Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, marked lower than the feminized packs beside it, and picked up by a shrinking number of people who know exactly what they are after. It is easy to read that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the bookshop next door expands. Every female-only line started as a regular one, each new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that survives at all exists only because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article sets out the case for that half-male pack: what the male is for, what a grower gives up by not seeing one, and how to get value with a pack instead of a clone.
Not Just Pollen
The easy account of a male cannabis plant is “a pollen source”, and for a flower grower that is the whole of it. To a breeder it is half the genome of every seed that follows, and half is chosen with the same care as the mother.
A male contributes growth habit, vigour, maturation time, resistance to mould and pests, trichome production and the terpene profile just as the female does; it simply shows several of those traits less since it never produce a smokable flower. Those who breed with regular seed invest at least as much time selecting males as females, which is the work that a feminized line inherits and can never replicate. Reversing a female gives pollen; it does not provide a second line of selected genes.
The Narrowing
A great deal of the feminized catalogue is built from S1 seeds: a one famous clone, treated and crossed with itself. Each round of that process cuts in half the remaining genetic diversity, and after a couple of generations what remains is close to one plant repeated across slightly different ways.
This is acceptable for a consumer who needs that one plant. It is a loss for everyone downstream. Recessive faults emerge: hermaphrodite tendencies, weak stems, susceptibility to a particular mould. Qualities that existed in the parent line but not in the chosen clone vanish out of the gene pool entirely. A decade of such breeding leaves a market crowded with versions of the same few clones, and a breeder trying to make something different finds there is nothing left to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the market, and it can only persist as long as somebody grows it.
Reading a Male Plant
Articles on selecting females are easy to find; guidance on picking males is rare, since most growers never keep one past the first week of flower to judge. For a grower making seed, the following are the marks breeders look for.
- Restraint. Plants that dump huge amounts of pollen early are frequently also the less desirable in other respects; many breeders prefer moderate producers.
- Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its flower parts and a strong scent indicates it carries the resin traits that are worth passing on.
- Timing. A male that declares sex first and matures in step with the females is far more workable than a very early one that sheds pollen before the female is ready.
- Stability. A male that at the same time forms female flowers under normal stress is rejected outright; the tendency is the one thing anyone wants carrying into a line.
- Structure. Short internodes, a strong main stem and a frame that matches the desired female habit are passed on; a lanky, weak-stemmed male passes that on too.
What 10 Seeds Actually Give You
A mistake new regular-seed growers fall into is seeing a pack as 10 attempts 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 observe the spread and choose from it.
About half the plants will be male, which means a pack of 10 seeds yields something like five females to compare and five males to either discard or assess for breeding. Among the females, look for real variation: stature, finishing time, aroma, density, tolerance. This spread is not a flaw in the seed; it is what the seed is for. The grower who keeps the best female and the best male has something a feminized pack can never supply: a line of chosen parents which are theirs.
Three Ways to Cross
Owning chosen parents means making the next generation, and here the options open up. The main approaches account for most of what home breeders attempt.
- Selected cross. One picked male to one or several picked females, every other plant else culled. The seeds inherit the traits of two selected plants and express less spread than the parent pack. Repeated over several rounds with stable selection, this is how a new line is built.
- Open pollination. Let each male reach each female. It keeps the full diversity of the line, produces a large volume of seed, and involves no selection at all. This is how traditional lines are kept going, and it is the correct method when the aim is preservation not refinement.
- Backcross. Cross a selected offspring again to one of its parents to lock in a particular trait. It narrows the genetics fast and is used when one plant shows something worth keeping and the second brought mainly vigour.
Each of these need nothing more than a separate space for the male, a soft brush or a small bag, and patience. None of them needs the chemical reversal that feminized seed-making requires.
Keeping Old Lines Alive
Some lines have never feminized and likely never will be: landraces collected from regions where cannabis grew over centuries, and old hybrids from the early decades of modern breeding. They are sold as regular seed since the breeders maintaining them regard the population as the entire value, and selfing a single clone would erase precisely what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is different from running a commercial hybrid. Expect large variation, long flowering times in equatorial lines, lanky plants, and traits that make sense in a field but not under a small room. There will be too flavours and chemistry that do not appear in the commercial market anywhere. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its origin of origin and the number of generations it has been grown out from the original collection.
The Honest Exclusions
Nothing of the above turns regular seed into the best choice for everyone, and claiming otherwise would the product no favours.
A grower with space for a handful of plants who wants every one of them to finish is far better off with feminized seed. So is anyone unable to check the plants every day around the start of flower, because a late male in a small space ruins everything within days. Someone running a single autoflower on a balcony gets no use from a population they cannot choose from. And a buyer who wants a specific clone-only plant repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to choose, to hold onto and at some point to make something new; for everyone else the regular shelf is safely left alone.
Ordering and the Law
Breeder Regular Seeds sends every order in unmarked parcels with the breeder’s packs intact inside and no on the outside to indicate the contents. Orders to the United States are not taken, because seed importation is not permitted there. Seed law differs widely by country: in a good number of places owning seeds is legal as collectables while germinating them is not, and in others the two are permitted under licence or neither is. Knowing the position in your own jurisdiction is the buyer’s job, and nothing of this article should be read as legal advice.
