Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, marked cheaper than the feminized packs next to it, and picked up by a dwindling group of people who know exactly what they are after. It is tempting to read 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 history, and the diversity of cannabis genetics that survives at all survives only because somebody kept regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, sold in packs of 10 seeds since 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 buyer gives up by never growing one, and how to get value with a population instead of a clone.
What a Male Plant Is Actually For
The lazy account of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. To a breeder it is half the genome of every seed which follows, and half is selected with the same care as the female.
A male passes on structure, vigour, flowering speed, resistance to mould and pests, trichome production and the aromatic profile just as the female does; it simply expresses some of those qualities less because it never produce a finished flower. Those who breed with regular seed invest as much time selecting males as females, and this is the work that a feminized cross borrows and cannot repeat. Feminizing a female gives pollen; it cannot provide a second set of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is made from S1 seeds: a one famous clone, treated and crossed with itself. Every generation of that selfing cuts in half the remaining genetic diversity, and after two generations what remains is essentially one plant repeated in marginally different forms.
That is fine for a consumer who wants that one plant. It is a problem for everyone who comes after. Hidden faults surface: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Qualities that were present in the parent line but not in the selected clone disappear out of the gene pool entirely. A decade of this produces a market crowded with variations of the same few clones, and a breeder wanting to make something different discovers there is nothing left to cross. Regular seed from an outcrossed line is the store that refills the market, and that reservoir only persist as long as people keep growing it.
How to Judge a Male
Guides on choosing females are everywhere; guidance on picking males is scarce, because most people never 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 sepals and a clear aroma indicates it holds the terpene traits that are worth keeping.
- Timing. A male that declares sex first and matures at the same pace as the females is more workable than an early one that releases pollen before any female is ready.
- Structure. Tight internodes, a strong main stem and a frame that resembles the desired female shape are passed on; a lanky, floppy male hands that on too.
- Stability. A male that at the same time shows female flowers under normal stress is discarded without exception; the tendency is the one thing worth carrying into a line.
A Pack Is a Population
A mistake new regular-seed buyers fall into is treating a pack as 10 attempts at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the point of growing it is to observe the range and choose from it.
About half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to cull or assess for breeding. Within the females, expect real differences: height, flowering time, aroma, density, tolerance. That variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male has something a feminized pack can never supply: a line of chosen parents that are their own.
Three Ways to Cross
Holding selected parents is only worth something if making the next batch, and here the options multiply. The main methods account for most of what small-scale breeders do.
- Selected cross. One chosen male to one or a few chosen females, every other plant else culled. The seeds inherit the qualities of the two specific plants and show less spread than the original pack. Done over generations with stable selection, this is how a stable line is made.
- Open pollination. Allow each male reach every female. It keeps the full range of the line, makes a generous volume of seed, and does no selection at all. This is how landrace lines are kept alive, and it is the right method when the goal is preservation not refinement.
- Backcross. Cross a selected seedling back to one of its original parents to fix a particular trait. It tightens the genetics fast and is useful when one parent shows something worth keeping and the second contributed mostly vigour.
All three require nothing more than a isolated space for the male, a soft brush or a small bag, and patience. None of them calls for the chemical treatment that feminized production does.
Landraces and Heirloom Lines
Some lines have never been feminized and likely never will be: landraces collected from regions where cannabis was grown over centuries, and heirloom crosses from the first decades of modern breeding. They are sold as regular seed because the people maintaining them treat diversity as the entire point, and reversing a single clone would destroy exactly what makes the line worth preserving.
Running a landrace from regular seed is different from running a modern hybrid. There will be wide variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a field but not under a tent. There will be too flavours and chemistry that do not exist in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of collection and the generation it has been reproduced from the original collection.
When the Library Is the Wrong Shop
None of the above turns regular seed the best choice for everyone, and pretending that it is does the category no service.
A grower with room for a handful of plants who needs each one of them to flower is better off with feminized seed. So is a grower who cannot afford to inspect the plants each day around the onset of flower, because a missed male in a small space ruins the whole crop within days. A person growing a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who is after 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 keep and at some point to make something new; for everyone 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 intact inside and no on the exterior to reveal the contents. Orders to the United States are not accepted, because seed import is restricted there. Seed law varies widely by country: in a good number of places owning seeds is lawful as genetic preservation while germinating them is not, and in others the two are allowed under local rules or both is. Knowing the position in your own jurisdiction is the buyer’s job, and nothing of this article should be read as legal advice.
