Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, marked cheaper than the feminized packs next to it, and picked up by a shrinking group of people who understand exactly what they are looking for. It is easy to see 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 female-only line started as a regular one, each new cross requires a male at some point in its pedigree, and the diversity of cannabis genetics that exists at all survives only because someone held onto regular seed. Specialists such as https://breederregularseeds.com carry lines going back to the 1980s, sold in packs of 10 seeds because a pack is intended to be a population, not a single plant. This article makes the argument for that unfashionable pack: what the male is for, what a buyer loses by not seeing one, and how to work with a pack instead of a copy.
Not Just Pollen
The lazy description of a male cannabis plant is “a pollen source”, 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 attention as the mother.
A male passes on structure, hybrid vigour, flowering time, resistance to mould and pests, trichome density and the terpene profile exactly as the female does; it just expresses some of those traits less because it does not grows a smokable flower. Breeders who work with regular seed spend at least as much time choosing males as females, which is the effort that a feminized cross inherits and can never replicate. Feminizing a female gives pollen; it cannot give a second set of selected traits.
What Happens When Lines Are Only Selfed
A great deal of the feminized market is built from S1 seeds: a one popular clone, reversed and crossed with itself. Each generation of that selfing halves the remaining genetic variation, and after a couple of generations what remains is essentially one plant expressed in marginally different forms.
This is fine for a grower who wants that one plant. It is a loss for everyone downstream. Hidden faults surface: intersex tendencies, brittle stems, sensitivity to one particular mould. Qualities that were present in the original line but not in the selected clone vanish out of the population altogether. A decade of this leaves a market crowded with variations of a dozen clones, and a anyone trying to create something new finds there is little left to cross. Regular seed from an outcrossed line is the store that replenishes the market, and that reservoir only persist if somebody keep growing it.
Reading a Male Plant
Articles on choosing females are everywhere; guidance on picking males is scarce, because most people never keep one long enough to judge. For anyone making seed, these are the signs breeders watch for.
- Timing. A male that declares sex early and matures in step with the females is far more workable than an early one that releases pollen before the female is ready.
- Stability. Any male that also shows female flowers under ordinary stress is rejected without exception; that trait is the last thing anyone wants carrying into a line.
- Structure. Short internodes, a thick central stem and branching that resembles the desired female habit are inherited; a lanky, weak-stemmed male hands that down too.
- Resin on the stem. Scratch a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong scent suggests it holds the resin traits worth keeping.
Thinking in Numbers
A error new regular-seed growers make is seeing a pack as 10 attempts 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 observe the spread and choose from it.
About half the plants will be male, so a pack of 10 seeds gives around five females to compare and five males to either cull or judge for breeding. Within the females, look for real differences: stature, flowering time, aroma, density, resistance. That spread is not a failure 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 pair of chosen parents that are theirs.
Three Ways to Cross
Owning chosen parents is only worth something if producing the next batch, and there the options multiply. Three approaches cover most of what small-scale breeders do.
- Selected cross. One chosen male on one or a few chosen females, everything else removed. The offspring carry the traits of the two selected plants and express less variation than the original 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 full diversity of the line, makes a large volume of seed, and involves no selection at all. This is how traditional lines are kept alive, and it is the right method when the goal is preservation not refinement.
- Backcross. Cross a chosen offspring back to one of its parents to fix a particular trait. It narrows the range quickly and is used when a single plant shows something worth keeping and the second contributed mostly vigour.
All three need nothing more than a separate space for the male, a paintbrush or a paper bag, and patience. Not one of them calls for the chemical treatment that feminized production requires.
Landraces and Heirloom Lines
Some lines were never been feminized and probably never will be: landraces gathered from regions where cannabis was grown over centuries, and heirloom hybrids from the early decades of modern breeding. They are available as regular seed because the breeders keeping them treat diversity as the entire value, and selfing a single plant would destroy precisely what makes the line worth keeping.
Growing a landrace from regular seed is a different experience from running a commercial hybrid. There will be wide variation, long flowering times in tropical lines, lanky plants, and qualities that make sense in a mountain valley but not under a tent. Expect too aromas and effects that no longer exist in the commercial market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line marked with its region of origin and the generation it has been reproduced since the first collection.
The Honest Exclusions
None of the above turns regular seed the right choice for everyone, and pretending that it is does the product no favours.
A grower with space for three plants who wants each one of them to flower is better off with feminized seed. So is a grower who cannot afford to check the plants every day during the onset of flower, because a missed male in a confined space seeds the whole crop within days. A person growing a single autoflower on a balcony has no use from a pack they cannot choose from. And a buyer who is after a known clone-only cut repeated as closely as possible is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to keep and at some point to produce something of their own; for anyone else the back shelf is best left alone.
Ordering and the Law
Breeder Regular Seeds dispatches 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 restricted there. Seed law varies widely by country: in many places owning seeds is legal as genetic preservation while germinating them is not, and in others both are permitted 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.
