Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, marked lower than the feminized packs next to it, and bought by a shrinking number of people who know exactly what they are after. It is easy 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 female-only line started as a regular one, each new cross needs a male somewhere in its pedigree, and the diversity of cannabis genetics that survives at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds because 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 is for, what a grower loses by never growing one, and how to get value with a pack instead of a clone.
Not Just Pollen
The lazy account 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 which follows, and half is chosen with the same attention as the mother.
A male contributes structure, hybrid vigour, maturation time, tolerance to mould and pests, resin density and the terpene chemistry exactly as the female does; it simply shows several of those qualities less visibly since it never produce a smokable flower. Those who breed with regular seed invest as much time selecting males as females, which is the effort that a feminized line inherits and can never replicate. Reversing a female yields pollen; it cannot provide a second set of selected traits.
How Diversity Leaks Away
Much of the feminized market is built from S1 seeds: a one famous clone, treated and crossed with itself. Every generation of that selfing cuts in half the remaining genetic variation, and after a couple of rounds what remains is close to one plant repeated across marginally different ways.
That is acceptable for a grower who needs that one plant. It is a problem for everyone downstream. Recessive weaknesses emerge: intersex tendencies, brittle stems, susceptibility to a particular mould. Qualities that were present in the parent line but absent in the selected clone vanish out of the gene pool altogether. A decade of this produces a market crowded with versions of a dozen plants, and a breeder trying to create something different discovers there is little left to cross. Regular seed from an outcrossed line is the reservoir that replenishes the market, and it can only exists if people keep growing it.
Reading a Male Plant
Articles on choosing females are easy to find; advice on choosing males is rare, since most growers do not keep one past the first week of flower to look. For anyone making seed, these are the signs breeders watch for.
- Stability. A male that also forms female flowers under normal stress is rejected without exception; the trait is the one thing anyone wants breeding into a line.
- Structure. Short internodes, a strong main stem and a frame that resembles the desired female shape are inherited; a stretched, floppy male hands that down too.
- Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a strong aroma suggests it holds the resin genes that are worth passing on.
- Restraint. Plants that dump huge quantities of pollen all at once are often also the least selected genetically; breeders prefer moderate shedders.
Thinking in Numbers
The mistake first-time regular-seed buyers make is treating a pack as 10 attempts at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the value of running it is to observe the range and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives something like five females to evaluate and five males to either discard or assess for breeding. Among the females, expect real variation: height, flowering time, aroma, density, resistance. That spread is not a failure in the seed; it is what the seed is selling. The grower who keeps the best female and the best male now owns something a feminized pack cannot offer: a line of selected parents that are their own.
Making Your Own Seed
Holding selected parents means producing the next batch, and here the options open up. Three approaches cover most of what small-scale breeders do.
- Selected cross. One chosen male on one or a few picked females, everything else removed. The offspring carry the qualities of the two selected plants and express narrower spread than the parent pack. Done over several rounds with stable choices, this is how a new line is built.
- Backcross. Take a selected offspring again to one of its parents to lock in a specific quality. It narrows the range fast and is used when one plant shows something worth keeping and the second contributed mainly vigour.
- Open pollination. Let each male reach every female. It keeps the whole diversity of the line, produces a large quantity of seed, and does no selection at all. This is how traditional lines are maintained alive, and it is the right method when the aim is preservation rather than improvement.
Each of these need nothing more than a separate space for the male, a soft brush or a small bag, and patience. None of them needs the chemical treatment that feminized seed-making requires.
Landraces and Heirloom Lines
Some lines have never feminized and probably never will be: landraces gathered from places where cannabis was grown for centuries, and old crosses from the first decades of modern breeding. They are sold as regular seed because the breeders keeping them treat the population as the entire value, and reversing a single clone would erase exactly what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is different from growing a modern hybrid. Expect large variation, extended flowering periods in equatorial lines, tall plants, and qualities that make sense in a field but not in a small room. There will be too aromas and effects that no longer exist in the hybrid market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line marked with its origin of collection and the generation it has been reproduced since the first collection.
When the Library Is the Wrong Shop
None of the above turns regular seed into the best option for everyone, and pretending otherwise does the product no favours.
A grower with room for three plants who wants every one of them to finish is far better served with feminized seed. The same is anyone who cannot afford to check the plants each day around the start of flower, because a late male in a confined space seeds the whole crop inside days. A person running a single autoflower on a balcony has no use from a population they cannot select from. And anyone who wants a known clone-only plant repeated as closely as possible is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to keep and eventually to make something of their own; for everyone else the regular shelf is best ignored alone.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked parcels with the original packs sealed inside and nothing on the outside to indicate the contents. Orders to the United States are not accepted, as seed import is restricted there. Seed law varies widely 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 allowed under licence or both is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and no part of this article should be read as legal advice.
