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 beside it, and bought by a dwindling group of people who know exactly what they are after. It is tempting to see 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, every new cross requires a male somewhere in its pedigree, and the diversity of cannabis genetics that exists at all exists because someone held onto regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds since 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 buyer loses by never seeing one, and how to work with a pack instead of a copy.
The Other Half of the Genome
The easy 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 chosen with the same attention as the mother.
A male passes on growth habit, hybrid vigour, flowering time, resistance to mould and pests, resin density and the aromatic profile exactly as the female does; it simply shows several of those qualities less visibly because it never grows a finished flower. Those who breed with regular seed invest at least as much time choosing males as females, and this is the effort that a feminized cross borrows and cannot replicate. Feminizing a female gives pollen; it cannot give a different line of selected traits.
How Diversity Leaks Away
Much of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and crossed with itself. Each round of that selfing cuts in half the remaining genetic variation, and after two generations what is left is close to one plant repeated across slightly different ways.
That is acceptable for a consumer who needs that single plant. It is a problem for everyone who comes after. Recessive faults surface: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Traits that were present in the original line but not in the selected clone vanish from the gene pool altogether. A decade of this leaves a market full with versions of the same few plants, and a breeder wanting to make something new finds there is little left to cross. Regular seed from an outcrossed line is the store that refills the pool, and that reservoir can only persist if somebody grows it.
How to Judge a Male
Articles on choosing females are everywhere; advice on picking males is scarce, since most growers do not keep one past the first week of flower to look. For a grower making seed, these are the marks breeders look for.
- Stability. Any male that at the same time shows female pistils under ordinary conditions is rejected without exception; the tendency is the one thing worth carrying into a line.
- Resin on the stem. Rub a stem or a flower sac and smell it. A male with trichomes on its sepals and a clear aroma indicates it carries the terpene traits worth passing on.
- Timing. A male that declares sex first and matures at the same pace as the females is far more workable than a very early one that releases pollen before the female is receptive.
- Structure. Short internodes, a thick central stem and branching that matches the desired female shape are passed on; a stretched, weak-stemmed male hands that down too.
- Restraint. Males that release enormous quantities of pollen all at once are frequently also the least desirable genetically; breeders prefer steady shedders.
What 10 Seeds Actually Give You
A error first-time regular-seed buyers fall into is seeing a pack as 10 attempts 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 see the range and choose from it.
About half the plants will be male, which means a pack of 10 seeds yields something like five females to compare and five males to cull or assess for breeding. Among the females, expect real differences: height, finishing time, smell, density, resistance. That variation is not a flaw in the seed; it is what the seed is for. The grower who keeps the best female and the best male has something a feminized pack can never supply: a line of chosen parents which are their own.
Three Ways to Cross
Holding chosen parents means producing the next generation, and there the choices multiply. The main methods cover most of what small-scale breeders do.
- Backcross. Cross a selected seedling back to one of its parents to fix a particular quality. It narrows the genetics fast and is used when one parent has something worth keeping and the second contributed mostly vigour.
- Selected cross. One picked male on one or several picked females, everything else culled. The offspring inherit the traits of two selected plants and show narrower variation than the parent pack. Done over several rounds with consistent selection, this is how a stable line is made.
- Open pollination. Let every male pollinate every female. It keeps the whole range of the line, produces a large volume of seed, and does no selection at all. This is how landrace lines are maintained going, and it is the correct method when the goal is preservation rather than improvement.
All three require nothing more than a separate space for the male, a paintbrush or a small bag, and a few weeks. Not one of them needs the chemical treatment that feminized seed-making does.
Landraces and Heirloom Lines
A number of lines were never feminized and likely never will be: landraces collected from places where cannabis grew for centuries, and heirloom crosses from the first decades of indoor breeding. They are sold as regular seed because the breeders maintaining them regard the population as the whole value, and selfing a single clone would erase exactly what makes the line worth the trouble of preserving.
Running a landrace from regular seed is different from growing a commercial hybrid. Expect wide variation, long flowering times in equatorial lines, lanky plants, and traits that make sense in a field but not in a tent. There will be also aromas and chemistry that no longer appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, with each line marked with its region of collection and the number of generations it has been reproduced from the first collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed the right option for everyone, and pretending otherwise would the category no service.
A grower with space for a handful of plants who needs every one of them to finish is better served with feminized seed. So is a grower who cannot afford to check the plants every day around the onset of flower, since a late male in a small space seeds the whole crop inside days. Someone running a single autoflower on a balcony gets no use from a population they cannot choose from. And a buyer who wants a specific clone-only plant reproduced as closely as possible is looking for a feminized S1, not a two-parent 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 back shelf is safely left where it is.
Ordering and the Law
Breeder Regular Seeds dispatches every order in unmarked parcels with the original packs intact inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, as seed importation is not permitted there. Seed law varies widely by country: in a good number of places owning seeds is legal as collectables while germinating them is not, and in others both are permitted under local rules or both is. Knowing the position where you live is the buyer’s responsibility, and nothing of this article is legal advice.
