Walk through most seed shops today and the regular section is the shelf at the back: smaller 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 the end of a technology. It is nearer to the truth to read it as a library shrinking while the bookshop next door expands. Every feminized line began as a regular one, each new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that exists at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article makes the argument for that half-male pack: what the male contributes, what a grower gives up by never seeing one, and how to work with a pack rather than a clone.
What a Male Plant Is Actually For
The lazy description of a male cannabis plant is «a pollen source», and to a flower grower that is the whole of it. For a breeder it is half the genome of every seed that follows, and half is chosen with the same attention as the female.
A male passes on structure, hybrid vigour, maturation speed, resistance to mould and pests, trichome production and the terpene profile exactly as the female does; it simply expresses several of those qualities less visibly because it never grows a smokable flower. Breeders who breed with regular seed invest at least as much time selecting males as females, which is the effort that a feminized line borrows and cannot repeat. Feminizing a female gives pollen; it does not give a second line of selected genes.
How Diversity Leaks Away
Much of the feminized market is made from S1 seeds: a one famous clone, treated and pollinated with itself. Each round of that selfing cuts in half the surviving genetic diversity, and after a couple of generations what is left is essentially one plant expressed across marginally different ways.
That is fine for a grower who wants that single plant. It is a problem for everyone downstream. Recessive faults surface: intersex tendencies, brittle stems, susceptibility to a particular mould. Traits that were present in the parent line but not in the selected clone disappear from the population altogether. A generation of this leaves a market full with variations of the same few plants, and a anyone trying to create something different finds there is little remaining to work with. Regular seed from a true outcrossed line is the reservoir that refills the market, and it only persist as long as somebody keep growing it.
How to Judge a Male
Guides on choosing females are easy to find; advice on picking males is scarce, since most growers never keep one long enough to look. For a grower making seed, the following are the marks breeders look for.
- Stability. Any male that at the same time shows female pistils under normal stress is discarded without exception; that trait is the last thing anyone wants carrying into a line.
- Timing. A male that shows sex early and matures at the same pace as the females is more useful than a very early one that releases pollen before the female is receptive.
- Restraint. Plants that dump enormous quantities of pollen all at once are frequently also the less selected in other respects; many breeders prefer steady producers.
- Resin on the stem. Rub a stem or a flower sac and smell it. A male with trichomes on its flower parts and a clear scent suggests it holds the resin genes that are worth passing on.
What 10 Seeds Actually Give You
The error first-time regular-seed buyers fall into is treating a pack as 10 chances 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 spread and choose from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields something like five females to evaluate and five males to either cull or assess for breeding. Among the females, look for noticeable variation: stature, flowering time, aroma, bud structure, resistance. That variation 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 supply: a pair of chosen parents which are theirs.
Making Your Own Seed
Owning chosen parents is only worth something if making the next batch, and here the options multiply. Three approaches account for most of what home breeders do.
- Backcross. Take a chosen offspring again to one of its original parents to lock in a particular quality. It tightens the genetics quickly and is used when one plant has something worth concentrating and the other contributed mostly vigour.
- Selected cross. One picked male to one or a few picked females, everything else removed. The offspring carry the traits of two specific plants and express narrower spread than the original pack. Done over several rounds with stable choices, this is how a new line is made.
- Open pollination. Let each male pollinate every female. It preserves the full diversity of the line, makes a large quantity of seed, and involves no selection at all. This is how traditional lines are kept alive, and it is the right approach when the aim is preservation rather than refinement.
Each of these need nothing more than a isolated space for the male, a soft brush or a paper bag, and a few weeks. None of them needs the chemical reversal that feminized seed-making does.
Keeping Old Lines Alive
A number of lines were never feminized and probably never will be: landraces collected from places where cannabis grew over centuries, and old crosses from the first decades of indoor breeding. They are sold as regular seed since the breeders maintaining them regard the population as the whole value, and reversing a single plant would erase precisely what makes the line worth preserving.
Running a landrace from regular seed is different from growing a modern hybrid. There will be large variation, long flowering times in equatorial lines, tall plants, and qualities that make sense in a mountain valley but not in a tent. Expect also aromas and effects that do not exist in the commercial market anywhere. Breeder Regular Seeds holds a dedicated landrace and heirloom section, and each line marked with its region of origin and the number of generations it has been reproduced from the first collection.
The Honest Exclusions
None of the above makes regular seed into the best option for everyone, and pretending otherwise does the category no service.
A grower with room for three plants who wants each one of them to finish is better served with feminized seed. The same is anyone who cannot afford to inspect the plants every day around the start of flower, since a late male in a confined space ruins everything inside days. A person running a single autoflower on a balcony gets no value from a population they cannot select from. And anyone who is after a known clone-only plant reproduced exactly is looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who intends to select, to keep and at some point to produce something new; for anyone else the back shelf is best ignored where it is.
Before You Buy
Breeder Regular Seeds dispatches each order in plain parcels with the original packs sealed inside and no on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law varies widely by country: in many places buying seeds is legal as collectables while germinating them is not, and in others both are allowed under licence or both is. Knowing the position in your own jurisdiction is the buyer’s job, and nothing of this article should be read as legal advice.
