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 number of people who know exactly what they are looking for. It is tempting to read that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the bookshop next door expands. Every female-only line began as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives because someone held onto regular seed. Specialists 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 one plant. This article sets out the argument for that half-male pack: what the male is for, what a buyer gives up by not seeing one, and how to work with a population instead of a copy.
What a Male Plant Is Actually For
The easy description of a male cannabis plant is “a pollen source”, and to a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and half is selected with the same attention as the female.
A male passes on growth habit, vigour, maturation time, resistance to mould and pests, resin density and the aromatic chemistry just as the female does; it just shows some of those traits less visibly since it never produce a finished flower. Breeders who breed with regular seed invest at least as much time choosing males as females, which is the work that a feminized cross borrows and cannot repeat. Feminizing a female gives pollen; it does not provide a different line of selected genes.
The Narrowing
Much of the feminized market is made from S1 seeds: a single famous clone, treated and pollinated with itself. Every round of that selfing cuts in half the surviving genetic diversity, and after two generations what remains is essentially one plant expressed in slightly different ways.
This is acceptable for a consumer who needs that one plant. It is a loss for everyone who comes after. Hidden faults emerge: intersex tendencies, brittle stems, sensitivity to one particular mould. Qualities that existed in the original line but absent in the chosen clone vanish out of the gene pool altogether. A decade of such breeding leaves a market full with variations of the same few plants, and a breeder trying to make something new finds there is nothing remaining to cross. Regular seed from a true outcrossed line is the store that refills the pool, and that reservoir can only exists if people grows it.
Selecting the Plant Nobody Writes About
Articles on selecting females are easy to find; guidance on choosing males is scarce, because most growers do not keep one past the first week of flower to judge. For anyone producing seed, these are the marks breeders watch for.
- Timing. A male that shows sex first and flowers in step with the females is more useful than a very early one that sheds pollen before any female is ready.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with resin on its flower parts and a clear scent suggests it carries the terpene traits that are worth passing on.
- Structure. Short internodes, a strong central stem and a frame that resembles the intended female habit are inherited; a lanky, weak-stemmed male passes that on too.
- Stability. A male that at the same time shows female pistils under normal conditions is discarded without exception; that tendency is the last thing worth carrying forward.
- Restraint. Males that dump enormous quantities of pollen early are frequently also the less desirable in other respects; many breeders favour moderate producers.
What 10 Seeds Actually Give You
The error first-time regular-seed growers fall into is treating a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a genuine outcrossed line is a sample of a population, and the point of growing it is to see the spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds yields around five females to compare and five males to either discard or assess for breeding. Within the females, expect real differences: stature, flowering time, aroma, density, tolerance. This variation is not a flaw in the seed; it is what the seed is selling. The grower who takes cuttings from the best female and the best male now owns something a feminized pack can never supply: a pair of selected parents that are theirs.
From One Pack to the Next
Holding chosen parents is only worth something if producing the next generation, and there the choices open up. The main approaches account for most of what small-scale breeders do.
- Backcross. Take a selected seedling back to one of its parents to lock in a particular trait. It tightens the genetics fast and is used when one parent has something worth keeping and the other brought mainly vigour.
- Open pollination. Let each male reach every female. It preserves the full diversity of the line, makes a generous quantity of seed, and does no choosing at all. This is how landrace lines are maintained alive, and it is the right approach when the aim is preservation not improvement.
- Selected cross. One chosen male on one or several chosen females, everything else removed. The seeds carry the traits of two specific plants and express less spread than the original pack. Repeated over generations with consistent choices, this is how a stable line is made.
All three need only a separate space for the male, a paintbrush or a paper bag, and patience. None of them calls for the chemical treatment that feminized seed-making requires.
The Seeds That Only Exist as Regulars
A number of lines have never feminized and likely never will be: landraces collected from places where cannabis grew for centuries, and old hybrids from the first decades of indoor breeding. They are sold as regular seed since the people keeping them treat the population as the whole value, and reversing a single plant would destroy exactly what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is different from running a commercial hybrid. Expect large variation, extended flowering times in equatorial lines, lanky plants, and traits that made sense in a field but not under a tent. There will be also aromas and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, with each line labelled with its origin of collection and the generation it has been reproduced from the original collection.
When the Library Is the Wrong Shop
Nothing of the above turns regular seed into the best option for everyone, and claiming otherwise does the product no service.
A grower with space for three plants who wants every one of them to flower is better served with feminized seed. The same is a grower unable to check the plants each day during the onset of flower, because a missed male in a confined space ruins everything within days. A person growing a single autoflower on a balcony gets no value from a population they cannot choose from. And a buyer who is after a specific famous cut reproduced exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to choose, to keep and eventually to make something of their own; for everyone else the regular shelf is safely left alone.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked packaging with the breeder’s packs intact inside and nothing on the outside to indicate the contents. Orders to the United States are not taken, as seed import is restricted there. Seed law differs sharply by country: in a good number of places buying seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or both is. Knowing the position in your own jurisdiction is the buyer’s responsibility, and nothing of this article should be read as legal advice.
