Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, marked lower than the feminized packs beside it, and picked up by a shrinking group of people who know exactly what they are looking for. 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 expands. Every feminized line began as a regular one, each new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all survives because somebody held onto regular seed. Specialists such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article sets out the argument for that unfashionable pack: what the male contributes, what a buyer loses by never seeing one, and how to work with a population instead of a clone.
Not Just Pollen
The easy account 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 half is chosen with the same care as the female.
A male contributes growth habit, hybrid vigour, maturation time, resistance to mould and pests, trichome production and the aromatic chemistry exactly as the female does; it simply shows several of those qualities less because it never produce a smokable flower. Breeders who breed with regular seed invest at least as much time selecting males as females, and this is the work that a feminized line borrows and cannot repeat. Reversing a female yields pollen; it does not give a different line of selected traits.
How Diversity Leaks Away
A great deal of the feminized market is made from S1 seeds: a one famous clone, treated and crossed with itself. Each round of that process halves the surviving genetic diversity, and after two generations what is left is close to one plant expressed across slightly different forms.
This is fine for a consumer who needs that one plant. It is a problem for everyone downstream. Recessive faults emerge: hermaphrodite tendencies, brittle stems, susceptibility to a particular mould. Qualities that existed in the parent line but not in the chosen clone disappear out of the population entirely. A generation of this leaves a market crowded with versions of the same few clones, and a breeder trying to create something new finds there is little remaining to work with. Regular seed from an outcrossed line is the reservoir that replenishes the market, and it only persist if somebody keep growing it.
Selecting the Plant Nobody Writes About
Guides on choosing females are everywhere; advice on picking males is rare, because most growers never keep one long enough to look. For anyone producing seed, the following are the marks breeders watch for.
- Structure. Tight internodes, a thick central stem and branching that matches the desired female habit are inherited; a lanky, weak-stemmed male hands that on too.
- Timing. A male that shows sex early and flowers in step with the females is more useful than an early one that sheds pollen before any female is receptive.
- Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with resin on its sepals and a strong aroma suggests it carries the terpene genes worth passing on.
- Stability. Any male that also forms female pistils under normal stress is rejected without exception; the tendency is the one thing worth breeding into a line.
What 10 Seeds Actually Give You
A mistake first-time regular-seed growers make is seeing a pack as 10 attempts 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 value of running it is to see the range and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives around five females to compare and five males to either discard or judge for breeding. Among the females, look for noticeable variation: stature, flowering time, aroma, density, tolerance. That variation is not a failure in the seed; it is what the seed is selling. The grower who keeps the strongest female and male now owns something a feminized pack can never supply: a pair of selected parents that are theirs.
From One Pack to the Next
Owning chosen parents means making the next batch, and here the choices open up. Three approaches cover most of what home breeders do.
- Open pollination. Let every male pollinate every female. It preserves the whole diversity of the line, produces a generous volume of seed, and does no choosing at all. This is how landrace lines are maintained going, and it is the correct method when the aim is preservation rather than improvement.
- Selected cross. One picked male on one or several picked females, every other plant else removed. The offspring carry the traits of the two specific plants and show less spread than the parent pack. Done over several rounds with stable selection, this is how a stable line is made.
- Backcross. Take a selected offspring back to one of its original parents to lock in a specific quality. It tightens the range quickly and is useful when one parent shows something worth concentrating and the second brought mostly vigour.
All three need only a separate space for the male, a soft brush or a small bag, and patience. None of them calls for the chemical treatment that feminized seed-making requires.
The Seeds That Only Exist as Regulars
A number of lines were never been feminized and probably never will be: landraces collected from regions where cannabis grew over centuries, and heirloom hybrids from the first decades of indoor breeding. They are sold as regular seed since the people keeping them regard diversity as the entire value, and selfing a single clone would destroy exactly what makes the line worth the trouble of preserving.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect wide variation, long flowering periods in equatorial lines, tall plants, and traits that make sense in a field but not in a tent. Expect also flavours and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its region of collection and the generation it has been reproduced since the original collection.
The Honest Exclusions
Nothing of the above turns regular seed the right option for everyone, and pretending otherwise would the category no service.
A grower with space for three plants who wants every one of them to finish is far better off with feminized seed. The same is anyone who cannot afford to inspect the plants each day during the onset of flower, since a missed male in a confined space seeds everything within days. Someone growing a single autoflower on a balcony gets no use from a pack they cannot choose from. And a buyer who is after a specific clone-only plant reproduced as closely as possible 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 of their own; for everyone else the regular shelf is safely ignored alone.
Practicalities
Breeder Regular Seeds dispatches 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 accepted, because seed import is not permitted there. Seed law varies sharply by country: in many places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are allowed under licence or both is. Knowing the position in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.
