Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, marked cheaper than the feminized packs next to it, and picked up by a dwindling number of people who know exactly what they are looking for. It is tempting to read that as the end of a technology. It is closer to the truth to see it as a library losing shelves while the paperback rack next door expands. Every feminized line began as a regular one, every new cross needs a male at some point in its history, and the diversity of cannabis genetics that survives at all survives because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article makes the case for that half-male pack: what the male contributes, 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 the whole of it. For a breeder it is half the genome of every seed which follows, and that half is selected with the same care as the female.
A male contributes structure, vigour, flowering time, tolerance to mould and pests, trichome density and the terpene profile just as the female does; it simply shows several of those qualities less visibly since it does not produce a finished flower. Breeders who work with regular seed spend as much time choosing males as females, and this is the work that a feminized line borrows and can never repeat. Reversing a female gives pollen; it cannot give a second line of selected traits.
The Narrowing
A great deal of the feminized catalogue is made from S1 seeds: a one famous clone, treated and crossed with itself. Every round of that selfing halves the surviving genetic diversity, and after a couple of generations what remains is close to one plant expressed across slightly different forms.
That is acceptable for a grower who needs that single plant. It is a problem for everyone downstream. Recessive weaknesses emerge: intersex tendencies, weak stems, susceptibility to a particular mould. Qualities that were present in the original line but absent in the chosen clone vanish from the population entirely. A generation of this leaves a market crowded with versions of the same few clones, and a breeder trying to make something new discovers there is nothing remaining to cross. Regular seed from an outcrossed line is the store that refills the pool, and it only exists if people grows it.
Reading a Male Plant
Guides on choosing females are everywhere; advice on choosing males is rare, since most people never keep one long enough to judge. For a grower making seed, these are the marks breeders look for.
- Structure. Short internodes, a strong main stem and branching that matches the desired female habit are inherited; a lanky, weak-stemmed male passes that on too.
- Timing. A male that shows sex first and matures at the same pace as the females is far more workable than an early one that releases pollen before the female is ready.
- Restraint. Males that dump huge amounts of pollen early are often the less desirable in other respects; breeders prefer steady shedders.
- Stability. Any male that at the same time shows female pistils under normal conditions is rejected outright; the tendency is the one thing anyone wants carrying into a line.
Thinking in Numbers
The 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 genuine outcrossed line is a slice of a population, and the point of running it is to see the range and choose from it.
Roughly half the plants will be male, so a pack of 10 seeds gives something like five females to evaluate and five males to discard or assess for breeding. Within the females, expect noticeable variation: stature, flowering time, smell, density, tolerance. This spread is not a flaw 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 supply: a line of chosen parents which are theirs.
Making Your Own Seed
Holding selected parents means producing the next generation, and there the choices open up. Three methods cover most of what small-scale breeders do.
- Open pollination. Let each male reach each female. It preserves the whole diversity of the line, makes a large quantity of seed, and does no selection at all. This is how landrace lines are maintained going, and it is the right method when the aim is preservation rather than improvement.
- Selected cross. One chosen male on one or several picked females, every other plant else removed. The offspring inherit the qualities of two selected plants and show narrower variation than the original pack. Repeated over several rounds with stable selection, this is how a new line is made.
- Backcross. Cross a selected offspring again to one of its original parents to fix a particular trait. It tightens the range fast and is used when a single plant shows something worth keeping and the other contributed mostly vigour.
All three require nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. Not one of them calls for the chemical reversal that feminized seed-making does.
Landraces and Heirloom Lines
Some lines were never been feminized and likely never will be: landraces gathered from places where cannabis grew over centuries, and old crosses from the first decades of modern breeding. They are available as regular seed because the breeders maintaining them treat diversity as the entire value, and selfing a single plant would destroy exactly what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is different from growing a commercial hybrid. There will be wide variation, long flowering periods in tropical lines, tall plants, and traits that made sense in a field but not in a tent. Expect too flavours 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 region of origin and the number of generations it has been grown out since the original collection.
The Honest Exclusions
None of the above turns regular seed the best option for everyone, and claiming that it is does the category no favours.
A grower with space for three plants who wants every one of them to finish is better off with feminized seed. The same is a grower who cannot afford to inspect the plants each day during the start of flower, since a missed male in a small space seeds the whole crop within days. A person running a single autoflower on a balcony has no value from a population they cannot select from. And anyone who wants a known famous plant repeated exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to keep and eventually to make something of their own; for anyone else the regular shelf is safely left alone.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked parcels with the original packs sealed inside and no on the exterior to indicate the contents. Orders to the United States are not taken, as seed importation is not permitted there. Seed law differs 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 permitted under licence or both is. Checking the rules in your own jurisdiction is the buyer’s job, and no part of this article is legal advice.
