Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower than the feminized packs beside it, and picked up by a shrinking number of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is closer to the truth to see it as a library losing shelves while the bookshop next door expands. Every female-only line began as a regular one, every new cross needs 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 stock lines that trace to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article makes the argument for that unfashionable pack: what the male contributes, what a grower gives up by not growing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The lazy account of a male cannabis plant is “a pollen source”, and to 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 chosen with the same attention as the female.
A male contributes structure, vigour, maturation time, tolerance to mould and pests, trichome production and the aromatic profile just as the female does; it just shows some of those traits less visibly since it never produce a smokable flower. Breeders who work with regular seed invest as much time choosing males as females, which is the work that a feminized cross borrows and cannot replicate. Feminizing a female yields pollen; it does not provide a second line of selected genes.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a one popular clone, treated and crossed with itself. Every round of that process cuts in half the surviving genetic variation, and after two rounds what remains is essentially one plant expressed across marginally different ways.
That is acceptable for a consumer who needs that single plant. It is a problem for everyone downstream. Hidden weaknesses emerge: intersex tendencies, weak stems, susceptibility to a particular mould. Traits that were present in the parent line but absent in the chosen clone disappear out of the population entirely. A generation of such breeding produces a market full with versions of the same few clones, and a anyone wanting to create something new finds there is nothing left to work with. Regular seed from an outcrossed line is the reservoir that replenishes the market, and it can only exists as long as somebody keep growing it.
Reading a Male Plant
Articles on selecting females are everywhere; advice on picking males is rare, because most people never keep one past the first week of flower to look. For anyone producing seed, the following are the marks breeders look for.
- Structure. Tight internodes, a strong main stem and branching that resembles the desired female habit are passed on; a lanky, floppy male hands that on too.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its flower parts and a strong scent indicates it holds the resin traits that are worth passing on.
- Stability. Any male that also forms female flowers under normal stress is rejected without exception; the trait is the one thing worth breeding into a line.
- Timing. A male that declares sex first and flowers in step with the females is far more workable than an early one that releases pollen before any female is receptive.
- Restraint. Males that release enormous quantities of pollen early are frequently also the least selected genetically; many breeders prefer moderate shedders.
A Pack Is a Population
The mistake new regular-seed buyers fall into is treating a pack as 10 chances at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the value of growing it is to see the spread and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds gives something like five females to compare and five males to cull or judge for breeding. Within the females, look for real differences: height, finishing time, smell, bud structure, tolerance. This spread is not a failure in the seed; it is what the seed is selling. The grower who keeps the best female and male now owns something a feminized pack can never supply: a line of selected parents that are their own.
Three Ways to Cross
Holding selected parents is only worth something if making the next generation, and there the options multiply. Three approaches account for most of what home breeders do.
- Selected cross. One picked male on one or a few picked females, every other plant else culled. The offspring carry the qualities of two selected plants and express narrower variation than the parent pack. Done over several rounds with stable choices, this is how a new line is built.
- Backcross. Take a selected seedling back to one of its parents to lock in a specific quality. It tightens the genetics fast and is used when a single parent shows something worth keeping and the other contributed mostly vigour.
- Open pollination. Let each male reach every female. It preserves the full diversity of the line, makes a generous quantity of seed, and involves no choosing at all. This is how traditional lines are kept going, and it is the correct method when the aim is preservation not refinement.
All three require only a isolated space for the male, a soft brush or a paper bag, and a few weeks. Not one of them calls for the chemical reversal that feminized seed-making does.
Keeping Old Lines Alive
Some lines were never feminized and likely never will be: landraces gathered from regions where cannabis grew for centuries, and old crosses from the early decades of modern breeding. They are available as regular seed since the people keeping them treat diversity as the whole point, and reversing a single clone would erase precisely what makes the line worth preserving.
Running a landrace from regular seed is a different experience from running a commercial hybrid. Expect large variation, extended flowering periods in tropical lines, tall plants, and traits that made sense in a field but not in a small room. Expect too aromas and effects that do not appear in the commercial market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line marked with its region of origin and the generation it has been grown out from the first collection.
When the Library Is the Wrong Shop
None of the above turns regular seed into the best choice for everyone, and claiming otherwise does the category no favours.
A grower with space for three plants who needs each one of them to finish is far better served with feminized seed. The same is a grower who cannot afford to inspect the plants every day during the start of flower, since a missed male in a confined space ruins everything inside days. Someone growing a single autoflower on a balcony gets no value from a population they cannot choose from. And a buyer who wants a known famous plant repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to hold onto and eventually to produce something new; for anyone else the regular shelf is safely left where it is.
Before You Buy
Breeder Regular Seeds sends every order in plain packaging with the original packs sealed inside and nothing on the outside to indicate the contents. Orders to the United States are not taken, as seed importation is not permitted there. Seed law differs widely by country: in many places owning seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or both is. Checking the position where you live is the buyer’s job, and no part of this article is legal advice.
