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 next to it, and bought by a dwindling group of people who know 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 read it as a library shrinking while the bookshop next door grows. Every feminized line started as a regular one, each new cross requires a male somewhere in its history, and the diversity of cannabis genetics that exists at all exists because somebody kept regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a single plant. This article makes the argument for that half-male pack: what the male contributes, what a buyer loses by never growing one, and how to get value with a pack rather than a clone.
What a Male Plant Is Actually For
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 passes on growth habit, hybrid vigour, flowering speed, resistance to mould and pests, trichome density and the aromatic profile just as the female does; it simply expresses several of those traits less visibly because it does not grows a finished flower. Breeders who breed with regular seed invest as much time choosing males as females, which is the work that a feminized cross borrows and cannot repeat. Feminizing a female gives pollen; it does not give a different line of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized market is built from S1 seeds: a single famous clone, treated and crossed with itself. Each generation of that process halves the remaining genetic diversity, and after a couple of generations what is left is close to one plant expressed across marginally different ways.
That is acceptable for a grower who wants that one plant. It is a loss for everyone downstream. Recessive weaknesses emerge: intersex tendencies, weak stems, susceptibility to a particular mould. Traits that were present in the parent line but absent in the chosen clone disappear out of the gene pool entirely. A decade of this leaves a market full with versions of a dozen plants, and a breeder wanting to create something new discovers there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and it only exists if people keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; advice on picking males is rare, because most growers never keep one past the first week of flower to judge. For anyone producing seed, the following are the signs breeders look for.
- Restraint. Males that dump enormous quantities of pollen all at once are often also the least selected in other respects; breeders prefer moderate producers.
- Stability. Any male that at the same time shows female pistils under normal conditions is discarded outright; that trait is the one thing worth carrying forward.
- Timing. A male that shows sex first and flowers in step with the females is far more useful than an early one that releases pollen before the female is ready.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its sepals and a clear scent suggests it holds the terpene genes that are worth passing on.
A Pack Is a Population
The mistake first-time regular-seed growers make is treating a pack as 10 attempts at the one 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 observe the spread 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 either discard or assess for breeding. Among the females, look for real variation: height, finishing time, smell, density, resistance. This variation is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and male has something a feminized pack can never supply: a line of selected parents that are theirs.
From One Pack to the Next
Owning chosen parents means producing the next generation, and there the options multiply. Three approaches account for most of what small-scale breeders do.
- Open pollination. Let every male pollinate each female. It preserves the full diversity of the line, produces a generous volume of seed, and involves no selection at all. This is how traditional lines are kept going, and it is the correct method when the goal is preservation not refinement.
- Selected cross. One picked male on one or several chosen females, everything else culled. The seeds inherit the traits of the two specific plants and express narrower variation than the parent pack. Done over generations with stable selection, this is how a stable line is made.
- Backcross. Take a selected offspring again to one of its original parents to lock in a specific quality. It tightens the range quickly and is useful when a single plant shows something worth concentrating and the second contributed mainly vigour.
Each of these need only a separate space for the male, a paintbrush or a small bag, and a few weeks. None of them needs the chemical treatment that feminized seed-making does.
Keeping Old Lines Alive
Some lines have never feminized and likely never will be: landraces collected from regions where cannabis was grown for centuries, and old crosses from the early decades of indoor breeding. They are available as regular seed because the people keeping them treat diversity as the whole point, and selfing a single clone would destroy precisely what makes the line worth the trouble of keeping.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect large variation, long flowering periods in tropical lines, tall plants, and traits that made sense in a field but not under a small room. There will be also flavours and effects that no longer appear in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line labelled with its region of origin and the number of generations it has been grown out from the first collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed the right option for everyone, and pretending otherwise does the product no favours.
A grower with room for three plants who wants each one of them to finish is better off with feminized seed. The same is anyone who cannot afford to check the plants each day during the onset of flower, because a missed male in a confined space ruins everything within days. Someone growing a single autoflower on a balcony has no value from a population they cannot select from. And a buyer who wants a known clone-only cut repeated as closely as possible is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to keep and at some point to make something new; for anyone else the regular shelf is safely ignored where it is.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked packaging with the original packs intact inside and no on the outside to reveal the contents. Orders to the United States are not accepted, as seed importation is restricted there. Seed law varies sharply by country: in many places buying seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or both is. Checking the position where you live is the buyer’s job, and no part of this article should be read as legal advice.
