Browse 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 bought by a shrinking number of people who understand exactly what they are after. It is tempting to see that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the paperback rack next door expands. 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 exists at all survives because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article sets out the argument for that half-male pack: what the male is for, what a grower gives up by never growing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is « a pollen source », and to a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and half is selected with the same attention as the mother.
A male contributes growth habit, vigour, maturation time, resistance to mould and pests, resin density and the aromatic chemistry exactly as the female does; it simply shows several of those qualities less visibly because it does not grows a smokable flower. Those who work with regular seed invest at least as much time selecting males as females, which is the work that a feminized line inherits and cannot replicate. Reversing a female gives pollen; it cannot give a second set of selected genes.
How Diversity Leaks Away
A great deal of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and crossed with itself. Each generation of that process cuts in half the remaining genetic variation, and after a couple of rounds what is left is essentially one plant expressed in marginally different forms.
That is fine for a grower who needs that single plant. It is a problem for everyone downstream. Recessive weaknesses surface: hermaphrodite tendencies, brittle stems, sensitivity to one particular mould. Traits that were present in the original line but not in the chosen clone vanish from the population entirely. A decade of this produces a market full with variations of a dozen clones, and a breeder wanting to create something different finds there is little left to cross. Regular seed from a true outcrossed line is the store that replenishes the pool, and that reservoir can only exists if people keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; advice on picking males is scarce, because most people do not keep one past the first week of flower to judge. For a grower making seed, these are the signs breeders watch for.
- Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with resin on its sepals and a strong aroma indicates it holds the resin traits that are worth passing on.
- Timing. A male that declares sex first and matures in step with the females is far more useful than a very early one that releases pollen before the female is receptive.
- Structure. Short internodes, a thick central stem and branching that resembles the intended female habit are inherited; a lanky, floppy male hands that down too.
- Stability. Any male that also shows female flowers under ordinary conditions is rejected outright; the trait is the one thing worth carrying forward.
A Pack Is a Population
A error first-time regular-seed buyers fall into is seeing a pack as 10 attempts at the one plant. It is the opposite. A pack from a real outcrossed line is a slice of a population, and the value of running it is to observe the spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives around five females to compare and five males to discard or judge for breeding. Among the females, expect real variation: height, flowering time, aroma, bud structure, resistance. That spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and the best male now owns something a feminized pack cannot offer: a pair of chosen parents that are theirs.
Making Your Own Seed
Holding selected parents is only worth something if producing the next batch, and here the choices multiply. The main methods cover most of what small-scale breeders do.
- Selected cross. One chosen male to one or a few picked females, every other plant else culled. The offspring carry the qualities of the two specific plants and show narrower spread than the original pack. Repeated over several rounds with stable selection, this is how a new line is made.
- Backcross. Cross a selected seedling again to one of its parents to fix a particular quality. It narrows the range fast and is useful when one plant has something worth concentrating and the second contributed mostly vigour.
- Open pollination. Allow every male reach every female. It preserves the whole diversity of the line, produces a generous volume of seed, and does no choosing at all. This is how landrace lines are maintained going, and it is the correct approach when the aim is preservation not refinement.
All three require only a isolated space for the male, a paintbrush or a small bag, and patience. None of them needs the chemical reversal that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines have never been feminized and likely never will be: landraces collected from regions where cannabis grew over centuries, and old hybrids from the early decades of indoor breeding. They are sold as regular seed because the breeders maintaining them regard the population as the whole point, and reversing a single clone would destroy exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from running a commercial hybrid. Expect wide variation, extended flowering times in equatorial lines, tall plants, and qualities that make sense in a mountain valley but not in a small room. Expect too aromas and effects that do not exist in the hybrid market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its region of collection and the generation it has been grown out since the original collection.
The Honest Exclusions
Nothing of the above makes regular seed the right choice for everyone, and pretending that it is would the product no service.
A grower with room for three plants who wants every one of them to flower is better off with feminized seed. The same is a grower unable to check the plants every day around the onset of flower, because a missed male in a small space seeds the whole crop inside days. A person growing a single autoflower on a balcony has no use from a population they cannot select 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 intends to choose, to hold onto and eventually to produce something of their own; for anyone else the back shelf is safely left where it is.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked parcels with the original packs intact inside and nothing on the exterior to indicate the contents. Orders to the United States are not accepted, as seed importation is not permitted there. Seed law varies widely by country: in a good number of places buying seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or both is. Knowing the rules where you live is the buyer’s responsibility, and nothing of this article should be read as legal advice.
