Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, marked lower than the feminized packs next to it, and picked up by a dwindling number of people who understand exactly what they are looking for. It is easy to read that as the end of a technology. It is closer to the truth to see it as a library shrinking while the bookshop next door expands. Every feminized line began as a regular one, every new cross needs a male somewhere in its history, and the breadth of cannabis genetics that exists at all survives because somebody held onto regular seed. Specialists such as https://breederregularseeds.com stock 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 sets out the argument for that half-male pack: what the male is for, what a grower gives up by never seeing one, and how to get value with a population rather than a clone.
Not Just Pollen
The lazy description 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 selected with the same care as the female.
A male passes on growth habit, vigour, maturation time, resistance to mould and pests, trichome density and the terpene profile exactly as the female does; it simply expresses some of those qualities less visibly since it does not produce a smokable flower. Those who work with regular seed spend as much time choosing males as females, and this is the effort that a feminized line inherits and can never replicate. Reversing 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 built from S1 seeds: a one popular clone, reversed and pollinated with itself. Every round of that process cuts in half the surviving genetic diversity, and after two generations what is left is essentially one plant repeated in marginally different ways.
That is fine for a consumer who needs that one plant. It is a loss for everyone who comes after. Hidden weaknesses emerge: intersex tendencies, weak stems, susceptibility to a particular mould. Qualities that were present in the parent line but not in the selected clone disappear out of the population entirely. A decade of this produces a market full with versions of the same few plants, and a anyone wanting to make something different discovers there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the market, and it only exists as long as people keep growing it.
Reading a Male Plant
Articles on selecting females are easy to find; guidance on choosing males is rare, since most growers never keep one past the first week of flower to judge. For a grower producing seed, these are the marks breeders look for.
- Stability. A male that also forms female flowers under ordinary conditions is discarded outright; the trait is the last thing anyone wants breeding forward.
- Structure. Short internodes, a strong central stem and a frame that matches the intended female shape are passed on; a stretched, floppy male hands that down too.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its flower parts and a strong aroma indicates it holds the terpene traits that are worth keeping.
- Restraint. Males that release enormous amounts of pollen early are frequently also the less selected genetically; breeders prefer steady shedders.
- Timing. A male that shows sex first and matures at the same pace as the females is more useful than a very early one that releases pollen before any female is receptive.
What 10 Seeds Actually Give You
The error first-time regular-seed buyers make is seeing a pack as 10 chances at the one plant. It is nothing of the kind. 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 select from it.
Roughly half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to discard or judge for breeding. Among the females, expect real differences: height, finishing time, aroma, bud structure, tolerance. That variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male now owns something a feminized pack cannot supply: a line of chosen parents which are theirs.
Making Your Own Seed
Owning chosen parents means making the next generation, and there the choices open up. Three methods account for most of what home breeders attempt.
- Backcross. Cross a selected seedling back to one of its parents to fix a specific quality. It tightens the range fast and is useful when a single plant has something worth concentrating and the other contributed mainly vigour.
- Selected cross. One chosen male to one or several picked females, every other plant else culled. The offspring carry the qualities of two specific plants and express narrower spread than the parent pack. Done over several rounds with consistent selection, this is how a new line is made.
- Open pollination. Allow every male pollinate every female. It preserves the whole diversity of the line, produces a large quantity of seed, and involves no selection at all. This is how landrace lines are kept going, and it is the correct method when the goal is preservation rather than improvement.
Each of these need nothing more than a isolated space for the male, a soft brush or a paper bag, and patience. None of them needs the chemical reversal that feminized seed-making does.
The Seeds That Only Exist as Regulars
Some lines have never been feminized and likely never will be: landraces gathered from places where cannabis grew for centuries, and old hybrids from the early decades of indoor breeding. They are available as regular seed because the breeders keeping them regard diversity as the entire point, and selfing a single plant would destroy exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from running a modern hybrid. Expect wide variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a field but not under a tent. There will be too flavours and effects that do not exist in the hybrid market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line marked with its origin of origin and the number of generations it has been reproduced from the original collection.
When the Library Is the Wrong Shop
Nothing of the above turns regular seed into the right choice for everyone, and pretending that it is does the category no service.
A grower with room for three plants who wants every one of them to finish is far better served with feminized seed. So is a grower unable to check the plants every day during the start of flower, because a late male in a small space ruins the whole crop inside days. Someone growing a single autoflower on a balcony gets no value from a pack they cannot choose from. And anyone who is after a specific famous plant repeated exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to choose, to hold onto and eventually to make something of their own; for everyone else the regular shelf is safely left where it is.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked packaging with the breeder’s packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed importation is not permitted there. Seed law differs sharply by country: in a good number of places buying seeds is lawful as genetic preservation while germinating them is not, and in others the two are allowed under licence or both is. Knowing the rules in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
