Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, priced lower than the feminized packs next to it, and bought by a dwindling group 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 read it as a library shrinking while the bookshop next door expands. Every feminized line began as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all survives because somebody held onto regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article sets out the case for that unfashionable pack: what the male contributes, what a buyer loses by never seeing one, and how to get value with a population instead of a copy.
What a Male Plant Is Actually For
The easy description of a male cannabis plant is «the one that makes pollen», and to a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and half is chosen with the same attention as the mother.
A male passes on structure, vigour, flowering time, tolerance to mould and pests, resin density and the aromatic chemistry just as the female does; it simply shows several of those qualities less because it never grows a smokable flower. Those who breed with regular seed spend at least as much time choosing males as females, which is the effort that a feminized line inherits and can never replicate. Feminizing a female yields pollen; it does not give a different line of selected genes.
How Diversity Leaks Away
A great deal of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and crossed with itself. Every generation of that process halves the remaining genetic variation, and after two generations what is left is essentially one plant expressed across marginally different ways.
That is acceptable for a consumer who needs that one plant. It is a problem for everyone who comes after. Recessive faults emerge: intersex tendencies, brittle stems, susceptibility to one particular mould. Traits that existed in the original line but absent in the chosen clone vanish out of the population entirely. A decade of this leaves a market full with variations of a dozen plants, and a breeder wanting to create something new discovers there is nothing remaining to work with. Regular seed from an outcrossed line is the store that replenishes the pool, and it only persist if people grows it.
Selecting the Plant Nobody Writes About
Guides on selecting females are easy to find; advice on picking males is rare, since most people do not keep one long enough to look. For a grower making seed, these are the marks breeders look for.
- Timing. A male that shows sex first and flowers in step with the females is far more useful than an early one that releases pollen before any female is ready.
- Restraint. Plants that dump huge amounts of pollen all at once are often the less selected genetically; many breeders favour moderate shedders.
- Stability. A male that at the same time forms female flowers under normal conditions is discarded without exception; that tendency is the one thing anyone wants carrying into a line.
- Structure. Tight internodes, a strong main stem and branching that matches the desired female shape are inherited; 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 flower parts and a clear aroma suggests it holds the resin traits worth passing on.
Thinking in Numbers
The mistake 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 genuine outcrossed line is a sample of a population, and the point of growing it is to see the range and select from it.
About half the plants will be male, so a pack of 10 seeds gives around five females to compare and five males to either cull or assess for breeding. Among the females, look for noticeable differences: stature, finishing time, aroma, bud structure, tolerance. That variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the best female and male has something a feminized pack can never offer: a pair of selected parents that are their own.
Three Ways to Cross
Owning chosen parents means making the next batch, and there the choices open up. The main methods account for most of what small-scale breeders do.
- Open pollination. Allow every male pollinate each female. It preserves the whole diversity of the line, produces a generous volume of seed, and involves no selection at all. This is how traditional lines are maintained alive, and it is the right method when the aim is preservation not improvement.
- Backcross. Cross a selected offspring again to one of its original parents to lock in a particular trait. It narrows the genetics fast and is useful when one parent shows something worth concentrating and the other contributed mainly vigour.
- Selected cross. One picked male to one or several chosen females, everything else culled. The offspring inherit the qualities of two specific plants and show less variation than the parent pack. Done over generations with stable selection, this is how a stable line is made.
Each of these require only a isolated space for the male, a paintbrush or a paper bag, and patience. None of them calls for the chemical treatment that feminized production requires.
Keeping Old Lines Alive
A number of lines have never feminized and probably never will be: landraces gathered from places where cannabis was grown for centuries, and old hybrids from the first decades of modern breeding. They are sold as regular seed since the people maintaining them treat diversity as the entire value, and reversing a single plant would destroy exactly what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is a different experience from running a commercial hybrid. Expect large variation, long flowering periods in equatorial lines, tall plants, and traits that make sense in a field but not in a tent. There will be too aromas and effects that do not appear in the hybrid market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its region of collection and the generation it has been reproduced from the first collection.
The Honest Exclusions
Nothing of the above makes regular seed the best choice for everyone, and claiming that it is does the product no favours.
A grower with room for three plants who wants every one of them to flower is far better off with feminized seed. The same is anyone who cannot afford to check the plants every day around the onset of flower, because a missed male in a small space seeds everything inside days. A person running a single autoflower on a balcony has no use from a pack they cannot choose from. And a buyer who is after a known famous plant reproduced as closely as possible is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to keep and eventually to make something of their own; for everyone else the regular shelf is safely left where it is.
Practicalities
Breeder Regular Seeds dispatches every order in unmarked packaging with the original packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law varies widely by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others the two are allowed under local rules or both is. Knowing the position where you live is the buyer’s job, and no part of this article should be read as legal advice.
