Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, priced cheaper than the feminized packs beside it, and bought by a dwindling group of people who know exactly what they are looking for. It is easy to see that as obsolescence. It is nearer to the truth to see it as a library shrinking while the paperback rack next door grows. Every female-only line began as a regular one, each new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that exists at all survives because somebody kept regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article sets out the case for that half-male pack: what the male is for, what a buyer loses by never seeing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The lazy description of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and that half is chosen with the same care as the female.
A male contributes growth habit, hybrid vigour, maturation speed, resistance to mould and pests, trichome density and the aromatic chemistry just as the female does; it simply shows some of those traits less visibly since it never produce a finished flower. Breeders who work with regular seed spend as much time choosing males as females, and this is the work that a feminized cross borrows and can never replicate. Reversing a female gives pollen; it cannot give a different set of selected traits.
The Narrowing
Much of the feminized catalogue is built from S1 seeds: a single popular clone, reversed and pollinated with itself. Each round of that selfing cuts in half the surviving genetic variation, and after a couple of generations what is left is essentially one plant repeated across slightly different ways.
This is acceptable for a grower who wants that single plant. It is a problem for everyone who comes after. Recessive faults surface: intersex tendencies, weak stems, susceptibility to a particular mould. Qualities that existed in the parent line but not in the selected clone disappear from the population entirely. A generation of this leaves a market crowded with versions of the same few clones, and a anyone trying to create something new discovers there is nothing left to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and it only exists as long as people grows it.
Reading a Male Plant
Guides on selecting females are everywhere; guidance on picking males is rare, because most growers never keep one long enough to look. For a grower making seed, these are the marks breeders watch for.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its sepals and a strong scent suggests it carries the terpene genes that are worth passing on.
- Timing. A male that shows sex first and matures in step with the females is more useful than an early one that sheds pollen before any female is receptive.
- Structure. Tight internodes, a thick main stem and a frame that resembles the intended female shape are passed on; a lanky, weak-stemmed male passes that on too.
- Stability. Any male that at the same time forms female flowers under ordinary stress is discarded without exception; that trait is the one thing anyone wants carrying into a line.
What 10 Seeds Actually Give You
A error first-time 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 spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds gives around five females to compare and five males to cull or assess for breeding. Within the females, look for real variation: stature, finishing time, aroma, bud structure, resistance. This spread is not a flaw in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and male now owns something a feminized pack cannot supply: a pair of chosen parents which are their own.
Making Your Own Seed
Owning chosen parents means making the next batch, and here the choices multiply. Three approaches cover most of what home breeders do.
- Backcross. Take a selected offspring back to one of its parents to fix a particular quality. It tightens the genetics quickly and is useful when one plant shows something worth concentrating and the second brought mostly vigour.
- Open pollination. Let every male pollinate each female. It preserves the full diversity of the line, makes a large volume of seed, and does no selection at all. This is how traditional lines are maintained going, and it is the correct approach when the goal is preservation rather than improvement.
- Selected cross. One picked male to one or a few chosen females, every other plant else culled. The offspring inherit the traits of two specific plants and show narrower variation than the parent pack. Done over several rounds with consistent selection, this is how a new line is made.
All three require only a separate space for the male, a paintbrush or a small bag, and patience. None of them calls for the chemical treatment that feminized seed-making does.
The Seeds That Only Exist as Regulars
A number of lines were never feminized and likely never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom crosses from the early decades of indoor breeding. They are available as regular seed because the people keeping them regard the population as the entire point, and selfing a single clone would erase exactly what makes the line worth preserving.
Running a landrace from regular seed is different from growing a modern hybrid. Expect large variation, extended flowering times in tropical lines, tall plants, and qualities that made sense in a field but not under a tent. Expect too aromas and effects that no longer appear in the hybrid market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line labelled with its origin of origin and the generation it has been grown out from the first collection.
The Honest Exclusions
None of the above turns regular seed the best choice for everyone, and claiming that it is would the category no favours.
A grower with space for a handful of plants who needs each one of them to flower is better off with feminized seed. So is anyone who cannot afford to check the plants every day around the start of flower, because a late male in a confined space ruins the whole crop inside days. Someone running a single autoflower on a balcony has no value from a pack they cannot choose from. And a buyer who wants a specific 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 choose, to keep and eventually to produce something of their own; for everyone else the back shelf is best left alone.
Before You Buy
Breeder Regular Seeds dispatches every order in plain packaging with the breeder’s packs sealed inside and no on the outside to indicate the contents. Orders to the United States are not taken, as seed import is restricted there. Seed law varies sharply by country: in many places buying seeds is legal as collectables while germinating them is not, and in others the two are allowed under local rules or both is. Knowing the rules where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
