The Case for the Male Plant
Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are after. It is easy to see that as obsolescence. It is nearer to the truth to see it as a library shrinking while the bookshop next door grows. Every female-only line started as a regular one, each new cross needs a male somewhere in its history, and the breadth of cannabis genetics that exists at all survives only because somebody kept regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a single plant. This article makes the argument for that unfashionable pack: what the male is for, what a grower gives up by never growing one, and how to work with a population instead of a copy.
Not Just Pollen
The easy account of a male cannabis plant is "a pollen source", and for a flower grower that is all it. To a breeder it is half the genome of every seed which follows, and half is selected with the same care as the female.
A male contributes growth habit, hybrid vigour, flowering speed, resistance to mould and pests, trichome production and the aromatic chemistry just as the female does; it just expresses some of those qualities less visibly since it does not produce a smokable flower. Breeders who breed with regular seed invest at least as much time choosing males as females, and this is the work that a feminized cross borrows and can never replicate. Feminizing a female yields pollen; it does not give a second set of selected traits.
The Narrowing
A great deal of the feminized catalogue is built from S1 seeds: a one famous clone, reversed and pollinated with itself. Every round of that selfing cuts in half the remaining genetic variation, and after a couple of rounds what remains is close to one plant repeated across slightly different ways.
This is fine for a consumer who needs that one plant. It is a loss for everyone downstream. Recessive faults surface: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Qualities that existed in the original line but absent in the chosen clone disappear out of the population entirely. A decade of this produces a market full with versions of a dozen plants, and a breeder trying to make something different finds there is little left to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and it only exists as long as people keep growing it.
Selecting the Plant Nobody Writes About
Articles on selecting females are everywhere; guidance on choosing males is rare, because most growers do not keep one long enough to judge. For a grower producing seed, the following are the marks breeders watch for.
- Structure. Short internodes, a thick central stem and a frame that matches the intended female habit are passed on; a lanky, weak-stemmed male passes that down too.
- Stability. A male that also shows female pistils under normal conditions is rejected outright; the trait is the last thing worth breeding forward.
- Timing. A male that declares sex first and matures in step with the females is far more workable than an early one that sheds pollen before any female is receptive.
- Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with trichomes on its sepals and a strong aroma suggests it carries the terpene genes worth passing on.
- Restraint. Plants that dump enormous quantities of pollen all at once are often also the least selected in other respects; breeders favour steady producers.
Thinking in Numbers
The error first-time regular-seed buyers fall into is treating a pack as 10 attempts at the one plant. It is the opposite. 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, which means a pack of 10 seeds yields around five females to compare and five males to either discard or assess for breeding. Within the females, look for real variation: stature, flowering time, smell, bud structure, tolerance. This 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 now owns something a feminized pack can never offer: a line of chosen parents that are theirs.
Three Ways to Cross
Owning selected parents means producing the next batch, and there the choices multiply. The main approaches account for most of what home breeders do.
- Open pollination. Allow each male reach each female. It keeps the whole diversity of the line, produces a large quantity of seed, and does no choosing at all. This is how landrace lines are maintained alive, and it is the right method when the aim is preservation rather than refinement.
- 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 variation than the parent pack. Done over generations with consistent selection, this is how a stable line is made.
- Backcross. Cross a chosen seedling again to one of its parents to fix a specific quality. It tightens the genetics quickly and is useful when a single plant shows something worth keeping and the other brought mainly vigour.
All three need nothing more than a separate space for the male, a paintbrush or a small bag, and patience. None of them calls for the chemical treatment that feminized production does.
The Seeds That Only Exist as Regulars
Some lines were 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 modern breeding. They are sold as regular seed because the breeders keeping them treat the population as the entire point, and reversing a single clone would erase exactly what makes the line worth keeping.
Growing a landrace from regular seed is a different experience from running a modern hybrid. There will be wide variation, long flowering periods in tropical lines, lanky plants, and traits that made sense in a field but not under a small room. There will be too aromas and effects that no longer appear in the commercial market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line marked with its region of origin and the generation it has been grown out since the first collection.
Who Should Not Buy Regular Seeds
Nothing of the above makes regular seed the best option for everyone, and claiming that it is does the product no favours.
A grower with space for three plants who needs every one of them to flower is better served with feminized seed. So is anyone who cannot afford to inspect the plants every day during the onset of flower, since a missed male in a confined space seeds everything within days. A person running a single autoflower on a balcony has no value from a population they cannot select from. And a buyer who wants a specific famous plant reproduced exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to keep and at some point to produce something new; for anyone else the regular shelf is best ignored where it is.
Practicalities
Breeder Regular Seeds dispatches each order in plain packaging with the breeder's packs intact inside and nothing on the outside to reveal the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law differs sharply by country: in a good number of places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are allowed under local rules or neither is. Knowing the rules where you live is the buyer's job, and no part of this article is legal advice.
