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 next to it, and bought by a shrinking number of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the bookshop next door grows. Every female-only line started as a regular one, each new cross requires a male somewhere in its history, and the breadth of cannabis genetics that survives at all exists because someone kept regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article makes the case for that unfashionable pack: what the male is for, what a grower loses by never seeing one, and how to work with a population rather than a copy.

Not Just Pollen

The lazy account of a male cannabis plant is “a pollen source”, and to a flower grower that is all it. To a breeder it is half the genome of every seed that follows, and half is selected with the same care as the mother.

A male contributes growth habit, hybrid vigour, maturation time, resistance to mould and pests, resin density and the aromatic chemistry exactly as the female does; it simply expresses several of those qualities less because it does not produce a smokable flower. Those who breed with regular seed invest as much time selecting males as females, and this is the effort that a feminized cross borrows and can never replicate. Reversing a female yields pollen; it does not give a different set of selected genes.

What Happens When Lines Are Only Selfed

Much of the feminized market is made from S1 seeds: a one popular clone, reversed and crossed with itself. Each round of that process cuts in half the remaining genetic diversity, and after two rounds what is left is close to one plant repeated in slightly different forms.

This is fine for a consumer who needs that one plant. It is a loss for everyone downstream. Hidden weaknesses surface: hermaphrodite tendencies, brittle stems, sensitivity to one particular mould. Traits that existed in the parent line but absent in the chosen clone disappear out of the population altogether. A decade of such breeding produces a market full with versions of a dozen plants, and a breeder wanting to create something new finds there is nothing left to cross. Regular seed from a true outcrossed line is the reservoir that refills the market, and that reservoir only exists if people grows it.

Reading a Male Plant

Articles on selecting females are everywhere; advice on picking males is rare, because most people never keep one long enough to judge. For a grower making seed, these are the marks breeders look for.

  • Stability. Any male that also shows female flowers under ordinary conditions is discarded without exception; the trait is the one thing worth breeding into a line.
  • Structure. Short internodes, a strong central stem and branching that matches the intended female habit are passed on; a lanky, weak-stemmed male hands that on too.
  • Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with resin on its flower parts and a strong aroma indicates it holds the terpene traits that are worth keeping.
  • Restraint. Plants that release huge amounts of pollen early are frequently the less desirable genetically; breeders prefer moderate producers.
  • Timing. A male that declares sex early and matures in step with the females is more useful than an early one that releases pollen before any female is receptive.

What 10 Seeds Actually Give You

The mistake new regular-seed buyers fall into is seeing a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the point of growing it is to see the spread and choose from it.

About half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to either discard or judge for breeding. Within the females, look for noticeable differences: stature, finishing time, aroma, density, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. 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 their own.

From One Pack to the Next

Owning chosen parents means producing the next batch, and there the options open up. Three approaches cover most of what home breeders attempt.

  • Backcross. Take a selected seedling again to one of its parents to fix a specific quality. It narrows the genetics fast and is used when one parent has something worth concentrating and the second brought mostly vigour.
  • Selected cross. One chosen male on one or several picked females, everything else culled. The seeds inherit the traits of the two selected plants and show less spread than the original pack. Repeated over several rounds with stable selection, this is how a stable line is built.
  • Open pollination. Let every male reach each female. It keeps the whole range of the line, makes a generous quantity of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the right method when the aim is preservation not improvement.

Each of these need nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. Not one of them needs the chemical reversal that feminized seed-making does.

Keeping Old Lines Alive

Some lines have never feminized and probably never will be: landraces collected from places where cannabis was grown over centuries, and heirloom hybrids from the early decades of indoor breeding. They are available as regular seed since the people maintaining them treat the population as the entire value, and selfing a single plant would erase exactly what makes the line worth the trouble of preserving.

Running a landrace from regular seed is a different experience from growing a modern hybrid. There will be large variation, extended flowering periods in tropical lines, tall plants, and qualities that make sense in a mountain valley but not in a small room. Expect too flavours and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line marked with its origin of origin and the generation it has been reproduced since the original collection.

Who Should Not Buy Regular Seeds

None of the above makes regular seed into the best choice for everyone, and claiming that it is does the product no service.

A grower with space for a handful of plants who needs every one of them to flower is better served with feminized seed. So is anyone unable to inspect the plants every day during the onset of flower, since a late male in a confined space seeds everything inside days. Someone running a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who wants a specific clone-only cut repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to hold onto and eventually to make something new; for anyone else the back shelf is best left where it is.

Ordering and the Law

Breeder Regular Seeds dispatches every order in plain packaging with the breeder’s packs sealed inside and no on the exterior 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 owning seeds is lawful as collectables while germinating them is not, and in others the two are allowed under local rules or both is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article is legal advice.
