Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced cheaper than the feminized packs beside it, and bought by a shrinking number of people who know exactly what they are after. It is tempting to read that as the end of a technology. It is nearer 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 requires a male somewhere in its history, and the diversity of cannabis genetics that survives at all exists only because somebody kept regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article makes the argument for that unfashionable pack: what the male contributes, what a grower gives up by never seeing one, and how to work with a pack rather than a clone.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and half is chosen with the same attention as the mother.
A male contributes growth habit, vigour, maturation speed, resistance to mould and pests, resin density and the terpene profile just as the female does; it simply shows some of those qualities less because it never grows a finished flower. Breeders who work with regular seed spend as much time choosing males as females, which is the effort that a feminized line inherits and can never repeat. Reversing a female gives pollen; it does not provide a different line of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is made from S1 seeds: a one famous clone, reversed and pollinated with itself. Every generation of that process halves the surviving genetic diversity, and after two rounds what remains is essentially one plant repeated in marginally different forms.
This is fine for a consumer who needs that one plant. It is a problem for everyone downstream. Hidden weaknesses emerge: hermaphrodite tendencies, brittle stems, sensitivity to one particular mould. Qualities that were present in the parent line but not in the selected clone disappear from the population altogether. A generation of such breeding produces a market crowded with versions of the same few plants, and a anyone trying to make something different finds there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and it can only exists as long as people keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; advice on picking males is rare, since most people never keep one long enough to look. For a grower making seed, the following are the signs breeders look for.
- Timing. A male that shows sex first and flowers in step with the females is far more workable than a very early one that releases pollen before the female is ready.
- Structure. Tight internodes, a thick central stem and branching that resembles the intended female habit are inherited; a lanky, floppy male hands that down too.
- Restraint. Plants that release huge quantities of pollen all at once are frequently the least desirable in other respects; breeders favour moderate producers.
- Stability. A male that at the same time forms female pistils under normal stress is rejected outright; that trait is the last thing anyone wants breeding forward.
What 10 Seeds Actually Give You
A error first-time regular-seed buyers fall into is seeing a pack as 10 chances at the same plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the value of growing it is to observe the spread and choose from it.
Roughly half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to discard or judge for breeding. Among the females, expect noticeable variation: height, finishing time, aroma, density, resistance. This variation is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and male now owns something a feminized pack can never offer: a pair of selected parents that are theirs.
Three Ways to Cross
Owning selected parents means making the next generation, and there the options multiply. Three methods cover most of what home breeders do.
- Open pollination. Allow each male reach each 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 kept going, and it is the right method when the goal is preservation rather than refinement.
- Selected cross. One picked male to one or a few chosen females, everything else culled. The offspring inherit the qualities of the two selected plants and show less spread than the parent pack. Done over generations with stable selection, this is how a new line is built.
- Backcross. Take a selected seedling back to one of its original parents to fix a particular quality. It tightens the genetics fast and is useful when one plant shows something worth keeping and the second brought mainly vigour.
Each of these require only a isolated space for the male, a soft brush or a small bag, and a few weeks. None of them calls for the chemical reversal that feminized production does.
Keeping Old Lines Alive
A number of lines were never feminized and probably never will be: landraces collected from regions where cannabis grew over centuries, and old hybrids from the first decades of modern breeding. They are sold as regular seed because the people keeping them treat the population as the entire value, and reversing a single plant would erase exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from growing a modern hybrid. Expect wide variation, extended flowering periods in equatorial lines, tall plants, and traits that made sense in a field but not under a small room. Expect also flavours and chemistry that no longer exist in the commercial market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line labelled with its origin of collection and the number of generations it has been reproduced from the original collection.
The Honest Exclusions
None of the above makes regular seed the best choice for everyone, and pretending otherwise would the product no service.
A grower with space for a handful of plants who needs each one of them to flower is better served with feminized seed. The same is anyone who cannot afford to check the plants every day during the start of flower, since a missed male in a small space seeds the whole crop inside days. A person running a single autoflower on a balcony gets no use from a population they cannot choose from. And a buyer who wants a known clone-only cut repeated exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to hold onto and eventually 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 no on the exterior to reveal the contents. Orders to the United States are not accepted, as seed import is restricted there. Seed law varies widely by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others the two are allowed 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.
