Browse 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 bought by a shrinking group of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is closer to the truth to see 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 needs a male somewhere in its history, and the diversity of cannabis genetics that exists at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds since a pack is meant to be a population, not a single plant. This article sets out the argument for that half-male pack: what the male is for, what a grower loses by not growing one, and how to work with a pack rather than a copy.
What a Male Plant Is Actually For
The lazy description 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 selected with the same care as the mother.
A male passes on structure, vigour, maturation time, resistance to mould and pests, resin production and the terpene profile exactly as the female does; it simply shows several of those traits less since it does not produce a finished flower. Those who work with regular seed invest at least as much time choosing males as females, and this is the effort that a feminized line borrows and can never replicate. Feminizing a female gives pollen; it cannot give a different line of selected traits.
What Happens When Lines Are Only Selfed
Much of the feminized market is made from S1 seeds: a one famous clone, treated and crossed with itself. Each round of that selfing halves the remaining genetic diversity, and after a couple of rounds what is left is essentially one plant repeated in slightly different ways.
That is acceptable for a consumer who wants that single plant. It is a loss for everyone downstream. Recessive weaknesses emerge: intersex tendencies, brittle stems, sensitivity to a particular mould. Traits that existed in the original line but not in the chosen clone disappear out of the population altogether. A generation of such breeding leaves a market crowded with variations of a dozen plants, and a anyone wanting to create something new discovers there is nothing remaining to cross. Regular seed from an outcrossed line is the store that refills the pool, and it only persist as long as people grows it.
Reading a Male Plant
Articles on choosing females are everywhere; advice on choosing males is scarce, because most people never keep one past the first week of flower to judge. For anyone making seed, these are the signs breeders look for.
- Structure. Tight internodes, a strong main stem and a frame that resembles the desired female shape are inherited; a stretched, weak-stemmed male hands that down too.
- Restraint. Plants that release enormous amounts of pollen early are frequently the less desirable genetically; many breeders favour moderate producers.
- Timing. A male that shows sex early and matures in step with the females is far more useful than a very early one that releases pollen before the female is ready.
- Stability. Any male that at the same time shows female flowers under normal conditions is discarded without exception; that tendency is the one thing anyone wants carrying forward.
- Resin on the stem. Rub a stem or a pollen cluster and smell it. A male with resin on its flower parts and a clear aroma suggests it holds the terpene genes worth keeping.
Thinking in Numbers
A error new regular-seed buyers fall into is seeing a pack as 10 attempts at the one 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.
Roughly half the plants will be male, which means a pack of 10 seeds gives something like five females to compare and five males to either discard or assess for breeding. Within the females, look for noticeable variation: height, finishing time, aroma, bud structure, resistance. That spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the best female and the best male now owns something a feminized pack can never offer: a line of selected parents that are their own.
From One Pack to the Next
Holding selected parents is only worth something if producing the next batch, and here the options open up. The main methods cover most of what small-scale breeders attempt.
- Backcross. Take a selected seedling again to one of its parents to lock in a particular quality. It tightens the genetics quickly and is useful when a single plant shows something worth concentrating and the second contributed mainly vigour.
- Selected cross. One chosen male on one or several picked females, everything else removed. The offspring inherit the traits of the two specific plants and express less variation than the original pack. Repeated over several rounds with stable choices, this is how a stable line is built.
- Open pollination. Let every male pollinate every female. It keeps the whole range of the line, produces a generous quantity of seed, and involves no choosing at all. This is how landrace lines are maintained going, and it is the correct approach when the goal is preservation not improvement.
Each of these require nothing more than a separate space for the male, a soft brush or a paper bag, and patience. Not one of them calls for the chemical treatment that feminized seed-making requires.
The Seeds That Only Exist as Regulars
Some lines have never been feminized and likely never will be: landraces gathered from places where cannabis was grown over centuries, and heirloom hybrids from the early decades of indoor breeding. They are sold as regular seed since the people maintaining them treat diversity as the entire value, and selfing a single plant would destroy exactly what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is a different experience from running a modern hybrid. Expect wide variation, long flowering times in tropical lines, lanky plants, and qualities that make sense in a field but not in a tent. Expect also aromas and chemistry that no longer appear in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of origin and the number of generations it has been grown out since the original collection.
When the Library Is the Wrong Shop
None of the above makes regular seed into the best choice for everyone, and claiming that it is does the category no service.
A grower with space for a handful of plants who needs every one of them to finish is far better off with feminized seed. So is a grower who cannot afford to check the plants each day around the onset of flower, because a missed male in a small space seeds the whole crop within days. Someone running a single autoflower on a balcony has no value from a pack they cannot select from. And a buyer who is after a specific clone-only plant reproduced as closely as possible is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to hold onto and eventually to produce something of their own; for everyone else the back shelf is safely ignored where it is.
Ordering and the Law
Breeder Regular Seeds dispatches each order in plain parcels with the original packs sealed inside and no on the outside to indicate the contents. Orders to the United States are not accepted, because seed import is not permitted there. Seed law varies widely by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others both are allowed under local rules or neither is. Knowing the rules in your own jurisdiction is the buyer’s job, and nothing of this article should be read as legal advice.
