Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and picked up by a shrinking group of people who know exactly what they are after. It is easy to see that as the end of a technology. It is closer to the truth to see it as a library shrinking while the paperback rack next door grows. Every female-only line began as a regular one, each new cross requires a male at some point in its pedigree, and the diversity of cannabis genetics that exists at all survives only because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, sold 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 grower loses by never seeing one, and how to get value with a pack rather than a clone.
Not Just Pollen
The lazy description of a male cannabis plant is “a pollen source”, and to a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and that half is chosen with the same care as the female.
A male contributes structure, vigour, flowering speed, tolerance to mould and pests, trichome density and the aromatic chemistry just as the female does; it simply shows some of those qualities less visibly since it does not grows a finished flower. Those who breed with regular seed spend as much time choosing males as females, and this is the work that a feminized line inherits and can never replicate. Reversing a female gives pollen; it cannot give a second set of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized market is built from S1 seeds: a one popular clone, reversed and crossed with itself. Every round of that process cuts in half the surviving genetic variation, and after a couple of generations what is left is close to one plant expressed in slightly different ways.
This is acceptable for a grower who needs that single plant. It is a loss for everyone who comes after. Recessive weaknesses surface: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Traits that were present in the original line but not in the selected clone vanish out of the population entirely. A decade of this leaves a market full with variations of the same few plants, and a breeder trying to make something different finds there is nothing remaining to cross. Regular seed from a true outcrossed line is the store that refills the pool, and it only persist if people keep growing it.
Reading a Male Plant
Guides on selecting females are everywhere; advice on picking males is scarce, since most people never keep one long enough to judge. For anyone making seed, the following are the signs breeders look for.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with resin on its sepals and a clear scent indicates it carries the terpene traits that are worth keeping.
- Restraint. Plants that dump huge quantities of pollen early are frequently also the less desirable in other respects; breeders prefer moderate producers.
- Timing. A male that declares sex first and flowers at the same pace as the females is more workable than a very early one that releases pollen before any female is ready.
- Structure. Tight internodes, a strong central stem and a frame that resembles the intended female habit are inherited; a lanky, weak-stemmed male hands that down too.
What 10 Seeds Actually Give You
The mistake new regular-seed growers fall into is seeing 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 running it is to see the spread and select from it.
Roughly half the plants will be male, so a pack of 10 seeds yields something like five females to compare and five males to either cull or assess for breeding. Within the females, expect noticeable differences: stature, finishing time, aroma, 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 now owns something a feminized pack can never supply: a line of chosen parents that are theirs.
From One Pack to the Next
Holding selected parents means producing the next batch, and there the choices open up. Three methods account for most of what small-scale breeders attempt.
- Selected cross. One chosen male to one or a few picked females, everything else removed. The offspring inherit the qualities of the two selected plants and express less spread than the parent pack. Repeated over generations with consistent choices, this is how a stable line is built.
- Backcross. Cross a chosen offspring again to one of its parents to lock in a particular trait. It tightens the range quickly and is used when a single parent shows something worth concentrating and the other contributed mostly vigour.
- Open pollination. Let every male pollinate every female. It keeps the full diversity of the line, produces a generous quantity of seed, and does no selection at all. This is how landrace lines are kept alive, and it is the right approach when the goal is preservation not refinement.
All three need only a isolated space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical treatment that feminized production does.
The Seeds That Only Exist as Regulars
Some lines were never been feminized and probably never will be: landraces collected from regions where cannabis was grown for centuries, and heirloom crosses from the early decades of indoor breeding. They are sold as regular seed since the people keeping them regard the population as the whole value, and reversing a single clone would erase exactly what makes the line worth keeping.
Running a landrace from regular seed is a different experience from running a modern hybrid. Expect large variation, long flowering times in tropical lines, lanky plants, and qualities that make sense in a mountain valley but not under a tent. There will be too flavours and effects that do not appear in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its origin of collection and the generation it has been grown out since the first collection.
When the Library Is the Wrong Shop
None of the above turns regular seed the best choice for everyone, and claiming that it is does the category no favours.
A grower with room for three plants who wants each one of them to finish is better off with feminized seed. So is anyone who cannot afford to inspect the plants every day during the start of flower, because a late male in a confined space seeds everything within days. A person running a single autoflower on a balcony gets no value from a population they cannot select from. And anyone who is after a specific famous cut reproduced as closely as possible is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to hold onto and at some point to make something new; for anyone else the regular shelf is best ignored where it is.
Ordering and the Law
Breeder Regular Seeds sends each order in unmarked packaging with the breeder’s packs sealed inside and nothing on the outside to reveal the contents. Orders to the United States are not taken, as seed import is not permitted there. Seed law varies sharply by country: in a good number of places buying seeds is legal as collectables while germinating them is not, and in others the two are permitted under local rules or neither is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article is legal advice.
