Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, priced cheaper than the feminized packs next to it, and picked up by a dwindling 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 read it as a library losing shelves while the bookshop next door expands. Every feminized line began as a regular one, each new cross requires a male at some point in its history, and the breadth of cannabis genetics that survives at all exists only because someone kept regular seed. Specialists such as https://breederregularseeds.com carry lines that trace 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 half-male pack: what the male contributes, what a grower loses by not seeing one, and how to work with a pack instead of a copy.
Not Just Pollen
The easy account of a male cannabis plant is “a pollen source”, 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 female.
A male contributes growth habit, vigour, flowering time, resistance to mould and pests, trichome production and the terpene profile exactly as the female does; it simply shows some of those traits less visibly because it never grows a smokable flower. Those who work with regular seed spend as much time selecting males as females, and this is the effort that a feminized cross inherits and cannot replicate. Feminizing a female gives pollen; it does not give a different set of selected traits.
How Diversity Leaks Away
Much of the feminized catalogue is made from S1 seeds: a single popular clone, treated and pollinated with itself. Every generation of that process halves the surviving genetic variation, and after a couple of rounds what remains is close to one plant expressed in slightly different forms.
This is acceptable for a consumer who needs that one plant. It is a problem for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, brittle stems, susceptibility to one particular mould. Qualities that were present in the parent line but absent in the chosen clone disappear out of the gene pool entirely. A decade of such breeding leaves a market full with variations of the same few plants, and a breeder trying to create something new finds there is little remaining to cross. Regular seed from an outcrossed line is the store that refills the market, and that reservoir can only persist if somebody grows it.
How to Judge a Male
Articles on choosing females are easy to find; advice on choosing males is scarce, since most growers do not keep one long enough to judge. For anyone making seed, the following are the marks breeders watch for.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a clear aroma indicates it holds the terpene genes that are worth passing on.
- Stability. Any male that also forms female flowers under normal conditions is discarded outright; that trait is the one thing anyone wants breeding forward.
- Restraint. Males that dump huge amounts of pollen early are often the least desirable genetically; breeders favour steady shedders.
- Timing. A male that shows sex early and matures in step with the females is far more workable than a very early one that sheds pollen before the female is ready.
What 10 Seeds Actually Give You
A mistake new regular-seed buyers make is treating a pack as 10 attempts 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 observe the spread and select from it.
About half the plants will be male, which means a pack of 10 seeds yields something like five females to evaluate and five males to either discard or assess for breeding. Within the females, look for noticeable variation: stature, finishing time, smell, bud structure, tolerance. That variation is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and male now owns something a feminized pack cannot offer: a pair of selected parents that are theirs.
From One Pack to the Next
Owning chosen parents means making the next generation, and here the choices open up. Three methods cover most of what small-scale breeders do.
- Open pollination. Let every male pollinate each female. It keeps the whole range of the line, produces a generous volume of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the correct approach when the aim is preservation rather than improvement.
- Backcross. Cross a chosen seedling back to one of its original parents to lock in a particular trait. It narrows the range quickly and is used when one plant shows something worth keeping and the second brought mostly vigour.
- Selected cross. One chosen male on one or several chosen females, every other plant else culled. The offspring inherit the traits of the two selected plants and show less spread than the original pack. Repeated over generations with stable choices, this is how a stable line is built.
All three require only a separate space for the male, a soft brush or a small bag, and patience. Not one of them needs the chemical treatment that feminized production does.
Landraces and Heirloom Lines
Some lines have never feminized and likely never will be: landraces collected from places where cannabis grew over centuries, and heirloom crosses from the early decades of indoor breeding. They are sold as regular seed since the people keeping them treat diversity as the whole value, and selfing a single plant would erase exactly what makes the line worth the trouble of preserving.
Running a landrace from regular seed is different from running a modern hybrid. There will be wide variation, long flowering periods in tropical lines, tall plants, and traits that made sense in a mountain valley but not in a tent. There will be also aromas and chemistry that do not appear in the commercial market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its region of origin and the number of generations it has been reproduced from the original collection.
When the Library Is the Wrong Shop
None of the above makes regular seed the right choice for everyone, and pretending that it is would the category no service.
A grower with room for a handful of plants who needs each one of them to flower is better off with feminized seed. The same is anyone who cannot afford to inspect the plants each day around the start of flower, because a late male in a small space seeds the whole crop inside days. Someone running a single autoflower on a balcony has no value from a population they cannot choose from. And a buyer who is after a known clone-only cut repeated as closely as possible is 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 make something new; for everyone else the back shelf is safely ignored where it is.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked parcels with the breeder’s packs sealed inside and no on the outside to reveal the contents. Orders to the United States are not accepted, as seed import is restricted there. Seed law differs widely by country: in many places owning seeds is lawful as genetic preservation while germinating them is not, and in others both are allowed under local rules or neither is. Checking the rules where you live is the buyer’s job, and nothing of this article should be read as legal advice.
