How To Make Your Own Marijuana Seeds


how to make your own marijuana seeds

Up to this point, your growing project has been solely focused on fulfilling practical necessities that will ensure the survival of your plants, Using patience, skill, and a little bit of luck, you should have spent the last six to eight weeks watching tiny seeds grow from fragile-looking seedlings into leafy thriving marijuana plants. Now that your crop is thriving, it’s time to turn your attention to the future. Maintaining your garden, deciding when to harvest, and even planning for next year’s crop are all issues that are directly affected by each individual plant’s gender.

As your plant matures (and you get one step closer to that first satisfying puff on the most delicious, home-grown, and pampered pot you’ve ever smoked) you will start to notice changes in foliage production and developing appendages. Small growths will appear at the juncture where leaf stems connect to plant stalks. Certain plants will grow taller and thinner while others will remain short but bushy. These changes are a direct result of the plants reaching a new level of growth in which they are sexually mature. Once plants begin to show signs of their gender, you can better identify which plants will be more potent and which plants you wish to reproduce to keep you smoking throughout the year.

Sexing Your Plant

Like most plants, cannabis is photosensitive, growing in different ways in response to lengthening, then shortening summer days. When changing seasons cause daylight hours to drop below eighteen hours, marijuana plants are triggered to enter their “flowering” (also known as (“fruiting”) phase. Male plants react first and fastest, producing “false” buds with tiny green-white egg-shaped flowers that visibly emit a cloud of pollen when shaken.

Females trail males by about two weeks, finally showing their gender by developing a growth at the ends of the top and each branch that resembles a tiny whitish-haired cactus. In another month those infant buds will have taken on considerable mass, their outsides will be sticky with resin, and they will give off strong odors that may range (presuming your seeds were culled from “commercial” pot) from very skunk-like to a sweet, even pleasant bruised-fruit odor.

Before waning daylight forces cannabis plants to openly reveal their gender, a good rule of thumb is to anticipate that your tallest plants are likely to be males. Beginning pot farmers usually find that revelation to be depressing, but male plants have evolved to grow faster and taller and to mature before females. By towering over females, male flowers can drop pollen down onto budding females, and the tiny granules will travel farther on a breeze.

Males also die more quickly, sometimes before the first frost, and until they do, the flowers they produce can be snipped off, dried, and smoked (or eaten) to produce a high that is nearly as good as the one gotten from smoking bud. A male’s flowering stage can be prolonged by trimming several inches from the tops and ends of branches, leaving some flower-bearing stalks below to regrow into more “male buds” that can be harvested and smoked.

Seeds or No Seeds?

As the existence of genders implies, marijuana plants in the wild reproduce when male pollen fertilizes female flowers and the next generation of seeds are produced. As a grower you have to decide if you want to allow some of your plants to develop seeds or if you want to keep your crop unfertilized so that your plants remain unaffected by the chemical changes caused by reproduction. Seeds can be a tricky issue for home growers. It’s a definite bonus to have your own stash of seeds for planting next year’s crop, but reproducing can have adverse effects on several characteristics of the female plant.

As soon as a female plant is fertilized, the production of resin (which contains significant concentrations of THC compound) begins to slow down as the plant concentrates on producing seeds. In contrast, the “bud” of an unfertilized female flower is the most potent part of any marijuana plant. Even more important, a female plant can stay in the “flowering” stage for six to ten weeks as long as no fertilization takes place. This unfertilized state results in the growth of numerous buds all over a healthy female plant. Many urban legends surround the topic of seedless “ganje,” Seedless buds are easier to deal with because there’s no need to painstakingly remove foul-tasting seeds that might be inadvertently rolled into a joint or stuffed into a bowl. Pot growers who bootleg their crops like seeds because they add weight. After that, as the weed makes its way through the marketing process, the value-subtracted effect of seeds on profit is passed on until only the terminal buyer, the user, pays for pot seeds he can’t smoke. if you prefer the convenience of ganjano seeds, just peel a bud from its stem and stuff it into a paper or a bowl-then you’ll want to uproot male plants as soon as they begin to grow flower buds at the tops and at the ends of their branches. Ideally, this will be done before the first pollen-bearing flowers appear.

Males are always the first to reveal their gender, beginning with tiny flower buds at the ends of their branches and tops that might be mistaken for the female buds that are the real prime smoke in terms of potency, fragrance, and taste. It takes a trained eye to confidently rip out large, healthy male plants at the first sign of a bud; no horror could be greater than to kill a 4-foot female that would potentially produce 2 ounces of lovely buds. And because male plants begin emitting pollen granules as soon as they bud, even before they actually flower, the most earnest attempt at producing pure, seedless buds ends up with a few seeds. Fortunately, there are seeds in most “street” marijuana, because to prove a point, every plant shown on these pages was sprouted from seeds culled from a half ounce of pot I bought from a local seller. There are nine females out of eighteen adults in this crop, which is below the 70 percent male average. Like most personal-use growers, I let the males pollinate the buds, and when this harvest comes in there will be more seeds than I’ll want to plant.

  12. bettyBright on

    U should buy a grow lamp off of amazon good prices and u will never havr to worry again

  13. bettybright on

    U cN smoke it all so yes to ur question smoke away!!! Make sure to get the seeds out first than u will have more to plant later lol

  14. hey guys i am from pakistan and here cannabis grows on side walks and there is no one to cut it down. so, i was wondering if i could you know make some weed off the wild stuff now i dont know if they are all male or female but i think the shorter ones are female and the taller ones are male so i am new to this i know nothing and i dont know if the males or the females make weed and seeds and if it is possible to make some weed please guide me.

  15. I have a very small plant that is bearing seeds and its only 3 inches tall. I planted the seed to start growing this plant in November. I only give it natural sunlight. Is this plant worth the time to try to keep growing? It hadn’t grown any more in over a month.

  16. Where can i get some seeds? I know they must be very expensive…is there anyway i can get them for a cheaper price? And not online neither. Somewhere near Boston…?

  17. I got rid of my males before the flowers opened. I’m starting to see seeds in my females. Does anyone think I’ll have many. So does this prolong the following process? To avoid this in the future I’m ordering feminized seeds.

  18. Cannabis Country on

    You are correct to a point. A few seeds wont hurt the potency of the bud, however a plant that is fully seeded will not be as potent as one that isn’t fully seeded or only has a few seeds. Let me explain why.

    When a plant is fertilized with pollen it diverts its energy from producing buds to producing seeds, therefor you get smaller, less potent buds filled with viable seeds. The whole goal of a female cannabis plant is to get fertilized. When it is not fertilized it focus’s on growing its buds and lots of trichomes so the trichomes can catch pollen that in nature could be flying by the plant in the air. The trichomes is what “grabs” the pollen. So once it is fertilized it doesn’t really need to produce bigger buds and more trichomes because its job is done, it got fertilized. Once fertilized all energy goes into the seeds. If you know botany you will totally understand this process.

    You are correct about the less smokeable buds and lower yield, but the quality is NOT the same. Like I said though if the plant only has a few seeds there really wont be a big difference. Many times those few seeds were actually created by the female plant itself. How is that possible you ask? The female plant will hermie mostly due to stress. Its a survival mechanism. I could go into the science of that, which would lead to feminized seeds but I think I got the point across.

    My source: Basic Botany, Years of experience, Hundreds if not thousands of books read. I am known as a experienced grower and I am the owner of a on the rise cannabis website.

  19. I was shocked that anyone would respond anyway, but thanks so much for being a patient teacher. Must make you very popular, calling those seeking knowledge obtuse. You should get a medal or something.

  20. Yeah, So what. You can get stoned off male flowers BUT males produce very small usable weight. Its not worth the time and effort o keep them in a grow unless you are breeding for seeds. Like I implied, cannabis users use the term “buds” differently than a grower would. the flower clusters on both plants could be called buds in the context of botanical/growers terms but not exactly the same as general cannabis users use the term. We are getting to the point where you are just being intentionally obtuse, You will very easily be able to tell the difference between the flowers of different genders and in over 10 years as a smoker I never had anyone ever try to sell male flowers. It just doesn’t happen. Read some books, I’m done responding to you.

  21. “Males also die more quickly, sometimes before the first frost, and until they do, the flowers they produce can be snipped off, dried, and smoked (or eaten) to produce a high that is nearly as good as the one gotten from smoking bud. A male’s flowering stage can be prolonged by trimming several inches from the tops and ends of branches, leaving some flower-bearing stalks below to regrow into more “male buds” that can be harvested and smoked.”

  22. You will never mistake dried male flowers for female buds. There are no “male buds” as most cannabis users use the term “bud”. The closest thing would be a hermaphrodite where female buds has some some male flowers and its usually mostly bud just a bit less compact bud.

  23. I am not a grower, but I would like to know how I can tell if I was being sold a male bud instead of the more potent female bud. If I am unhappy about the strength of my medicine, how can I tell what the problem is? Or if the problem is even fixable? Since I have purchased quality, I know it can be done…

  24. Male flowers look quite different from female buds. Its easy to tell. Plus male flowers throw off huge amounts of pollen when they mature which is quite faster than female buds. Just do a google search for male cannabis flowers and you’ll see. Only during very early flower development is it difficult for some novice growers to tell the difference.

  25. Since I have nothing better to do right now, I will respond to your oddly suspicious query:

    “Really?” Yes, really.

    “I see you post here often with many opinions and you cannot tell the difference between male and female flowers?” Yes, that’s correct. If you’ve seen my posts before, then you know I don’t grow. So I don’t understand why you would think that every MMJ patient knows the difference between male and female plants.

    “Do you even use MMJ?” Yes, card-carrying member.

    If you have a problem with one of my “many opinions,” please do speak up. I look forward to answering any follow-up questions from… whoever you are.

  26. I can't believe it on

    Really? I see you post here often with many opinions and you cannot tell the difference between make and female flowers? Do you even use MMJ?

  27. I am trying to figure out what I’m looking for in the end product, trying to visualize what the absolute best bud looks like and why it looks that way. I’ve tried looking for trichomes, but you can’t use this all by itself either. (For example, I found a large amount of trichomes on a high-CBD bud, but of course the THC strength wasn’t there.) I keep thinking that I need to be looking for bud with high resin, and by what I understand in this article, that would be a good sign. But what happens to resin in the drying and curing process? This would obviously affect the look of the resin, but what about the consistency of the resin?

  28. The presence of seeds alone does not affect potency. The only drawback of seeded buds for the consumer is that they’re a PITA to remove. For the grower, it means less smokable buds (lower yield), but the quality will be the same.

  29. But the male bud also doesn’t have any seeds, so how would I be able to tell the difference? Isn’t the male bud less potent than either of these (the unfertilized female flower and the seeded female flower)?

  30. Robert Eckerson on

    In contrast, the “bud” of an unfertilized female flower is the most potent part of any marijuana plant.

  31. Great article, thanks. So a purchaser of marijuana can be assured that they are getting the female buds, as long as it has seeds? And the more seeds the bud has, the less potent it can be? Have I got this right?

  32. Good description of the sexuality of cannabis…One caution, however…when crossing brothers and sisters (see from same bag/plant) you run the risk of getting double recessive genes with sometimes very bad results, especially when dealing with hybrids. Bad genes can result in NO resin production (revert to rudallis or even hemp), hermaphroditic plants, spindly plants, etc., so be very selective in your breeding program…a female from one source and a male from another source would be preferable. then selectively seed individual buds by hand, using a paint brush to transfer the pollen to the flowers and not let the entire plant go to seed…..
