Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, priced lower than the feminized packs beside it, and bought by a shrinking number of people who know exactly what they are after. It is tempting to see that as obsolescence. It is nearer to the truth to read it as a library losing shelves while the paperback rack next door grows. Every feminized line began as a regular one, every new cross requires a male somewhere in its history, and the breadth of cannabis genetics that exists at all survives because somebody kept regular seed. Specialists such as https://breederregularseeds.com stock 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 makes the case for that half-male pack: what the male contributes, what a grower loses by not seeing one, and how to get value with a pack rather than a copy.
The Other Half of the Genome
The easy description of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is all it. To 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 passes on growth habit, hybrid vigour, maturation speed, resistance to mould and pests, resin production and the terpene chemistry just as the female does; it simply shows several of those qualities less visibly because it never grows a smokable flower. Those who work with regular seed invest as much time selecting males as females, which is the effort that a feminized line inherits and cannot repeat. Reversing a female yields pollen; it does not give a second set of selected traits.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a single popular clone, reversed and crossed with itself. Every generation of that process cuts in half the remaining genetic variation, and after a couple of rounds what is left is essentially one plant repeated in slightly different forms.
This is fine for a consumer who wants that one plant. It is a problem for everyone downstream. Hidden faults surface: intersex tendencies, weak stems, susceptibility to a particular mould. Qualities that were present in the original line but absent in the chosen clone disappear from the gene pool altogether. A generation of such breeding produces a market full with versions of the same few plants, and a breeder trying to make something new finds there is little remaining to work with. Regular seed from an outcrossed line is the reservoir that refills the market, and it can only persist if somebody keep growing it.
Selecting the Plant Nobody Writes About
Articles on selecting females are everywhere; guidance on choosing males is rare, because most people do not keep one long enough to judge. For a grower producing seed, the following are the signs breeders watch for.
- Timing. A male that declares sex first and matures in step with the females is far more workable than an early one that sheds pollen before any female is ready.
- Restraint. Males that release huge quantities of pollen all at once are often also the least desirable in other respects; many breeders favour moderate producers.
- Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong aroma suggests it carries the resin genes worth keeping.
- Structure. Short internodes, a strong central stem and a frame that matches the desired female habit are passed on; a lanky, floppy male hands that on too.
A Pack Is a Population
A error first-time regular-seed buyers fall into is seeing a pack as 10 attempts at the same plant. It is the opposite. A pack from a real outcrossed line is a sample of a population, and the value of growing it is to observe the spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds yields something like five females to compare and five males to either discard or assess for breeding. Among the females, look for noticeable differences: stature, flowering time, aroma, density, tolerance. This variation is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male has something a feminized pack cannot supply: a line of chosen parents that are their own.
From One Pack to the Next
Holding chosen parents is only worth something if producing the next generation, and here the choices open up. Three methods cover most of what small-scale breeders attempt.
- Selected cross. One picked male on one or several picked females, every other plant else culled. The seeds carry the qualities of the two specific plants and express less spread than the original pack. Done over generations with consistent choices, this is how a new line is made.
- Open pollination. Let every male reach each female. It keeps the whole range of the line, makes a generous volume of seed, and does no selection at all. This is how traditional lines are kept going, and it is the correct approach when the aim is preservation rather than improvement.
- Backcross. Cross a selected offspring back to one of its parents to lock in a particular quality. It tightens the range quickly and is useful when a single parent shows something worth keeping and the other brought mainly vigour.
Each of these require nothing more than a isolated space for the male, a soft brush or a paper bag, and patience. None of them calls for the chemical reversal that feminized production requires.
The Seeds That Only Exist as Regulars
A number of lines have never feminized and likely never will be: landraces gathered from regions where cannabis was grown over centuries, and heirloom hybrids from the early decades of indoor breeding. They are sold as regular seed because the breeders maintaining them regard diversity as the whole value, and reversing a single clone would destroy exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from running a modern hybrid. There will be large variation, extended flowering times in equatorial lines, lanky plants, and traits that made sense in a field but not in a tent. Expect too aromas and effects that do not appear in the hybrid market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its origin of collection and the number of generations it has been reproduced from the first collection.
Who Should Not Buy Regular Seeds
None of the above turns regular seed the best option for everyone, and pretending otherwise would the product no service.
A grower with space for three plants who wants every one of them to flower is far better off with feminized seed. So is a grower who cannot afford to inspect the plants every day during the start of flower, since a missed male in a confined space seeds the whole crop within days. A person growing a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who wants a known famous cut reproduced as closely as possible is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to keep and at some point to make something new; for anyone else the regular shelf is best left where it is.
Practicalities
Breeder Regular Seeds sends each order in plain parcels with the breeder’s packs intact inside and nothing on the exterior to reveal the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law differs widely by country: in many places owning seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or neither is. Knowing the rules in your own jurisdiction is the buyer’s job, and nothing of this article should be read as legal advice.
