Browse through most seed shops today and the regular section is a shelf at the back: shorter every year, marked lower than the feminized packs next to it, and bought by a dwindling group of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is nearer to the truth to see it as a library shrinking while the bookshop next door expands. Every female-only line started as a regular one, each new cross requires a male somewhere in its history, and the breadth of cannabis genetics that survives at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article makes the case for that half-male pack: what the male contributes, what a buyer loses by never seeing one, and how to work with a pack instead of a clone.
Not Just Pollen
The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is all it. For a breeder it is half the genome of every seed that follows, and that half is chosen with the same care as the mother.
A male contributes growth habit, hybrid vigour, flowering speed, resistance to mould and pests, resin production and the aromatic profile exactly as the female does; it simply expresses several of those qualities less visibly since it does not produce a smokable flower. Breeders who breed with regular seed spend as much time choosing males as females, which is the effort that a feminized line borrows and can never repeat. Feminizing a female yields pollen; it cannot provide a second set of selected genes.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a one popular clone, treated and pollinated with itself. Every round of that process halves the surviving genetic diversity, and after two generations what remains is close to one plant expressed in marginally different ways.
That is fine for a grower who needs that one plant. It is a problem for everyone who comes after. Recessive weaknesses emerge: intersex tendencies, weak stems, susceptibility to a particular mould. Traits that were present in the parent line but absent in the chosen clone vanish out of the population altogether. A generation of this leaves a market crowded with versions of the same few clones, and a breeder trying to make something different finds there is little left to cross. Regular seed from an outcrossed line is the reservoir that replenishes the pool, and it can only persist as long as people grows it.
How to Judge a Male
Guides on choosing females are easy to find; guidance on choosing males is scarce, since most people never keep one long enough to look. For a grower producing seed, the following are the signs breeders watch for.
- Timing. A male that shows sex early and matures at the same pace as the females is more useful than a very early one that releases pollen before the female is ready.
- Structure. Short internodes, a strong main stem and a frame that matches the desired female habit are passed on; a stretched, weak-stemmed male hands that on too.
- Stability. A male that also shows female pistils under normal conditions is discarded outright; the tendency is the one thing anyone wants breeding into a line.
- Restraint. Plants that release enormous amounts of pollen early are often the least desirable genetically; many breeders prefer moderate shedders.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its flower parts and a clear aroma indicates it holds the terpene traits that are worth keeping.
A Pack Is a Population
The error first-time regular-seed growers fall into is treating a pack as 10 attempts 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 growing it is to see the range 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 either discard or assess for breeding. Among the females, expect real differences: stature, flowering time, smell, density, resistance. This variation is not a flaw 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 selected parents that are theirs.
Three Ways to Cross
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 attempt.
- Selected cross. One chosen male on one or a few chosen females, every other plant else culled. The offspring carry the traits of the two specific plants and show narrower variation than the original pack. Repeated over several rounds with consistent selection, this is how a stable line is made.
- Open pollination. Let each male reach each female. It preserves the whole range of the line, makes a generous volume of seed, and involves no selection at all. This is how traditional lines are maintained alive, and it is the correct approach when the aim is preservation rather than refinement.
- Backcross. Cross a selected seedling again to one of its parents to lock in a specific quality. It tightens the range quickly and is used when one plant shows something worth concentrating and the other contributed mostly vigour.
All three need nothing more than a separate space for the male, a paintbrush or a paper bag, and patience. Not one of them needs the chemical reversal that feminized seed-making does.
The Seeds That Only Exist as Regulars
Some lines were never feminized and probably never will be: landraces gathered from regions where cannabis was grown over centuries, and old hybrids from the first decades of indoor breeding. They are available as regular seed since the breeders keeping them treat diversity as the entire value, and reversing a single plant would destroy precisely what makes the line worth keeping.
Growing a landrace from regular seed is different from running a modern hybrid. Expect wide variation, long flowering periods in equatorial lines, lanky plants, and qualities that make sense in a mountain valley but not in a tent. There will be also flavours and chemistry that do not exist in the commercial market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its region of collection and the number of generations it has been reproduced from the original collection.
The Honest Exclusions
Nothing of the above makes regular seed into the right option for everyone, and claiming otherwise does the category no favours.
A grower with space for three plants who needs every one of them to flower is better served with feminized seed. So is anyone who cannot afford to check the plants each day during the start of flower, because a late male in a small space ruins everything within days. A person growing a single autoflower on a balcony gets no use from a pack they cannot select from. And anyone who wants a known famous cut repeated 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 select, to hold onto and eventually to produce something of their own; for anyone else the regular shelf is best ignored alone.
Before You Buy
Breeder Regular Seeds sends each order in unmarked parcels with the breeder’s packs intact inside and no on the outside 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 owning seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or both is. Knowing the rules in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
