Why Breeders Still Buy Regular Seeds

Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced cheaper than the feminized packs beside it, and bought by a shrinking group of people who know exactly what they are after. It is easy to read that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the bookshop next door grows. Every feminized line started as a regular one, each new cross requires a male somewhere in its history, and the breadth of cannabis genetics that exists at all survives only because somebody kept regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a one plant. This article sets out the argument for that half-male pack: what the male contributes, what a grower gives up by not seeing one, and how to get value with a pack rather than a copy.

The Other Half of the Genome

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

A male contributes growth habit, hybrid vigour, maturation speed, tolerance to mould and pests, resin density and the aromatic profile exactly as the female does; it simply expresses several of those traits less visibly because it does not grows a finished flower. Breeders who work with regular seed invest as much time selecting males as females, and this is the effort that a feminized cross inherits and can never replicate. Reversing a female gives pollen; it does not give a second line of selected traits.

How Diversity Leaks Away

Much of the feminized catalogue is made from S1 seeds: a one famous clone, reversed and crossed with itself. Each generation of that process halves the surviving genetic variation, and after a couple of generations what remains is close to one plant repeated across slightly different forms.

This is acceptable for a grower who needs that one plant. It is a loss for everyone downstream. Hidden weaknesses emerge: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Traits that existed in the parent line but absent in the selected clone disappear from the gene pool entirely. A decade of this produces a market crowded with versions of a dozen clones, and a breeder trying to create something new finds there is little left to cross. Regular seed from a true outcrossed line is the store that refills the pool, and it only persist if people keep growing it.

Reading a Male Plant

Guides on selecting females are everywhere; advice on choosing males is scarce, since most people never keep one past the first week of flower to judge. For anyone making seed, these are the signs breeders watch for.

• Restraint. Males that dump huge amounts of pollen early are frequently the least selected in other respects; many breeders prefer moderate shedders.
• Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with resin on its sepals and a strong scent indicates it carries the terpene genes worth keeping.
• Timing. A male that declares sex early and flowers in step with the females is more useful than an early one that sheds pollen before the female is receptive.
• Stability. A male that at the same time shows female pistils under normal stress is rejected without exception; that trait is the one thing anyone wants carrying into a line.

A Pack Is a Population

A mistake first-time regular-seed buyers fall into is seeing a pack as 10 attempts at the one 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 see the spread and choose from it.

Roughly half the plants will be male, which means a pack of 10 seeds gives something like five females to compare and five males to discard or judge for breeding. Among the females, expect real differences: stature, finishing time, smell, bud structure, resistance. That spread is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and male now owns something a feminized pack cannot offer: a line of selected parents that are theirs.

Three Ways to Cross

Holding chosen parents means producing the next generation, and there the options multiply. The main methods account for most of what small-scale breeders attempt.

• Open pollination. Allow each male pollinate every female. It preserves the full range of the line, produces a generous quantity of seed, and does no selection at all. This is how landrace lines are kept alive, and it is the correct approach when the goal is preservation not improvement.
• Selected cross. One chosen male on one or several picked females, every other plant else removed. The offspring carry the qualities of two specific plants and show less spread than the original pack. Done over several rounds with consistent selection, this is how a new line is built.
• Backcross. Take a chosen seedling again to one of its parents to lock in a specific quality. It narrows the genetics quickly and is used when one parent shows something worth keeping and the second contributed mostly vigour.

All three need nothing more than a isolated space for the male, a paintbrush or a paper bag, and patience. None of them needs the chemical reversal that feminized seed-making requires.

Keeping Old Lines Alive

A number of lines were never been feminized and likely never will be: landraces collected from places where cannabis grew over centuries, and old hybrids from the first decades of modern breeding. They are available as regular seed because the people keeping them regard the population as the entire point, and selfing a single clone would erase precisely what makes the line worth keeping.

Growing a landrace from regular seed is a different experience from running a modern hybrid. There will be wide variation, long flowering periods in equatorial lines, tall plants, and traits that make sense in a mountain valley but not under a small room. Expect too aromas and effects that no longer exist in the commercial market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its origin of origin and the number of generations it has been reproduced from the original collection.

The Honest Exclusions

Nothing of the above turns regular seed the right option for everyone, and pretending that it is would the category no favours.

A grower with space for a handful of plants who needs every one of them to flower is better served with feminized seed. So is a grower unable to inspect the plants each day around the onset of flower, because a late male in a small space seeds everything inside days. Someone running a single autoflower on a balcony gets no use from a population they cannot select from. And anyone who wants a specific clone-only plant repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to hold onto and eventually to make something new; for everyone else the back shelf is safely left alone.

Practicalities

Breeder Regular Seeds sends every order in unmarked packaging with the original packs intact inside and no 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 genetic preservation while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the position in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
