Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, priced lower than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are looking for. It is tempting to see that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the paperback rack next door expands. Every female-only line began as a regular one, each new cross needs a male somewhere in its history, and the diversity of cannabis genetics that exists at all exists only because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article sets out the argument for that unfashionable pack: what the male is for, what a buyer loses by not growing one, and how to work with a population rather than a copy.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and half is chosen with the same care as the female.
A male passes on growth habit, hybrid vigour, maturation time, tolerance to mould and pests, resin production and the aromatic chemistry exactly as the female does; it simply expresses several of those qualities less visibly since it does not grows a smokable flower. Those who work with regular seed spend as much time selecting males as females, and this is the effort that a feminized cross borrows and cannot repeat. Reversing a female gives pollen; it cannot provide a second line of selected genes.
How Diversity Leaks Away
Much of the feminized catalogue is built from S1 seeds: a one popular clone, reversed and crossed with itself. Every round of that selfing halves the surviving genetic diversity, and after a couple of generations what is left is essentially one plant repeated in slightly different ways.
That is fine for a consumer who wants that single plant. It is a problem for everyone downstream. Recessive faults emerge: intersex tendencies, brittle stems, susceptibility to a particular mould. Qualities that were present in the parent line but absent in the selected clone vanish out of the gene pool entirely. A decade of this leaves a market crowded with versions of the same few clones, and a anyone trying to create something different discovers there is little left to cross. Regular seed from an outcrossed line is the store that refills the market, and it can only persist if people grows it.
Selecting the Plant Nobody Writes About
Guides on choosing females are easy to find; guidance on picking males is rare, since most people never keep one past the first week of flower to judge. For a grower producing seed, these are the marks breeders look for.
- Resin on the stem. Rub a stem or a flower sac and smell it. A male with resin on its flower parts and a clear aroma indicates it holds the terpene genes that are worth passing on.
- Stability. Any male that at the same time shows female pistils under normal stress is discarded without exception; the trait is the last thing worth carrying forward.
- Timing. A male that declares sex early and flowers at the same pace as the females is more useful than a very early one that sheds pollen before the female is receptive.
- Structure. Short internodes, a thick central stem and branching that resembles the desired female shape are passed on; a stretched, floppy male passes that down too.
- Restraint. Plants that dump huge quantities of pollen all at once are frequently the less desirable genetically; many breeders favour moderate shedders.
Thinking in Numbers
The error new regular-seed growers fall into is treating a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a genuine outcrossed line is a sample of a population, and the value of running it is to see the range and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives something like five females to evaluate and five males to either cull or assess for breeding. Among the females, look for noticeable variation: stature, flowering time, smell, bud structure, tolerance. This variation is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and male now owns something a feminized pack can never offer: a line of selected parents which are theirs.
Three Ways to Cross
Owning chosen parents means making the next generation, and here the choices multiply. Three approaches cover most of what small-scale breeders attempt.
- Selected cross. One chosen male to one or several chosen females, everything else culled. The seeds inherit the traits of the two selected plants and express less variation than the parent pack. Done over generations with consistent choices, this is how a stable line is built.
- Backcross. Take a chosen seedling again to one of its original parents to fix a particular trait. It tightens the genetics fast and is useful when one parent shows something worth keeping and the second contributed mostly vigour.
- Open pollination. Let every male pollinate every female. It keeps the full range of the line, produces a generous volume of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the right method when the aim is preservation not refinement.
Each of these need nothing more than a isolated space for the male, a soft brush or a small bag, and patience. Not one of them needs the chemical reversal that feminized seed-making does.
The Seeds That Only Exist as Regulars
Some lines were never feminized and likely never will be: landraces collected from places where cannabis grew for centuries, and old crosses from the first decades of modern breeding. They are available as regular seed because the people maintaining them regard the population as the whole point, and selfing a single clone would erase exactly what makes the line worth the trouble of preserving.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect wide variation, extended flowering times in tropical lines, tall plants, and traits that made sense in a field but not under a small room. Expect too aromas and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its region of origin and the generation it has been reproduced since the first collection.
The Honest Exclusions
Nothing of the above turns regular seed the right choice for everyone, and claiming otherwise would the category no favours.
A grower with space for three plants who wants each one of them to flower is far better served with feminized seed. So is a grower unable to inspect the plants every day during the start of flower, because a missed male in a small space seeds everything inside days. Someone growing a single autoflower on a balcony has no use from a pack they cannot choose from. And anyone who wants a known famous cut reproduced exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to hold onto and at some point to produce something of their own; for everyone else the regular shelf is safely ignored where it is.
Ordering and the Law
Breeder Regular Seeds dispatches every order in plain packaging with the original packs intact inside and no on the outside to reveal the contents. Orders to the United States are not accepted, because seed importation is not permitted there. Seed law differs sharply by country: in a good number of places owning seeds is lawful as collectables while germinating them is not, and in others both are allowed under licence or neither is. Checking the rules in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
