Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked cheaper than the feminized packs beside 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 closer to the truth to see it as a library shrinking while the bookshop next door expands. Every female-only line started as a regular one, every new cross needs a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives because somebody kept regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article makes the argument for that unfashionable pack: what the male is for, what a grower gives up by never seeing one, and how to get value with a population instead of a clone.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is all it. To a breeder it is half the genome of every seed which follows, and half is selected with the same care as the mother.
A male passes on growth habit, hybrid vigour, maturation speed, resistance to mould and pests, trichome production and the terpene chemistry just as the female does; it just expresses several of those qualities less because it does not grows a smokable flower. Those who work with regular seed spend as much time choosing males as females, and this is the effort that a feminized cross borrows and can never repeat. Reversing a female yields pollen; it does not give a different set of selected traits.
The Narrowing
A great deal of the feminized market is built from S1 seeds: a single popular clone, reversed and pollinated with itself. Every round of that process halves the surviving genetic variation, and after a couple of generations what is left is close to one plant repeated across marginally different forms.
That is fine for a consumer who wants that one plant. It is a loss for everyone who comes after. Hidden weaknesses emerge: intersex tendencies, weak stems, sensitivity to a particular mould. Traits that were present in the original line but not in the chosen clone vanish from the gene pool altogether. A generation of this leaves a market crowded with versions of the same few clones, and a breeder wanting to make something new finds there is nothing remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and that reservoir can only persist as long as somebody keep growing it.
Reading a Male Plant
Guides on selecting females are easy to find; guidance on picking males is scarce, because most people do not keep one long enough to judge. For a grower producing seed, the following are the signs breeders watch for.
- Timing. A male that declares sex early and matures at the same pace as the females is far more useful than an early one that releases pollen before any female is receptive.
- Restraint. Plants that dump huge quantities of pollen all at once are often also the least selected in other respects; breeders prefer moderate shedders.
- Structure. Short internodes, a thick central stem and branching that matches the desired female shape are passed on; a lanky, weak-stemmed male hands that down too.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its sepals and a clear scent indicates it holds the terpene traits that are worth keeping.
- Stability. Any male that at the same time shows female flowers under ordinary conditions is rejected without exception; that tendency is the last thing worth carrying forward.
What 10 Seeds Actually Give You
A error first-time regular-seed growers make is seeing a pack as 10 chances at the one plant. It is the opposite. A pack from a real outcrossed line is a sample of a population, and the value of running it is to observe the range and choose from it.
About half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to either discard or judge for breeding. Within the females, look for real differences: stature, flowering time, smell, density, tolerance. This variation is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and the best male now owns something a feminized pack can never supply: a pair of chosen parents that are their own.
From One Pack to the Next
Owning selected parents is only worth something if making the next generation, and here the choices open up. Three methods cover most of what small-scale breeders do.
- Selected cross. One picked male on one or a few picked females, everything else culled. The seeds carry the traits of two specific plants and express narrower variation than the parent pack. Repeated over generations with consistent choices, this is how a new line is made.
- Backcross. Cross a chosen offspring back to one of its parents to lock in a specific trait. It narrows the range fast and is useful when a single plant has something worth concentrating and the second contributed mostly vigour.
- Open pollination. Let each male pollinate each female. It keeps the whole diversity of the line, makes a generous volume of seed, and does no choosing at all. This is how traditional lines are kept alive, and it is the correct approach when the aim is preservation not improvement.
All three require only a separate space for the male, a soft brush or a paper bag, and patience. Not one of them needs the chemical reversal that feminized production does.
The Seeds That Only Exist as Regulars
A number of lines were never feminized and probably never will be: landraces collected from places where cannabis grew over centuries, and old hybrids from the early decades of modern breeding. They are sold as regular seed since the breeders keeping them treat diversity as the whole point, and reversing a single plant would erase exactly what makes the line worth preserving.
Running a landrace from regular seed is a different experience from running a commercial hybrid. There will be large variation, extended flowering times in equatorial lines, tall plants, and traits that made sense in a field but not in a small room. Expect also flavours and chemistry that do not appear in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line labelled with its origin of collection and the number of generations it has been grown out from the first collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed the right choice for everyone, and pretending that it is would the product no service.
A grower with space for a handful of plants who wants every one of them to finish is far better off with feminized seed. The same is anyone unable to inspect the plants every day around the onset of flower, since a late male in a small space seeds the whole crop within days. A person running a single autoflower on a balcony has no value from a population they cannot choose from. And anyone who is after a specific famous plant repeated as closely as possible is better off 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 back shelf is best ignored where it is.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked packaging with the breeder’s packs intact inside and nothing on the outside to reveal the contents. Orders to the United States are not accepted, because seed importation is not permitted there. Seed law varies sharply by country: in many places buying seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under licence or both is. Checking the position in your own jurisdiction is the buyer’s responsibility, and nothing of this article is legal advice.
