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 shrinking number of people who know exactly what they are looking for. It is easy to see that as the end of a technology. It is nearer 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, each new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back 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 contributes, what a grower loses by never growing one, and how to get value with a pack instead of a copy.
Not Just Pollen
The easy account of a male cannabis plant is “the one that makes pollen”, 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 half is selected with the same attention as the mother.
A male contributes growth habit, hybrid vigour, flowering speed, tolerance to mould and pests, resin density and the aromatic chemistry just as the female does; it just expresses several of those qualities less visibly because it never produce a finished flower. Breeders who breed with regular seed invest as much time selecting males as females, and this is the work that a feminized line borrows and cannot replicate. Reversing a female yields pollen; it cannot provide a different set of selected genes.
The Narrowing
A great deal of the feminized market is made from S1 seeds: a single popular clone, reversed and pollinated with itself. Every round of that process cuts in half the surviving genetic diversity, and after a couple of rounds what is left is essentially one plant expressed across marginally different ways.
This is acceptable for a consumer who needs that one plant. It is a loss for everyone who comes after. Recessive weaknesses emerge: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Traits that existed in the parent line but absent in the chosen clone disappear out of the population altogether. A decade of such breeding leaves a market crowded with versions of a dozen clones, and a breeder trying to create something new finds there is little left to cross. Regular seed from a true outcrossed line is the reservoir that refills the pool, and it only exists as long as somebody keep growing it.
How to Judge a Male
Guides on choosing females are easy to find; guidance on choosing males is scarce, since most people never keep one long enough to look. For anyone making seed, these are the marks breeders look for.
- Timing. A male that shows sex first and flowers at the same pace as the females is more useful than a very early one that sheds pollen before any female is ready.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with trichomes on its sepals and a strong scent suggests it carries the terpene traits that are worth passing on.
- Structure. Tight internodes, a thick central stem and a frame that resembles the intended female habit are inherited; a lanky, weak-stemmed male hands that down too.
- Stability. A male that at the same time shows female flowers under ordinary conditions is discarded outright; the tendency is the one thing anyone wants carrying into a line.
A Pack Is a Population
The error first-time regular-seed growers fall into is seeing a pack as 10 chances at the one 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 observe the range 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 judge for breeding. Within the females, expect real variation: stature, flowering time, smell, density, tolerance. This variation is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and the best male has something a feminized pack cannot supply: a pair of selected parents which are theirs.
From One Pack to the Next
Owning selected parents is only worth something if producing the next generation, and here the options open up. The main methods account for most of what small-scale breeders do.
- Open pollination. Let each male pollinate every female. It preserves the whole diversity of the line, produces a generous quantity of seed, and involves no choosing at all. This is how traditional lines are kept going, and it is the right approach when the goal is preservation not improvement.
- Backcross. Cross a selected offspring back to one of its parents to lock in a specific quality. It tightens the genetics quickly and is useful when one parent shows something worth concentrating and the other brought mainly vigour.
- Selected cross. One picked male to one or several picked females, everything else culled. The offspring carry the traits of two specific plants and express narrower spread than the parent pack. Done over generations with consistent selection, this is how a stable line is made.
Each of these require only a isolated space for the male, a paintbrush or a paper bag, and patience. Not one of them calls for the chemical reversal that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines have never feminized and likely never will be: landraces gathered from regions where cannabis was grown over centuries, and heirloom hybrids from the first decades of indoor breeding. They are available as regular seed because the breeders keeping them treat diversity as the whole point, and selfing a single plant would destroy exactly what makes the line worth keeping.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect wide variation, extended flowering periods in tropical lines, tall plants, and qualities that made sense in a field but not in a tent. Expect too flavours and chemistry that do not exist in the commercial market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its region 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 claiming that it is would the category no favours.
A grower with space for a handful of plants who needs each one of them to flower is better served with feminized seed. So is anyone unable to check the plants every day during the onset of flower, because a late male in a confined space seeds the whole crop within days. Someone growing a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who wants a specific clone-only cut repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to hold onto and eventually to make something of their own; for everyone else the regular shelf is safely ignored alone.
Practicalities
Breeder Regular Seeds sends each order in plain packaging with the breeder’s packs intact inside and nothing on the outside to indicate the contents. Orders to the United States are not accepted, as seed importation is not permitted there. Seed law differs sharply by country: in many places owning seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the position where you live is the buyer’s job, and no part of this article is legal advice.
