Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced cheaper than the feminized packs next to it, and bought by a dwindling group of people who know exactly what they are looking for. It is easy to read that as obsolescence. It is closer to the truth to see it as a library shrinking while the bookshop next door expands. Every female-only line began as a regular one, each new cross requires a male somewhere in its history, and the diversity of cannabis genetics that survives at all survives because someone kept regular seed. Dedicated sellers 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 one plant. This article makes the case for that unfashionable pack: what the male contributes, what a buyer loses by never seeing one, and how to get value with a population rather than a copy.

What a Male Plant Is Actually For

The easy 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 that follows, and half is chosen with the same attention as the female.

A male contributes structure, hybrid vigour, maturation speed, tolerance to mould and pests, trichome production and the terpene profile exactly as the female does; it just expresses some of those qualities less because it does not produce a smokable flower. Those who work with regular seed invest at least as much time selecting males as females, which is the effort that a feminized line inherits and can never replicate. Feminizing a female yields pollen; it cannot provide a second set of selected genes.

How Diversity Leaks Away

A great deal of the feminized market is made from S1 seeds: a single famous clone, treated and crossed with itself. Every generation of that process cuts in half the surviving genetic diversity, and after two generations what is left is close to one plant expressed across slightly different forms.

That is acceptable for a consumer who wants that one plant. It is a problem for everyone downstream. Hidden faults surface: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Qualities that were present in the original line but not in the chosen clone disappear from the population altogether. A generation of this leaves a market full with versions of the same few clones, and a breeder wanting to create something new finds there is little remaining to work with. Regular seed from a true outcrossed line is the store that refills the pool, and it only exists if somebody keep growing it.

Selecting the Plant Nobody Writes About

Articles on selecting females are everywhere; guidance on picking males is rare, since most growers do not keep one past the first week of flower to look. For anyone producing seed, the following are the marks breeders look for.

• Stability. Any male that also shows female flowers under ordinary conditions is rejected outright; the trait is the one thing anyone wants carrying forward.
• Restraint. Plants that release enormous quantities of pollen early are frequently the least selected genetically; breeders favour moderate shedders.
• Structure. Short internodes, a strong central stem and branching that resembles the intended female habit are passed on; a lanky, weak-stemmed male passes that on too.
• Timing. A male that shows sex early and flowers at the same pace as the females is far more useful than a very early one that sheds pollen before any female is ready.
• Resin on the stem. Scratch a stem or a flower sac and smell it. A male with resin on its flower parts and a strong aroma suggests it holds the resin traits worth keeping.

A Pack Is a Population

A error first-time regular-seed growers fall into is treating a pack as 10 attempts at the one plant. It is nothing of the kind. A pack from a genuine outcrossed line is a slice of a population, and the point of running it is to see the spread and select 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 cull or assess for breeding. Within the females, expect noticeable differences: stature, finishing time, smell, bud structure, tolerance. This variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and male has something a feminized pack cannot offer: a line of selected parents which are their own.

From One Pack to the Next

Holding chosen parents is only worth something if producing the next generation, and there the choices open up. Three approaches cover most of what small-scale breeders do.

• Backcross. Take a selected offspring again to one of its parents to lock in a particular trait. It narrows the range quickly and is used when one plant has something worth keeping and the second brought mainly vigour.
• Selected cross. One chosen male to one or a few chosen females, everything else removed. The seeds inherit the traits of two selected plants and express less variation than the parent pack. Repeated over generations with stable choices, this is how a new line is made.
• Open pollination. Allow each male pollinate every female. It preserves the full range of the line, produces a generous quantity of seed, and involves no choosing at all. This is how landrace lines are maintained alive, and it is the correct method when the goal is preservation not refinement.

All three require only a isolated space for the male, a paintbrush or a paper bag, and a few weeks. None of them needs the chemical reversal that feminized seed-making requires.

The Seeds That Only Exist as Regulars

A number of lines have never feminized and likely never will be: landraces gathered from places where cannabis grew for centuries, and heirloom hybrids from the first decades of indoor breeding. They are sold as regular seed because the people maintaining them treat the population as the whole point, and selfing a single clone would destroy precisely what makes the line worth the trouble of keeping.

Growing a landrace from regular seed is different from growing a modern hybrid. There will be wide variation, extended flowering periods in tropical lines, tall plants, and qualities that made sense in a mountain valley but not in a tent. Expect too aromas and chemistry that do not appear in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its region of origin and the number of generations it has been reproduced from the original collection.

Who Should Not Buy Regular Seeds

None of the above makes regular seed the best option for everyone, and claiming otherwise would the category no favours.

A grower with room for a handful of plants who wants each one of them to finish is far better served with feminized seed. So is a grower who cannot afford to inspect the plants each day around the start of flower, since a missed male in a small space ruins the whole crop within days. Someone growing a single autoflower on a balcony gets no value from a population they cannot choose from. And a buyer who is after a known clone-only cut reproduced exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to hold onto and eventually to make something new; for everyone else the back shelf is safely left alone.

Before You Buy

Breeder Regular Seeds dispatches 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, because seed importation is restricted there. Seed law varies sharply by country: in many places owning seeds is legal as genetic preservation while germinating them is not, and in others the two are permitted under local rules or neither is. Knowing the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article should be read as legal advice.
