Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, marked lower than the feminized packs next to it, and bought by a shrinking group of people who know exactly what they are after. It is easy to read that as obsolescence. It is closer 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 somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives only because someone kept regular seed. Specialists such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article sets out the case for that half-male pack: what the male contributes, what a grower loses by not seeing one, and how to work with a population rather than a clone.
The Other Half of the Genome
The easy description of a male cannabis plant is “a pollen source”, and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed which follows, and half is selected with the same attention as the mother.
A male passes on structure, hybrid vigour, maturation speed, resistance to mould and pests, resin density and the terpene chemistry just as the female does; it just shows several of those qualities less visibly because it never grows a finished flower. Breeders who breed with regular seed invest at least as much time selecting males as females, and this is the effort that a feminized line borrows and can never replicate. Feminizing a female yields pollen; it cannot provide a second line of selected genes.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is made from S1 seeds: a single famous clone, reversed and pollinated with itself. Each round of that process halves the remaining genetic variation, and after a couple of rounds what is left is close to one plant expressed across marginally different forms.
This is fine for a consumer who wants that one plant. It is a problem for everyone who comes after. Hidden faults surface: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Qualities that existed in the parent line but not in the selected clone vanish out of the gene pool entirely. A generation of this produces a market full with variations of a dozen clones, and a anyone trying to make something different discovers there is little remaining to work with. Regular seed from a true outcrossed line is the reservoir that refills the market, and that reservoir only exists as long as people grows it.
Selecting the Plant Nobody Writes About
Articles on selecting females are easy to find; advice on picking males is scarce, because most growers do not keep one past the first week of flower to look. For anyone producing seed, the following are the marks breeders look for.
- 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 any female is receptive.
- Stability. A male that at the same time forms female pistils under ordinary conditions is rejected outright; that tendency is the one thing anyone wants carrying forward.
- Structure. Tight internodes, a thick central stem and a frame that matches the desired female habit are passed on; a stretched, floppy male hands that down too.
- Restraint. Plants that dump huge quantities of pollen early are frequently the less selected in other respects; many breeders favour moderate shedders.
- Resin on the stem. Scratch a stem or a pollen sac and smell it. A male with trichomes on its sepals and a strong aroma indicates it carries the resin traits that are worth passing on.
Thinking in Numbers
The mistake new regular-seed growers make is treating a pack as 10 attempts at the one 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 observe the spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds yields around five females to evaluate and five males to cull or assess for breeding. Among the females, look for noticeable variation: stature, finishing time, smell, bud structure, resistance. This spread is not a failure in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male has something a feminized pack can never supply: 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 multiply. The main approaches cover most of what home breeders attempt.
- Backcross. Cross a chosen seedling again to one of its parents to fix a specific trait. It narrows the range fast and is used when a single parent shows something worth keeping and the second brought mainly vigour.
- Selected cross. One picked male on one or several picked females, every other plant else culled. The offspring carry the qualities of the two selected plants and show less variation than the original pack. Repeated over generations with stable choices, this is how a stable line is made.
- Open pollination. Let every male reach each female. It keeps the full diversity of the line, makes a large volume of seed, and involves no choosing at all. This is how landrace lines are kept alive, and it is the correct method when the goal is preservation rather than refinement.
All three require only a isolated space for the male, a paintbrush or a paper bag, and a few weeks. Not one of them needs the chemical treatment that feminized seed-making does.
The Seeds That Only Exist as Regulars
A number of lines have never feminized and likely never will be: landraces gathered from places where cannabis was grown over centuries, and old hybrids from the first decades of indoor breeding. They are sold as regular seed because the people maintaining them regard diversity as the entire value, and selfing a single plant would destroy precisely what makes the line worth the trouble of preserving.
Running a landrace from regular seed is a different experience from running a commercial hybrid. There will be wide variation, long flowering periods in tropical lines, tall plants, and traits that made sense in a mountain valley but not under a small room. Expect also aromas and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds holds a dedicated landrace and heirloom section, with each line labelled with its region of origin and the generation it has been grown out from the original collection.
The Honest Exclusions
None of the above makes regular seed into the right option for everyone, and pretending that it is does the category no service.
A grower with room for three plants who needs every one of them to finish is better off with feminized seed. So is anyone who cannot afford to inspect the plants each day around the onset of flower, since a missed male in a small space seeds the whole crop within days. Someone running a single autoflower on a balcony has no use from a population they cannot select from. And a buyer who is after a specific clone-only cut reproduced exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to choose, to hold onto and at some point to make something of their own; for anyone else the regular shelf is best left alone.
Ordering and the Law
Breeder Regular Seeds sends each order in unmarked packaging with the breeder’s packs sealed inside and no on the outside to indicate the contents. Orders to the United States are not accepted, as seed importation is restricted there. Seed law varies widely by country: in many places buying seeds is lawful as collectables while germinating them is not, and in others the two are allowed under licence or neither is. Checking the position in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.
