Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower than the feminized packs next to it, and bought by a shrinking group of people who know exactly what they are looking for. It is tempting to read that as obsolescence. It is closer to the truth to read it as a library shrinking while the paperback rack next door grows. Every female-only line started 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 someone kept regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, sold in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article makes the argument for that half-male pack: what the male contributes, what a grower loses by never seeing one, and how to work with a pack rather than a clone.
What a Male Plant Is Actually For
The lazy account 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 that follows, and that half is chosen with the same care as the mother.
A male contributes structure, hybrid vigour, maturation speed, resistance to mould and pests, resin density and the terpene profile exactly as the female does; it just shows some of those traits less visibly since it never grows a smokable flower. Those who breed with regular seed invest as much time selecting males as females, and this is the effort that a feminized line borrows and can never repeat. Reversing a female gives pollen; it cannot provide a second line of selected traits.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and crossed with itself. Every round of that process halves the surviving genetic diversity, and after two rounds what is left is close to one plant repeated in marginally different ways.
This is acceptable for a consumer who needs that single plant. It is a problem for everyone downstream. Recessive faults emerge: intersex tendencies, brittle stems, sensitivity to one particular mould. Traits that existed in the original line but not in the selected clone disappear out of the gene pool altogether. A generation of such breeding produces a market full with variations of a dozen plants, and a breeder trying to create something new discovers there is nothing left to work with. Regular seed from an outcrossed line is the store that refills the pool, and that reservoir can only persist if somebody grows it.
How to Judge a Male
Articles on selecting females are easy to find; advice on picking males is rare, because most people never keep one long enough to look. For a grower producing seed, these are the signs breeders look for.
- Structure. Tight internodes, a thick main stem and branching that matches the intended female habit are passed on; a lanky, weak-stemmed male passes that on too.
- Timing. A male that declares sex early and flowers in step with the females is more workable than an early one that releases pollen before any female is ready.
- Restraint. Plants that dump huge amounts of pollen early are frequently also the less desirable in other respects; breeders favour moderate producers.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with trichomes on its sepals and a clear aroma indicates it holds the terpene traits worth keeping.
- Stability. Any male that also forms female flowers under ordinary stress is discarded without exception; the trait is the one thing worth carrying into a line.
A Pack Is a Population
The error new regular-seed buyers make 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 spread and choose from it.
About half the plants will be male, so a pack of 10 seeds gives around five females to compare and five males to either discard or assess for breeding. Within the females, expect noticeable variation: height, finishing time, aroma, bud structure, tolerance. This variation is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and male now owns something a feminized pack can never offer: a pair of chosen parents that are theirs.
Making Your Own Seed
Owning chosen parents means making the next generation, and there the choices open up. The main methods account for most of what small-scale breeders attempt.
- Selected cross. One chosen male to one or several chosen females, everything else removed. The offspring inherit the qualities of the two selected plants and express narrower variation than the parent pack. Repeated over generations with consistent choices, this is how a new line is made.
- Backcross. Cross a chosen seedling again to one of its original parents to fix a specific quality. It tightens the genetics quickly and is useful when a single plant shows something worth keeping and the second contributed mainly vigour.
- Open pollination. Allow each male pollinate every female. It keeps the full diversity of the line, produces a large volume of seed, and involves no selection at all. This is how landrace lines are maintained going, and it is the correct approach when the goal is preservation rather than refinement.
Each of these require nothing more than a isolated space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical reversal that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines have never feminized and likely never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom hybrids from the early decades of indoor breeding. They are available as regular seed since the people keeping them regard the population as the whole value, and selfing a single clone would destroy precisely what makes the line worth preserving.
Running a landrace from regular seed is a different experience from growing a commercial hybrid. There will be large variation, extended flowering times in equatorial lines, lanky plants, and traits that made sense in a mountain valley but not under a small room. There will be also aromas and effects that no longer appear in the commercial market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its region of collection and the generation it has been reproduced since the first collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed into the right choice for everyone, and pretending otherwise would the product no service.
A grower with space for three plants who needs every one of them to finish is far better served with feminized seed. So is anyone who cannot afford to inspect the plants each day around the start of flower, since a late male in a confined space seeds the whole crop inside days. Someone growing a single autoflower on a balcony has no use from a population they cannot select from. And anyone who is after a specific famous plant repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to choose, to keep and at some point to make something of their own; for everyone else the back shelf is safely ignored where it is.
Before You Buy
Breeder Regular Seeds dispatches each order in unmarked packaging with the original packs intact inside and no on the exterior to reveal the contents. Orders to the United States are not accepted, because seed importation is not permitted there. Seed law differs widely by country: in a good number of places owning seeds is lawful as genetic preservation while germinating them is not, and in others both are permitted under licence or neither is. Knowing the position where you live is the buyer’s responsibility, and no part of this article is legal advice.
