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 dwindling group of people who understand exactly what they are looking for. It is tempting to see that as obsolescence. It is closer to the truth to read it as a library shrinking while the bookshop next door expands. Every female-only 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 held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article makes the case for that unfashionable pack: what the male is for, what a grower gives up by not seeing one, and how to get value with a population 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 to a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and that half is chosen with the same attention as the mother.
A male contributes growth habit, hybrid vigour, flowering time, tolerance to mould and pests, resin production and the aromatic chemistry exactly as the female does; it just shows some of those traits less visibly since it does not produce a smokable flower. Those who work with regular seed invest as much time choosing males as females, and this is the effort that a feminized cross inherits and cannot replicate. Feminizing a female yields pollen; it does not provide a different set of selected traits.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a single famous clone, treated and pollinated with itself. Each round of that selfing cuts in half the surviving genetic diversity, and after a couple of rounds what is left is essentially one plant repeated across marginally different forms.
That is fine for a grower who wants that single plant. It is a loss for everyone downstream. Hidden faults emerge: intersex tendencies, brittle stems, susceptibility to a particular mould. Traits that were present in the original line but absent in the chosen clone vanish from the gene pool entirely. A generation of such breeding leaves a market crowded with variations of the same few plants, and a anyone wanting to make something different finds there is nothing remaining to cross. Regular seed from a true outcrossed line is the store that refills the market, and it can only persist if people grows it.
Reading a Male Plant
Articles on selecting females are easy to find; advice on picking males is rare, because most people never keep one past the first week of flower to look. For a grower making seed, these are the signs breeders look for.
- Resin on the stem. Rub a stem or a flower sac and smell it. A male with trichomes on its flower parts and a strong aroma suggests it carries the terpene traits worth passing on.
- Stability. Any male that at the same time shows female flowers under normal stress is rejected without exception; that trait is the one thing worth breeding into a line.
- Structure. Short internodes, a thick main stem and branching that resembles the intended female shape are inherited; a lanky, weak-stemmed male passes that down too.
- Restraint. Males that dump huge amounts of pollen early are frequently also the less desirable in other respects; breeders prefer steady producers.
- Timing. A male that shows sex first and flowers at the same pace as the females is more useful than an early one that sheds pollen before any female is receptive.
What 10 Seeds Actually Give You
The mistake first-time regular-seed growers fall into is seeing a pack as 10 chances at the one plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the value of growing it is to see the range and select from it.
About 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 discard or assess for breeding. Among the females, expect real differences: stature, flowering time, aroma, bud structure, resistance. That variation is not a flaw in the seed; it is what the seed is for. The grower who keeps the strongest female and male has something a feminized pack cannot supply: a pair of selected parents that are their own.
From One Pack to the Next
Owning chosen parents means making the next batch, and here the choices open up. The main approaches cover most of what home breeders attempt.
- Open pollination. Allow every male reach each female. It keeps the whole range of the line, makes a generous quantity of seed, and does no selection at all. This is how landrace lines are maintained going, and it is the right method when the aim is preservation not improvement.
- Selected cross. One picked male on one or several picked females, everything else culled. The seeds carry the traits of two specific plants and show narrower spread than the original pack. Repeated over generations with consistent choices, this is how a new line is built.
- Backcross. Cross a chosen offspring back to one of its original parents to lock in a specific quality. It tightens the range fast and is used when a single parent shows something worth concentrating and the other contributed mainly vigour.
All three require only 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 seed-making does.
The Seeds That Only Exist as Regulars
Some lines have never been feminized and probably never will be: landraces collected from regions where cannabis grew over centuries, and heirloom hybrids from the early decades of modern breeding. They are available as regular seed since the people keeping them regard diversity as the whole value, and reversing a single clone would erase exactly what makes the line worth preserving.
Growing a landrace from regular seed is different from running a commercial hybrid. Expect large variation, extended flowering times in tropical lines, lanky plants, and traits that made sense in a field but not in a tent. There will be too aromas and chemistry that do not exist in the hybrid market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line labelled with its region of origin and the generation it has been grown out since the first collection.
When the Library Is the Wrong Shop
Nothing of the above makes regular seed the right option for everyone, and claiming otherwise does the product no favours.
A grower with room for a handful of plants who needs every one of them to finish is better off with feminized seed. The same is anyone unable to check the plants every day during the onset of flower, since a missed male in a small space seeds the whole crop within days. A person running a single autoflower on a balcony has no use from a pack they cannot select from. And a buyer who wants a known famous plant repeated exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to hold onto and at some point to produce something of their own; for everyone else the regular shelf is safely left alone.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked parcels with the breeder’s packs intact inside and no on the outside to reveal the contents. Orders to the United States are not taken, because seed importation is not permitted there. Seed law differs widely by country: in a good number of places owning seeds is legal as collectables while germinating them is not, and in others both are permitted under licence or both is. Checking the position in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
