Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, priced cheaper than the feminized packs beside it, and picked up by a dwindling group of people who understand exactly what they are looking for. It is tempting to read that as obsolescence. It is nearer to the truth to read it as a library shrinking while the paperback rack next door grows. Every female-only line began as a regular one, each new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that survives at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article sets out the case for that half-male pack: what the male contributes, what a buyer loses by never growing one, and how to work with a population instead of a clone.

What a Male Plant Is Actually For

The lazy account 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 female.

A male passes on growth habit, vigour, flowering time, resistance to mould and pests, trichome density and the terpene profile exactly as the female does; it just shows some of those traits less visibly since it never produce a smokable flower. Those who breed with regular seed spend as much time choosing males as females, and this is the work that a feminized line inherits and cannot replicate. Reversing a female gives pollen; it does not give a different line of selected traits.

How Diversity Leaks Away

A great deal of the feminized market is built from S1 seeds: a one famous clone, treated and pollinated with itself. Each round of that selfing halves the remaining genetic diversity, and after a couple of generations what is left is essentially one plant repeated across marginally different ways.

That is acceptable for a grower who wants that single plant. It is a loss for everyone downstream. Hidden faults surface: intersex tendencies, brittle stems, sensitivity to one particular mould. Traits that existed in the original line but absent in the selected clone disappear out of the population entirely. A decade of this leaves a market crowded with versions of a dozen plants, and a anyone trying to create something new finds there is little remaining to cross. Regular seed from an outcrossed line is the store that replenishes the market, and it only exists if somebody grows it.

Selecting the Plant Nobody Writes About

Articles on selecting females are everywhere; guidance on choosing 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 look for.

• Restraint. Plants that dump huge amounts of pollen early are frequently the least selected genetically; many breeders prefer steady producers.
• Stability. Any male that at the same time forms female pistils under ordinary conditions is rejected without exception; that tendency is the last thing worth breeding forward.
• Timing. A male that shows sex early and matures in step with the females is far more workable than an early one that sheds pollen before the female is ready.
• Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with trichomes on its sepals and a clear scent suggests it carries the terpene genes worth keeping.

What 10 Seeds Actually Give You

The mistake first-time regular-seed buyers make is treating a pack as 10 chances 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 value of growing it is to observe the range and choose from it.

Roughly half the plants will be male, so 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, flowering time, aroma, density, tolerance. That variation is not a failure 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 can never offer: a line of chosen parents which are their own.

From One Pack to the Next

Holding selected parents means making the next batch, and here the options open up. The main approaches account for most of what small-scale breeders do.

• Selected cross. One chosen male on one or several chosen females, every other plant else culled. The seeds inherit the qualities of the two specific plants and express less variation than the original pack. Done over several rounds with consistent choices, this is how a stable line is built.
• Open pollination. Let each male reach each female. It preserves the full range 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 approach when the goal is preservation rather than refinement.
• Backcross. Cross a selected seedling back to one of its original parents to lock in a specific quality. It narrows the range fast and is used when one plant has something worth keeping and the second contributed mainly vigour.

Each of these require only a isolated space for the male, a paintbrush or a small bag, and a few weeks. Not one of them needs the chemical treatment that feminized production does.

Keeping Old Lines Alive

Some lines have never been feminized and likely never will be: landraces collected from places where cannabis was grown for centuries, and heirloom crosses from the first decades of indoor breeding. They are sold as regular seed because the people maintaining them treat the population as the entire 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. Expect wide variation, extended flowering times in equatorial lines, lanky plants, and traits that made sense in a mountain valley but not in a tent. Expect also aromas and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its origin of collection and the number of generations it has been reproduced from the original collection.

When the Library Is the Wrong Shop

Nothing of the above makes regular seed into the right choice for everyone, and claiming that it is does the category no favours.

A grower with room for three plants who wants every one of them to flower is better served with feminized seed. The same is anyone who cannot afford to inspect the plants each day around the onset of flower, since a missed male in a confined space seeds everything inside days. A person running a single autoflower on a balcony has no use from a pack they cannot select from. And a buyer who is after a known famous cut reproduced exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to choose, to keep and at some point to make something new; for everyone else the regular shelf is safely left alone.

Ordering and the Law

Breeder Regular Seeds dispatches each order in unmarked packaging with the breeder’s packs sealed inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law differs sharply by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others both are permitted under local rules or both is. Checking the position where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
