Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced lower than the feminized packs next to it, and picked up by a dwindling group of people who understand exactly what they are looking for. 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 bookshop next door grows. Every female-only line started as a regular one, each new cross needs a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry 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 argument for that unfashionable pack: what the male is for, what a buyer gives up by not seeing one, and how to work with a pack rather than a copy.

Not Just Pollen

The lazy description of a male cannabis plant is “a pollen source”, and to 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 selected with the same care as the female.

A male passes on growth habit, hybrid vigour, maturation speed, resistance to mould and pests, trichome density and the terpene profile exactly as the female does; it just shows several of those traits less since it does not grows a smokable flower. Breeders who work with regular seed invest at least as much time selecting males as females, and this is the work that a feminized line borrows and can never replicate. Feminizing a female yields pollen; it cannot give a second line of selected genes.

What Happens When Lines Are Only Selfed

A great deal of the feminized catalogue is made from S1 seeds: a one popular clone, treated and pollinated with itself. Every generation of that process halves the surviving genetic variation, and after two rounds what remains is essentially one plant repeated across slightly different forms.

This is fine for a grower who needs that one plant. It is a problem for everyone downstream. Hidden weaknesses surface: hermaphrodite tendencies, brittle stems, sensitivity to a particular mould. Traits that existed in the parent line but absent in the chosen clone disappear out of the gene pool entirely. A decade of this produces a market full with variations of a dozen plants, and a breeder trying to create something different finds there is nothing remaining to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and that reservoir can only exists as long as people keep growing it.

Reading a Male Plant

Guides on choosing females are everywhere; guidance on picking males is rare, because most growers do not keep one long enough to look. For anyone producing seed, these are the signs breeders look for.

  • Timing. A male that declares sex early and flowers in step with the females is far more workable than an early one that sheds pollen before any female is receptive.
  • Restraint. Males that dump enormous amounts of pollen early are often the less selected in other respects; breeders prefer steady producers.
  • Structure. Tight internodes, a thick main stem and branching that matches the desired female shape are inherited; a stretched, weak-stemmed male hands that on too.
  • Stability. Any male that at the same time forms female pistils under ordinary conditions is rejected without exception; the tendency is the last thing worth carrying forward.

Thinking in Numbers

A mistake first-time regular-seed buyers make is seeing a pack as 10 chances at the one plant. It is the opposite. A pack from a real outcrossed line is a sample of a population, and the value of growing it is to see the spread and choose from it.

Roughly half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to discard or judge for breeding. Within the females, expect real variation: height, finishing time, aroma, density, resistance. That spread is not a failure in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male now owns something a feminized pack can never supply: a pair of chosen parents that are theirs.

Three Ways to Cross

Owning selected parents is only worth something if making the next batch, and there the options multiply. Three methods cover most of what home breeders attempt.

  • Backcross. Take a selected seedling again to one of its original parents to fix a specific trait. It narrows the range fast and is useful when one parent has something worth keeping and the other contributed mostly vigour.
  • Selected cross. One picked male to one or several chosen females, every other plant else removed. The offspring carry the qualities of the two specific plants and show less variation than the parent pack. Done over generations with stable choices, this is how a new line is made.
  • Open pollination. Let every male reach each female. It keeps the full range of the line, makes a generous quantity of seed, and does no selection at all. This is how landrace lines are maintained going, and it is the correct approach when the goal is preservation rather than improvement.

Each of these require only a separate space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical reversal that feminized production does.

The Seeds That Only Exist as Regulars

A number of lines were never feminized and likely never will be: landraces collected from regions where cannabis was grown over centuries, and old crosses from the first decades of modern breeding. They are available as regular seed since the breeders keeping them regard the population as the entire point, and selfing a single plant would erase precisely what makes the line worth preserving.

Running a landrace from regular seed is a different experience from growing a commercial hybrid. Expect large variation, extended flowering periods in equatorial lines, lanky plants, and qualities that made sense in a mountain valley but not under a tent. Expect also flavours and effects that do not 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 collection and the generation it has been grown out since the first collection.

The Honest Exclusions

None of the above makes regular seed the right choice for everyone, and pretending otherwise does the product no service.

A grower with room for a handful of plants who needs every one of them to flower is far better served with feminized seed. The same is a grower who cannot afford to inspect the plants each day around the start of flower, since a missed male in a confined space seeds everything within days. Someone running a single autoflower on a balcony has no use from a pack they cannot choose from. And anyone who is after a known famous cut reproduced exactly is better off 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 of their own; for anyone else the regular shelf is best left alone.

Before You Buy

Breeder Regular Seeds sends every order in unmarked packaging with the breeder’s packs sealed inside and no on the outside to reveal the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law varies widely by country: in many 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 position in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
