Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, priced 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 closer to the truth to see it as a library losing shelves while the bookshop next door expands. Every feminized line began as a regular one, every new cross requires a male somewhere in its history, and the diversity of cannabis genetics that survives at all exists only because somebody kept regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a single plant. This article sets out the case for that unfashionable pack: what the male is for, what a grower loses by not seeing one, and how to work with a pack rather than a clone.
Not Just Pollen
The easy account 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 half is chosen with the same attention as the female.
A male contributes growth habit, vigour, maturation time, tolerance to mould and pests, trichome density and the terpene profile exactly as the female does; it simply expresses several of those traits less since it never produce a finished flower. Breeders who breed with regular seed invest as much time choosing males as females, which is the effort that a feminized line inherits and can never repeat. Reversing a female yields pollen; it does not provide a second line of selected traits.
How Diversity Leaks Away
Much of the feminized market is built from S1 seeds: a one famous clone, reversed and crossed with itself. Each round of that process halves the remaining genetic diversity, and after two generations what remains is close to one plant repeated in slightly different ways.
This is acceptable for a consumer who wants that one plant. It is a problem for everyone downstream. Recessive faults surface: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Qualities that were present in the original line but not in the selected clone disappear from the gene pool entirely. A decade of this leaves a market full with versions of a dozen plants, and a breeder wanting to create something new finds there is little remaining to cross. Regular seed from a true outcrossed line is the reservoir that refills the pool, and it can only exists as long as people grows it.
Reading a Male Plant
Guides on choosing females are everywhere; guidance on picking males is rare, since most growers do not keep one past the first week of flower to look. For a grower making seed, these are the marks breeders watch for.
- 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 holds the terpene genes worth passing on.
- Restraint. Males that dump huge amounts of pollen all at once are frequently the least desirable genetically; many breeders prefer steady shedders.
- Stability. A male that at the same time shows female flowers under ordinary stress is discarded without exception; the trait is the one thing worth carrying forward.
- Timing. A male that declares sex first and flowers at the same pace as the females is more useful than an early one that releases pollen before the female is receptive.
Thinking in Numbers
The error first-time regular-seed growers make is treating a pack as 10 attempts at the same plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the point of running it is to see the range and choose from it.
Roughly 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 judge for breeding. Within the females, expect real differences: height, finishing time, smell, density, resistance. This spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and the best male now owns something a feminized pack can never offer: a pair of chosen parents that are their own.
Making Your Own Seed
Holding chosen parents is only worth something if making the next batch, and here the choices open up. Three methods cover most of what small-scale breeders attempt.
- Open pollination. Let each male pollinate every female. It preserves the full diversity of the line, makes a large volume of seed, and involves no selection at all. This is how traditional lines are maintained going, and it is the right approach when the aim is preservation not refinement.
- Selected cross. One picked male to one or a few chosen females, every other plant else culled. The seeds inherit the traits of the two specific plants and express less variation than the parent pack. Done over generations with consistent choices, this is how a new line is built.
- Backcross. Take a selected seedling again to one of its original parents to lock in a particular quality. It narrows the genetics quickly and is used when a single parent shows something worth keeping and the other brought mostly vigour.
Each of these require nothing more than a separate space for the male, a soft brush or a paper bag, and a few weeks. Not one of them calls for the chemical treatment that feminized seed-making does.
Keeping Old Lines Alive
Some lines have never been feminized and probably never will be: landraces gathered from places where cannabis was grown for centuries, and old hybrids from the first decades of indoor breeding. They are available as regular seed since the breeders keeping them regard diversity as the entire value, and selfing a single clone would destroy precisely what makes the line worth preserving.
Running a landrace from regular seed is different from growing a commercial hybrid. There will be wide variation, long flowering times in tropical lines, lanky plants, and qualities that made sense in a mountain valley but not under a small room. There will be too flavours and chemistry that do not appear in the commercial market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its region of origin and the generation it has been grown out since the original collection.
The Honest Exclusions
None of the above turns regular seed the best choice for everyone, and pretending otherwise would the product no service.
A grower with space for three plants who needs each one of them to flower is better off with feminized seed. So is anyone unable to inspect the plants each day around the start of flower, because a missed male in a confined space ruins the whole crop inside days. A person growing a single autoflower on a balcony has no value from a population they cannot select from. And a buyer who wants a specific famous cut reproduced exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to choose, to keep and eventually to produce something of their own; for anyone else the regular shelf is best ignored where it is.
Before You Buy
Breeder Regular Seeds sends each order in unmarked parcels with the breeder’s packs sealed 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 sharply by country: in many places owning seeds is legal as collectables while germinating them is not, and in others both are permitted under local rules or both is. Checking the position where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
