from a grow. The reason? They could create accidental pollination of the buds. If a pollen sac from one of these plants is allowed to come in contact with the buds of other plants, those buds will stop developing. They will instead, produce more flowers and seeds.

WHEN DO CANNABIS PLANTS SHOW GENDER?

The first sign of gender appears at the V shape on the plant where stalk meets stem. The plant will develop little green shoots or pre-flowers here. The plant may show pre-flowers when in the vegetative or growing stage. This is also more the case when the plant is a clone.

However, there are other ways to find out if any of your plants are hermaphrodites. The first is to check the kind of flowers they produce. The second comes at the end of the growing process. However, it is important to check before you grow the next time. If you find seeds in your harvested bud and you know you have no males, you have a hermaphrodite plant.

WHAT TO LOOK FOR

The first answer is an established breeder. The best way to start with an all-female crop is to buy the feminized seeds from an established source.

However, since this is a problem that will not disappear during the growing process, here are some guidelines for checking your grow.

Female plants take a bit longer than males to show signs of gender after flowering. The plants begin to develop a few wispy white hairs where the buds will soon grow. These flowers begin to form between the stalk and stem. Female pistils are always white (never green).

Male plants literally have grape-sized “balls” of pollen. The balls will show up about a week or two after the plant has entered the flowering stage. They also produce a growth that is a distinct yellow colour and look a bit like bananas.

If the male is allowed to continue growing, the pollen sacs will burst open. The pollen they spill can contaminate your other plants.

Hermaphrodite plants have both male and female flowers. That is also why it is so important to remove them.

ISN’T THIS LIKE ROCKET SCIENCE?

While it sounds complicated, it really isn’t. Growers who start with the right seeds and maintain a healthy grow environment do not have many problems. For this reason, however, it is important to watch your cannabis plants.

It is fairly easy to spot the difference in buds as the plants mature. That is also why it is generally a good idea to grow more than one plant – even the first time. Observation, practice and patience are the keys to a good and healthy grow. Feminized seeds produce femal plants 99% of time, and should one turn hemaphrodite, simply take care to remove it.

How to Pick Male Plants and Make Cannabis Seeds

Why Every Home Grower Should Make Seeds (At Least Once)

I encourage every single grower to make seeds for themselves. A lot of people have been asking how, so I put together these basic tips. Hopefully, it helps a lot of people and is fairly straightforward. This isn’t meant to make you a breeder or share all my techniques or secrets, this is to familiarize you with the process of creating seeds.

It’s easy to make your own cannabis seeds at home!

It’s a shame that many grow books tell you only to throw away your males. New growers may not know, but anyone who’s grown for even just a few years gets to the point where they wish they still had something they grew in the past, which is no longer available in seed or clone for whatever reason. The older you get the more it happens. Seed lines disappear entirely once they run out, and due to people not making their own. It’s good to be self-sufficient.

While it’s always fun to check out the hard work of your favorite breeders and their strains, it’s equally as important to pollinate a branch or two for yourself here and there and see what magic you can create or preserve. Please share this article if it helps or inspires you. Big agriculture is coming to the cannabis growing world and has the ability to change the plant forever once contamination happens, just like in the veggie world. We are losing genetic diversity fast as thousands of unique strains are lost. Please do your part if you are passionate!

How to Make Your Own Cannabis Seeds at Home

These are basic starting points for the home grower. I believe every person who grows cannabis needs to have this skill. Every strain goes away over time when people don’t make more seeds. Growers should know how to make their own seeds for preservation and sustainability. These skills can go a long way. The precursor to serious breeding is the basic technique of creating the seed.

1.) Grow Male Plants

Male plants can be grown in very basic conditions in an isolated space, then flowered for pollen. Males can be started flowering next to females with a close watch for the first week or two, but be careful and remove them before pollen sacks form, bursting open and pollinating everything.

Branches can be cut off and put into a cup of water on a windowsill or under a CFL bulb, even under veg light cycle once they are in bloom. Pollen can be collected within a week from these branches, saving lots of space. Males can also be cloned or flowered very small based on your needs.

Best, however, is flowering the males in their own tent or space. With a carbon filter and negative pressure, and careful practices, you can avo >(More on best male plant selection below)

2.) Collect Pollen

Pollen can be collected by tapping a budding branch gently over a piece of paper. Pollen will spread easily in the air, so make sure to turn off all fans. Visit males only after tending to female plants so you don’t accidentally bring any stray pollen on your clothes or hair!

3.) Pollinate Buds

Take out your female to be pollinated or shut off all circulation fans. Gently apply pollen to a labeled branch. The pollen must meet the white flowering hairs to create seeds. Week 3-5 is best to pollinate, and you can do a single bud or branch per plant and keep the rest seedless.

Every pollinated branch should be labeled properly, your memory will not last as you think it will. A proper branch label includes dates, strain names, breeder/sources, and has the female listed first and male listed second. An example label looks like this: 4/20/2015 – Star Pupil (Mass Medical Strains) x Prayer Tower Sativa 9 (Bodhi Seeds) and the label should be kept with the seeds when they are finished. As years go by, you will be thankful for the dates and breeder information, which can escape our memory on occasion.

4.) Deactivate Stray Pollen

Water generally deactivates pollen, wash clothes and shower if needed after handling. 3+ hours after pollination, the plant can be sprayed down with water to deactivate stray pollen and can be brought back into grow room and fans turned back on.

Avoid spreading pollen unintentionally. It can get everywhere!

5.) Collect Seeds

Seeds are done in 2-6 weeks and should be dried in the bud when the plant is harvested. Seeds should be sproutable within one month of drying.

What strains should I use?

Any strain with traits that you like, which speaks to you, or seems like a good cross, means your intuition is telling you something. Starting with stabilized or homogeneous lines is always a benefit. Certain genes such as Cookies, OG, and Diesels, are full of hermaphrodites and should be used with caution, only to be bred with if they are really your #1 passion. Follow your heart.

Crossing two unrelated strains for the first time is called an F1. Crossing a brother and sister F1 of the same strain creates an F2, and so on. Selections play a huge role in what the outcome will be. Making F2 seeds of an F1 you purchased, will not give you the same seeds. Rather, you will see new phenotypes resembling some of the parents and their parents, etc. With huge potential to find new special plants within.

Many combinations will work great, and some will not. If you fail, try again, selecting new parents. Each combination is unique. A and B might work great together, and C and D might work well together, there’s still a possibility that A and C combine to create junk. Every parental combo is unique!

If you see a unique trait that you like, make seeds!

Selection Techniques

Female Plants

Selecting a good female is easy, flower female plants from seed and again from clone to test stability. Smoke test is important. A potential mother plant should have all the high-quality traits that matter to you. Hermaphroditic plants are to be avoided.

Female plants to be pollinated should have all your ideal traits. Use only your best females.

Male Plants

Selecting a male, you have to use your senses a lot. The ones who grow best and smell best are a good starting point. Structure and root growth are important. Hollow stems may indicate high THC potential. Cut the top off a couple nodes down and find out. First showing or fastest flowering males are generally discarded. Very slow blooming late males are often times more recessive although not always. I like them. Males will start to drop pollen before they are “done” flowering enough to see their true traits. As a beginner, you can use the pollen at any stage, but those doing real selections are advised to always flower your males for weeks after the pollen starts.

For male selections, a strain you’ve grown before and enjoyed the females is a safe starting point.

Watch for resin production, look at how the flower clusters stack and produce. The male flowers form similarly to female flowers, large yield potential is often apparent in largely formed male clusters that can look almost like female buds from a distance. The more males you have to choose from, the more fun you will have!

Male plants can be a lot of fun to grow, too. Just like the females of the genetics they come from, they all have their own characteristics and unique traits. Once you get into “hunting males” you could get hooked! Some of my prized male selections from over the years are shown here. You’ll see resin production and traits of large floral clusters, as well as unique coloration!

For more advanced breeding selections, I recommend starting ideally a few hundred seeds. (For beginners, as many as you can is great, will help you find the best ones you can. Use your intuition!) Plants can be weeded out every few weeks selecting only the best contenders to flower out, and a lot can be achieved in a spare tent or closet this way, while still selecting through large populations! Clones of a prized breeding male may be kept in veg the same way females are, to be used again and again once their offspring are proven good! This is how a breeder can create the same batch of seeds for years and years, by using the exact same parents held in clone form.

Conclusion

These tips are just the beginning, and the purpose isn’t to teach you how to breed, but to teach you how to learn your own path and style of creating seeds and preserving our very special plant. The seeds you create will always be a very special grow for YOU.

Making your own seeds is more important than ever. We must do our part to preserve the natural genetic diversity of this healing plant as it has evolved for millions of years. Home growing is an important skill as commercial and medical cannabis is increasingly full of toxins and scary new technology. Please grow responsibly with love.
