Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced lower than the feminized packs next to it, and picked up by a shrinking number of people who understand exactly what they are after. It is easy to see that as obsolescence. It is closer to the truth to read it as a library losing shelves while the bookshop next door expands. Every feminized line began as a regular one, each new cross requires a male somewhere in its history, and the diversity of cannabis genetics that exists at all survives only because somebody held onto regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article makes the case for that unfashionable pack: what the male is for, what a buyer gives up by not seeing one, and how to work with a pack rather than a clone.
Not Just Pollen
The easy description of a male cannabis plant is “a pollen source”, and to 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 mother.
A male contributes structure, vigour, flowering time, resistance to mould and pests, resin density and the aromatic profile just as the female does; it just expresses several of those traits less visibly since it does not produce a finished flower. Breeders who breed with regular seed spend at least as much time selecting males as females, which is the work that a feminized cross borrows and can never repeat. Reversing a female gives pollen; it cannot give a second line of selected traits.
The Narrowing
A great deal of the feminized market is built from S1 seeds: a one famous clone, reversed and crossed with itself. Every generation of that process halves the remaining genetic variation, and after a couple of rounds what is left is close to one plant repeated across slightly different ways.
This is fine for a consumer who wants that one plant. It is a problem for everyone downstream. Hidden weaknesses emerge: intersex tendencies, brittle stems, sensitivity to a particular mould. Qualities that existed in the original line but absent in the selected clone vanish out of the population altogether. A generation of this produces a market full with variations of a dozen plants, and a anyone wanting to create something different finds there is little remaining 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; advice on choosing males is rare, because most growers never keep one past the first week of flower to look. For a grower making seed, the following are the marks breeders watch for.
- Restraint. Males that dump huge quantities of pollen all at once are frequently also the least selected genetically; many breeders prefer moderate shedders.
- Structure. Short internodes, a thick central stem and a frame that matches the desired female shape are inherited; a stretched, weak-stemmed male hands that on too.
- Stability. Any male that also shows female pistils under ordinary conditions is discarded without exception; that trait is the one thing anyone wants breeding into a line.
- Timing. A male that shows sex first and matures in step with the females is far more useful than a very early one that releases pollen before the female is ready.
A Pack Is a Population
A error new regular-seed buyers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a genuine outcrossed line is a slice of a population, and the value of growing it is to observe the range and select from it.
Roughly half the plants will be male, so a pack of 10 seeds yields around five females to evaluate and five males to either cull or judge for breeding. Within the females, look for noticeable variation: stature, finishing time, smell, density, tolerance. This spread is not a failure in the seed; it is what the seed is selling. The grower who takes cuttings from the best female and the best male has something a feminized pack can never offer: a line of selected parents which are their own.
From One Pack to the Next
Owning selected parents means making the next generation, and there the options open up. The main approaches cover most of what home breeders do.
- Open pollination. Let every male pollinate every female. It keeps the full diversity of the line, produces a large volume of seed, and involves no selection at all. This is how landrace lines are kept going, and it is the right method when the goal is preservation rather than improvement.
- Backcross. Take a selected offspring again to one of its original parents to fix a particular quality. It narrows the genetics fast and is useful when one plant has something worth concentrating and the second brought mainly vigour.
- Selected cross. One chosen male on one or a few picked females, every other plant else removed. The seeds inherit the qualities of two specific plants and express less variation than the original pack. Done over several rounds with stable choices, this is how a new line is made.
Each of these need nothing more than a separate space for the male, a soft brush or a small bag, and a few weeks. Not one of them calls for the chemical treatment that feminized production does.
Landraces and Heirloom Lines
A number of lines were never feminized and likely never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom hybrids from the first decades of indoor breeding. They are available as regular seed because the breeders keeping them treat diversity as the entire point, and selfing a single plant would destroy precisely what makes the line worth keeping.
Running a landrace from regular seed is different from growing a commercial hybrid. There will be wide variation, long flowering times in equatorial lines, lanky plants, and traits that make sense in a field but not in a small room. There will be too flavours and effects that do not appear in the hybrid market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its region of collection and the generation it has been reproduced from the original collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed into the best choice for everyone, and claiming otherwise does the category no favours.
A grower with space for a handful of plants who wants each one of them to finish is better served with feminized seed. So is a grower unable to check the plants every day during the onset of flower, since a missed male in a small space ruins the whole crop inside days. A person running a single autoflower on a balcony has no use from a pack they cannot select from. And a buyer who is after a specific clone-only 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 wants to choose, to hold onto and at some point to make something new; for anyone else the back shelf is best left where it is.
Practicalities
Breeder Regular Seeds sends each order in plain packaging with the original packs sealed inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, as seed importation is restricted there. Seed law differs sharply 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 both is. Knowing the rules where you live is the buyer’s job, and nothing of this article should be read as legal advice.
