Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced lower than the feminized packs next to it, and bought by a dwindling number of people who understand exactly what they are after. It is easy to read that as the end of a technology. It is closer to the truth to see it as a library shrinking while the bookshop next door expands. Every female-only line began as a regular one, each new cross needs a male at some point in its history, and the diversity of cannabis genetics that exists at all exists because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article makes the argument for that half-male pack: what the male contributes, what a buyer loses by never seeing one, and how to get value with a population rather than a clone.
What a Male Plant Is Actually For
The easy 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 that follows, and that half is chosen with the same attention as the female.
A male contributes structure, vigour, maturation speed, tolerance to mould and pests, resin density and the terpene profile exactly as the female does; it just shows some of those qualities less visibly since it does not grows a smokable flower. Those who breed with regular seed invest as much time choosing males as females, which is the effort that a feminized cross borrows and cannot repeat. Reversing a female yields pollen; it does not give a second line of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one famous clone, reversed and crossed with itself. Each generation of that selfing halves the surviving genetic diversity, and after two generations what is left is close to one plant expressed in slightly different forms.
That is acceptable for a consumer who needs that single plant. It is a loss for everyone downstream. Recessive weaknesses surface: intersex tendencies, brittle stems, susceptibility to a particular mould. Qualities that existed in the parent line but absent in the chosen clone disappear from the population altogether. A generation of this produces a market full with variations of the same few clones, and a breeder wanting to create something new finds there is little left to cross. Regular seed from a true outcrossed line is the store that replenishes the market, and it can only exists if people grows it.
Reading a Male Plant
Articles on choosing females are easy to find; advice on choosing males is rare, since most people never keep one long enough to look. For anyone making seed, the following are the signs breeders watch for.
- Structure. Tight internodes, a strong main stem and branching that matches the desired female shape are inherited; a stretched, weak-stemmed male hands that on too.
- Timing. A male that shows sex early and flowers in step with the females is far more useful than a very early one that releases pollen before any female is ready.
- Stability. A male that also forms female pistils under ordinary stress is discarded outright; that tendency is the last thing anyone wants carrying into a line.
- Restraint. Plants that dump enormous quantities of pollen early are often also the less selected in other respects; breeders prefer steady shedders.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with resin on its flower parts and a strong aroma suggests it holds the resin traits worth keeping.
A Pack Is a Population
The error first-time regular-seed buyers make is treating 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 growing it is to observe the range and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields around five females to compare and five males to either discard or assess for breeding. Among the females, expect noticeable differences: stature, finishing time, aroma, 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 the best male now owns something a feminized pack cannot offer: a pair of chosen parents which are theirs.
Making Your Own Seed
Owning chosen parents is only worth something if making the next batch, and here the options multiply. Three methods account for most of what small-scale breeders attempt.
- Selected cross. One chosen male to one or several chosen females, everything else culled. The seeds carry the traits of the two specific plants and express less spread than the parent pack. Done over several rounds with stable selection, this is how a new line is made.
- Open pollination. Let each male reach each female. It keeps the full range of the line, produces a large quantity of seed, and involves no selection at all. This is how traditional lines are kept alive, and it is the correct approach when the aim is preservation not refinement.
- Backcross. Cross a chosen seedling back to one of its original parents to lock in a particular trait. It tightens the range quickly and is useful when one plant shows something worth concentrating and the second contributed mainly vigour.
Each of these require only a isolated space for the male, a soft brush or a paper bag, and a few weeks. None of them needs the chemical treatment 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 regions where cannabis grew over centuries, and old crosses from the first decades of indoor breeding. They are available as regular seed because the breeders keeping them regard diversity as the whole value, and selfing a single plant would destroy exactly 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 times in tropical lines, lanky plants, and traits that made sense in a mountain valley but not under a tent. There will be also flavours and effects that no longer exist in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its region of collection and the generation it has been grown out since the original collection.
Who Should Not Buy Regular Seeds
None of the above turns regular seed into the right choice for everyone, and claiming otherwise would the product no service.
A grower with room for three plants who wants each one of them to flower is far better off with feminized seed. The same is anyone unable to inspect the plants each day around the start of flower, because a late male in a small space ruins everything inside days. A person growing a single autoflower on a balcony gets no value from a pack they cannot select from. And a buyer who wants a known famous cut reproduced exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to choose, to keep and eventually to make something new; for anyone else the regular shelf is best ignored where it is.
Practicalities
Breeder Regular Seeds dispatches every order in unmarked parcels with the breeder’s packs sealed inside and nothing on the outside to indicate 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 buying seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under licence or both is. Knowing the rules in your own jurisdiction is the buyer’s job, and nothing of this article is legal advice.
