Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, priced lower than the feminized packs beside it, and picked up by a dwindling number of people who know exactly what they are after. It is easy to read that as the end of a technology. It is nearer to the truth to read it as a library losing shelves while the bookshop next door grows. Every feminized line started as a regular one, each new cross requires a male at some point 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 going back to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article makes the argument for that unfashionable pack: what the male is for, what a buyer loses by not seeing one, and how to get value with a pack rather than a copy.
What a Male Plant Is Actually For
The lazy account of a male cannabis plant is “the one that makes pollen”, 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 that half is selected with the same attention as the mother.
A male contributes structure, hybrid vigour, maturation speed, resistance to mould and pests, resin production and the aromatic profile exactly as the female does; it simply shows some of those qualities less since it does not grows a finished flower. Breeders who work with regular seed invest at least as much time selecting males as females, and this is the effort that a feminized cross borrows and cannot repeat. Reversing a female yields pollen; it does not provide a different set of selected genes.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is built from S1 seeds: a single popular clone, reversed and pollinated with itself. Each generation of that process halves the remaining genetic diversity, and after two rounds what is left is close to one plant expressed in marginally different ways.
This is acceptable for a consumer who wants that one plant. It is a problem for everyone who comes after. Hidden faults emerge: hermaphrodite tendencies, brittle stems, sensitivity to a particular mould. Qualities that existed in the original line but absent in the chosen clone disappear from the population altogether. A generation of such breeding produces a market crowded with variations of a dozen plants, and a breeder trying to create something different finds there is little remaining to cross. Regular seed from a true outcrossed line is the store that replenishes the pool, and that reservoir can only persist if people keep growing it.
Selecting the Plant Nobody Writes About
Guides on selecting females are easy to find; advice on choosing males is rare, since most growers do not keep one long enough to look. For a grower making seed, the following are the signs breeders look for.
- Structure. Tight internodes, a strong main stem and branching that resembles the intended female habit are passed on; a lanky, floppy male passes that down too.
- Timing. A male that shows 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.
- Restraint. Males that dump enormous amounts of pollen early are often the less desirable genetically; many breeders favour steady producers.
- Stability. Any male that also forms female flowers under normal conditions is discarded without exception; the tendency is the one thing worth carrying forward.
What 10 Seeds Actually Give You
A mistake first-time regular-seed buyers fall into is treating a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a slice 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 evaluate and five males to discard or assess for breeding. Among the females, look for real variation: stature, flowering time, aroma, bud structure, tolerance. This spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male has something a feminized pack cannot supply: a line of chosen parents that are their own.
Making Your Own Seed
Owning chosen parents is only worth something if making the next generation, and there the options multiply. The main methods cover most of what small-scale breeders attempt.
- Backcross. Take a selected seedling again to one of its parents to fix a specific trait. It tightens the range fast and is used when a single plant has something worth keeping and the other contributed mostly vigour.
- Open pollination. Allow each male reach every female. It keeps the whole range of the line, produces a large quantity of seed, and involves no choosing at all. This is how landrace lines are maintained going, and it is the correct approach when the goal is preservation rather than improvement.
- Selected cross. One chosen male on one or a few chosen females, every other plant else removed. The offspring carry the qualities of two selected plants and express less variation than the parent pack. Done over several rounds with consistent selection, this is how a stable line is built.
All three require nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. Not one of them calls for the chemical treatment that feminized production does.
Keeping Old Lines Alive
Some lines have never feminized and likely never will be: landraces collected from places where cannabis was grown over centuries, and heirloom hybrids from the early decades of indoor breeding. They are available as regular seed since the breeders keeping them treat the population as the entire value, and reversing a single plant would destroy precisely what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is different from running a commercial hybrid. There will be large variation, extended flowering periods in tropical lines, tall plants, and traits that make sense in a mountain valley but not in a small room. Expect too aromas and chemistry that no longer appear in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its origin of collection and the generation it has been reproduced since the original collection.
When the Library Is the Wrong Shop
Nothing of the above turns regular seed the best option for everyone, and claiming that it is does the product no service.
A grower with room for a handful of plants who wants every one of them to finish is better off with feminized seed. So is anyone unable to inspect the plants each day during the start of flower, because a late male in a small space seeds the whole crop within days. A person growing a single autoflower on a balcony has no use from a pack they cannot select from. And a buyer who wants a specific famous plant repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to hold onto and at some point to make something new; for anyone else the regular shelf is best left alone.
Practicalities
Breeder Regular Seeds sends every 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 taken, because seed importation is restricted there. Seed law varies sharply by country: in many places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are allowed under licence or neither is. Checking the rules where you live is the buyer’s job, and nothing of this article is legal advice.
