Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower 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 obsolescence. It is nearer to the truth to read it as a library losing shelves while the bookshop next door grows. Every feminized line started as a regular one, each new cross requires a male at some point in its pedigree, and the breadth of cannabis genetics that exists 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 intended to be a population, not a single plant. This article sets out the case for that half-male pack: what the male contributes, what a buyer gives up by not seeing one, and how to work with a pack instead of a copy.
The Other Half of the Genome
The easy description of a male cannabis plant is “the one that makes pollen”, 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 structure, hybrid vigour, maturation speed, resistance to mould and pests, trichome production and the aromatic profile just as the female does; it simply expresses several of those traits less because it never grows a smokable flower. Breeders who breed with regular seed invest as much time selecting males as females, and this is the effort that a feminized line borrows and cannot repeat. Reversing a female gives pollen; it cannot give a different set of selected traits.
The Narrowing
Much of the feminized market is made from S1 seeds: a one popular clone, treated and crossed with itself. Every round of that process cuts in half the surviving genetic variation, and after a couple of rounds what remains is close to one plant expressed across slightly different forms.
This is acceptable for a grower who needs that single plant. It is a loss for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, weak stems, susceptibility to one particular mould. Qualities that existed in the parent line but absent in the selected clone disappear from the gene pool altogether. A decade of this produces a market full with variations of a dozen plants, and a anyone wanting to create something new discovers there is little left to work with. Regular seed from an outcrossed line is the reservoir that refills the market, and that reservoir only exists as long as people keep growing it.
Selecting the Plant Nobody Writes About
Guides on selecting females are everywhere; guidance on choosing males is scarce, since most people do not keep one past the first week of flower to look. For anyone making seed, the following are the signs breeders watch for.
- 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 any female is receptive.
- Stability. A male that at the same time shows female pistils under ordinary stress is rejected outright; that tendency is the last thing worth carrying into a line.
- Restraint. Plants that release enormous quantities of pollen early are often the least desirable in other respects; breeders prefer moderate shedders.
- Structure. Tight internodes, a thick central stem and a frame that matches the intended female habit are inherited; a lanky, weak-stemmed male hands that down too.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its sepals and a strong aroma indicates it holds the terpene genes that are worth keeping.
A Pack Is a Population
The mistake new regular-seed buyers make is treating a pack as 10 chances at the one plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the point of growing it is to observe the range and select from it.
Roughly half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to either cull or assess for breeding. Within the females, expect real differences: stature, flowering time, aroma, density, resistance. This spread is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and the best male has something a feminized pack can never offer: a pair of chosen parents which are their own.
Making Your Own Seed
Holding chosen parents is only worth something if producing the next generation, and here the choices multiply. Three methods cover most of what home breeders do.
- Backcross. Cross a selected seedling back to one of its parents to fix a specific quality. It narrows the range fast and is used when a single plant shows something worth keeping and the other brought mostly vigour.
- Open pollination. Let each male reach every female. It keeps the whole diversity of the line, makes a generous volume of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the right approach when the aim is preservation not improvement.
- Selected cross. One picked male on one or a few chosen females, everything else culled. The seeds inherit the qualities of two selected plants and express narrower spread than the original pack. Repeated over several rounds with consistent selection, this is how a stable line is built.
Each of these need nothing more than a isolated space for the male, a soft brush or a paper bag, and patience. Not one of them calls for the chemical reversal that feminized production does.
The Seeds That Only Exist as Regulars
A number of lines were never been feminized and likely never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom crosses from the early decades of modern breeding. They are available as regular seed since the people keeping them treat diversity as the entire point, and selfing a single clone would destroy exactly what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is a different experience from running a modern hybrid. Expect large variation, long flowering periods in tropical lines, lanky plants, and qualities that make sense in a field but not in a tent. There will be too flavours and effects that do not appear in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its region of collection and the number of generations it has been reproduced since the first collection.
The Honest Exclusions
None of the above turns regular seed the right option for everyone, and pretending otherwise would the product no service.
A grower with room for a handful of plants who needs every one of them to flower is better off with feminized seed. The same is anyone unable to inspect the plants each day around the start of flower, since a missed male in a confined space ruins the whole crop within days. A person growing a single autoflower on a balcony gets no use from a population they cannot select from. And a buyer who wants a known clone-only plant repeated exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to hold onto and at some point to produce something of their own; for everyone else the back shelf is best ignored alone.
Ordering and the Law
Breeder Regular Seeds dispatches every order in unmarked packaging with the breeder’s packs intact inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, because seed importation is restricted there. Seed law differs sharply by country: in a good number of places buying seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under licence or neither is. Knowing the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article should be read as legal advice.
