Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, marked lower than the feminized packs beside it, and bought by a dwindling number of people who know exactly what they are after. It is easy to see that as obsolescence. It is nearer to the truth to see it as a library shrinking while the bookshop next door grows. Every feminized line began as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives only because someone kept regular seed. Specialists such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a single plant. This article sets out the argument for that unfashionable pack: what the male contributes, what a grower gives up by not growing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The easy description of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. For a breeder it is half the genome of every seed that follows, and that half is selected with the same care as the mother.
A male contributes structure, hybrid vigour, maturation speed, tolerance to mould and pests, resin density and the aromatic profile exactly as the female does; it just expresses some of those qualities less visibly since it does not grows a smokable flower. Those who work with regular seed spend at least as much time choosing males as females, and this is the effort that a feminized cross inherits and can never replicate. Feminizing a female gives pollen; it cannot give a second line of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized catalogue is built from S1 seeds: a one popular clone, reversed and crossed with itself. Each generation of that selfing halves the surviving genetic diversity, and after two rounds what remains is close to one plant expressed across marginally different forms.
This is acceptable for a consumer who needs that single plant. It is a problem for everyone who comes after. Hidden faults emerge: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Qualities that existed in the parent line but absent in the selected clone vanish out of the population entirely. A decade of such breeding leaves a market crowded with versions of a dozen clones, and a breeder wanting to create something new discovers there is nothing left to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and it can only persist if somebody keep growing it.
Reading a Male Plant
Articles on choosing females are easy to find; advice on choosing males is scarce, since most people never keep one long enough to judge. For a grower making seed, these are the signs breeders watch for.
- Timing. A male that declares sex early and matures at the same pace as the females is far more workable than a very early one that releases pollen before the female is ready.
- Restraint. Males that release huge quantities of pollen all at once are often also the least selected genetically; breeders prefer moderate producers.
- Structure. Short internodes, a strong main stem and a frame that resembles the intended female habit are passed on; a stretched, floppy male passes that on too.
- Stability. Any male that at the same time shows female pistils under normal conditions is rejected outright; that trait is the last thing worth breeding into a line.
Thinking in Numbers
A mistake new regular-seed buyers make 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 slice of a population, and the value of growing it is to see the spread and choose from it.
Roughly half the plants will be male, so a pack of 10 seeds yields around five females to evaluate and five males to cull or judge for breeding. Within the females, look for real variation: height, finishing time, aroma, bud structure, resistance. That variation is not a failure in the seed; it is what the seed is for. The grower who keeps the strongest female and the best male now owns something a feminized pack cannot supply: a pair of chosen parents which are their own.
Making Your Own Seed
Owning selected parents is only worth something if producing the next generation, and there the choices multiply. Three methods cover most of what home breeders attempt.
- Open pollination. Allow every male reach every female. It keeps the full diversity of the line, makes a large quantity of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the correct approach when the aim is preservation rather than improvement.
- Backcross. Cross a chosen offspring again to one of its parents to lock in a specific trait. It narrows the genetics quickly and is useful when a single plant has something worth keeping and the other brought mostly vigour.
- Selected cross. One chosen male to one or several chosen females, everything else culled. The seeds carry the traits of two specific plants and express less variation than the original pack. Repeated over several rounds with consistent choices, this is how a new line is built.
All three require only a separate space for the male, a paintbrush or a small bag, and a few weeks. None of them needs the chemical treatment that feminized production does.
Landraces and Heirloom Lines
Some lines were never feminized and probably never will be: landraces collected from places where cannabis grew over centuries, and old hybrids from the early decades of indoor breeding. They are sold as regular seed since the breeders keeping them treat diversity as the whole point, and selfing a single plant would erase precisely what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is different from growing a modern hybrid. There will be large variation, extended flowering periods in tropical lines, lanky plants, and traits that make sense in a mountain valley but not under a tent. Expect too flavours and chemistry that do not appear in the commercial market anywhere. Breeder Regular Seeds holds 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 makes regular seed the best choice for everyone, and pretending otherwise would the category no favours.
A grower with space for a handful of plants who wants each one of them to flower is better served with feminized seed. So is anyone who cannot afford to check the plants every day during the start of flower, since a missed male in a confined space ruins the whole crop inside days. Someone growing a single autoflower on a balcony gets no use from a pack they cannot choose from. And anyone who wants a specific famous plant repeated as closely as possible is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to keep and at some point to make something of their own; for anyone else the regular shelf is safely ignored alone.
Before You Buy
Breeder Regular Seeds dispatches every order in plain parcels with the original packs sealed inside and nothing on the outside to indicate the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law differs sharply by country: in many places owning seeds is legal as collectables while germinating them is not, and in others both are permitted under licence or both is. Checking the rules where you live is the buyer’s responsibility, and no part of this article is legal advice.
