Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, priced cheaper than the feminized packs next to it, and picked up by a dwindling group of people who understand exactly what they are looking for. It is easy to see that as the end of a technology. It is nearer to the truth to see it as a library losing shelves while the paperback rack next door expands. Every female-only line began as a regular one, every new cross needs a male somewhere in its pedigree, and the diversity of cannabis genetics that exists at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article sets out the case for that half-male pack: what the male is for, what a grower loses by not seeing one, and how to get value with a pack instead of a clone.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is „a pollen source“, and for a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and that half is selected with the same attention as the mother.
A male passes on structure, hybrid vigour, maturation time, resistance to mould and pests, trichome density and the terpene profile just as the female does; it simply shows several of those traits less because it does not grows a smokable flower. Breeders who breed with regular seed invest 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 provide a second line of selected traits.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a one popular clone, reversed and crossed with itself. Every round of that selfing halves the surviving genetic diversity, and after two rounds what is left is close to one plant expressed across marginally different ways.
This is acceptable for a consumer who wants that one plant. It is a loss for everyone who comes after. Recessive weaknesses emerge: hermaphrodite tendencies, brittle stems, sensitivity to a particular mould. Traits that were present in the parent line but absent in the selected clone vanish out of the population altogether. A decade of this leaves a market full with variations of the same few plants, and a breeder trying to create something different discovers there is nothing left to cross. Regular seed from an outcrossed line is the store that replenishes the pool, and that reservoir only persist if people keep growing it.
Selecting the Plant Nobody Writes About
Articles on choosing females are everywhere; advice on picking males is scarce, because most people do not keep one long enough to judge. For anyone producing seed, the following are the marks breeders look for.
- Stability. A male that at the same time forms female flowers under ordinary stress is rejected outright; the trait is the last thing worth breeding forward.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with resin on its flower parts and a strong scent indicates it carries the terpene traits that are worth passing on.
- Timing. A male that shows sex first and flowers at the same pace as the females is more workable than an early one that sheds pollen before the female is ready.
- Structure. Short internodes, a thick main stem and a frame that resembles the desired female habit are inherited; a stretched, floppy male hands that on too.
Thinking in Numbers
The error new regular-seed growers make is treating a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a genuine outcrossed line is a sample of a population, and the point of running it is to see the spread and choose from it.
About half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to either discard or judge for breeding. Among the females, look for noticeable variation: stature, finishing time, aroma, density, resistance. That variation 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 cannot supply: a line of selected parents that are their own.
Three Ways to Cross
Owning chosen parents means producing the next generation, and here the choices multiply. The main approaches account for most of what home breeders do.
- Backcross. Cross a chosen offspring again to one of its parents to fix a particular trait. It tightens the range quickly and is used when a single parent has something worth keeping and the other contributed mainly vigour.
- Selected cross. One chosen male to one or a few chosen females, everything else removed. The offspring inherit the traits of the two specific plants and show narrower variation than the original pack. Repeated over generations with consistent selection, this is how a stable line is made.
- Open pollination. Allow every male pollinate every female. It keeps the full diversity of the line, produces a large volume of seed, and does no selection at all. This is how landrace lines are maintained alive, and it is the right approach when the goal is preservation rather than refinement.
Each of these need nothing more than a isolated space for the male, a paintbrush or a paper bag, and patience. None of them calls for the chemical treatment that feminized seed-making requires.
Keeping Old Lines Alive
A number of lines were never been feminized and likely never will be: landraces collected from places where cannabis was grown for centuries, and heirloom hybrids from the early decades of modern breeding. They are available as regular seed since the breeders maintaining them regard the population as the entire value, and selfing a single plant would erase exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from running a modern hybrid. Expect large variation, long flowering times in equatorial lines, lanky plants, and traits that make sense in a mountain valley but not under a tent. Expect also aromas and effects that no longer exist in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line labelled with its origin of origin and the number of generations it has been grown out since the first collection.
The Honest Exclusions
None of the above makes regular seed the best option for everyone, and pretending that it is does the product no service.
A grower with space for three plants who wants each one of them to finish is better served with feminized seed. The same is anyone unable to check the plants each day during the start of flower, since a missed male in a small space seeds the whole crop inside days. A person growing a single autoflower on a balcony has no use from a pack they cannot select from. And a buyer who wants a known clone-only cut reproduced exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to keep and at some point to produce something of their own; for everyone else the regular shelf is best left alone.
Practicalities
Breeder Regular Seeds dispatches every order in plain packaging with the original packs intact inside and no on the exterior to indicate the contents. Orders to the United States are not taken, as seed import is not permitted there. Seed law varies widely 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 both is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article is legal advice.
