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 next to it, and picked up by a shrinking group of people who understand exactly what they are after. It is tempting to see 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 grows. Every female-only line started as a regular one, each new cross needs a male at some point in its pedigree, and the diversity of cannabis genetics that survives at all survives only because somebody kept regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article sets out the argument for that unfashionable pack: what the male contributes, what a grower gives up by never seeing one, and how to work with a population rather than a copy.
Not Just Pollen
The easy 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 which follows, and that half is chosen with the same attention as the female.
A male passes on growth habit, hybrid vigour, maturation time, resistance to mould and pests, resin density and the terpene profile exactly as the female does; it just shows several of those qualities less since it never produce a finished flower. Breeders who work with regular seed invest as much time selecting males as females, and this is the effort that a feminized cross borrows and cannot replicate. Feminizing a female gives pollen; it does not give a second line of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is made from S1 seeds: a single popular clone, reversed and crossed with itself. Every generation of that process halves the remaining genetic variation, and after a couple of rounds what is left is essentially one plant repeated across slightly different ways.
That is acceptable for a consumer who wants that one plant. It is a loss for everyone downstream. Recessive faults surface: intersex tendencies, brittle stems, sensitivity to one particular mould. Traits that were present in the original line but absent in the chosen clone disappear from the gene pool entirely. A generation of such breeding leaves a market full with versions of a dozen clones, and a anyone trying to create something new finds there is little remaining to work with. Regular seed from an outcrossed line is the store that refills the pool, and that reservoir only persist if people keep growing it.
Selecting the Plant Nobody Writes About
Articles on choosing females are easy to find; guidance on choosing males is rare, since most people do not keep one long enough to judge. For a grower making seed, these are the marks breeders watch for.
- Stability. A male that at the same time forms female pistils under ordinary conditions is discarded outright; that tendency is the last thing worth breeding into a line.
- Structure. Short internodes, a strong central stem and branching that matches the intended female habit are passed on; a stretched, floppy male hands that down too.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with trichomes on its sepals and a strong aroma suggests it holds the terpene traits that are worth passing on.
- Restraint. Males that release huge amounts of pollen early are frequently the less desirable in other respects; many breeders prefer moderate shedders.
A Pack Is a Population
The error first-time regular-seed growers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a genuine outcrossed line is a slice of a population, and the point of growing it is to see the range and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields something like five females to evaluate and five males to either cull or assess for breeding. Within the females, look for real variation: height, flowering time, aroma, bud structure, resistance. This variation is not a flaw in the seed; it is what the seed is for. The grower who keeps the best female and the best male now owns something a feminized pack can never offer: a pair of selected parents which are their own.
Making Your Own Seed
Holding chosen parents means producing the next batch, and there the options multiply. The main approaches account for most of what home breeders do.
- Backcross. Take a selected offspring back to one of its parents to fix a specific quality. It tightens the range quickly and is used when one parent shows something worth concentrating and the other contributed mainly vigour.
- Open pollination. Let every male reach every female. It preserves the whole diversity of the line, produces a generous volume of seed, and does no choosing at all. This is how traditional lines are maintained going, and it is the right approach when the goal is preservation not improvement.
- Selected cross. One chosen male to one or a few chosen females, every other plant else removed. The seeds carry the qualities of the two selected plants and express less variation than the original pack. Done over generations with consistent selection, this is how a stable line is made.
All three require only a isolated space for the male, a soft brush or a paper bag, and a few weeks. None of them needs the chemical treatment that feminized seed-making does.
Keeping Old Lines Alive
A number of lines were never been feminized and likely never will be: landraces collected from regions where cannabis was grown for centuries, and old hybrids from the first decades of modern breeding. They are sold as regular seed because the people keeping them treat diversity as the entire point, and reversing a single clone would destroy precisely what makes the line worth preserving.
Running a landrace from regular seed is a different experience from running a modern hybrid. There will be large variation, extended flowering times in tropical lines, tall plants, and traits that make sense in a field but not under a tent. Expect too flavours and effects that do not exist in the commercial market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its origin of collection and the generation it has been reproduced since the original collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed into the best choice for everyone, and pretending otherwise would the category no favours.
A grower with room for three plants who wants each one of them to flower is better off with feminized seed. The same is anyone unable to check the plants every day around the start of flower, because a missed male in a small space ruins everything within days. A person running a single autoflower on a balcony has no value from a population they cannot choose from. And anyone who is after a specific clone-only plant repeated as closely as possible is 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 produce something new; for anyone else the regular shelf is safely left alone.
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 importation is restricted there. Seed law varies sharply by country: in many places owning seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under licence or both is. Knowing the rules where you live is the buyer’s job, and no part of this article should be read as legal advice.
