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 beside it, and picked up by a shrinking number of people who know exactly what they are after. It is easy to read that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the paperback rack next door expands. Every female-only line started as a regular one, every new cross needs a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all exists because someone kept regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article sets out the case for that half-male pack: what the male is for, what a grower loses by never seeing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The lazy account of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and that half is selected with the same care as the mother.
A male passes on structure, vigour, flowering time, tolerance to mould and pests, trichome production and the terpene chemistry just as the female does; it just expresses some of those qualities less because it never produce a finished flower. Breeders who work with regular seed invest at least as much time choosing males as females, and this is the effort that a feminized line inherits and can never repeat. Reversing a female gives pollen; it cannot provide a different set of selected genes.
The Narrowing
Much of the feminized market is built from S1 seeds: a one famous clone, reversed and crossed with itself. Each round of that process halves the surviving genetic variation, and after a couple of generations what is left is essentially one plant expressed across marginally different ways.
This is fine for a consumer who wants that one plant. It is a loss for everyone downstream. Recessive faults surface: intersex tendencies, brittle stems, susceptibility to a particular mould. Traits that were present in the parent line but not in the selected clone vanish from the population altogether. A decade of such breeding leaves a market crowded with variations of a dozen plants, and a breeder trying to create something different discovers there is little remaining to cross. Regular seed from an outcrossed line is the store that refills the market, and it can only exists as long as people grows it.
How to Judge a Male
Articles on choosing females are easy to find; advice on picking males is rare, because most growers never keep one past the first week of flower to look. For anyone making seed, these are the signs breeders watch for.
- Structure. Tight internodes, a strong central stem and a frame that matches the desired female habit are passed on; a stretched, weak-stemmed male hands that down too.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its sepals and a clear aroma suggests it carries the resin traits worth passing on.
- Stability. A male that at the same time shows female pistils under ordinary conditions is rejected outright; that tendency is the one thing anyone wants breeding into a line.
- Timing. A male that shows sex early and flowers at the same pace as the females is more useful than an early one that sheds pollen before the female is receptive.
Thinking in Numbers
The error new regular-seed buyers fall into is seeing a pack as 10 chances at the one plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the value of growing it is to observe the spread and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields around five females to compare and five males to cull or judge for breeding. Within the females, look for noticeable variation: height, flowering time, aroma, density, resistance. That variation is not a flaw in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and the best male now owns something a feminized pack cannot offer: a line of selected parents which are their own.
Three Ways to Cross
Holding chosen parents means making the next batch, and here the choices open up. The main approaches cover most of what home breeders attempt.
- Selected cross. One chosen male to one or several chosen females, everything else culled. The offspring inherit the traits of two selected plants and show less variation than the original pack. Repeated over several rounds with stable choices, this is how a new line is made.
- Open pollination. Allow each male pollinate each female. It preserves the whole range of the line, makes a large quantity of seed, and involves no choosing at all. This is how traditional lines are maintained going, and it is the right method when the aim is preservation rather than refinement.
- Backcross. Take a chosen seedling back to one of its parents to lock in a specific trait. It narrows the range fast and is used when one parent has something worth keeping and the second brought mostly vigour.
Each of these require nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. None of them needs the chemical reversal that feminized production requires.
Landraces and Heirloom Lines
Some lines were never feminized and likely never will be: landraces collected from regions where cannabis was grown over centuries, and old hybrids from the early decades of modern breeding. They are available as regular seed because the people keeping them treat the population as the whole point, and selfing a single plant would erase precisely what makes the line worth the trouble of preserving.
Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect large variation, long flowering periods in equatorial lines, lanky plants, and traits that make sense in a field but not in a tent. There will be also aromas and effects that do not appear in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its region of collection and the number of generations it has been grown out from the original collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed the best choice for everyone, and claiming that it is does the product no favours.
A grower with room for three plants who needs each one of them to flower is better served with feminized seed. So is anyone who cannot afford to check the plants each day around the start of flower, because a late male in a small space seeds 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 wants a known famous plant reproduced 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 hold onto and eventually to make something of their own; for anyone else the regular shelf is best ignored alone.
Ordering and the Law
Breeder Regular Seeds dispatches each order in plain parcels with the breeder’s packs sealed inside and nothing on the exterior to indicate the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law varies widely by country: in a good number of places buying seeds is lawful as collectables while germinating them is not, and in others both are permitted under licence or neither is. Checking the position where you live is the buyer’s job, and no part of this article is legal advice.
