Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are after. It is tempting to see that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the bookshop next door grows. Every feminized line started as a regular one, each new cross needs a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives only because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a single plant. This article makes the argument for that half-male pack: what the male contributes, what a buyer loses by not growing one, and how to get value with a population instead of a copy.
The Other Half of the Genome
The easy account of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and half is selected with the same attention as the mother.
A male passes on structure, vigour, maturation speed, tolerance to mould and pests, trichome production and the aromatic profile exactly as the female does; it just shows several of those traits less visibly since it never produce a finished flower. Those who breed with regular seed invest at least as much time selecting males as females, and this is the work that a feminized cross inherits and cannot replicate. Feminizing a female yields pollen; it does not give a second set of selected traits.
The Narrowing
Much of the feminized catalogue is made from S1 seeds: a single popular clone, treated and pollinated with itself. Each generation of that process halves the surviving genetic diversity, and after a couple of rounds what remains is essentially one plant expressed across marginally different ways.
This is acceptable for a grower who wants that single plant. It is a problem for everyone who comes after. Recessive faults surface: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Traits that existed in the parent line but not in the chosen clone disappear from the gene pool altogether. A generation of such breeding leaves a market full with versions of a dozen plants, and a anyone trying to create something new finds there is nothing remaining to work with. Regular seed from an outcrossed line is the reservoir that replenishes the market, and that reservoir only persist if somebody keep growing it.
Selecting the Plant Nobody Writes About
Articles on choosing females are everywhere; advice on choosing males is scarce, because most growers do not keep one long enough to look. For a grower producing seed, these are the signs breeders watch for.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its sepals and a clear scent suggests it carries the terpene genes worth passing on.
- Stability. Any male that also forms female pistils under normal stress is discarded without exception; the tendency is the one thing anyone wants carrying into a line.
- Restraint. Plants that release enormous amounts of pollen all at once are frequently the less selected in other respects; many breeders favour moderate producers.
- Structure. Tight internodes, a thick main stem and a frame that matches the desired female habit are inherited; a lanky, weak-stemmed male hands that down too.
- Timing. A male that shows sex first and matures at the same pace as the females is far more workable than a very early one that releases pollen before any female is receptive.
Thinking in Numbers
The mistake first-time regular-seed growers fall into is treating a pack as 10 attempts at the one plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the point of growing it is to observe the spread and select from it.
About half the plants will be male, so a pack of 10 seeds yields around five females to compare and five males to either discard or judge for breeding. Within the females, expect real differences: stature, flowering time, aroma, bud structure, 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 has something a feminized pack cannot offer: a line of selected parents which are their own.
From One Pack to the Next
Owning selected parents means making the next generation, and here the choices multiply. Three methods account for most of what small-scale breeders do.
- Selected cross. One chosen male on one or a few picked females, every other plant else culled. The seeds carry the traits of two specific plants and express less spread than the original pack. Repeated over generations with stable selection, this is how a stable line is made.
- Backcross. Take a chosen seedling again to one of its original parents to lock in a particular trait. It tightens the genetics fast and is used when a single parent has something worth concentrating and the second brought mostly vigour.
- Open pollination. Let every male pollinate each female. It preserves the full range of the line, produces a generous quantity of seed, and involves no selection at all. This is how landrace lines are maintained going, and it is the correct approach when the aim is preservation not refinement.
All three need only a isolated space for the male, a soft brush or a paper bag, and a few weeks. Not one of them needs the chemical treatment that feminized production does.
Keeping Old Lines Alive
Some lines have never been feminized and likely never will be: landraces collected from places where cannabis grew over centuries, and old hybrids from the early decades of indoor breeding. They are sold as regular seed since the people maintaining them treat the population as the whole point, and reversing a single clone would destroy exactly what makes the line worth preserving.
Growing a landrace from regular seed is different from running a commercial hybrid. There will be large variation, extended flowering times in equatorial lines, lanky plants, and qualities that make sense in a mountain valley but not in a small room. There will be too aromas and chemistry that no longer exist in the hybrid 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 from the first collection.
The Honest Exclusions
Nothing of the above makes regular seed into the right option for everyone, and claiming that it is would the category no service.
A grower with space for a handful of plants who wants each one of them to flower is far better off with feminized seed. The same is a grower who cannot afford to check the plants every day around the onset of flower, because a late male in a confined space ruins the whole crop within days. Someone running a single autoflower on a balcony gets no value from a population they cannot select from. And a buyer who wants a specific clone-only plant reproduced as closely as possible 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 eventually to produce something of their own; for everyone else the regular shelf is safely left alone.
Ordering and the Law
Breeder Regular Seeds dispatches each order in unmarked parcels with the original packs sealed inside and nothing on the outside to reveal the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law differs sharply by country: in many places owning seeds is legal as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Knowing the position where you live is the buyer’s responsibility, and nothing of this article is legal advice.
