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 dwindling number of people who know exactly what they are looking for. It is easy to read that as the end of a technology. It is closer to the truth to see it as a library losing shelves while the bookshop next door grows. Every feminized line began as a regular one, every new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that survives at all survives only because someone held onto regular seed. Specialists 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 single plant. This article makes the argument for that unfashionable pack: what the male is for, what a buyer gives up by never growing one, and how to work with a population rather than a clone.
Not Just Pollen
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. To a breeder it is half the genome of every seed that follows, and that half is selected with the same care as the female.
A male contributes structure, vigour, maturation speed, tolerance to mould and pests, trichome production and the aromatic chemistry just as the female does; it just expresses some of those qualities less because it does not grows a smokable flower. Those who work with regular seed spend at least as much time choosing males as females, which is the effort that a feminized cross inherits and cannot replicate. Feminizing a female gives pollen; it cannot give a second set of selected genes.
How Diversity Leaks Away
Much of the feminized market is built from S1 seeds: a one famous clone, reversed and crossed with itself. Every round of that selfing cuts in half the remaining genetic diversity, and after two generations what remains is close to one plant repeated across marginally different ways.
That is fine for a consumer who needs that single plant. It is a problem for everyone downstream. Recessive faults surface: hermaphrodite tendencies, brittle stems, sensitivity to one particular mould. Traits that were present in the parent line but not in the selected clone vanish out of the gene pool entirely. A decade of such breeding leaves a market full with versions of the same few clones, and a anyone wanting to create something new discovers there is little remaining to cross. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and it can only exists as long as somebody grows it.
How to Judge a Male
Articles on selecting females are everywhere; guidance on picking males is scarce, since most people do not keep one long enough to look. For a grower making seed, these are the marks breeders look for.
- Timing. A male that declares sex early and flowers in step with the females is far more useful than a very early one that sheds pollen before the female is receptive.
- Restraint. Males that release huge amounts of pollen all at once are frequently also the less desirable genetically; many breeders favour moderate producers.
- Stability. A male that at the same time shows female flowers under ordinary stress is discarded without exception; that tendency is the last thing anyone wants carrying into a line.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a strong aroma indicates it holds the terpene genes worth passing on.
- Structure. Tight internodes, a strong central stem and branching that matches the intended female habit are passed on; a stretched, weak-stemmed male hands that down too.
Thinking in Numbers
A error first-time regular-seed buyers make is treating a pack as 10 chances at the same plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the point of running it is to see the range and choose from it.
About half the plants will be male, so a pack of 10 seeds yields around five females to compare and five males to cull or judge for breeding. Within the females, expect real variation: stature, finishing time, aroma, density, tolerance. This variation is not a failure in the seed; it is what the seed is for. The grower who keeps the best female and male now owns something a feminized pack can never offer: a line of chosen parents which are their own.
Making Your Own Seed
Owning selected parents is only worth something if making the next batch, and here the options open up. Three approaches cover most of what home breeders do.
- Backcross. Take a selected seedling back to one of its original parents to lock in a particular quality. It tightens the range fast and is useful when a single plant has something worth concentrating and the second contributed mainly vigour.
- Open pollination. Let every male pollinate each female. It preserves the full range of the line, produces a generous volume of seed, and involves no selection at all. This is how traditional lines are kept alive, and it is the correct method when the goal is preservation rather than improvement.
- Selected cross. One picked male to one or a few chosen females, everything else culled. The seeds carry the traits of two selected plants and express less variation than the original pack. Repeated over several rounds with consistent choices, this is how a new line is made.
All three require only a isolated space for the male, a paintbrush or a paper bag, and a few weeks. Not one of them calls for the chemical treatment that feminized seed-making does.
Keeping Old Lines Alive
A number of lines have never been feminized and likely never will be: landraces gathered from regions where cannabis was grown for centuries, and heirloom crosses from the early decades of indoor breeding. They are sold as regular seed because the people keeping them treat diversity as the entire value, and reversing a single plant would erase precisely what makes the line worth keeping.
Running a landrace from regular seed is different from growing a commercial hybrid. Expect large variation, long flowering times in equatorial lines, tall plants, and traits that make sense in a mountain valley but not under a small room. Expect also flavours and chemistry that do not exist in the hybrid market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, and each line labelled with its origin of collection and the generation it has been reproduced since the original collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed into the right option for everyone, and claiming otherwise does the category no service.
A grower with room for three plants who needs every one of them to finish is far better off with feminized seed. So is anyone unable to check the plants every day around the onset of flower, because a missed male in a confined space ruins everything within days. Someone running a single autoflower on a balcony has no value from a pack they cannot select from. And anyone who wants a known famous plant reproduced as closely as possible is looking for a feminized S1, not a two-parent 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 everyone else the back shelf is best ignored alone.
Before You Buy
Breeder Regular Seeds dispatches each order in unmarked parcels with the breeder’s packs intact inside and nothing on the exterior to indicate the contents. Orders to the United States are not accepted, because seed import is restricted there. Seed law varies widely by country: in a good number of places buying seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or neither is. Knowing the rules in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.
