Walk through most seed shops today and the regular section is the shelf at the back: shorter every year, marked lower than the feminized packs beside it, and picked up by a dwindling number of people who understand exactly what they are after. It is tempting to read that as the end of a technology. It is closer to the truth to see it as a library shrinking while the bookshop next door grows. Every female-only line started as a regular one, every new cross requires a male at some point in its pedigree, and the diversity of cannabis genetics that exists at all exists because somebody kept regular seed. Specialists such as https://breederregularseeds.com carry lines going back 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 case for that half-male pack: what the male contributes, what a grower loses by not seeing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The easy account of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. To a breeder it is half the genome of every seed that follows, and half is selected with the same attention as the mother.
A male contributes growth habit, hybrid vigour, maturation speed, tolerance to mould and pests, trichome production and the terpene chemistry just as the female does; it simply expresses several of those qualities less visibly because it does not produce a smokable flower. Those who work with regular seed invest at least as much time selecting males as females, and this is the work that a feminized cross borrows 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
Much of the feminized catalogue is built from S1 seeds: a single popular clone, reversed and pollinated with itself. Every round of that process cuts in half the remaining genetic diversity, and after a couple of rounds what is left is essentially one plant repeated across marginally different ways.
That is fine for a grower who wants that single plant. It is a problem for everyone downstream. Hidden weaknesses emerge: intersex tendencies, weak stems, sensitivity to one particular mould. Traits that existed in the parent line but absent in the chosen clone disappear from the gene pool altogether. A generation of such breeding produces a market full with versions of a dozen clones, and a breeder trying to create something new finds there is little remaining to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the market, and it can only exists if people grows it.
How to Judge a Male
Articles on selecting females are everywhere; advice on choosing males is scarce, because most people do not keep one past the first week of flower to look. For anyone producing seed, the following are the signs breeders watch for.
- Timing. A male that declares sex early and flowers at the same pace as the females is far more useful than a very early one that sheds pollen before any female is receptive.
- Stability. Any male that at the same time shows female pistils under normal conditions is discarded without exception; the trait is the one thing anyone wants breeding forward.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong aroma suggests it carries the terpene traits that are worth passing on.
- Structure. Tight internodes, a strong central stem and a frame that matches the desired female shape are inherited; a stretched, weak-stemmed male passes that on too.
- Restraint. Plants that dump enormous quantities of pollen all at once are often the less desirable genetically; many breeders prefer steady producers.
Thinking in Numbers
The error first-time regular-seed buyers make is seeing 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 point of growing it is to see the range and select from it.
Roughly half the plants will be male, which means a pack of 10 seeds gives around five females to evaluate and five males to either discard or assess for breeding. Among the females, expect noticeable differences: stature, flowering time, smell, bud structure, resistance. That spread is not a flaw 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 cannot supply: a line of chosen parents which are their own.
Making Your Own Seed
Owning chosen parents is only worth something if making the next batch, and there the choices multiply. The main methods cover most of what home breeders attempt.
- Backcross. Take a selected seedling back to one of its parents to fix a specific quality. It narrows the range fast and is useful when a single parent shows something worth concentrating and the second contributed mostly vigour.
- Open pollination. Let every male pollinate every female. It keeps the full diversity of the line, produces a large quantity of seed, and does no selection at all. This is how traditional lines are kept alive, and it is the right method when the goal is preservation not improvement.
- Selected cross. One picked male on one or a few chosen females, every other plant else removed. The offspring carry the qualities of two specific plants and express less spread than the original pack. Done over several rounds with consistent selection, this is how a new line is built.
All three need only a separate space for the male, a paintbrush or a small bag, and a few weeks. Not one of them needs the chemical reversal that feminized seed-making does.
The Seeds That Only Exist as Regulars
A number of lines were never been feminized and likely never will be: landraces collected from regions where cannabis was grown over centuries, and old hybrids from the early decades of modern breeding. They are available as regular seed because the breeders maintaining them treat the population as the whole value, and reversing a single plant would erase exactly what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is a different experience from growing a modern hybrid. Expect large variation, extended flowering times in equatorial lines, tall plants, and traits that make sense in a mountain valley but not under a tent. Expect too flavours and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of collection and the generation it has been grown out from the original collection.
The Honest Exclusions
None of the above makes regular seed into the best choice for everyone, and pretending that it is would the product no favours.
A grower with room for three plants who wants every one of them to flower is better off with feminized seed. The same is anyone unable to inspect the plants each day around the start of flower, since a missed male in a confined space seeds everything inside days. Someone growing a single autoflower on a balcony has no value from a population they cannot select from. And a buyer who is after a specific famous plant reproduced as closely as possible is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to choose, to keep and eventually to produce something of their own; for anyone else the regular shelf is best left where it is.
Practicalities
Breeder Regular Seeds dispatches each order in unmarked parcels with the original packs intact inside and nothing on the outside to indicate the contents. Orders to the United States are not taken, because seed importation is restricted there. Seed law differs widely by country: in a good number of places owning seeds is legal as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Knowing the rules where you live is the buyer’s job, and nothing of this article should be read as legal advice.
