Walk through most seed shops today and the regular section is a 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 tempting 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 grows. Every feminized line began as a regular one, every new cross requires a male somewhere in its history, and the diversity of cannabis genetics that survives at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry 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 case for that unfashionable pack: what the male is for, what a grower loses by not growing one, and how to work with a pack instead of a copy.
Not Just Pollen
The easy description of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and half is selected with the same care as the female.
A male passes on growth habit, hybrid vigour, flowering speed, resistance to mould and pests, resin density and the aromatic profile exactly as the female does; it just expresses several of those traits less visibly since it never grows a smokable 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 line borrows and cannot repeat. Feminizing a female gives pollen; it does not provide a different line of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is built from S1 seeds: a single popular clone, treated and crossed with itself. Every generation of that selfing halves the surviving genetic variation, and after two rounds what is left is close to one plant expressed in marginally different forms.
This is fine for a grower who wants that single plant. It is a loss for everyone who comes after. Hidden weaknesses surface: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Qualities that were present in the original line but absent in the selected clone vanish from the gene pool entirely. A generation of such breeding produces a market crowded with variations of a dozen plants, and a breeder trying to create something new discovers there is nothing left to work with. Regular seed from a true outcrossed line is the store that refills the market, and it only exists as long as people keep growing it.
Reading a Male Plant
Guides on choosing females are easy to find; advice on picking males is scarce, since most growers do not keep one past the first week of flower to judge. For anyone making seed, these are the signs breeders watch for.
- Timing. A male that shows sex early and matures at the same pace as the females is more workable than a very early one that sheds pollen before the female is ready.
- Restraint. Plants that dump enormous quantities of pollen early are often the less selected genetically; breeders favour steady producers.
- Stability. A male that at the same time shows female pistils under normal conditions is rejected outright; that tendency is the one thing anyone wants breeding into a line.
- Structure. Short internodes, a thick main stem and branching that matches the desired female shape are inherited; a lanky, floppy male hands that down too.
What 10 Seeds Actually Give You
The mistake 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 slice of a population, and the value of growing it is to see the range and select from it.
Roughly half the plants will be male, so a pack of 10 seeds yields something like five females to compare and five males to either cull or assess for breeding. Within the females, look for real differences: stature, flowering time, smell, bud structure, resistance. This variation is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male now owns something a feminized pack cannot supply: a line of selected parents which are their own.
Making Your Own Seed
Owning selected parents means producing the next batch, and here the choices multiply. The main methods account for most of what small-scale breeders do.
- Open pollination. Let every male reach every female. It keeps the whole range of the line, makes a large quantity of seed, and involves no selection at all. This is how landrace lines are maintained alive, and it is the right approach when the goal is preservation not improvement.
- Backcross. Take a selected offspring back to one of its parents to lock in a particular quality. It tightens the genetics quickly and is used when a single plant has something worth concentrating and the other contributed mostly vigour.
- Selected cross. One picked male to one or several picked females, everything else culled. The offspring inherit the qualities of the two selected plants and express narrower spread than the parent pack. Repeated over several rounds with stable selection, this is how a new line is made.
Each of these require nothing more than a separate space for the male, a paintbrush or a paper bag, and patience. None of them calls for the chemical reversal that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines have never feminized and likely never will be: landraces collected from regions where cannabis grew for centuries, and old hybrids from the early decades of indoor breeding. They are sold as regular seed because the people maintaining them treat diversity as the entire point, and reversing a single plant would erase 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. There will be wide variation, extended flowering periods in tropical lines, lanky plants, and traits that made sense in a mountain valley but not under a tent. Expect too flavours and chemistry that do not exist in the commercial market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its origin of origin and the generation it has been grown out from the first collection.
The Honest Exclusions
Nothing of the above turns regular seed the best option for everyone, and claiming otherwise does the product no favours.
A grower with space for three plants who needs each one of them to flower is better off with feminized seed. The same is a grower who cannot afford to check the plants each day around the onset of flower, because a missed male in a small space ruins everything within days. Someone growing a single autoflower on a balcony gets no use from a pack they cannot choose from. And a buyer who wants a known famous cut 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 hold onto and at some point to make something of their own; for anyone else the regular shelf is best left alone.
Practicalities
Breeder Regular Seeds dispatches each order in plain parcels with the breeder’s packs intact inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law varies widely by country: in a good number of places buying seeds is legal as genetic preservation while germinating them is not, and in others the two are permitted under licence or both is. Checking the position where you live is the buyer’s job, and nothing of this article should be read as legal advice.
