Browse through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower than the feminized packs beside it, and picked up by a shrinking number of people who understand exactly what they are looking for. It is tempting to see that as the end of a technology. It is nearer to the truth to read 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 requires a male at some point in its history, and the breadth of cannabis genetics that exists at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com stock lines that trace to the 1980s, sold in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article sets out the argument for that unfashionable pack: what the male is for, what a grower gives up by not seeing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is “a pollen source”, and to a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and half is selected with the same care as the mother.
A male passes on growth habit, hybrid vigour, flowering time, resistance to mould and pests, trichome production and the aromatic profile just as the female does; it simply shows several of those traits less visibly because it never produce a smokable flower. Those who breed with regular seed invest as much time choosing males as females, which is the effort that a feminized line inherits and can never repeat. Feminizing a female yields pollen; it cannot provide a different set of selected traits.
How Diversity Leaks Away
Much of the feminized catalogue is made from S1 seeds: a single popular clone, reversed and crossed with itself. Each round of that selfing halves the surviving genetic variation, and after two generations what remains is close to one plant expressed in slightly different ways.
That is fine for a grower who wants that one plant. It is a problem for everyone downstream. Recessive faults emerge: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Traits that were present in the original line but not in the chosen clone disappear from the population entirely. A decade of this leaves a market crowded with variations of a dozen plants, and a breeder trying to create something new finds there is nothing left to cross. Regular seed from a true outcrossed line is the reservoir that refills the pool, and it only persist as long as people keep growing it.
Selecting the Plant Nobody Writes About
Articles on selecting females are easy to find; guidance on choosing males is scarce, since most growers do not keep one past the first week of flower to judge. For a grower producing seed, the following are the marks breeders watch for.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with resin on its sepals and a strong aroma suggests it holds the resin genes that are worth keeping.
- Restraint. Males that dump enormous quantities of pollen all at once are often the least desirable genetically; many breeders prefer steady producers.
- Stability. Any male that also shows female pistils under ordinary conditions is discarded without exception; that tendency is the last thing worth carrying forward.
- Timing. A male that shows sex first and flowers in step with the females is more useful than a very early one that releases pollen before the female is receptive.
- Structure. Short internodes, a thick main stem and branching that matches the intended female shape are inherited; a stretched, floppy male hands that on too.
A Pack Is a Population
A error new regular-seed buyers fall into is seeing 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 see the spread and choose from it.
About half the plants will be male, so a pack of 10 seeds yields around five females to compare and five males to either cull or judge for breeding. Within the females, expect noticeable differences: stature, flowering time, smell, density, tolerance. This spread is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the best female and the best male now owns something a feminized pack can never supply: a line of selected parents which are their own.
From One Pack to the Next
Holding chosen parents means making the next generation, and here the options open up. The main methods cover most of what small-scale breeders attempt.
- Open pollination. Let every male reach each female. It keeps the whole diversity of the line, makes a generous volume of seed, and involves no selection at all. This is how landrace lines are kept alive, and it is the right method when the goal is preservation not improvement.
- Backcross. Take a chosen offspring back to one of its original parents to lock in a specific trait. It narrows the range fast and is useful when one parent has something worth keeping and the other brought mostly vigour.
- Selected cross. One chosen male to one or several picked females, everything else culled. The offspring inherit the qualities of the two specific plants and show narrower spread than the parent pack. Repeated over several rounds with consistent choices, this is how a new line is made.
Each of these require only a isolated space for the male, a paintbrush or a paper bag, and patience. Not one of them calls for the chemical reversal that feminized production does.
The Seeds That Only Exist as Regulars
Some lines have never been feminized and probably never will be: landraces gathered from regions where cannabis was grown over centuries, and heirloom crosses from the first decades of indoor breeding. They are sold as regular seed since the breeders maintaining them regard the population as the whole point, and reversing a single clone would destroy precisely what makes the line worth preserving.
Running a landrace from regular seed is different from growing a commercial hybrid. Expect wide variation, extended flowering periods in tropical lines, lanky plants, and traits that make sense in a mountain valley but not under a small room. There will be too aromas and effects that do not appear in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line marked with its origin of origin and the number of generations it has been reproduced from the first collection.
The Honest Exclusions
Nothing of the above makes regular seed the right choice for everyone, and claiming that it is does the product no service.
A grower with space for a handful of plants who wants each one of them to finish is better off with feminized seed. So is anyone who cannot afford to check the plants each day during the onset of flower, because a missed male in a small space ruins everything inside days. Someone growing a single autoflower on a balcony gets no value from a population they cannot select from. And anyone who wants a specific famous plant repeated as closely as possible 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 produce something new; for anyone else the regular shelf is safely left where it is.
Ordering and the Law
Breeder Regular Seeds sends each order in plain parcels with the original packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law varies widely by country: in many places buying seeds is legal as collectables while germinating them is not, and in others both are allowed under local rules or neither is. Checking the rules in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
