Browse 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 number of people who know exactly what they are looking for. It is tempting to see that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the paperback rack next door grows. Every female-only line began as a regular one, every new cross needs a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all exists only because someone kept regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, sold 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 is for, what a grower loses by not seeing one, and how to work with a population instead of a copy.
Not Just Pollen
The easy description of a male cannabis plant is « a pollen source », and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and that half is selected with the same care as the female.
A male passes on structure, hybrid vigour, maturation time, tolerance to mould and pests, trichome density and the terpene profile exactly as the female does; it just shows some of those qualities less since it never grows a smokable flower. Those who work with regular seed spend at least as much time selecting males as females, and this is the effort that a feminized line borrows and cannot repeat. Feminizing a female gives pollen; it does not provide a different set of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is made from S1 seeds: a single famous clone, treated and crossed with itself. Every round of that selfing halves the remaining genetic variation, and after two rounds what remains is close to one plant expressed across slightly different ways.
That is acceptable for a consumer who needs that one plant. It is a problem for everyone who comes after. Hidden weaknesses emerge: intersex tendencies, brittle stems, sensitivity to one particular mould. Traits that existed in the parent line but not in the selected clone vanish out of the population altogether. A decade of this leaves a market full with variations of a dozen clones, and a breeder wanting to create something new finds there is nothing remaining to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and that reservoir only persist as long as somebody grows it.
Selecting the Plant Nobody Writes About
Guides on choosing females are everywhere; advice on picking males is rare, because most growers never keep one past the first week of flower to look. For anyone making seed, these are the signs breeders watch for.
- Stability. A male that at the same time forms female flowers under normal stress is rejected outright; the trait is the last thing anyone wants breeding forward.
- Timing. A male that shows sex early and matures at the same pace as the females is more workable than a very early one that sheds pollen before any female is ready.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a strong aroma suggests it carries the resin genes that are worth keeping.
- Structure. Tight internodes, a thick main stem and a frame that matches the desired female habit are passed on; a lanky, weak-stemmed male passes that on too.
What 10 Seeds Actually Give You
The error first-time 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 value of growing it is to observe the spread and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds gives something like five females to compare and five males to discard or judge for breeding. Within the females, expect noticeable variation: height, finishing time, aroma, density, tolerance. This spread 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 offer: a line of chosen parents that are theirs.
From One Pack to the Next
Holding chosen parents is only worth something if producing the next batch, and there the options open up. Three approaches account for most of what small-scale breeders attempt.
- Selected cross. One chosen male to one or a few chosen females, every other plant else removed. The seeds inherit the qualities of two selected plants and show less variation than the original pack. Done over generations with stable choices, this is how a new line is built.
- Backcross. Take a selected offspring back to one of its original parents to lock in a particular trait. It tightens the genetics fast and is used when one parent shows something worth concentrating and the other brought mostly vigour.
- Open pollination. Allow every male reach each female. It keeps the whole diversity of the line, produces a large volume of seed, and involves no choosing at all. This is how traditional lines are maintained alive, and it is the correct approach when the goal is preservation not improvement.
Each of these need nothing more than a separate space for the male, a paintbrush or a small bag, and a few weeks. Not one of them calls for the chemical treatment that feminized production does.
The Seeds That Only Exist as Regulars
A number of lines have never feminized and probably never will be: landraces collected from places where cannabis grew over centuries, and old hybrids from the first decades of indoor breeding. They are available as regular seed since the people keeping them treat the population as the entire point, and selfing a single clone would erase precisely what makes the line worth preserving.
Growing a landrace from regular seed is a different experience from running a modern hybrid. There will be wide variation, extended flowering times in equatorial lines, lanky plants, and qualities that make sense in a field but not in a small room. There will be also aromas and chemistry that no longer exist 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 original collection.
The Honest Exclusions
Nothing of the above makes regular seed into the right option for everyone, and claiming that it is would the product no favours.
A grower with space for a handful of plants who wants every one of them to flower is better off with feminized seed. So is anyone who cannot afford to check the plants every day around the onset of flower, because a late male in a confined space ruins the whole crop within days. A person running a single autoflower on a balcony has no use from a pack they cannot choose from. And a buyer who wants a known clone-only plant repeated as closely as possible is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to keep and at some point to make something new; for anyone else the regular shelf is best left where it is.
Practicalities
Breeder Regular Seeds sends each order in plain parcels with the breeder’s packs intact inside and no on the exterior to reveal the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law differs sharply by country: in many places buying seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or both is. Checking the rules where you live is the buyer’s responsibility, and no part of this article is legal advice.
