Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, priced cheaper than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are after. It is tempting to read that as the end of a technology. It is nearer to the truth to see it as a library losing shelves while the paperback rack next door grows. Every feminized line began as a regular one, every new cross needs a male at some point in its history, and the diversity of cannabis genetics that survives at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article makes the argument for that half-male pack: what the male is for, what a buyer gives up by never seeing one, and how to work with a pack rather than a clone.
The Other Half of the Genome
The lazy description of a male cannabis plant is “a pollen source”, and to a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and that half is chosen with the same care as the female.
A male passes on growth habit, vigour, flowering speed, resistance to mould and pests, resin production and the terpene chemistry exactly as the female does; it simply shows several of those qualities less since it never grows a smokable flower. Breeders who work with regular seed spend at least as much time choosing males as females, which is the effort that a feminized cross borrows and can never replicate. Reversing a female gives pollen; it does not provide a second line of selected traits.
The Narrowing
A great deal of the feminized catalogue is made from S1 seeds: a single popular clone, treated and crossed with itself. Each round of that process halves the surviving genetic diversity, and after a couple of generations what is left is close to one plant expressed across slightly different ways.
That is acceptable for a consumer who wants that one plant. It is a loss for everyone downstream. Recessive weaknesses emerge: hermaphrodite tendencies, weak stems, susceptibility to one particular mould. Traits that were present in the parent line but not in the chosen clone disappear from the gene pool entirely. A generation of such breeding produces a market crowded with versions of a dozen clones, and a anyone trying to create something different finds there is nothing remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and that reservoir only exists as long as people keep growing it.
How to Judge a Male
Articles on selecting 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 anyone producing seed, these are the signs breeders watch for.
- Stability. Any male that at the same time shows female flowers under ordinary stress is rejected outright; that tendency is the last thing anyone wants breeding forward.
- Timing. A male that declares sex first and flowers at the same pace as the females is far more useful than an early one that sheds pollen before any female is receptive.
- Restraint. Males that dump enormous amounts of pollen early are often also the less selected in other respects; breeders prefer steady shedders.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a clear aroma indicates it holds the resin genes worth passing on.
- Structure. Short internodes, a strong central stem and a frame that matches the intended female habit are passed on; a stretched, weak-stemmed male passes that down too.
Thinking in Numbers
The mistake new regular-seed buyers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the point of growing it is to observe the spread 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. Among the females, expect real differences: stature, flowering time, aroma, bud structure, resistance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who keeps the best female and male has something a feminized pack cannot offer: a pair of selected parents which are their own.
From One Pack to the Next
Owning chosen parents means producing the next batch, and here the choices multiply. Three methods cover most of what small-scale breeders do.
- Backcross. Cross 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 a single parent has something worth concentrating and the second brought mostly vigour.
- Selected cross. One picked male on one or several chosen females, every other plant else culled. The seeds carry the traits of two specific plants and express less variation than the original pack. Done over generations with consistent choices, this is how a new line is made.
- Open pollination. Allow every male reach each female. It preserves the whole range of the line, makes a large quantity of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the right method when the aim is preservation rather than improvement.
Each of these require only a separate space for the male, a soft brush or a small bag, and patience. None of them needs the chemical treatment that feminized production does.
The Seeds That Only Exist as Regulars
Some lines have never feminized and likely never will be: landraces collected from regions where cannabis grew over centuries, and old crosses from the first decades of indoor breeding. They are sold as regular seed because the breeders keeping them regard diversity as the whole value, and reversing a single plant would erase precisely what makes the line worth preserving.
Running a landrace from regular seed is different from growing a modern hybrid. There will be large variation, extended flowering times in equatorial lines, lanky plants, and traits that make sense in a field but not in a tent. There will be also flavours and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its region of origin and the number of generations it has been grown out since the original collection.
The Honest Exclusions
Nothing of the above makes regular seed the right choice for everyone, and claiming otherwise would the category no favours.
A grower with room for a handful of plants who needs every one of them to finish is better off with feminized seed. So is anyone unable to check the plants each day during the onset of flower, because a late male in a small space ruins everything within days. Someone growing a single autoflower on a balcony gets no use from a pack they cannot choose from. And a buyer who is after a known clone-only plant repeated exactly is better off 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 make something of their own; for anyone else the regular shelf is best ignored alone.
Before You Buy
Breeder Regular Seeds sends each order in plain parcels with the original packs intact inside and nothing on the outside to reveal the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law varies sharply by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or neither is. Checking the rules in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
