Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, priced cheaper 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 see that as obsolescence. It is nearer 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, every new cross requires a male at some point in its history, and the breadth of cannabis genetics that exists at all survives only because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a single plant. This article sets out the argument for that unfashionable pack: what the male contributes, what a buyer loses by not growing one, and how to get value with a population instead of a clone.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is “the one that makes pollen”, and for 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 mother.
A male passes on growth habit, hybrid vigour, maturation time, resistance to mould and pests, trichome density and the aromatic chemistry just as the female does; it simply shows several of those traits less visibly because it never grows a smokable flower. Those who breed with regular seed spend as much time choosing males as females, and this is the effort that a feminized line borrows and cannot replicate. Reversing a female yields pollen; it does not give a second set of selected genes.
How Diversity Leaks Away
A great deal of the feminized market is built from S1 seeds: a single famous clone, reversed and crossed with itself. Each round of that selfing cuts in half the remaining genetic variation, and after a couple of generations what is left is close to one plant expressed across slightly different ways.
This is fine for a grower who wants that one plant. It is a problem for everyone downstream. Hidden weaknesses surface: intersex tendencies, brittle stems, susceptibility to one particular mould. Qualities that existed in the original line but absent in the chosen clone vanish out of the gene pool entirely. A generation of this produces a market full with versions of a dozen clones, and a breeder trying to create something new discovers there is little remaining to work with. Regular seed from an outcrossed line is the reservoir that replenishes the market, and that reservoir only persist as long as people keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; guidance on choosing males is scarce, because most growers never keep one long enough to judge. For anyone making seed, these are the marks breeders look for.
- Timing. A male that declares sex first and matures in step with the females is more useful than an early one that releases pollen before the female is receptive.
- Stability. A male that at the same time forms female flowers under normal conditions is discarded outright; that trait is the one thing worth breeding into a line.
- Restraint. Males that release enormous amounts of pollen early are often also the less desirable genetically; breeders favour steady shedders.
- 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 scent suggests it carries the terpene traits that are worth keeping.
- Structure. Short internodes, a strong main stem and a frame that resembles the intended female habit are passed on; a stretched, floppy male passes that on too.
A Pack Is a Population
The error new 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 real outcrossed line is a sample of a population, and the point of growing it is to see the spread and choose from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields something like five females to compare and five males to either discard or judge for breeding. Among the females, expect noticeable differences: height, finishing time, smell, density, resistance. This variation is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and the best male now owns something a feminized pack cannot offer: a pair of selected parents that are theirs.
Making Your Own Seed
Holding chosen parents is only worth something if producing the next generation, and there the choices open up. Three methods account for most of what home breeders attempt.
- Open pollination. Allow every male reach each female. It preserves the whole range of the line, makes a generous quantity of seed, and involves no choosing at all. This is how landrace lines are kept going, and it is the correct method when the goal is preservation not improvement.
- Backcross. Take a selected offspring back to one of its original parents to lock in a specific trait. It narrows the range fast and is used when one parent has something worth concentrating and the other contributed mainly vigour.
- Selected cross. One picked male on one or a few chosen females, everything else removed. The offspring carry the qualities of two specific plants and show less variation than the original pack. Repeated over several rounds with consistent selection, this is how a new line is made.
Each of these require only a isolated space for the male, a soft brush or a paper bag, and patience. None of them needs the chemical treatment that feminized seed-making requires.
Landraces and Heirloom Lines
Some lines were never feminized and likely never will be: landraces gathered from places where cannabis grew over centuries, and old crosses from the early decades of modern breeding. They are available as regular seed since the breeders keeping them regard the population as the entire value, and reversing a single clone would erase exactly what makes the line worth preserving.
Growing a landrace from regular seed is different from growing a commercial hybrid. There will be large variation, long flowering times in tropical lines, lanky plants, and qualities that made sense in a mountain valley but not in a small room. There will be also flavours and chemistry that do not appear in the commercial market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line labelled with its region of collection and the number of generations it has been reproduced since the original collection.
The Honest Exclusions
None of the above makes regular seed into the right option for everyone, and claiming that it is would the product no favours.
A grower with room for a handful of plants who needs every one of them to flower is far better served with feminized seed. So is a grower unable to check the plants every day during the start of flower, since a missed male in a small space seeds everything within days. A person running a single autoflower on a balcony gets no value from a pack they cannot select from. And anyone who is after a known clone-only plant 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 produce something new; for anyone else the back shelf is safely ignored where it is.
Ordering and the Law
Breeder Regular Seeds sends each order in unmarked parcels with the breeder’s packs sealed inside and no on the exterior to reveal the contents. Orders to the United States are not accepted, because seed importation is not permitted there. Seed law differs widely by country: in a good number of places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are permitted under local rules or neither is. Checking the position in your own jurisdiction is the buyer’s job, and nothing of this article is legal advice.
