Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, priced cheaper than the feminized packs next to it, and bought by a shrinking group of people who know exactly what they are after. It is tempting to see that as the end of a technology. It is closer to the truth to read it as a library losing shelves while the paperback rack next door expands. Every feminized line started as a regular one, each new cross needs a male at some point in its history, and the breadth of cannabis genetics that survives at all survives only because someone kept 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 meant to be a population, not a one plant. This article sets out the argument for that unfashionable pack: what the male contributes, what a grower loses by not growing one, and how to get value with a population instead of a clone.
Not Just Pollen
The easy account of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is the whole of 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 mother.
A male contributes growth habit, hybrid vigour, flowering time, tolerance to mould and pests, resin production and the aromatic chemistry exactly as the female does; it just expresses some of those qualities less because it never produce a finished flower. Breeders who breed with regular seed invest at least as much time choosing males as females, and this is the work that a feminized line inherits and can never replicate. Reversing a female gives pollen; it does not provide a different line of selected genes.
How Diversity Leaks Away
Much of the feminized catalogue is made from S1 seeds: a single famous clone, treated and pollinated with itself. Each generation of that process cuts in half the surviving genetic diversity, and after a couple of rounds what is left is close to one plant expressed across marginally different forms.
That is fine for a consumer who needs that one plant. It is a loss for everyone downstream. Recessive faults surface: intersex tendencies, weak stems, susceptibility to a particular mould. Traits that were present in the parent line but absent in the selected clone vanish out of the gene pool entirely. A generation of this produces a market full with variations of a dozen clones, and a breeder trying to make something new finds there is nothing left to cross. Regular seed from an outcrossed line is the store that replenishes the pool, and it can only persist as long as people keep growing it.
How to Judge a Male
Articles on selecting females are easy to find; guidance on choosing males is rare, because most people do not keep one past the first week of flower to look. For anyone producing seed, the following are the marks breeders watch for.
- Stability. A male that also shows female flowers under normal stress is rejected outright; the tendency is the one thing worth breeding into a line.
- Resin on the stem. Rub a stem or a pollen sac and smell it. A male with trichomes on its flower parts and a clear aroma suggests it holds the terpene traits worth passing on.
- Timing. A male that shows sex early and flowers in step with the females is far more useful than an early one that releases pollen before any female is ready.
- Restraint. Males that release huge amounts of pollen early are frequently also the least desirable in other respects; many breeders favour moderate shedders.
Thinking in Numbers
The error new regular-seed buyers make is treating 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 point of growing it is to observe the spread and choose from it.
Roughly half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to cull or assess for breeding. Within the females, look for real variation: height, flowering time, aroma, density, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who takes cuttings from the strongest female and the best male has something a feminized pack cannot supply: a pair of selected parents that are theirs.
From One Pack to the Next
Owning selected parents is only worth something if making the next batch, and here the options open up. The main approaches cover most of what home breeders do.
- Backcross. Cross a selected offspring again to one of its parents to lock in a specific trait. It narrows the genetics quickly and is used when a single plant shows something worth concentrating and the other brought mainly vigour.
- Open pollination. Let every male pollinate every female. It preserves the whole diversity of the line, produces a generous volume of seed, and involves no choosing at all. This is how landrace lines are kept alive, and it is the correct method when the goal is preservation not improvement.
- Selected cross. One picked male on one or a few picked females, everything else removed. The offspring inherit the traits of the two selected plants and express narrower variation than the original pack. Repeated over several rounds with consistent choices, this is how a stable line is built.
Each of these need nothing more than a separate space for the male, a soft brush or a paper bag, and patience. None of them needs the chemical reversal that feminized production requires.
Landraces and Heirloom Lines
Some lines have never feminized and probably never will be: landraces gathered from regions where cannabis grew over centuries, and old crosses from the first decades of modern breeding. They are sold as regular seed since the breeders keeping them treat diversity 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 different from running a modern hybrid. There will be wide variation, extended flowering times in tropical lines, tall plants, and qualities that make sense in a mountain valley but not in a tent. Expect too flavours and effects that do not appear in the commercial market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, with each line marked with its region of collection and the generation it has been reproduced from the first collection.
The Honest Exclusions
None of the above turns regular seed into the best option for everyone, and pretending that it is would the product no favours.
A grower with space for three plants who needs each one of them to finish is far better off with feminized seed. The same is anyone unable to inspect the plants each day during the start of flower, because a late male in a confined space ruins everything within days. A person growing a single autoflower on a balcony has no use from a population they cannot choose from. And a buyer who is after a known clone-only cut repeated exactly is better off looking for a feminized S1, not a two-parent cross. Regular seed is for the grower who wants to choose, to hold onto and at some point to produce something new; for everyone else the back shelf is safely left where it is.
Practicalities
Breeder Regular Seeds sends each order in unmarked packaging with the original packs intact inside and nothing on the exterior to reveal the contents. Orders to the United States are not taken, as seed importation is not permitted there. Seed law differs widely by country: in many places owning seeds is legal as genetic preservation while germinating them is not, and in others both are allowed under licence or neither is. Knowing the position where you live is the buyer’s responsibility, and nothing of this article should be read as legal advice.
