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 dwindling number of people who know exactly what they are after. It is easy to see that as the end of a technology. It is closer to the truth to see it as a library losing shelves while the bookshop next door grows. Every female-only line began as a regular one, every new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that exists at all exists because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock 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 makes the argument for that unfashionable pack: what the male contributes, what a buyer loses by not growing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The lazy account of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and that half is chosen with the same attention as the mother.
A male contributes structure, hybrid vigour, flowering speed, resistance to mould and pests, resin production and the terpene profile exactly as the female does; it just shows several of those traits less visibly since it does not produce a finished flower. Breeders who work with regular seed spend as much time selecting males as females, which is the effort that a feminized cross inherits and cannot repeat. Reversing a female gives pollen; it cannot give a second set of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is built from S1 seeds: a single famous clone, reversed and pollinated with itself. Each generation of that process cuts in half the surviving genetic diversity, and after a couple of rounds what remains is essentially one plant repeated across slightly different ways.
That is fine for a consumer who wants that single plant. It is a problem for everyone downstream. Hidden faults surface: hermaphrodite tendencies, brittle stems, susceptibility to one particular mould. Qualities that existed in the parent line but absent in the chosen clone vanish from the gene pool altogether. A decade of this leaves a market full with versions of a dozen clones, and a anyone trying to make something different finds there is little remaining to work with. Regular seed from a true outcrossed line is the reservoir that refills the pool, and that reservoir can only exists if somebody grows it.
Selecting the Plant Nobody Writes About
Guides on choosing females are easy to find; guidance on picking males is scarce, since most growers do not keep one past the first week of flower to look. For a grower making seed, these are the marks breeders look for.
- Stability. A male that also forms female flowers under normal conditions is rejected without exception; that trait is the last thing anyone wants breeding forward.
- Structure. Short internodes, a thick main stem and a frame that resembles the desired female shape are passed on; a stretched, weak-stemmed male hands that down too.
- Timing. A male that shows sex first and flowers at the same pace as the females is more useful than an early one that sheds pollen before any female is receptive.
- Restraint. Males that dump enormous amounts of pollen early are often the less desirable genetically; many breeders prefer moderate producers.
What 10 Seeds Actually Give You
A error new regular-seed growers fall into is treating a pack as 10 attempts 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, which means a pack of 10 seeds gives something like five females to evaluate and five males to cull or assess for breeding. Among the females, expect real differences: height, finishing time, aroma, bud structure, resistance. That spread is not a flaw 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 can never offer: a pair of chosen parents that are their own.
From One Pack to the Next
Owning chosen parents means making the next batch, and here the options open up. Three approaches account for most of what home breeders do.
- Open pollination. Allow every male pollinate each female. It keeps the full range of the line, makes a large quantity of seed, and involves no selection at all. This is how landrace lines are maintained alive, and it is the correct approach when the goal is preservation rather than refinement.
- Backcross. Take a selected seedling again to one of its parents to lock in a specific trait. It tightens the genetics fast and is used when one plant shows something worth concentrating and the second contributed mostly vigour.
- Selected cross. One chosen male on one or several chosen females, every other plant else removed. The offspring carry the traits of the two selected plants and express less spread than the original pack. Repeated over generations with stable choices, this is how a new line is made.
All three need only a isolated space for the male, a soft brush or a paper bag, and patience. Not one of them calls for the chemical treatment that feminized seed-making requires.
Landraces and Heirloom Lines
A number of lines were never feminized and probably never will be: landraces collected from places where cannabis grew for centuries, and heirloom crosses from the early decades of modern breeding. They are available as regular seed because the breeders maintaining them regard diversity as the whole point, and selfing a single clone would erase precisely what makes the line worth the trouble of keeping.
Running a landrace from regular seed is different from growing a commercial hybrid. Expect large variation, long flowering periods in tropical lines, lanky plants, and qualities that made sense in a mountain valley but not in 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, and each line marked with its region of origin and the number of generations it has been reproduced from the first collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed the right option for everyone, and pretending that it is would the product no service.
A grower with room for a handful of plants who needs every one of them to finish is far better served with feminized seed. The same is a grower who cannot afford to inspect the plants each day around the start of flower, because a late male in a small space seeds everything inside days. Someone growing a single autoflower on a balcony gets no value from a population they cannot choose from. And anyone who wants a specific clone-only plant repeated as closely as possible is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to select, to hold onto and eventually to make something new; for anyone else the back shelf is best left where it is.
Practicalities
Breeder Regular Seeds dispatches every order in plain packaging with the breeder’s packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed import is not permitted there. Seed law varies sharply by country: in a good number of places owning seeds is lawful as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Checking the position where you live is the buyer’s responsibility, and nothing of this article is legal advice.
