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 next to it, and picked up by a shrinking number of people who know exactly what they are looking for. It is tempting to read that as obsolescence. It is nearer to the truth to see it as a library shrinking while the bookshop next door expands. Every feminized line started as a regular one, each new cross requires a male somewhere in its history, and the diversity of cannabis genetics that survives at all exists because someone held onto regular seed. Specialists such as https://breederregularseeds.com stock 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 unfashionable pack: what the male contributes, what a grower loses by not seeing one, and how to work with a population 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 which follows, and that half is chosen with the same attention as the mother.
A male passes on growth habit, vigour, maturation speed, resistance to mould and pests, trichome density and the aromatic chemistry exactly as the female does; it just shows some of those qualities less visibly because it does not produce a smokable flower. Those who work with regular seed spend as much time selecting males as females, which is the effort that a feminized cross borrows and cannot replicate. Reversing a female yields pollen; it does not give a second line of selected genes.
The Narrowing
Much of the feminized market is made from S1 seeds: a single famous clone, reversed and pollinated with itself. Each generation of that process cuts in half the remaining genetic diversity, and after a couple of generations what is left is close to one plant repeated across marginally different forms.
This is fine for a consumer who needs that one plant. It is a problem for everyone who comes after. Hidden faults emerge: hermaphrodite tendencies, weak stems, sensitivity to one particular mould. Qualities that existed in the original line but not in the chosen clone disappear from the population entirely. A decade of such breeding produces a market full with versions of the same few plants, 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 store that replenishes the pool, and that reservoir can only persist if somebody keep growing it.
Reading a Male Plant
Articles on selecting females are everywhere; advice on picking males is scarce, because most growers never keep one long enough to look. For anyone making seed, the following are the marks breeders look for.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with resin on its sepals and a clear aroma indicates it holds the resin genes that are worth passing on.
- Timing. A male that shows sex early and flowers in step with the females is more useful than an early one that sheds pollen before the female is receptive.
- Stability. Any male that also forms female flowers under ordinary conditions is rejected outright; the trait is the one thing worth breeding forward.
- Restraint. Males that dump enormous amounts of pollen all at once are often the less desirable genetically; breeders favour steady shedders.
- Structure. Tight internodes, a thick main stem and a frame that resembles the intended female habit are inherited; a stretched, weak-stemmed male hands that on too.
A Pack Is a Population
A error new regular-seed buyers make is seeing a pack as 10 attempts at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the value of running it is to observe the range and choose from it.
About half the plants will be male, so a pack of 10 seeds yields something like five females to compare and five males to either cull or judge for breeding. Within the females, look for real variation: height, flowering time, smell, density, resistance. That spread is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the best female and male now owns something a feminized pack can never offer: a line of chosen parents that are theirs.
From One Pack to the Next
Owning selected parents means making the next batch, and here the options open up. Three approaches cover most of what small-scale breeders do.
- Selected cross. One picked male to one or several chosen females, everything else culled. The seeds inherit the traits of two specific plants and express narrower variation than the original pack. Repeated over generations with stable choices, this is how a new line is built.
- Backcross. Take a chosen seedling back to one of its parents to lock in a specific quality. It tightens the genetics quickly and is useful when a single parent has something worth concentrating and the other brought mostly vigour.
- Open pollination. Allow every male pollinate every female. It preserves the whole range of the line, produces a large volume of seed, and does no choosing at all. This is how landrace lines are kept alive, and it is the correct approach when the goal is preservation rather than improvement.
All three need only a separate space for the male, a soft brush or a small bag, and a few weeks. None of them needs the chemical reversal that feminized production requires.
Keeping Old Lines Alive
Some lines were never feminized and likely never will be: landraces gathered from places where cannabis was grown for centuries, and old hybrids from the early decades of modern breeding. They are sold as regular seed because the people maintaining them treat the population as the entire value, and selfing a single clone would erase exactly what makes the line worth keeping.
Running a landrace from regular seed is a different experience from running a commercial hybrid. There will be large variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a field but not in a small room. Expect also flavours and effects that do not exist in the commercial market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its origin of origin and the generation it has been reproduced from the original collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed the best option for everyone, and claiming otherwise does the category no favours.
A grower with space for a handful of plants who needs each one of them to finish is better off with feminized seed. So is anyone who cannot afford to check the plants every day around the onset of flower, since a late male in a confined space seeds the whole crop within days. Someone growing a single autoflower on a balcony has no use from a population they cannot choose from. And anyone who is after a specific clone-only cut reproduced as closely as possible is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to hold onto and eventually to make something of their own; for anyone else the back shelf is safely left alone.
Ordering and the Law
Breeder Regular Seeds dispatches each order in unmarked parcels with the breeder’s packs sealed inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is not permitted there. Seed law varies sharply by country: in many places owning seeds is lawful as collectables while germinating them is not, and in others both are permitted under local rules or both is. Checking the position in your own jurisdiction is the buyer’s job, and nothing of this article is legal advice.
