Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked cheaper than the feminized packs beside it, and picked up by a shrinking group of people who know exactly what they are looking for. It is easy to see that as obsolescence. It is closer to the truth to read it as a library losing shelves while the paperback rack next door grows. Every female-only line began as a regular one, every new cross needs a male somewhere in its history, and the diversity of cannabis genetics that survives at all exists because somebody kept regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article sets out the case for that unfashionable pack: what the male contributes, what a grower gives up by never seeing one, and how to work with a population instead of a copy.
The Other Half of the Genome
The lazy description of a male cannabis plant is «a pollen source», and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and that half is chosen with the same attention as the mother.
A male passes on growth habit, hybrid vigour, maturation time, tolerance to mould and pests, resin production and the aromatic profile just as the female does; it just shows some of those qualities less since it does not produce a finished flower. Breeders who breed with regular seed spend as much time selecting males as females, and this is the effort that a feminized cross inherits and can never replicate. Feminizing a female yields pollen; it does not give a different set of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one popular clone, reversed and pollinated with itself. Each round of that process halves the surviving genetic variation, and after a couple of rounds what remains is close to one plant repeated in slightly different ways.
This is fine for a consumer who needs that one plant. It is a problem for everyone downstream. Hidden faults surface: hermaphrodite tendencies, brittle stems, sensitivity to one particular mould. Qualities that existed in the parent line but not in the chosen clone vanish from the gene pool entirely. A generation of this produces a market crowded with versions of the same few plants, and a breeder wanting to create something different discovers there is little left to work with. Regular seed from a true outcrossed line is the store that replenishes the market, and that reservoir can only persist as long as people keep growing it.
Selecting the Plant Nobody Writes About
Articles on choosing females are everywhere; advice on picking males is scarce, since most growers do not keep one past the first week of flower to look. For a grower producing seed, these are the marks breeders look for.
- Timing. A male that declares sex first and flowers in step with the females is far more workable than a very early one that sheds pollen before any female is receptive.
- Stability. A male that also forms female flowers under normal conditions is rejected without exception; the tendency is the one thing anyone wants carrying forward.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with resin on its sepals and a strong aroma indicates it carries the terpene genes worth keeping.
- Restraint. Males that dump enormous amounts of pollen early are frequently the less desirable genetically; breeders favour moderate shedders.
A Pack Is a Population
The error first-time regular-seed growers make is seeing a pack as 10 attempts at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the point of running it is to see the spread and choose from it.
Roughly half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to either discard or assess for breeding. Within the females, expect noticeable differences: height, flowering time, aroma, density, resistance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who takes cuttings from the best female and male now owns something a feminized pack can never offer: a line of chosen parents that are their own.
From One Pack to the Next
Owning chosen parents means producing the next generation, and here the options open up. The main approaches cover most of what small-scale breeders do.
- Open pollination. Allow every male pollinate each female. It preserves the whole diversity of the line, makes a large quantity of seed, and involves no choosing at all. This is how traditional lines are maintained going, and it is the correct approach when the aim is preservation not improvement.
- Selected cross. One chosen male to one or several chosen females, every other plant else removed. The seeds carry the traits of the two selected plants and show narrower variation than the parent pack. Done over generations with stable choices, this is how a stable line is made.
- Backcross. Cross a chosen offspring again to one of its parents to fix a specific quality. It narrows the range fast and is useful when a single parent shows something worth concentrating and the second contributed mainly vigour.
Each of these need only a separate space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical treatment that feminized seed-making does.
Landraces and Heirloom Lines
Some lines have never been feminized and likely never will be: landraces collected from places where cannabis grew for centuries, and heirloom crosses from the first decades of modern breeding. They are available as regular seed since the people maintaining them regard the population as the entire point, and reversing a single clone would destroy precisely what makes the line worth the trouble of preserving.
Running a landrace from regular seed is a different experience from running a modern hybrid. There will be large variation, extended flowering periods in tropical lines, lanky plants, and traits that made sense in a mountain valley but not in a tent. Expect too flavours and chemistry that no longer exist in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line marked with its region of origin and the number of generations it has been reproduced from the original collection.
When the Library Is the Wrong Shop
None of the above turns regular seed into the best option for everyone, and claiming that it is would the category no favours.
A grower with space for a handful of plants who needs every one of them to finish is better served with feminized seed. The same is a grower unable to check the plants every day around the onset of flower, because a missed male in a small space ruins everything within days. A person growing a single autoflower on a balcony gets no use from a population they cannot choose from. And anyone who is after a specific famous plant repeated as closely as possible is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to hold onto and at some point to produce something of their own; for anyone else the back shelf is safely ignored where it is.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked packaging with the original packs intact inside and no on the outside to indicate the contents. Orders to the United States are not accepted, because seed import is not permitted there. Seed law varies sharply by country: in a good number of places buying seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or both is. Checking the position in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.
