Half Male, Fully Worth It: Regular Seeds

Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and picked up by a dwindling number of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is closer to the truth to read it as a library losing shelves while the bookshop next door expands. Every female-only line began as a regular one, every new cross requires a male at some point in its pedigree, and the diversity of cannabis genetics that exists at all exists because somebody held onto regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a single plant. This article makes the case for that unfashionable pack: what the male is for, what a grower loses by not growing one, and how to get value with a population instead of a clone.

The Other Half of the Genome

The easy description of a male cannabis plant is “the one that makes pollen”, 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 selected with the same care as the female.

A male contributes growth habit, vigour, flowering time, resistance to mould and pests, resin production and the terpene chemistry just as the female does; it simply shows some of those traits less since it does not produce a smokable flower. Breeders who work with regular seed invest at least as much time choosing males as females, which is the work that a feminized cross borrows and cannot repeat. Reversing a female gives pollen; it does not give a second set of selected traits.

How Diversity Leaks Away

Much of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and pollinated with itself. Each round of that process halves the surviving genetic variation, and after two generations what is left is essentially one plant repeated across slightly different ways.

This is acceptable for a consumer who wants that one plant. It is a loss for everyone downstream. Hidden weaknesses emerge: intersex tendencies, weak stems, sensitivity to one particular mould. Traits that were present in the parent line but not in the selected clone vanish out of the population entirely. A generation of this leaves a market crowded with versions of the same few clones, and a breeder wanting to create something different finds there is little left to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and that reservoir only exists as long as people grows it.

Reading a Male Plant

Articles on selecting females are everywhere; guidance on picking males is scarce, since most people never keep one long enough to judge. For anyone producing seed, the following are the marks breeders look for.

Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with resin on its flower parts and a strong aroma suggests it carries the terpene genes worth keeping.
Timing. A male that declares sex first and flowers in step with the females is far more useful than a very early one that sheds pollen before the female is receptive.
Structure. Short internodes, a strong central stem and branching that matches the desired female shape are inherited; a lanky, weak-stemmed male passes that down too.
Stability. A male that at the same time shows female flowers under ordinary conditions is discarded outright; the trait is the last thing worth carrying into a line.

A Pack Is a Population

A error first-time regular-seed growers fall into is treating a pack as 10 attempts 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.

Roughly half the plants will be male, so a pack of 10 seeds yields something like five females to compare and five males to either discard or judge for breeding. Among the females, expect noticeable differences: height, flowering time, smell, density, resistance. That spread is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the best female and the best male has something a feminized pack cannot offer: a pair of chosen parents which are theirs.

From One Pack to the Next

Owning selected parents is only worth something if making the next generation, and there the choices open up. The main methods cover most of what small-scale breeders do.

Open pollination. Allow each male reach every female. It keeps the full diversity of the line, makes a large volume of seed, and involves 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 refinement.
Backcross. Take a chosen seedling back to one of its parents to fix a particular quality. It tightens the range fast and is used when a single parent has something worth concentrating and the second brought mainly vigour.
Selected cross. One chosen male to one or a few picked females, every other plant else culled. The offspring carry the qualities of two specific plants and express narrower spread than the original pack. Repeated over several rounds with consistent selection, this is how a new line is built.

All three require only a separate space for the male, a soft brush or a paper bag, and patience. None of them calls for the chemical reversal that feminized production does.

Landraces and Heirloom Lines

Some lines were never been feminized and likely never will be: landraces gathered from regions where cannabis grew for centuries, and heirloom hybrids from the early decades of indoor breeding. They are sold as regular seed because the people maintaining them treat diversity as the whole value, and selfing a single plant would destroy precisely what makes the line worth preserving.

Running a landrace from regular seed is different from running a modern hybrid. Expect large variation, extended flowering times in equatorial lines, lanky plants, and qualities that made sense in a mountain valley but not under a tent. There will be also aromas and chemistry that no longer exist 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 generation it has been grown out since the original collection.

The Honest Exclusions

None of the above makes regular seed the right choice for everyone, and claiming that it is does the category no service.

A grower with room for a handful of plants who wants each one of them to flower is far better served with feminized seed. So is a grower unable to inspect the plants each day during the start of flower, because a late male in a small space seeds everything inside days. Someone growing a single autoflower on a balcony has no value from a population they cannot select from. And anyone who wants a known clone-only cut reproduced as closely as possible is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to hold onto and at some point to produce something of their own; for everyone else the regular shelf is best ignored alone.

Practicalities

Breeder Regular Seeds dispatches each order in unmarked parcels with the original packs intact inside and nothing on the outside to indicate the contents. Orders to the United States are not taken, as seed importation is restricted 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 the two are permitted under local rules or both is. Knowing the position where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
