Browse through most seed shops today and the regular section is a shelf at the back: shorter every year, priced lower than the feminized packs beside it, and picked up by a shrinking group of people who know exactly what they are after. It is easy 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 started as a regular one, each new cross needs a male somewhere in its history, and the diversity of cannabis genetics that exists at all exists only because someone 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 intended to be a population, not a single plant. This article makes the argument for that half-male pack: what the male contributes, what a grower gives up by never seeing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The lazy account of a male cannabis plant is “a pollen source”, and to 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 attention as the mother.
A male passes on structure, vigour, maturation time, tolerance to mould and pests, trichome production and the terpene chemistry exactly as the female does; it simply expresses several of those qualities less because it never grows a smokable flower. Breeders who breed with regular seed spend at least as much time choosing males as females, and this is the effort that a feminized cross inherits and can never replicate. Feminizing a female gives pollen; it cannot give a different set of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized catalogue is made from S1 seeds: a one popular clone, reversed and pollinated with itself. Every generation of that selfing halves the remaining genetic diversity, and after two generations what remains is close to one plant expressed across marginally different forms.
This is acceptable for a consumer who wants that single plant. It is a problem for everyone downstream. Recessive faults emerge: intersex tendencies, brittle stems, sensitivity to one particular mould. Qualities that existed in the parent line but not in the chosen clone vanish out of the population entirely. A decade of this leaves a market crowded with variations of the same few plants, and a anyone trying to make something new finds there is little remaining to cross. Regular seed from a true outcrossed line is the store that refills the market, and that reservoir only exists if people keep growing it.
Reading a Male Plant
Guides on selecting females are everywhere; advice on picking males is rare, since most people do not keep one past the first week of flower to judge. For a grower producing seed, the following are the signs breeders look for.
- Structure. Short internodes, a thick main stem and branching that resembles the desired female shape are passed on; a lanky, weak-stemmed male passes that down too.
- Timing. A male that declares sex early and matures at the same pace as the females is far more useful than an early one that sheds pollen before the female is ready.
- Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a strong aroma indicates it carries the resin traits worth passing on.
- Stability. Any male that at the same time shows female pistils under ordinary stress is discarded without exception; that trait is the last thing worth breeding into a line.
Thinking in Numbers
The error new regular-seed buyers fall into is treating a pack as 10 chances at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the point of growing it is to see the range and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives around five females to compare and five males to cull or assess for breeding. Within the females, expect noticeable differences: stature, flowering time, smell, density, tolerance. This variation is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the best female and male has something a feminized pack cannot supply: a pair of chosen parents which are theirs.
From One Pack to the Next
Holding chosen parents means producing the next batch, and there the choices multiply. The main methods cover most of what small-scale breeders attempt.
- Selected cross. One picked male to one or a few picked females, everything else culled. The offspring carry the traits of two selected plants and show less variation than the parent pack. Repeated over several rounds with consistent selection, 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 quickly and is useful when a single parent has something worth keeping and the second contributed mostly vigour.
- Open pollination. Let each male pollinate every female. It keeps the whole diversity of the line, produces a large volume of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the correct approach when the aim is preservation not improvement.
Each of these require nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. Not one of them needs the chemical treatment that feminized seed-making requires.
Landraces and Heirloom Lines
Some lines were never been feminized and likely never will be: landraces gathered from places where cannabis grew over centuries, and old hybrids from the first decades of indoor breeding. They are available as regular seed since the people maintaining them regard the population as the entire value, and selfing a single clone would destroy exactly what makes the line worth the trouble of keeping.
Running a landrace from regular seed is a different experience from running a modern hybrid. Expect large variation, extended flowering times in tropical lines, lanky plants, and traits that make sense in a field but not under a small room. There will be too flavours and effects that do not appear in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line marked with its origin of origin and the generation it has been grown out since the original collection.
When the Library Is the Wrong Shop
Nothing of the above turns regular seed into the right option for everyone, and claiming that it is does the category no favours.
A grower with space for a handful of plants who wants each one of them to finish is better served with feminized seed. So is a grower unable to inspect the plants every day during the onset of flower, because a late male in a confined space seeds the whole crop within days. A person running a single autoflower on a balcony has no use from a population they cannot choose from. And a buyer who is after a known clone-only cut repeated exactly is better off 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 make something of their own; for anyone else the back shelf is best ignored alone.
Before You Buy
Breeder Regular Seeds sends each order in plain packaging with the breeder’s packs intact inside and no on the outside to reveal the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law differs widely by country: in a good number of places buying seeds is lawful as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Checking the position in your own jurisdiction is the buyer’s job, and no part of this article is legal advice.
