Regular Cannabis Seeds

Regular Seed Catalogue

Twenty-five regular lines, grouped by the job they are bought for rather than by alphabet. Every pack below is non-feminized: expect roughly half male plants, and expect to sex them. Feminized, S1 and autoflowering stock is filtered out of this listing entirely.

Breeding foundationsStable, documented lines with published lineage — the safest starting point for a first cross.

Pheno-hunt packsWider crosses and larger packs — bought for variance, not for uniformity.

Landrace & preservationLines kept in unmodified form — judged on documented provenance rather than on a THC figure.

Outdoor-readyLines that finish inside a normal outdoor season, selected on flowering time and resilience.

What Are Regular Cannabis Seeds?

Regular seeds are what a male plant and a female plant make together. Pollen released from ripe sacs on a male reaches the stigmas of a female flower, and the seeds that ripen inside that flower carry genetic material from both parents. Nothing is added, removed or reversed along the way, which is why regular marijuana seeds are sometimes described as unsexed or non-feminized seeds — the sex of each plant is still an open question written into its own chromosomes.

Because the full chromosome set is intact, each seed has an approximately even chance of growing into a male or a female. The plant itself does not settle the question until the light cycle changes and flowering begins. Up to that point a seedling from a regular pack behaves exactly like any other seedling: it roots, it stretches, it builds foliage, and it gives away nothing about what it will become.

Nothing on the outside of a seed reveals its sex. Size, colour, stripe pattern and shell hardness are markers of maturity and storage condition, not of gender, and every method claiming otherwise fails under controlled observation. Sex is read from the plant at the nodes, weeks later.

Regular seed now accounts for only a small slice of the cannabis seed market — Dutch Passion, which pioneered feminized seed in the 1990s, puts the figure at around two per cent of total sales. That number is worth reading correctly. It does not describe a declining product; it describes a specialist one, bought almost entirely by people with a specific technical reason to buy it.

Regular vs Feminized vs Autoflower: Which Should You Buy?

Buy regular seeds for breeding, pheno hunting or preserving a line. Buy feminized seeds when every plant in the tent needs to produce flower. Buy autoflower seeds for speed, small spaces and a schedule that does not depend on managing a light cycle.

The comparison is about task, not quality. Feminized seed carries a small residual risk of hermaphroditism traced to the reversal process used to make it; regular seed removes that particular variable but replaces it with the labour of sexing. Autoflowering lines begin flowering on age rather than on light schedule, which makes them fast and forgiving but leaves the grower with far less control over plant size and vegetative time. None of the three is a better seed. They are three answers to three different questions.

Pros and Cons of Regular Cannabis Seeds

Looking only at regular seed, and setting the other seed types aside, the advantages and the costs both come from the same source: nothing has been done to the genetics.

Why Breeders and Pheno Hunters Choose Regular Seeds

The fifty-fifty split reads as waste to a grower counting harvested plants and as raw material to anyone building something. Four distinct jobs depend on it, and each one has different requirements from a pack.

How Many Female Plants Will You Get?

On average, about half. The honest version of that answer is more useful: sex is decided independently for each plant, so a pack does not distribute males and females evenly the way a deck of cards distributes suits. A ten-seed pack commonly yields somewhere between three and seven females. Four is unremarkable. So is six. Two and eight are both entirely possible and neither indicates a fault with the seed.

Some growers report that higher humidity or a blue-weighted spectrum during early growth nudges the ratio towards females. These reports are anecdotal. No established mechanism supports them, results are not reproducible across grows, and no seed bank can promise a ratio on that basis. Treating them as a planning assumption leads to short harvests.

The reliable planning method is arithmetic, not environmental control: start more seeds than the number of females required, and size the surplus to the level of confidence needed. The two tables below set out those odds. All percentages in this section are calculated values, derived from a 50 % chance of female per plant and assuming every seed germinates; they are not observations from a trial.

How to Tell Male From Female Plants

Sexing cannabis plants is a matter of knowing where to look, when to look, and what the two signs actually look like at the size they first appear — which is small. The difference between a male vs female cannabis plant is visible at the nodes long before it is visible anywhere else, and the cost of missing it is measured in a whole room of seeded flower.

Where and when sex shows

Sex is read at the nodes — the junctions where a branch meets the main stem. Pre-flowers often appear there from roughly the fourth to sixth week of vegetative growth, ahead of any light change, and they are the earliest available signal. After the switch to a 12/12 light cycle, sex becomes clearly readable within one to three weeks on most photoperiod lines. Sativa-leaning plants tend towards the later end of that window.

What to look for

Male pre-flowers form as small round or slightly spade-shaped sacs sitting on a short stalk, usually clustered at the node. Female pre-flowers are teardrop-shaped and produce one or two fine white pistils from the tip. The shapes are unambiguous once seen, but at first appearance both are a couple of millimetres across, which is why growers inspect at close range rather than glancing across the tent.

When to remove males

Males are removed as soon as sex is confirmed — in practice the first or second week after the light switch, and always before the sacs open. A single male that releases pollen can seed an entire crop, so the margin for delay is thin. Where a plant is genuinely ambiguous, the better move is to isolate it in a separate space for a day or two rather than either guessing or leaving it in place. Growers making their own seed keep the male, but keep it isolated and control the pollination deliberately.

Growing Regular Seeds Step by Step

Growing regular cannabis seeds is identical to growing feminized seeds in every respect but one. Germination is the same, the vegetative stage is the same, feeding and lighting are the same, and the finish is the same. The single difference is a period of daily inspection in early flower and the removal of the males it identifies.

1. 2–3 days, occasionally 1–2 weeks

   Germination

   Reliable methods are a damp paper towel, a moist cotton pad, or sowing directly into the growing medium. The environment wants to be warm, dark and damp rather than wet, with temperatures around 21–27 °C (70–80 °F). Once a seed cracks and a white taproot emerges, it goes into the medium roughly a quarter of an inch deep, taproot down. Quality seed banks cold-store stock before dispatch and expect germination rates above ninety per cent.

2. 3–8 weeks

   Seedling and vegetative stage

   Seedlings want higher humidity and gentler light than mature plants. Most growers run 18 hours of light or more through veg, in soil, coco or hydroponics without adjustment for seed type. The two errors that cost the most at this stage are overwatering and overfeeding, both of which stall root development in a way that is slow to reverse. Regular seed asks for no special treatment here.

3. 1–3 weeks after the switch

   Switching to 12/12 and sexing

   Twelve hours of light and twelve of uninterrupted darkness triggers flowering and makes sex readable. This is the stage that separates regular from every other seed type, and it is worked through in detail in the sexing section above: check the nodes daily, confirm before acting, remove males before the sacs open, isolate anything uncertain rather than guessing.

4. 6–14 weeks of flower

   Finishing the females

   With the males gone, the remaining females ripen on a normal schedule — around seven to nine weeks for indica-leaning lines, ten to fourteen for long-flowering sativas and hazes. This is also the stage at which a mother plant is chosen: the female that stands out on structure, resin and aroma is the one worth taking cuttings from before harvest, not after.

Reading a Seed Pack: F1, F2, BX, S1 and IBL Explained

Breeder shorthand appears in the name of almost every pack on the market and is almost never explained. It describes the breeding history of the line, and it predicts how much variation to expect inside the pack — which makes it the most practical piece of information on the label.

F1

First filial generation — the direct offspring of two distinct parent lines. Expect strong hybrid vigour with noticeable variation between plants. A good starting point for a hunt.

F2–F5

Successive generations made by crossing siblings from the previous one. Variation typically widens at F2, then narrows through F3 and beyond as the breeder selects. Higher numbers usually mean a more settled line.

BX1–BX4

Backcross — the line crossed back to one of its own parents, repeatedly. The backcrossed parent's traits dominate more strongly with each step. BX3 leans heavily towards that parent.

S1

Selfed — a female pollinated with reversed pollen from itself. The result is feminized offspring, not regular. S1 packs contain effectively no males and cannot supply pollen for a cross.

IBL

Inbred line — many generations of selection towards uniformity. The most predictable option available. Little to hunt through, which is the point.

(R) or REG

Regular, non-feminized. Roughly half male, half female. The marker to look for on this page.

10pk, 12pk, 17pk

Seed count in the pack. This directly sets how wide a hunt can be. Larger packs are bought for variance, not for volume.

Choosing Regular Seeds for Your Project

The right pack depends entirely on what it is for. A line that is perfect for holding genetics steady is the wrong purchase for a hunt, and vice versa. Four common projects and what each one should be looking for.

Budget is a legitimate filter too. Regular packs on the open market run from under thirty dollars to several hundred, and cheap regular cannabis seeds from established breeders are a sensible way to learn a technique before committing to an expensive line. The catalogue above groups its packs by exactly these four projects.

Storing Regular Seeds for the Long Term

Seeds are alive and slowly spending a fixed reserve. Storage does not add to that reserve; it only slows the rate at which it is used. Four conditions do almost all of the work: cool, dark, dry and — the one most often overlooked — stable.

Fluctuation is more damaging than a consistently warm shelf. Repeated cycles of warming and cooling drive moisture in and out of the seed coat, and that movement degrades viability faster than a steady room temperature ever will. A sealed container with a desiccant packet, kept somewhere that does not swing, outperforms a fridge that is opened twenty times a day.

Labelling is preservation work in its own right. A line without a record of its breeder, its generation and the date it was received loses provenance long before it loses germination rate, and provenance is most of what makes an heirloom line worth holding. Seed age lowers germination rate regardless of care, so older stock is worth germinating in larger numbers.

Are Regular Cannabis Seeds Legal?

The answer depends on location, and location is more specific than country.

The short answer: it depends on where you are

Rules differ between countries, and inside several countries they differ again by state, province or region. Two questions that are often merged are in fact governed separately: whether cannabis seeds may be bought and possessed, and whether anything may legally be grown from them. A jurisdiction may permit one and prohibit the other. Verifying both, locally, before ordering is the buyer's responsibility and no seller's assurance replaces it.

United States: what changes in November 2026

Section 781 was enacted as part of the appropriations package signed on 12 November 2025 and takes effect one year later, on 12 November 2026. It changes the federal measurement standard from delta-9 THC to total THC — delta-9 plus THCA — and excludes viable seeds from plants that would exceed 0.3 % total THC from the federal definition of hemp. In practice that covers the large majority of what seed banks sell.

Two limits on its scope matter. Section 781 governs interstate commerce: it addresses how seeds move between states, not whether a resident may cultivate at home, which remains a question of state law in every case. And it is not retroactive — seeds bought and received before the effective date are unaffected by what happens after it.

The position is also not settled. Several bills before Congress would repeal the provision, delay implementation or narrow what it reaches, and draft appropriations text circulated in August 2026 would restrict its scope for a limited window. None has passed as of the review date above. Anyone relying on this should read the current text rather than any summary: the bill number is H.R. 5371, searchable at congress.gov, and the enacted language is the only authoritative source.

Souvenir status and buyer responsibility

Many seed banks sell into restrictive jurisdictions on the basis that ungerminated seed is a collectible or souvenir item containing no meaningful THC. That framing has held up in a number of places and is why seeds ship where cultivation does not. It is a commercial position, not a legal shield: it does not override local law, it does not authorise germination anywhere, and it does not transfer to the buyer any protection the buyer does not already have. Customs treatment varies widely, and some destinations cannot be shipped to at all.
