Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, priced lower than the feminized packs beside it, and picked up by a dwindling group of people who know exactly what they are looking for. It is easy to see that as the end of a technology. It is nearer to the truth to read it as a library shrinking while the paperback rack next door expands. Every feminized line started as a regular one, every new cross requires a male somewhere in its history, and the diversity of cannabis genetics that exists at all survives 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 unfashionable pack: what the male contributes, what a grower loses by never seeing one, and how to get value with a population rather than a copy.
Not Just Pollen
The easy description of a male cannabis plant is “a pollen source”, and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed that follows, and that half is chosen with the same attention as the female.
A male passes on growth habit, hybrid vigour, maturation speed, resistance to mould and pests, trichome density and the aromatic profile just as the female does; it simply expresses some of those traits less visibly since it does not produce a smokable flower. Those who work with regular seed spend as much time choosing males as females, which is the work that a feminized cross borrows and can never repeat. Feminizing a female gives pollen; it does not give a different line of selected traits.
How Diversity Leaks Away
Much of the feminized market is built from S1 seeds: a one popular clone, treated and crossed with itself. Each generation of that process cuts in half the remaining genetic variation, and after a couple of rounds what remains is close to one plant expressed across marginally different ways.
This is acceptable for a consumer who wants that single plant. It is a loss for everyone who comes after. Hidden weaknesses emerge: intersex tendencies, brittle stems, susceptibility to a particular mould. Qualities that existed in the original line but not in the selected clone vanish from the gene pool altogether. A decade of such breeding leaves a market crowded with versions of a dozen clones, and a anyone wanting to make something new discovers there is little left to work with. Regular seed from an outcrossed line is the store that replenishes the pool, and it can only exists if people grows it.
Selecting the Plant Nobody Writes About
Articles on choosing females are easy to find; guidance on choosing males is rare, because most people do not keep one long enough to look. For a grower producing seed, these are the signs breeders watch for.
- Restraint. Plants that dump huge amounts of pollen early are frequently the least selected in other respects; breeders favour moderate producers.
- Stability. A male that at the same time forms female pistils under normal conditions is rejected outright; the tendency is the last thing anyone wants breeding into a line.
- Timing. A male that declares sex early and matures in step with the females is far more useful than an early one that sheds pollen before the female is ready.
- Structure. Tight internodes, a strong central stem and a frame that resembles the desired female shape are passed on; a stretched, floppy male hands that down too.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with resin on its sepals and a strong aroma indicates it holds the terpene genes worth passing on.
Thinking in Numbers
The error new regular-seed buyers make is seeing a pack as 10 attempts at the one plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the value of running it is to observe the range and select from it.
About half the plants will be male, which means a pack of 10 seeds gives something like five females to evaluate and five males to cull or judge for breeding. Among the females, look for real variation: stature, flowering time, smell, density, tolerance. That spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male has something a feminized pack can never supply: a pair of selected parents that are theirs.
From One Pack to the Next
Holding chosen parents means making the next generation, and here the choices multiply. Three approaches cover most of what small-scale breeders attempt.
- Backcross. Cross a chosen offspring back to one of its parents to fix a particular trait. It tightens the range fast and is useful when a single parent has something worth concentrating and the other brought mostly vigour.
- Open pollination. Allow each male pollinate every female. It keeps the full range of the line, produces a generous volume of seed, and does no selection at all. This is how traditional lines are maintained going, and it is the right approach when the aim is preservation not improvement.
- Selected cross. One chosen male to one or a few chosen females, everything else culled. The offspring inherit the traits of the two selected plants and express narrower spread than the original pack. Done over generations with stable selection, this is how a new line is built.
Each of these need nothing more than a separate space for the male, a paintbrush or a paper bag, and a few weeks. None of them needs the chemical treatment that feminized production requires.
The Seeds That Only Exist as Regulars
A number of lines were never feminized and likely never will be: landraces gathered from places where cannabis grew for centuries, and heirloom hybrids from the first decades of indoor breeding. They are available as regular seed since the breeders keeping them regard the population as the whole point, and selfing a single clone would erase precisely what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is different from running a commercial hybrid. Expect large variation, long flowering times in tropical lines, lanky plants, and traits that made sense in a field but not under a small room. Expect too aromas and effects that no longer exist in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of origin and the number of generations it has been reproduced from the first collection.
When the Library Is the Wrong Shop
Nothing of the above makes regular seed into the best option for everyone, and claiming that it is would the category no service.
A grower with space for a handful of plants who needs each one of them to finish is better off with feminized seed. So is anyone who cannot afford to check the plants every day during the start of flower, since a late male in a small space ruins the whole crop inside days. A person growing a single autoflower on a balcony has no value from a pack they cannot choose from. And anyone who wants a known famous cut reproduced exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to keep and eventually to produce something new; for everyone else the back shelf is safely left alone.
Before You Buy
Breeder Regular Seeds dispatches every order in unmarked parcels with the breeder’s packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed importation is not permitted there. Seed law varies sharply by country: in many places owning seeds is legal as collectables while germinating them is not, and in others the two are permitted under local rules or both is. Knowing the rules where you live is the buyer’s responsibility, and nothing of this article should be read as legal advice.
