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 next to it, and picked up by a shrinking number of people who know exactly what they are looking for. It is easy to read that as obsolescence. It is closer to the truth to see it as a library shrinking while the bookshop next door grows. Every feminized line began as a regular one, each new cross needs a male somewhere in its pedigree, and the diversity of cannabis genetics that exists at all survives only because somebody 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 half-male pack: what the male contributes, what a grower gives up by never seeing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is „the one that makes pollen“, and for a flower grower that is the whole of it. For a breeder it is half the genome of every seed that follows, and half is chosen with the same care as the female.
A male passes on growth habit, vigour, maturation time, tolerance to mould and pests, trichome density and the terpene chemistry exactly as the female does; it just expresses some of those qualities less visibly because it does not produce a smokable flower. Those who breed with regular seed spend at least as much time choosing males as females, which is the effort that a feminized line inherits and cannot replicate. Feminizing a female yields pollen; it does not provide a second line of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one famous clone, reversed and pollinated with itself. Every round of that process cuts in half the remaining genetic diversity, and after a couple of generations what remains is essentially one plant repeated across slightly different forms.
This is acceptable for a grower who wants that single plant. It is a loss for everyone downstream. Hidden faults surface: hermaphrodite tendencies, brittle stems, susceptibility to a particular mould. Qualities that were present in the parent line but absent in the selected clone disappear from the gene pool altogether. A decade of this leaves a market full with variations of a dozen clones, and a breeder trying to create something different finds there is little remaining to work with. Regular seed from a true outcrossed line is the store that refills the market, and it can only exists if somebody grows it.
Reading a Male Plant
Guides on choosing females are everywhere; advice on picking males is scarce, since most people do not keep one past the first week of flower to judge. For a grower producing seed, the following are the marks breeders watch for.
- Restraint. Plants that release enormous amounts of pollen all at once are often also the less selected genetically; many breeders prefer steady producers.
- Timing. A male that declares sex first and flowers at the same pace as the females is more workable than an early one that sheds pollen before any female is receptive.
- Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a clear scent indicates it carries the resin genes that are worth passing on.
- Stability. A male that also shows female pistils under ordinary conditions is rejected outright; the tendency is the last thing worth breeding into a line.
A Pack Is a Population
The error first-time regular-seed buyers make is seeing a pack as 10 attempts at the same plant. It is nothing of the kind. 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 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 either discard or judge 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 the best male has something a feminized pack can never offer: a pair of chosen parents that are theirs.
From One Pack to the Next
Holding selected parents means producing the next generation, and there the options multiply. Three approaches account for most of what home breeders attempt.
- Selected cross. One picked male on one or several chosen females, everything else culled. The seeds inherit the traits of the two specific plants and express narrower variation than the original pack. Repeated over several rounds with consistent choices, this is how a new line is made.
- Open pollination. Let each male pollinate each female. It keeps the full range of the line, makes a large volume of seed, and does no selection at all. This is how traditional lines are maintained alive, and it is the right approach when the goal is preservation not refinement.
- Backcross. Take a chosen seedling again to one of its original parents to lock in a particular quality. It narrows the genetics fast and is used when one parent shows something worth keeping and the other brought mostly vigour.
Each of these require nothing more than a isolated space for the male, a paintbrush or a paper bag, and a few weeks. None of them calls for the chemical reversal that feminized production requires.
Keeping Old Lines Alive
Some lines were never feminized and probably never will be: landraces gathered from places where cannabis grew for centuries, and heirloom crosses from the first decades of modern breeding. They are available as regular seed since the breeders maintaining them regard the population as the whole value, and selfing a single plant would erase precisely what makes the line worth the trouble of keeping.
Running a landrace from regular seed is different from running a modern hybrid. Expect wide variation, long flowering times in tropical lines, tall plants, and traits that made sense in a mountain valley but not in a tent. There will be also aromas and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line marked with its origin of collection and the number of generations it has been reproduced from the original collection.
Who Should Not Buy Regular Seeds
Nothing of the above makes regular seed into the best choice for everyone, and pretending otherwise does the category no favours.
A grower with space for a handful of plants who wants each one of them to flower is better off with feminized seed. So is anyone unable to check the plants every day around the start of flower, since a late male in a confined space seeds the whole crop within days. A person growing a single autoflower on a balcony has no use from a population they cannot choose from. And anyone who wants a known clone-only cut repeated as closely as possible is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to keep and eventually to produce something new; for everyone else the regular shelf is best left where it is.
Before You Buy
Breeder Regular Seeds dispatches each order in unmarked parcels with the original packs sealed inside and no on the outside to reveal the contents. Orders to the United States are not accepted, as seed importation is restricted there. Seed law differs sharply by country: in many places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are permitted under licence or neither is. Checking the rules where you live is the buyer’s job, and no part of this article should be read as legal advice.
