Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, priced cheaper than the feminized packs beside it, and picked up by a shrinking group of people who understand exactly what they are after. It is easy to read that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the bookshop next door grows. Every female-only line started as a regular one, each new cross needs a male at some point in its pedigree, and the diversity of cannabis genetics that survives at all exists only because someone kept regular seed. Dedicated sellers such as https://breederregularseeds.com stock 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 case for that half-male pack: what the male is for, what a buyer 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 to a flower grower that is all it. To a breeder it is half the genome of every seed that follows, and that half is selected with the same attention as the female.

A male contributes growth habit, hybrid vigour, flowering speed, resistance to mould and pests, resin production and the aromatic profile just as the female does; it just expresses several of those traits less visibly since it never grows a finished flower. Breeders who breed with regular seed invest at least as much time selecting males as females, which is the work that a feminized cross borrows and can never repeat. Feminizing a female yields pollen; it cannot give a different line of selected genes.

What Happens When Lines Are Only Selfed

Much of the feminized market is built from S1 seeds: a single popular clone, reversed and crossed with itself. Every generation of that selfing cuts in half the surviving genetic variation, and after two rounds what is left is close to one plant expressed in slightly different forms.

That is fine for a consumer who wants that single plant. It is a problem for everyone who comes after. Hidden faults surface: intersex tendencies, weak stems, sensitivity to a particular mould. Qualities that existed in the parent line but absent in the selected clone disappear from the population altogether. A generation of this produces a market full with versions of a dozen clones, and a anyone trying to make something different finds there is little remaining to cross. Regular seed from a true outcrossed line is the reservoir that replenishes the market, and it only persist as long as somebody grows it.

Reading a Male Plant

Guides on selecting females are everywhere; advice on picking males is scarce, because most growers do not keep one long enough to look. For a grower producing seed, the following are the marks breeders watch for.

• Structure. Tight internodes, a strong main stem and a frame that matches the intended female habit are inherited; a lanky, weak-stemmed male hands that down too.
• Timing. A male that declares sex early and matures in step with the females is more workable than a very early one that sheds pollen before the female is ready.
• Stability. Any male that at the same time forms female pistils under ordinary stress is discarded outright; the trait is the one thing anyone wants carrying forward.
• Restraint. Males that dump enormous quantities of pollen all at once are frequently the least selected in other respects; many breeders prefer moderate shedders.
• Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with resin on its flower parts and a clear aroma indicates it holds the terpene genes worth keeping.

What 10 Seeds Actually Give You

A error new regular-seed growers 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 slice of a population, and the point of growing it is to see the range and select from it.

Roughly half the plants will be male, which means a pack of 10 seeds yields around five females to compare and five males to discard or assess for breeding. Among the females, look for real differences: stature, flowering time, aroma, bud structure, tolerance. That spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male has something a feminized pack cannot offer: a pair of chosen parents which are their own.

Making Your Own Seed

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

• Backcross. Cross a selected offspring again to one of its original parents to fix a specific trait. It tightens the range fast and is used when a single parent has something worth keeping and the second brought mostly vigour.
• Selected cross. One chosen male on one or a few chosen females, everything else culled. The offspring inherit the qualities of the two selected plants and express narrower spread than the original pack. Done over several rounds with stable selection, this is how a stable line is built.
• Open pollination. Let each male reach every female. It preserves the whole diversity of the line, produces a large quantity of seed, and does no selection at all. This is how traditional lines are maintained going, and it is the right method when the aim is preservation not improvement.

Each of these need nothing more than a isolated 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.

Keeping Old Lines Alive

Some lines were never feminized and likely never will be: landraces gathered from places where cannabis was grown over centuries, and heirloom hybrids from the first decades of modern breeding. They are sold as regular seed since the breeders keeping them regard the population as the whole value, and selfing a single plant would erase exactly what makes the line worth keeping.

Running a landrace from regular seed is a different experience from running a commercial hybrid. There will be large variation, extended flowering times in equatorial lines, lanky plants, and qualities that made sense in a field but not in a small room. Expect too aromas and effects that do not appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its region of collection and the generation it has been grown out from the original collection.

Who Should Not Buy Regular Seeds

Nothing of the above makes regular seed into the right choice for everyone, and pretending otherwise would the category no favours.

A grower with room for three plants who needs each one of them to flower is better served with feminized seed. So is a grower unable to check the plants every day during the start of flower, since a missed male in a confined space seeds everything inside days. A person growing a single autoflower on a balcony has no use from a pack they cannot choose from. And anyone who is after a known famous plant 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 produce something of their own; for everyone else the regular shelf is best ignored where it is.

Practicalities

Breeder Regular Seeds dispatches every order in unmarked packaging with the original packs sealed inside and no on the exterior to reveal the contents. Orders to the United States are not accepted, because seed importation is not permitted there. Seed law varies sharply by country: in a good number of places buying seeds is legal as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Checking the position in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
