Understanding Male and Female Weed Seeds: Key Differences Explained

by Sep 24, 2025Cannabis Education, Garden Tips, seed collecting, seed storage

Ever put weeks into a plant just to find out it won’t give you any buds? It’s a gut punch. It all comes down to knowing about male and female weed seeds. Get this right, and you’re on your way.

Your Crash Course on Male and Female Weed Seeds

Figuring out the difference between male and female weed seeds is probably the first real lesson for anyone getting into growing cannabis.

It’s pretty straightforward, really. You want the female plants. They’re the ones that grow the dense, sticky buds everyone is after. The male plants have a different job. They make pollen. If that pollen gets on your females, you get a crop full of seeds, not the quality buds you were hoping for.

 

Key Takeaways

  • Female plants are what you’re after for a harvest. They are the ones that produce buds.

  • Male plants are for breeding. They make pollen, which creates more seeds. Most growers get rid of them on sight.

  • Feminized seeds are a way to make sure you only grow female cannabis plants. A huge time and space saver.

  • Regular seeds will give you both males and females. They’re for people who want to breed or don’t mind the extra work of weeding out the males.

So, Why are Female Plants That Important?

A study in Frontiers in Plant Science from 2020 points out that cannabis is a dioecious plant. That’s a science-y way of saying it produces separate male and female plants.

The females grow the flowers with all the good stuff. The males grow little pollen sacs. If those sacs burst open near your females, it messes things up. The female plant’s whole mission changes. It stops putting energy into making big, frosty buds and starts making cannabis seeds instead. For most growers, that’s a failed crop.

How to Tell the ‘Boys’ from the ‘Girls’

You save yourself a world of pain by spotting the males early. The trick is to look for the ‘pre-flowers’. These are tiny signs of sex that pop up where the branches meet the main stalk.

A male plant shows little green balls. They look like tiny bunches of grapes. Those are the pollen sacs.

A female plant shows a small teardrop-shaped pod with a couple of white hairs, called pistils, poking out of the top.

You’ll see these appear a few weeks into the vegetative stage. Get the males out before they open up and release that pollen.

Choosing Your Seeds: The Big Decision

Alright, so you know you need female plants. The next question is, how do you make sure you get them?

Getting poor-quality seeds is a waste of money and months of your time. You need a source that provides solid genetics. Below are a few reasons why thousands of Aussie growers trust a local, family-run operation like Sacred Seeds Australia.

1. Fast Local Shipping – No Customs Delays or Risks

There’s nothing worse than waiting weeks for an order from overseas, just to have it nabbed by customs. Because Sacred Seeds Australia is right here in the country, you get your order fast. We ship with Australia Post, and orders usually arrive in a few business days.

Everything is sent in discreet, compostable packaging, too.

2. Great Selection of Premium Strains (High THC, CBD, Autoflowers)

We have over 50 different strains from top breeders. You can get famous high-THC strains or find something with high CBD for medicinal purposes. We’ve got feminized photoperiods, and we’ve got autoflowering seeds, which are great for beginners because they are almost always feminized and flower automatically. You find the right seeds for your plans, whatever that is.

3. Proven Genetics and High Success Rates

The genetics inside that little seed shell determine everything. Bad genetics lead to weak plants or plants that turn hermaphrodite under stress.

We focus on premium, stable genetics. One Aussie grower on a forum said our seeds produced “almost twin plants with every strain, so if that ain’t stable I don’t know what is.”
That stability is what you pay for. It means your female plants will grow the way they’re supposed to.

4. Rave Customer Reviews and Trustworthiness

Talk is cheap. Results matter. Our website has over 1,800 verified reviews from real customers. People talk about the fast delivery and high germination rates.

One Reddit user put it plainly: “the business is definitely legit, safe payment with competitive pricing and quick shipping from within Australia.”

We’re an Aussie family that values our reputation.

 

Benefits of Getting Quality Seeds

Good seeds make everything easier.

  • Better Yields and Potency: Good genetics mean your plants have the blueprint to grow big and strong. With our feminized seeds, you’re not wasting space on non-budding males.

  • Major Cost Savings: It saves you a lot of money in the long run. One single seed that costs maybe $15 can produce hundreds of dollars’ worth of flowers.

  • Fewer Legal Headaches: For those in the ACT or with a licence, using a local supplier like us avoids the legal troubles of importing. We ship discreetly from within Australia, which is a much safer bet.

Few Things To Be Careful About

Today’s high-THC strains are very strong. Research from the British Journal of Psychiatry found links between heavy use of strong cannabis and psychosis, especially in younger people. So go slow and know your limits.

And while it feels like a harmless plant, about 1 in 10 regular users might develop a dependence, according to Australian health data. Be mindful of your use.

Finally, know your local laws. Outside of the ACT, germinating marijuana seeds is illegal. Seeds are sold as souvenirs for adults. Always follow the law in your state.

 

FAQs

 

What are hermaphrodite plants?

A hermaphrodite or “hermie” is a single cannabis plant that develops both male pollen sacs and female flowers. It often happens due to stress and is bad because the plant can pollinate itself and your other female plants, filling your buds with seeds.

If I find a male, how quickly do I need to remove it?

You should remove it immediately. The pollen sacs can open very quickly once they are mature. Check your plants daily once they start showing pre-flowers.

What’s the main benefit of autoflowering strains again?

Their biggest advantage is speed and simplicity. They switch to the flowering stage automatically based on age, not a light schedule. This, combined with them being feminized, makes them perfect for new growers.

How long do baby cannabis plants take to show sex?

Baby cannabis plants usually show pre-flowers around week four to six of the vegetative stage. Experienced growers check carefully to determine sex before pollen sacs form.

What’s the difference between feminised seeds and female seeds?

Female seeds is a loose term some people use, but feminised seeds are specifically bred to produce only female cannabis plants. They’re the safest choice for people who want only females.

Do male or female plants grow faster?

Male or female plants grow at similar rates early on. Male cannabis plants often show pre-flowers earlier, which helps growers spot them before they produce pollen.

Are there guaranteed female plants?

Using feminised cannabis seeds is the closest you’ll get to guaranteed female plants. Most growers prefer them to regular marijuana seeds because they save time and space.

What’s the difference between feminized plants and feminised strains?

Feminized plants are the actual marijuana plants grown from feminised seeds. Feminised strains are the specific cannabis strain genetics bred to reliably produce female plants.
