Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, marked lower than the feminized packs beside it, and picked up by a shrinking group of people who understand exactly what they are looking for. 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 bookshop next door grows. Every female-only line began as a regular one, each new cross needs a male somewhere in its history, and the diversity of cannabis genetics that survives at all exists because somebody held onto regular seed. Specialists 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 sets out the argument for that half-male pack: what the male is for, what a grower loses by never seeing one, and how to work with a population rather than a copy.
The Other Half of the Genome
The lazy account of a male cannabis plant is «a pollen source», and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and that half is selected with the same care as the mother.
A male contributes structure, vigour, flowering time, tolerance to mould and pests, trichome density and the aromatic profile exactly as the female does; it just shows several of those traits less since it does not grows a smokable flower. Breeders who breed with regular seed spend as much time choosing males as females, which is the work that a feminized cross borrows and can never replicate. Reversing a female yields pollen; it cannot provide a second set of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is made from S1 seeds: a one popular clone, reversed and pollinated with itself. Every generation of that process cuts in half the remaining genetic variation, and after two generations what remains is close to one plant expressed in slightly different forms.
That is acceptable for a consumer who needs that single plant. It is a problem for everyone who comes after. Hidden weaknesses emerge: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Traits that existed in the parent line but not in the chosen clone disappear from the population entirely. A decade of this produces a market full with versions of a dozen clones, and a breeder trying to make something new finds there is little remaining to work with. Regular seed from an outcrossed line is the store that refills the market, and it only persist if somebody grows it.
How to Judge a Male
Articles on selecting females are easy to find; advice on choosing males is scarce, because most people do not keep one past the first week of flower to look. For a grower making seed, the following are the marks breeders look for.
- Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its flower parts and a clear aroma suggests it carries the resin genes that are worth passing on.
- Stability. A male that also shows female flowers under normal stress is rejected without exception; that trait is the one thing worth carrying forward.
- Structure. Tight internodes, a strong main stem and branching that resembles the intended female shape are inherited; a lanky, weak-stemmed male hands that down too.
- Restraint. Males that dump enormous quantities of pollen all at once are frequently also the less selected in other respects; many breeders prefer steady producers.
A Pack Is a Population
The mistake first-time regular-seed buyers fall into is seeing a pack as 10 chances at the same plant. It is the opposite. A pack from a real outcrossed line is a sample of a population, and the value of running it is to observe the spread and select from it.
About half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to either cull or assess for breeding. Within the females, look for real differences: height, flowering time, smell, density, resistance. This spread is not a failure in the seed; it is what the seed is for. The grower who keeps the strongest female and male now owns something a feminized pack cannot supply: a line of chosen parents which are theirs.
From One Pack to the Next
Owning selected parents means producing the next batch, and here the choices open up. Three approaches account for most of what home breeders do.
- Backcross. Cross a selected offspring again to one of its parents to lock in a particular quality. It narrows the range fast and is used when one parent has something worth keeping and the second contributed mostly vigour.
- Open pollination. Let every male reach every female. It keeps the full range of the line, produces a generous volume of seed, and involves no choosing at all. This is how landrace lines are kept going, and it is the right approach when the aim is preservation not refinement.
- Selected cross. One chosen male to one or several picked females, everything else removed. The offspring inherit the traits of two selected plants and express less variation than the original pack. Done over generations with consistent selection, this is how a stable line is made.
All three need only a separate space for the male, a soft brush 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
Some lines have never feminized and likely never will be: landraces gathered from regions where cannabis was grown 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 whole value, and selfing a single clone would erase precisely what makes the line worth preserving.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect wide variation, extended flowering periods in equatorial lines, tall plants, and traits that made sense in a field but not in a small room. There will be too aromas and effects that do not exist in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, with each line marked with its region of origin and the generation it has been reproduced since the original collection.
The Honest Exclusions
None of the above turns regular seed into the right choice for everyone, and pretending that it is does the category no favours.
A grower with space for three plants who needs every one of them to finish is better served with feminized seed. So is anyone who cannot afford to check the plants each day around the start of flower, since a late male in a small space seeds everything inside days. Someone running a single autoflower on a balcony has no value from a population they cannot select from. And a buyer who wants a specific clone-only plant reproduced exactly 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 eventually to produce something of their own; for anyone else the regular shelf is safely ignored where it is.
Before You Buy
Breeder Regular Seeds dispatches each order in plain parcels with the breeder’s packs sealed inside and no on the exterior to indicate the contents. Orders to the United States are not taken, as seed import is not permitted there. Seed law differs widely by country: in a good number of places owning seeds is lawful as collectables while germinating them is not, and in others both are permitted under local rules or neither is. Knowing the position where you live is the buyer’s job, and nothing of this article is legal advice.
