If you have searched for "non-feminized seeds" and landed here, the short answer is this: non-feminized seeds are regular seeds. The two terms describe exactly the same thing — cannabis seeds that have not been through the feminization process and therefore produce both male and female plants. This guide explains what that means, why some growers specifically look for non-feminized seeds, and how they compare to feminized varieties.
For a full overview of all seed types including feminized and autoflowering, see our complete guide to cannabis seed types.
What "Non-Feminized" Means
The term explained — and why it is just another name for regular seeds.
A non-feminized seed is a seed that has not been selectively bred to produce female plants only. In cannabis, this means the seed follows the natural genetic pattern: roughly half of the plants that germinate from non-feminized seeds will be female, and roughly half will be male.
The term "non-feminized" is used most often by people searching for an alternative to feminized seeds — either because they want male plants for breeding, or because they are looking for seeds in a more natural, unmodified form. In seed bank catalogues, these seeds are almost always listed as "regular seeds" rather than "non-feminized," but the product is identical.
Non-feminized seeds are photoperiod plants, just like feminized seeds — they require a change in light schedule to trigger flowering. The only practical difference between a non-feminized (regular) seed and a feminized seed from the same strain is the likelihood of male plants appearing in the batch.
Why Choose Non-Feminized Seeds?
There are specific situations where non-feminized seeds are the right — or only — choice.
- Breeding. Creating new cannabis crosses requires pollen from a male plant. Non-feminized seeds are the only reliable way to produce male plants, which makes them essential for any breeding project. Feminized seeds are specifically engineered to suppress male expression and cannot be used for this purpose.
- Pheno-hunting. Running a large batch of non-feminized seeds from the same strain gives you a wide genetic range to evaluate — both male and female plants. Breeders and serious growers use this process to find an exceptional individual phenotype to keep as a mother plant or use in future crosses.
- Preserving classic genetics. Some heirloom and landrace strains are only available in regular (non-feminized) form. Reproducing these varieties across generations requires both male and female plants — which means non-feminized seeds are the only option for long-term preservation work.
- Personal preference for unmodified genetics. Some growers simply prefer to work with seeds in their natural form, without any selective breeding process applied to the sex ratio. Non-feminized seeds offer that.
Non-Feminized vs Feminized Seeds
Side by side — the practical differences.
| Non-Feminized (Regular) | Feminized | |
|---|---|---|
| Sex of plants | ~50% female / ~50% male | Female only (99%+) |
| Males present? | Yes — need to be identified and removed (unless breeding) | No — every plant contributes to harvest |
| Flowering trigger | Photoperiod (light schedule) | Photoperiod (light schedule) |
| Genetic quality | Same as feminized from the same strain | Same as regular from the same strain |
| Suitable for breeding | Yes — males available for crossing | No — no reliable male plants |
| Best for | Breeders, pheno-hunters, genetics preservation | Home growers, maximum yield, every seed counts |

How to Sex Non-Feminized Plants
Sexing is the one extra job non-feminized seeds add to a grow, and it is simpler than it sounds. Preflowers appear at the nodes — where a branch meets the main stem — roughly one to two weeks after the switch to 12/12, and sometimes late in vegetative growth on vigorous plants.
- Male preflowers look like small round balls on a short stalk, usually in tight clusters. They appear a few days earlier than female preflowers.
- Female preflowers are teardrop-shaped calyxes with one or two white hairs (pistils) emerging from the tip.
- When in doubt, wait. Two or three more days of growth makes the difference obvious. A magnifier or phone macro lens helps a lot at this stage.
Unless you are pollinating on purpose, remove males as soon as you identify them — a single open pollen sac in a sealed room can seed the whole crop. Move them well away from the flowering space before the sacs split rather than cutting them among the females.
Planning a Grow With Non-Feminized Seeds
Because roughly half your seedlings will be male, the arithmetic changes. Ten seeds realistically leave you around five females, which is a workable number for comparing phenotypes but a poor plan if you simply need four plants for a harvest.
A practical approach is to germinate more than you need, keep everything in small pots through early growth, and only move the confirmed females into their final containers. That way the space, light and nutrients go to plants that will actually produce.
Timing matters too: sexing costs one to two weeks of flowering time before you know what you have. In a short outdoor season that can be the difference between finishing and not, which is why most outdoor growers on tight timelines pick feminized or autoflowering seeds and leave non-feminized genetics for indoor projects where the calendar is under control.

FAQ: Non-Feminized Seeds
Are non-feminized seeds the same as regular seeds?
Yes. Non-feminized seeds and regular seeds are the same thing — cannabis seeds that have not been through the feminization process. They produce both male and female plants in roughly equal proportions, unlike feminized seeds which are bred to produce female plants only. In seed catalogues, these seeds are almost always listed under the "regular" category rather than "non-feminized," but the product is identical. The term "non-feminized" is simply a description of what the seeds are not, rather than a separate seed category.
Why would I buy non-feminized seeds?
The main reasons to buy non-feminized (regular) seeds are breeding and pheno-hunting. Breeding requires male plants to provide pollen for creating new crosses — feminized seeds are specifically engineered to avoid producing males, so non-feminized seeds are the only option. Pheno-hunting — running a large batch of seeds to find an exceptional individual phenotype — also benefits from the wider genetic variation that regular seeds provide. Some growers also buy non-feminized seeds to preserve heirloom or classic strains that are only available in regular form, or simply because they prefer to work with unmodified genetics.
How do you tell male and female plants apart?
Check the nodes about one to two weeks after switching to 12/12. Males show small round pollen sacs on a short stalk, usually in clusters; females show a teardrop calyx with one or two white pistils. Males typically declare themselves a few days earlier.
What percentage of non-feminized seeds are female?
Around half, though any single pack can land either side of that. Plan for roughly a 50:50 split and germinate more seeds than the number of plants you actually want to flower.
Can you grow non-feminized seeds outdoors?
You can, but the sexing window costs one to two weeks of the season. In short summers most growers choose feminized or autoflowering seeds outdoors and keep non-feminized genetics for indoor projects where timing is easier to control.
