Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced lower than the feminized packs next to it, and bought by a shrinking group of people who know exactly what they are looking for. It is easy to read that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the bookshop next door expands. Every female-only line started as a regular one, every new cross needs a male at some point in its history, and the diversity of cannabis genetics that survives at all exists because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article makes the argument for that unfashionable pack: what the male contributes, what a grower gives up by not seeing one, and how to work with a population rather than a copy.
Not Just Pollen
The easy account of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and half is selected with the same care as the mother.
A male contributes structure, vigour, flowering time, tolerance to mould and pests, resin production and the terpene profile just as the female does; it just expresses several of those traits less visibly because it does not grows a finished flower. Those who work with regular seed spend at least as much time selecting males as females, and this is the work that a feminized cross inherits and cannot replicate. Feminizing a female gives pollen; it does not give a different line of selected traits.
How Diversity Leaks Away
A great deal of the feminized catalogue is made from S1 seeds: a one famous clone, reversed and crossed with itself. Each generation of that process halves the remaining genetic diversity, and after a couple of rounds what remains is essentially one plant repeated in slightly different ways.
That is acceptable for a grower who needs that single plant. It is a loss for everyone who comes after. Hidden faults surface: intersex tendencies, weak stems, susceptibility to a particular mould. Traits that were present in the original line but not in the chosen clone disappear out of the population altogether. A generation of this leaves a market full with variations of a dozen clones, and a breeder trying to create something new finds there is nothing remaining to cross. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and that reservoir only persist as long as somebody keep growing it.
Reading a Male Plant
Guides on choosing females are everywhere; guidance on picking males is rare, because most growers never keep one past the first week of flower to look. For a grower making seed, these are the marks breeders watch for.
- Timing. A male that declares sex first and matures at the same pace as the females is more useful than a very early one that releases pollen before the female is ready.
- Stability. A male that also forms female flowers under normal stress is rejected without exception; the tendency is the last thing worth carrying into a line.
- Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with trichomes on its flower parts and a strong aroma indicates it carries the resin traits worth passing on.
- Restraint. Plants that dump huge quantities of pollen early are frequently the less desirable genetically; breeders favour moderate shedders.
- Structure. Short internodes, a thick central stem and a frame that resembles the desired female habit are inherited; a stretched, weak-stemmed male hands that down too.
What 10 Seeds Actually Give You
The error new regular-seed growers fall into is treating a pack as 10 attempts at the same plant. It is the opposite. 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.
About half the plants will be male, so a pack of 10 seeds yields around five females to evaluate and five males to discard or judge for breeding. Within the females, look for noticeable differences: stature, finishing time, smell, bud structure, tolerance. This variation is not a flaw 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 pair of selected parents which are theirs.
Three Ways to Cross
Owning chosen parents means producing the next generation, and there the choices open up. Three approaches cover most of what home breeders attempt.
- Selected cross. One chosen male on one or several picked females, every other plant else removed. The offspring inherit the qualities of the two specific plants and express narrower spread than the parent pack. Repeated over generations with consistent selection, this is how a stable line is made.
- Open pollination. Allow each male pollinate every female. It keeps the full diversity of the line, produces a generous volume of seed, and involves no choosing at all. This is how traditional lines are maintained going, and it is the correct method when the aim is preservation rather than improvement.
- Backcross. Take a selected offspring back to one of its original parents to fix a specific quality. It narrows the range quickly and is used when a single plant shows something worth keeping and the other brought mostly vigour.
Each of these need only a separate space for the male, a paintbrush or a paper bag, and patience. None of them calls for the chemical reversal that feminized production does.
Landraces and Heirloom Lines
A number of lines have never feminized and probably never will be: landraces collected from regions where cannabis was grown over centuries, and heirloom hybrids from the early decades of modern breeding. They are available as regular seed since the breeders keeping them treat diversity as the entire point, and selfing a single plant would destroy exactly 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, lanky plants, and qualities that made sense in a field but not in a tent. There will be too aromas and effects that do not appear in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line marked with its origin of collection and the number of generations it has been grown out from the first collection.
Who Should Not Buy Regular Seeds
None of the above turns regular seed into the right choice for everyone, and pretending that it is does the category no service.
A grower with space for a handful of plants who needs each one of them to flower is better off with feminized seed. The same is anyone unable to check the plants every day during the onset of flower, because a missed male in a confined space ruins everything within days. A person running a single autoflower on a balcony has no use from a population they cannot choose 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 wants to choose, to keep and eventually to make something of their own; for anyone else the regular shelf is best left alone.
Before You Buy
Breeder Regular Seeds sends each order in unmarked parcels with the original packs sealed inside and no on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law varies sharply by country: in many places owning seeds is legal as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the rules in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
