Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, marked cheaper than the feminized packs beside it, and bought by a shrinking number of people who understand exactly what they are after. It is tempting to read that as the end of a technology. It is nearer to the truth to read it as a library shrinking while the paperback rack next door grows. Every female-only line began as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all exists only because somebody held onto regular seed. Specialists such as https://breederregularseeds.com carry lines going back 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 case for that half-male pack: what the male contributes, what a grower gives up by not growing one, and how to work with a population instead of a copy.
Not Just Pollen
The lazy description 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 that half is selected with the same attention as the female.
A male contributes growth habit, hybrid vigour, flowering speed, resistance to mould and pests, trichome production and the terpene profile just as the female does; it simply expresses several of those traits less visibly since it does not produce a smokable flower. Breeders who work with regular seed invest as much time selecting males as females, which is the effort that a feminized line borrows and can never replicate. Feminizing a female yields pollen; it does not provide a second set of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized market is made from S1 seeds: a one popular clone, reversed and pollinated with itself. Every generation of that process cuts in half the remaining genetic diversity, and after two generations what is left is essentially one plant expressed in marginally different ways.
This is acceptable for a grower who needs that single plant. It is a loss for everyone who comes after. Recessive faults emerge: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Traits that were present in the parent line but absent in the chosen clone disappear from the population altogether. A generation of such breeding leaves a market crowded with versions of the same few plants, and a breeder trying to create something new discovers there is little left to work with. Regular seed from an outcrossed line is the store that replenishes the pool, and that reservoir only exists as long as people keep growing it.
Selecting the Plant Nobody Writes About
Guides on selecting females are everywhere; guidance on picking males is scarce, because most growers never keep one long enough to judge. For a grower producing seed, the following are the signs breeders watch for.
- Stability. Any male that also shows female pistils under normal conditions is discarded outright; the tendency is the one thing worth carrying into a line.
- Restraint. Plants that dump enormous quantities of pollen all at once are often the least selected genetically; many breeders prefer moderate producers.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its sepals and a clear scent indicates it carries the resin traits that are worth keeping.
- Timing. A male that declares sex first and matures at the same pace as the females is more workable than an early one that releases pollen before any female is receptive.
- Structure. Tight internodes, a strong central stem and branching that matches the desired female habit are inherited; a lanky, weak-stemmed male passes that down too.
A Pack Is a Population
A mistake new regular-seed growers fall into is treating a pack as 10 chances at the one plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the point of running it is to observe the range and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields around five females to evaluate and five males to cull or judge for breeding. Within the females, expect noticeable variation: height, finishing time, smell, density, resistance. This variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and male has something a feminized pack cannot offer: a pair of selected parents which are theirs.
Making Your Own Seed
Owning chosen parents means making the next batch, and here the choices multiply. Three methods cover most of what home breeders attempt.
- Selected cross. One chosen male to one or several chosen females, everything else culled. The offspring carry the qualities of the two specific plants and show less variation than the parent pack. Done over several rounds with consistent selection, this is how a stable line is built.
- Backcross. Take a selected seedling again to one of its original parents to lock in a particular trait. It tightens the range quickly and is used when a single plant has something worth keeping and the second contributed mainly vigour.
- Open pollination. Let each male pollinate each female. It keeps the full diversity of the line, makes a large volume of seed, and does no choosing at all. This is how landrace lines are maintained alive, and it is the right approach when the goal is preservation rather than refinement.
Each of these require nothing more than a isolated space for the male, a paintbrush or a paper bag, and a few weeks. Not one of them needs the chemical reversal that feminized production does.
The Seeds That Only Exist as Regulars
Some lines were never feminized and likely never will be: landraces collected from regions where cannabis was grown over centuries, and old crosses from the first decades of indoor breeding. They are sold as regular seed because the people keeping them treat the population as the whole value, and reversing a single clone would erase exactly what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is different from growing a commercial hybrid. There will be large variation, long flowering times in equatorial lines, tall plants, and qualities that make sense in a field but not in a tent. There will be too aromas and effects that do not exist in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line marked with its origin of origin and the number of generations it has been grown out from the first collection.
The Honest Exclusions
Nothing of the above turns regular seed into the right choice for everyone, and pretending otherwise does the product no favours.
A grower with room for a handful of plants who needs each one of them to finish is far better off with feminized seed. So is a grower unable to inspect the plants every day around the onset 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 a buyer who wants a specific famous cut reproduced exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to hold onto and at some point to produce something new; for anyone else the regular shelf is best ignored where it is.
Ordering and the Law
Breeder Regular Seeds sends each order in plain packaging with the breeder’s packs intact inside and no on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law differs widely by country: in a good number of places buying seeds is lawful as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the rules where you live is the buyer’s job, and nothing of this article is legal advice.
