Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced lower than the feminized packs beside it, and bought by a dwindling group of people who know exactly what they are after. It is easy to read that as obsolescence. It is closer to the truth to read it as a library losing shelves while the paperback rack next door expands. Every female-only line began as a regular one, each new cross requires a male at some point in its pedigree, and the breadth of cannabis genetics that survives at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article makes the case for that half-male pack: what the male is for, what a grower gives up by not seeing one, and how to get value with a population instead of a copy.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and half is chosen with the same care as the mother.
A male passes on structure, hybrid vigour, flowering time, resistance to mould and pests, resin production and the terpene chemistry exactly as the female does; it just shows several of those qualities less visibly because it never produce a finished flower. Those who breed with regular seed invest as much time selecting males as females, which is the effort that a feminized line borrows and can never repeat. Feminizing a female yields pollen; it does not provide a different set of selected traits.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one famous clone, treated and crossed with itself. Every round of that process cuts in half the remaining genetic diversity, and after a couple of rounds what is left is essentially one plant repeated across slightly different ways.
That is fine for a grower who needs that one plant. It is a problem for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, brittle stems, sensitivity to a particular mould. Traits that were present in the original line but absent in the selected clone disappear from the gene pool altogether. A decade of this leaves a market full with variations of the same few clones, and a breeder trying to create something new finds there is little left to work with. Regular seed from a true outcrossed line is the reservoir that refills the market, and that reservoir only exists as long as somebody grows it.
Selecting the Plant Nobody Writes About
Articles on selecting females are everywhere; advice on picking males is scarce, since most people do not keep one long enough to judge. For a grower producing seed, the following are the marks breeders look for.
- Restraint. Plants that release huge quantities of pollen early are frequently the less desirable in other respects; breeders prefer moderate shedders.
- Timing. A male that shows sex early and matures in step with the females is far more workable than an early one that releases pollen before any female is ready.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its flower parts and a strong scent suggests it carries the resin traits that are worth keeping.
- Structure. Tight internodes, a thick central stem and branching that matches the intended female shape are passed on; a lanky, weak-stemmed male hands that on too.
What 10 Seeds Actually Give You
The mistake new regular-seed buyers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the point of running it is to see the spread and choose 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 cull or assess for breeding. Within the females, expect real differences: height, finishing time, smell, bud structure, resistance. That variation is not a failure in the seed; it is what the seed is selling. The grower who keeps the best female and the best male has something a feminized pack can never supply: a pair of selected parents which are theirs.
Three Ways to Cross
Owning selected parents is only worth something if making the next generation, and there the options multiply. The main approaches account for most of what home breeders do.
- Selected cross. One picked male to one or a few picked females, every other plant else culled. The offspring inherit the qualities of two specific plants and show narrower spread than the parent pack. Done over generations with stable choices, this is how a new line is made.
- Open pollination. Let every male pollinate every female. It keeps the full diversity of the line, makes a generous quantity of seed, and does no choosing at all. This is how landrace lines are maintained going, and it is the right method when the aim is preservation not improvement.
- Backcross. Cross a chosen offspring back to one of its parents to lock in a specific quality. It tightens the range quickly and is used when a single plant shows something worth keeping and the other contributed mainly vigour.
Each of these need only a separate space for the male, a paintbrush or a paper bag, and a few weeks. Not one of them needs the chemical treatment that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines were never feminized and likely never will be: landraces collected from places where cannabis was grown over centuries, and old crosses from the first decades of indoor breeding. They are available as regular seed since the people maintaining them regard the population as the whole point, and selfing a single plant would erase exactly what makes the line worth keeping.
Running a landrace from regular seed is different from running a modern hybrid. There will be large variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a field but not in a tent. Expect also aromas and effects that no longer appear in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its origin of collection and the generation it has been reproduced from the original collection.
Who Should Not Buy Regular Seeds
None of the above turns regular seed the best option for everyone, and pretending otherwise would the category no service.
A grower with space for a handful of plants who needs each one of them to finish is far better served with feminized seed. So is anyone unable to inspect the plants every day during the onset of flower, because a missed male in a confined space ruins the whole crop within days. Someone running a single autoflower on a balcony gets no value from a pack they cannot select from. And anyone who wants a known famous cut repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to keep and at some point to make something of their own; for anyone else the back shelf is safely ignored alone.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked parcels with the breeder’s packs sealed inside and nothing on the outside to reveal the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law varies sharply by country: in a good number of places buying seeds is lawful as collectables 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 nothing of this article should be read as legal advice.
