What Disappears When Every Seed Is Female

Walk through most seed shops today and the regular section is the 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 know exactly what they are after. It is tempting to see that as obsolescence. It is closer 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 somewhere in its history, and the diversity of cannabis genetics that survives at all exists 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 single plant. This article sets out the case for that unfashionable pack: what the male contributes, what a buyer gives up by never seeing one, and how to get value with a pack rather than a clone.

The Other Half of the Genome

The lazy account of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and that half is selected with the same attention as the female.

A male passes on growth habit, hybrid vigour, flowering speed, resistance to mould and pests, trichome production and the aromatic profile just as the female does; it just expresses several of those qualities less visibly because it never produce a finished flower. Those who work with regular seed spend at least as much time choosing males as females, which is the work that a feminized cross inherits and cannot repeat. Feminizing a female gives pollen; it cannot give a different set of selected genes.

The Narrowing

Much of the feminized catalogue is made from S1 seeds: a single famous clone, treated and crossed with itself. Each generation of that selfing cuts in half the surviving genetic diversity, and after two rounds what remains is close to one plant expressed across slightly different forms.

This is acceptable for a grower who needs that single plant. It is a loss for everyone downstream. Hidden faults emerge: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Qualities that existed in the parent line but not in the selected clone disappear from the population entirely. A decade of this produces a market crowded with versions of the same few clones, and a breeder trying to create something different discovers there is little remaining to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and it can only exists if people grows it.

How to Judge a Male

Articles on selecting females are everywhere; advice on picking males is rare, since most growers 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 enormous amounts of pollen early are frequently the less desirable genetically; many breeders prefer moderate shedders.
• Stability. A male that also forms female pistils under normal conditions is discarded without exception; the trait is the one thing anyone wants carrying forward.
• Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong scent suggests it holds the resin genes worth passing on.
• Structure. Tight internodes, a thick main stem and a frame that matches the intended female habit are passed on; a stretched, floppy male hands that on too.

Thinking in Numbers

The error new regular-seed buyers fall into is seeing a pack as 10 chances at the same plant. It is the opposite. A pack from a real outcrossed line is a sample of a population, and the value of growing it is to see the spread and select from it.

About half the plants will be male, so a pack of 10 seeds yields something like five females to evaluate and five males to either discard or assess for breeding. Among the females, look for real differences: stature, flowering time, aroma, bud structure, resistance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who takes cuttings from the best female and male has something a feminized pack can never supply: a pair of selected parents that are their own.

Making Your Own Seed

Owning selected parents means producing the next batch, and there the choices multiply. Three methods cover most of what home breeders do.

• Backcross. Take a chosen offspring again to one of its parents to fix a specific quality. It narrows the genetics fast and is used when a single plant shows something worth concentrating and the second brought mostly vigour.
• Open pollination. Let every male pollinate each female. It preserves the full diversity of the line, produces a generous quantity of seed, and does no selection at all. This is how traditional lines are kept going, and it is the right approach when the aim is preservation not refinement.
• Selected cross. One picked male on one or a few picked females, everything else culled. The seeds carry the qualities of the two selected plants and express less variation than the original pack. Done over several rounds with consistent selection, this is how a new line is built.

Each of these need only a isolated space for the male, a soft brush or a small bag, and a few weeks. None of them needs the chemical reversal that feminized production requires.

The Seeds That Only Exist as Regulars

Some lines were never feminized and probably never will be: landraces gathered from regions where cannabis grew over centuries, and old hybrids from the first decades of modern breeding. They are sold as regular seed because the people keeping them treat diversity as the whole point, and selfing a single plant would erase exactly what makes the line worth preserving.

Running a landrace from regular seed is a different experience from growing a commercial hybrid. Expect wide variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a field but not under a tent. Expect also aromas and chemistry that no longer exist in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of collection and the number of generations it has been reproduced from the original collection.

When the Library Is the Wrong Shop

None of the above turns regular seed the right choice for everyone, and claiming that it is would the product no service.

A grower with space for three plants who wants every one of them to flower is better served with feminized seed. The same is anyone unable to inspect the plants each day around the onset of flower, since a missed male in a small space seeds everything inside days. A person running a single autoflower on a balcony gets no value from a pack they cannot select from. And a buyer who is after a specific clone-only cut repeated exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to keep and eventually to produce something new; for everyone else the back shelf is safely left alone.

Ordering and the Law

Breeder Regular Seeds sends every order in unmarked packaging with the original packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed import is restricted there. Seed law differs sharply by country: in a good number of places owning seeds is lawful as collectables while germinating them is not, and in others both are allowed under local rules or neither is. Knowing the rules in your own jurisdiction is the buyer’s job, and no part of this article is legal advice.
