Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, priced cheaper than the feminized packs next to it, and picked up by a shrinking group of people who know exactly what they are after. It is tempting to see that as obsolescence. It is closer to the truth to read it as a library shrinking while the bookshop next door expands. Every female-only line started as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all exists because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines going back to the 1980s, sold in packs of 10 seeds since a pack is meant to be a population, not a one plant. This article makes the case for that half-male pack: what the male is for, what a grower gives up by not seeing one, and how to get value with a population rather than a copy.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is all it. To a breeder it is half the genome of every seed that follows, and that half is chosen with the same attention as the mother.
A male contributes structure, vigour, flowering speed, tolerance to mould and pests, trichome production and the terpene chemistry just as the female does; it just shows several of those traits less visibly since it does not produce a smokable flower. Those who breed with regular seed invest at least as much time choosing males as females, which is the work that a feminized cross inherits and can never replicate. Feminizing a female yields pollen; it does not give a different line of selected traits.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one popular clone, treated and crossed with itself. Every round of that process cuts in half the remaining genetic diversity, and after two rounds what is left is essentially one plant repeated across slightly different ways.
That is fine for a grower who wants that single plant. It is a loss for everyone who comes after. Hidden weaknesses surface: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Qualities that were present in the parent line but absent in the selected clone disappear out of the population altogether. A decade of such breeding produces a market crowded with versions of a dozen clones, and a anyone wanting to make something new finds there is little remaining to work with. Regular seed from an 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
Articles on choosing females are easy to find; advice on picking males is rare, since most growers do not keep one past the first week of flower to judge. For a grower making seed, the following are the signs breeders watch for.
- Restraint. Plants that dump huge quantities of pollen early are often the least desirable in other respects; breeders prefer moderate producers.
- Timing. A male that declares sex first and matures in step with the females is far more workable than a very early one that sheds pollen before the female is ready.
- Resin on the stem. Scratch a stem or a flower sac and smell it. A male with resin on its sepals and a strong scent suggests it carries the terpene genes that are worth keeping.
- Stability. A male that also forms female pistils under normal stress is discarded outright; that tendency is the one thing worth breeding into a line.
What 10 Seeds Actually Give You
The mistake new regular-seed buyers fall into is treating a pack as 10 attempts at the same plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the value of growing it is to see the range and select from it.
About half the plants will be male, which means a pack of 10 seeds yields around five females to compare and five males to either cull or assess for breeding. Within the females, expect real variation: stature, finishing time, smell, bud structure, tolerance. That variation is not a failure in the seed; it is what the seed is for. The grower who keeps the best female and the best male now owns something a feminized pack cannot supply: a line of chosen parents that are their own.
From One Pack to the Next
Holding chosen parents means making the next generation, and there the options open up. The main approaches cover most of what small-scale breeders do.
- Selected cross. One picked male to one or several picked females, every other plant else removed. The offspring carry the traits of two specific plants and express narrower variation than the original pack. Repeated over generations with consistent selection, this is how a new line is made.
- Open pollination. Let every male pollinate each female. It keeps the whole diversity of the line, makes a large quantity of seed, and does no selection at all. This is how landrace lines are maintained going, and it is the right method when the goal is preservation rather than improvement.
- Backcross. Cross a selected offspring again to one of its original parents to lock in a specific trait. It tightens the genetics quickly and is useful when one plant has something worth concentrating and the other brought mainly vigour.
All three require only a separate space for the male, a soft brush or a paper bag, and a few weeks. Not one of them needs the chemical reversal that feminized production does.
Keeping Old Lines Alive
A number of lines were never feminized and likely never will be: landraces gathered from regions where cannabis grew over centuries, and old hybrids from the early decades of indoor breeding. They are available as regular seed because the people maintaining them regard diversity as the entire value, and reversing a single clone would destroy exactly what makes the line worth the trouble of keeping.
Running a landrace from regular seed is different from running a commercial hybrid. Expect wide variation, extended flowering times in tropical lines, tall plants, and qualities that make sense in a field but not in a tent. Expect also flavours and chemistry that no longer exist in the commercial market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its region of origin and the generation it has been grown out since the first collection.
When the Library Is the Wrong Shop
Nothing of the above makes regular seed into the best choice for everyone, and pretending that it is would the category no favours.
A grower with room for three plants who wants each one of them to finish is better served with feminized seed. The same is a grower unable to check the plants each day during the start of flower, since a late male in a small space ruins the whole crop within days. Someone running a single autoflower on a balcony has no use from a population they cannot select from. And anyone who wants a known famous cut 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 produce something new; for everyone else the regular shelf is best left where it is.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked parcels 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 differs widely by country: in a good number of places buying seeds is lawful as genetic preservation while germinating them is not, and in others both are allowed under local rules or neither is. Knowing the position where you live is the buyer’s responsibility, and nothing of this article is legal advice.
