What Disappears When Every Seed Is Female

Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced lower than the feminized packs next to it, and bought by a dwindling number of people who know exactly what they are after. It is tempting to see that as the end of a technology. It is closer to the truth to see it as a library losing shelves while the bookshop next door grows. Every female-only line began as a regular one, each new cross requires a male at some point in its history, and the breadth of cannabis genetics that survives at all exists only because someone kept regular seed. Dedicated sellers 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 argument for that unfashionable pack: what the male contributes, what a buyer gives up by not seeing one, and how to get value with a pack rather than a copy.

The Other Half of the Genome

The easy account of a male cannabis plant is «the one that makes pollen», and for a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and half is selected with the same attention as the female.

A male passes on structure, hybrid vigour, maturation speed, resistance to mould and pests, trichome production and the aromatic profile just as the female does; it simply shows several of those qualities less visibly since it never grows a smokable flower. Breeders who breed with regular seed invest as much time choosing males as females, which is the effort that a feminized cross inherits and cannot replicate. Feminizing a female gives pollen; it cannot provide a different line of selected genes.

What Happens When Lines Are Only Selfed

Much of the feminized catalogue is built from S1 seeds: a single popular clone, treated and crossed with itself. Each generation of that process halves the remaining genetic diversity, and after a couple of rounds what is left is close to one plant repeated in marginally different ways.

This is fine for a grower who needs that one plant. It is a problem for everyone who comes after. Hidden faults surface: intersex tendencies, brittle stems, susceptibility to one particular mould. Traits that existed in the parent line but absent in the chosen clone vanish from the population altogether. A generation of this leaves a market full with versions of a dozen plants, and a anyone wanting to make something different finds there is nothing remaining to work with. Regular seed from an outcrossed line is the reservoir that replenishes the pool, and it only persist if somebody grows it.

Reading a Male Plant

Guides on selecting females are easy to find; advice on picking males is rare, since most people never keep one past the first week of flower to look. For anyone making seed, the following are the signs breeders watch for.

• Structure. Short internodes, a strong central stem and a frame that matches the desired female habit are passed on; a lanky, 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 scent indicates it carries the terpene traits that are worth passing on.
• Timing. A male that shows sex early and flowers at the same pace as the females is far more useful than an early one that releases pollen before any female is receptive.
• Stability. A male that also shows female flowers under normal stress is rejected outright; that trait is the last thing worth carrying forward.

Thinking in Numbers

A mistake new regular-seed growers make is seeing a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the value of growing it is to observe the spread and select from it.

Roughly half the plants will be male, which means a pack of 10 seeds yields something like five females to evaluate and five males to either cull or assess for breeding. Among the females, look for real differences: stature, flowering time, aroma, bud structure, resistance. That variation 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 cannot supply: a pair of selected parents which are their own.

Making Your Own Seed

Holding chosen parents means producing the next batch, and here the choices open up. Three approaches cover most of what home breeders do.

• Backcross. Cross a chosen offspring back to one of its original parents to lock in a particular trait. It narrows the range quickly and is useful when one plant has something worth concentrating and the second brought mostly vigour.
• Open pollination. Allow every male reach each female. It preserves the full range of the line, makes a generous volume of seed, and does no choosing at all. This is how landrace lines are kept alive, and it is the correct method when the goal is preservation rather than improvement.
• Selected cross. One chosen male to one or a few picked females, every other plant else culled. The offspring inherit the traits of two specific plants and express less spread than the original pack. Done over generations with consistent choices, this is how a stable line is built.

All three require nothing more than a separate space for the male, a soft brush or a paper bag, and patience. Not one of them calls for the chemical treatment that feminized production requires.

The Seeds That Only Exist as Regulars

A number of lines were never been feminized and likely never will be: landraces collected from regions where cannabis grew for centuries, and heirloom hybrids from the early decades of modern breeding. They are sold as regular seed because the breeders maintaining them treat diversity as the whole point, and selfing a single clone would destroy precisely what makes the line worth preserving.

Running a landrace from regular seed is different from growing a commercial hybrid. There will be wide variation, extended flowering times in tropical lines, tall plants, and traits that made sense in a field but not under a tent. Expect also aromas and chemistry that no longer exist in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, with each line marked with its region of origin and the number of generations it has been grown out since the first collection.

When the Library Is the Wrong Shop

None of the above makes regular seed into the right option for everyone, and pretending that it is does the category no service.

A grower with space for three plants who needs each one of them to finish is better served with feminized seed. So is a grower who cannot afford to check the plants each day around the onset of flower, since a missed male in a small space ruins the whole crop inside days. A person growing a single autoflower on a balcony has no use from a population they cannot choose from. And anyone who wants a known clone-only cut repeated as closely as possible is better off 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 make something new; for anyone else the regular shelf is safely ignored alone.

Ordering and the Law

Breeder Regular Seeds sends each order in plain packaging with the breeder’s packs intact inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law differs widely by country: in many places buying seeds is legal as genetic preservation while germinating them is not, and in others both are allowed under licence or both is. Checking the rules where you live is the buyer’s job, and no part of this article is legal advice.
