Regular Seeds: The Archive
Walk through most seed shops today and the regular section is a shelf at the back: shorter every year, marked cheaper than the feminized packs beside it, and bought by a dwindling group of people who know exactly what they are after. It is tempting to see that as obsolescence. It is closer to the truth to read it as a library losing shelves while the bookshop next door grows. Every feminized line started as a regular one, each new cross needs a male somewhere in its pedigree, and the diversity of cannabis genetics that survives at all exists because somebody held onto regular seed. Specialists such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds because a pack is intended to be a population, not a single plant. This article makes the case for that unfashionable pack: what the male contributes, what a grower gives up by not growing one, and how to work with a population instead of a copy.
Not Just Pollen
The easy account of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is all it. To 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 contributes structure, vigour, flowering speed, tolerance to mould and pests, trichome density and the aromatic chemistry just as the female does; it just expresses some of those qualities less visibly because it never grows a finished flower. Those who work with regular seed invest as much time selecting males as females, which is the work that a feminized line inherits and can never repeat. Reversing a female gives pollen; it does not give a second line of selected genes.
How Diversity Leaks Away
Much of the feminized market is built from S1 seeds: a one famous clone, treated and crossed with itself. Each round of that selfing cuts in half the surviving genetic variation, and after two rounds what is left is essentially one plant repeated in slightly different ways.
This is acceptable for a grower who wants that one plant. It is a problem for everyone who comes after. Hidden weaknesses surface: intersex tendencies, weak stems, sensitivity to one particular mould. Traits that existed in the parent line but absent in the selected clone vanish from the gene pool altogether. A generation of this leaves a market crowded with variations of the same few plants, and a breeder trying to create something new discovers there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the pool, and that reservoir can only persist as long as somebody keep growing it.
Selecting the Plant Nobody Writes About
Guides on choosing females are easy to find; guidance on picking males is scarce, since most growers do not keep one long enough to look. For anyone producing seed, the following are the marks breeders look for.
- Structure. Short internodes, a strong main stem and branching that resembles the intended female shape are passed on; a lanky, floppy male passes that down too.
- Timing. A male that declares sex early and flowers at the same pace as the females is far more useful than an early one that releases pollen before the female is receptive.
- Restraint. Males that release enormous amounts of pollen early are often the less desirable in other respects; breeders prefer steady shedders.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its sepals and a clear aroma suggests it holds the terpene traits that are worth keeping.
- Stability. A male that at the same time forms female flowers under ordinary conditions is discarded without exception; that trait is the last thing anyone wants breeding into a line.
What 10 Seeds Actually Give You
A error new regular-seed growers make is treating a pack as 10 chances at the one plant. It is the opposite. A pack from a real outcrossed line is a slice of a population, and the point of running it is to observe the range and choose from it.
Roughly half the plants will be male, which means a pack of 10 seeds yields around five females to evaluate and five males to either discard or assess for breeding. Among the females, expect noticeable differences: 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 can never supply: a pair of chosen parents that are theirs.
From One Pack to the Next
Owning selected parents is only worth something if producing the next generation, and there the options multiply. The main approaches account for most of what home breeders attempt.
- Selected cross. One chosen male to one or several chosen females, every other plant else removed. The offspring inherit the qualities of the two specific plants and show narrower spread than the original pack. Repeated over several rounds with stable selection, this is how a new line is built.
- Backcross. Cross a selected seedling back to one of its original parents to lock in a particular trait. It narrows the range quickly and is useful when a single parent shows something worth keeping and the second contributed mainly vigour.
- Open pollination. Let each male reach 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 kept going, and it is the correct approach when the goal is preservation not refinement.
All three require nothing more than a separate space for the male, a soft brush or a small bag, and patience. Not one of them calls for the chemical treatment that feminized production requires.
Landraces and Heirloom Lines
Some lines have never been feminized and probably never will be: landraces gathered from places where cannabis grew over centuries, and old crosses from the first decades of indoor breeding. They are sold as regular seed because the people keeping them treat diversity as the entire point, and selfing a single plant would erase exactly what makes the line worth preserving.
Growing a landrace from regular seed is a different experience from growing a commercial hybrid. Expect wide variation, extended flowering periods in equatorial lines, tall plants, and qualities that made sense in a field but not in a small room. Expect too aromas and chemistry that no longer appear in the hybrid market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line labelled with its origin of collection and the number of generations it has been grown out from the original collection.
When the Library Is the Wrong Shop
None of the above makes regular seed the right choice for everyone, and pretending that it is would the category no service.
A grower with room for three plants who wants each one of them to finish is far better served with feminized seed. So is a grower unable to check the plants each day during the onset of flower, since a late male in a small space ruins the whole crop inside days. Someone growing a single autoflower on a balcony has no use from a population they cannot select from. And a buyer who wants a known clone-only plant reproduced exactly 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 produce something new; for everyone else the regular shelf is safely ignored where it is.
Before You Buy
Breeder Regular Seeds dispatches every order in unmarked packaging with the original packs intact inside and nothing on the exterior to indicate the contents. Orders to the United States are not taken, because seed import is restricted there. Seed law differs widely by country: in many 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. Checking the rules where you live is the buyer’s job, and no part of this article is legal advice.
