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 understand exactly what they are looking for. It is tempting to read that as obsolescence. It is closer to the truth to read it as a library losing shelves while the bookshop next door expands. Every female-only line started as a regular one, every new cross needs a male somewhere in its history, and the diversity of cannabis genetics that survives at all survives because someone kept 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 meant to be a population, not a single plant. This article sets out the case for that unfashionable pack: what the male contributes, what a grower loses by never seeing one, and how to get value with a pack rather than a clone.
Not Just Pollen
The lazy description of a male cannabis plant is “the one that makes pollen”, 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 care as the female.
A male contributes growth habit, vigour, maturation time, tolerance to mould and pests, resin density and the aromatic profile exactly as the female does; it simply shows several of those traits less visibly since it never grows a smokable flower. Those who work with regular seed spend as much time choosing males as females, which is the effort that a feminized line borrows and can never replicate. Feminizing a female yields pollen; it does not provide a different line of selected traits.
The Narrowing
A great deal of the feminized market is made from S1 seeds: a single famous clone, reversed and pollinated with itself. Each generation of that selfing cuts in half the surviving genetic variation, and after two generations what remains is close to one plant expressed across marginally different ways.
That is fine for a consumer who needs that single plant. It is a problem for everyone who comes after. Recessive faults emerge: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Qualities that existed in the original line but absent in the chosen clone vanish out of the gene pool altogether. A generation of such breeding produces a market crowded with variations of the same few plants, and a breeder trying to make something different discovers there is nothing left to cross. Regular seed from an outcrossed line is the store that refills the pool, and it can only persist as long as somebody grows it.
How to Judge a Male
Articles on choosing females are easy to find; advice on choosing males is scarce, because most people never keep one long enough to judge. For a grower making seed, these are the signs breeders look for.
- Timing. A male that declares sex early and flowers at the same pace as the females is far more workable than a very early one that releases pollen before the female is receptive.
- Stability. Any male that also shows female pistils under ordinary stress is discarded outright; the tendency is the last thing worth carrying forward.
- Structure. Short internodes, a strong main stem and branching that resembles the intended female habit are passed on; a stretched, weak-stemmed male hands that on too.
- Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong aroma suggests it carries the resin traits that are worth keeping.
- Restraint. Males that dump huge amounts of pollen all at once are often the least selected in other respects; breeders prefer steady producers.
What 10 Seeds Actually Give You
A mistake new regular-seed buyers make is treating a pack as 10 attempts at the same plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the point of running 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 evaluate and five males to either cull or judge for breeding. Among the females, look for noticeable variation: stature, finishing time, smell, density, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male has something a feminized pack cannot offer: a pair of selected parents that are their own.
From One Pack to the Next
Owning chosen parents means producing the next batch, and here the options open up. The main approaches account for most of what home breeders do.
- Backcross. Take a chosen seedling again to one of its parents to lock in a particular trait. It narrows the genetics fast and is used when one plant shows something worth concentrating and the other contributed mostly vigour.
- Open pollination. Allow every male pollinate every female. It preserves the full diversity of the line, produces a generous quantity of seed, and involves no selection at all. This is how landrace lines are maintained alive, and it is the right method when the goal is preservation rather than refinement.
- Selected cross. One picked male to one or a few chosen females, every other plant else removed. The offspring carry the traits of the two specific plants and show narrower spread than the parent pack. Done over several rounds with consistent selection, this is how a stable line is built.
Each of these require nothing more than a separate space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical reversal that feminized seed-making requires.
Landraces and Heirloom Lines
Some lines have never feminized and probably never will be: landraces collected from regions where cannabis grew over centuries, and heirloom hybrids from the first decades of indoor breeding. They are sold as regular seed because the breeders keeping them treat the population as the whole value, and selfing a single plant would erase precisely what makes the line worth keeping.
Running a landrace from regular seed is a different experience from running a modern hybrid. There will be wide variation, long flowering times in tropical lines, tall plants, and traits that made sense in a field but not in a small room. Expect too flavours and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line marked with its origin of collection and the generation it has been grown out since the original collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed into the best choice for everyone, and pretending otherwise does the category no service.
A grower with room for three plants who wants every one of them to flower is far better served with feminized seed. So is anyone unable to check the plants every day during the start of flower, since a late male in a small space seeds the whole crop within days. A person running a single autoflower on a balcony gets no value from a population they cannot choose from. And a buyer who wants a known clone-only 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 produce something of their own; for everyone else the regular shelf is best left where it is.
Practicalities
Breeder Regular Seeds sends every order in plain parcels with the original packs sealed inside and nothing on the outside to reveal the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law varies widely by country: in a good number of places owning seeds is lawful as collectables 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 no part of this article is legal advice.
