Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, marked lower than the feminized packs next to it, and bought by a shrinking group of people who understand exactly what they are looking for. It is tempting to read that as obsolescence. It is nearer to the truth to see it as a library shrinking while the paperback rack next door expands. Every female-only line started as a regular one, each new cross requires a male somewhere in its pedigree, and the diversity of cannabis genetics that exists at all survives because someone kept regular seed. Specialists such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a single plant. This article sets out the case for that unfashionable pack: what the male contributes, what a buyer loses by not growing one, and how to work with a population rather than a copy.
The Other Half of the Genome
The easy description of a male cannabis plant is “a pollen source”, and to a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and half is chosen with the same attention as the female.
A male passes on growth habit, vigour, flowering speed, tolerance to mould and pests, resin production and the aromatic chemistry just as the female does; it just expresses some of those qualities less since it does not produce a smokable flower. Those who work with regular seed spend as much time choosing males as females, which is the work that a feminized cross borrows and cannot replicate. Feminizing a female yields pollen; it does not give a different line of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized catalogue is built from S1 seeds: a single popular clone, treated and pollinated with itself. Each round of that process halves the surviving genetic variation, and after two rounds what is left is essentially one plant repeated in slightly different ways.
This is acceptable for a grower who needs that one plant. It is a loss for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, brittle stems, sensitivity to one particular mould. Traits that existed in the original line but not in the selected clone vanish from the population entirely. A decade of this leaves a market crowded with variations of a dozen clones, and a anyone wanting to create something different finds there is little left to cross. Regular seed from a true outcrossed line is the store that refills the pool, and that reservoir only persist as long as somebody keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; advice on choosing males is rare, because most people do not keep one long enough to look. For anyone making seed, the following are the marks breeders watch for.
- Timing. A male that declares sex early and matures at the same pace as the females is more workable than an early one that sheds pollen before any female is ready.
- Restraint. Plants that release enormous quantities of pollen early are frequently the least desirable genetically; breeders prefer moderate producers.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with resin on its sepals and a clear aroma suggests it holds the resin traits worth passing on.
- Stability. A male that also shows female pistils under ordinary stress is discarded outright; the tendency is the last thing worth carrying into a line.
What 10 Seeds Actually Give You
The mistake first-time regular-seed growers fall into is seeing a pack as 10 chances at the same plant. It is nothing of the kind. A pack from a genuine outcrossed line is a slice of a population, and the point of growing it is to see the spread and choose from it.
Roughly 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 judge for breeding. Among the females, expect noticeable differences: height, flowering time, aroma, density, tolerance. This variation is not a failure in the seed; it is what the seed is for. The grower who keeps the strongest female and the best male now owns something a feminized pack cannot supply: a pair of selected parents that are theirs.
From One Pack to the Next
Holding chosen parents means making the next generation, and there the options multiply. Three approaches account for most of what home breeders do.
- Open pollination. Allow every male pollinate each female. It keeps the whole diversity of the line, produces a large volume of seed, and involves no selection at all. This is how traditional lines are maintained going, and it is the right method when the goal is preservation not improvement.
- Selected cross. One picked male to one or several picked females, everything else culled. The offspring carry the qualities of the two selected plants and show narrower spread than the parent pack. Repeated over several rounds with consistent selection, this is how a stable line is built.
- Backcross. Take a selected offspring again to one of its original parents to fix a specific quality. It narrows the genetics quickly and is useful when a single parent has something worth keeping and the other contributed mainly vigour.
All three need only a separate space for the male, a soft brush or a paper bag, and patience. None of them needs the chemical reversal that feminized production requires.
Keeping Old Lines Alive
Some lines have never been feminized and probably never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom hybrids from the early decades of modern breeding. They are available as regular seed because the breeders keeping them treat diversity as the entire value, and reversing a single clone would destroy exactly what makes the line worth the trouble of preserving.
Running a landrace from regular seed is different from growing a modern hybrid. There will be wide variation, long flowering times in tropical lines, lanky plants, and traits that made sense in a field but not in a small room. There will be also flavours and chemistry that do not appear in the hybrid market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its origin of origin and the generation it has been reproduced from the first collection.
The Honest Exclusions
Nothing of the above turns regular seed into the right choice for everyone, and claiming that it is does the category no service.
A grower with space for three plants who wants each one of them to finish is far better off with feminized seed. The same is a grower unable to inspect the plants each day during the start of flower, since a late male in a small space ruins everything inside days. Someone running a single autoflower on a balcony gets no value 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 at some point to produce something new; for everyone else the regular shelf is best left where it is.
Ordering and the Law
Breeder Regular Seeds dispatches each order in unmarked packaging with the breeder’s packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, because 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 allowed under licence or neither is. Checking the position where you live is the buyer’s responsibility, and nothing of this article is legal advice.
