Browse through most seed shops today and the regular section is a shelf at the back: shorter every year, priced lower than the feminized packs next to it, and picked up by a dwindling group of people who understand exactly what they are looking for. It is tempting to read that as the end of a technology. It is nearer to the truth to see it as a library losing shelves while the paperback rack next door grows. Every feminized line began as a regular one, each new cross requires a male at some point in its history, and the breadth of cannabis genetics that survives at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry lines that trace to the 1980s, offered in packs of 10 seeds since a pack is intended to be a population, not a one plant. This article sets out the argument for that half-male pack: what the male is for, what a buyer gives up by never growing one, and how to get value with a population rather than a copy.
The Other Half of the Genome
The easy description of a male cannabis plant is “the one that makes pollen”, and for a flower grower that is all it. For a breeder it is half the genome of every seed which follows, and half is chosen with the same attention as the female.
A male contributes growth habit, hybrid vigour, maturation time, tolerance to mould and pests, trichome production and the terpene chemistry just as the female does; it just expresses several of those qualities less visibly since it does not grows a finished flower. Those who breed with regular seed invest as much time selecting males as females, and this is the effort that a feminized cross borrows and can never replicate. Reversing a female gives pollen; it does not give a second set of selected traits.
What Happens When Lines Are Only Selfed
A great deal of the feminized catalogue is made from S1 seeds: a single famous clone, treated and pollinated with itself. Each round of that process halves the surviving genetic variation, and after two generations what remains is close to one plant expressed across slightly different ways.
This is fine for a grower who needs that one plant. It is a problem for everyone downstream. Recessive faults surface: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Traits that were present in the parent line but absent in the chosen clone disappear out of the population entirely. A generation of such breeding produces a market crowded with versions of the same few plants, and a breeder trying to make something different finds there is nothing remaining to work with. Regular seed from a true outcrossed line is the reservoir that replenishes the market, and that reservoir only persist as long as somebody keep growing it.
Reading a Male Plant
Articles on selecting females are everywhere; guidance on picking males is rare, since most people do not keep one long enough to look. For a grower making seed, the following are the signs breeders watch for.
- Structure. Short internodes, a thick central stem and a frame that matches the intended female shape are passed on; a stretched, weak-stemmed male hands that on too.
- Stability. Any male that also shows female flowers under normal stress is rejected outright; the tendency is the last thing worth carrying forward.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with resin on its sepals and a strong aroma indicates it holds the resin traits worth keeping.
- Timing. A male that shows sex early and flowers in step with the females is far more workable than an early one that sheds pollen before the female is ready.
- Restraint. Plants that release enormous amounts of pollen early are frequently also the least selected genetically; breeders favour steady shedders.
Thinking in Numbers
The error first-time regular-seed growers fall into is treating a pack as 10 chances at the same plant. It is the opposite. A pack from a genuine outcrossed line is a sample of a population, and the value of running it is to see 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. Within the females, expect noticeable differences: stature, flowering time, smell, density, tolerance. That spread is not a flaw in the seed; it is what the seed is selling. The grower who keeps the strongest female and the best male has something a feminized pack can never offer: a line of selected parents that are their own.
Making Your Own Seed
Owning chosen parents is only worth something if making the next batch, and here the options open up. The main methods cover most of what small-scale breeders do.
- Selected cross. One picked male on one or several chosen females, every other plant else removed. The offspring carry the qualities of two specific plants and express narrower variation than the parent pack. Repeated over several rounds with stable choices, this is how a stable line is built.
- Open pollination. Let every male reach every female. It preserves the whole diversity of the line, produces a large quantity of seed, and involves no choosing at all. This is how traditional lines are kept going, and it is the right approach when the aim is preservation not refinement.
- Backcross. Cross a chosen seedling again to one of its parents to lock in a specific quality. It tightens the genetics fast and is useful when one plant has something worth concentrating and the other brought mostly vigour.
Each of these require only a isolated space for the male, a soft brush or a paper bag, and patience. None of them calls for the chemical treatment that feminized production does.
Keeping Old Lines Alive
Some lines were never feminized and probably never will be: landraces collected from regions where cannabis was grown for centuries, and old crosses from the early decades of modern breeding. They are sold as regular seed since the breeders keeping them treat the population as the whole value, and reversing a single clone would destroy precisely what makes the line worth keeping.
Growing a landrace from regular seed is a different experience from growing a commercial hybrid. There will be wide variation, long flowering times in equatorial lines, lanky plants, and traits that make sense in a field but not under a small room. Expect too flavours and chemistry that no longer exist in the hybrid market at all. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its region of origin and the number of generations it has been reproduced since the original collection.
Who Should Not Buy Regular Seeds
None of the above makes regular seed the best option for everyone, and pretending that it is does the category no favours.
A grower with space for three plants who wants every one of them to flower is far better served with feminized seed. The same is anyone who cannot afford to check the plants each day around the start of flower, since a missed male in a small space seeds everything inside days. Someone running a single autoflower on a balcony has no value from a pack they cannot choose from. And anyone who is after a specific clone-only cut reproduced as closely as possible is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to hold onto and at some point to produce something of their own; for anyone else the back shelf is best ignored where it is.
Ordering and the Law
Breeder Regular Seeds dispatches every order in unmarked packaging with the breeder’s packs sealed inside and nothing on the outside to reveal the contents. Orders to the United States are not accepted, because seed importation is restricted there. Seed law varies widely by country: in a good number of places owning seeds is legal as genetic preservation while germinating them is not, and in others the two are permitted under local rules or both is. Knowing the position in your own jurisdiction is the buyer’s responsibility, and no part of this article is legal advice.
