Walk through most seed shops today and the regular section is the shelf at the back: smaller every year, marked cheaper than the feminized packs beside it, and bought by a dwindling group of people who know exactly what they are looking for. It is tempting to read 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 grows. Every female-only line began as a regular one, every new cross requires a male somewhere in its pedigree, and the breadth of cannabis genetics that survives at all survives only because somebody 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 meant 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 grower gives up by never seeing one, and how to work with a pack rather than a clone.
What a Male Plant Is Actually For
The easy description of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. For 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 passes on growth habit, hybrid vigour, flowering time, tolerance to mould and pests, trichome density and the terpene profile just as the female does; it just shows several of those traits less because it never grows a smokable flower. Breeders who breed with regular seed invest at least as much time selecting males as females, and this is the effort that a feminized cross borrows and can never repeat. Reversing a female gives pollen; it does not provide a second line of selected traits.
How Diversity Leaks Away
Much of the feminized catalogue is made from S1 seeds: a one popular clone, reversed and pollinated with itself. Every round of that process cuts in half the remaining genetic variation, and after a couple of generations what remains is close to one plant expressed across marginally different ways.
This is fine for a grower who wants that single plant. It is a loss for everyone downstream. Hidden faults surface: hermaphrodite tendencies, weak stems, sensitivity to a particular mould. Qualities that were present in the parent line but not in the selected clone vanish from the gene pool altogether. A decade of this produces a market crowded with versions of a dozen plants, and a anyone trying to make something different finds there is little remaining to cross. Regular seed from a true outcrossed line is the store that replenishes the pool, and it can only persist as long as people grows it.
Selecting the Plant Nobody Writes About
Guides on selecting females are easy to find; guidance on choosing males is scarce, since most growers never keep one past the first week of flower to look. For anyone producing seed, the following are the signs breeders watch for.
- Structure. Tight internodes, a thick main stem and branching that matches the intended female habit are passed on; a lanky, weak-stemmed male hands that on too.
- Resin on the stem. Scratch a stem or a pollen cluster and smell it. A male with trichomes on its flower parts and a strong scent suggests it carries the resin traits that are worth keeping.
- Timing. A male that shows sex first and flowers in step with the females is more useful than a very early one that sheds pollen before any female is ready.
- Stability. Any male that also shows female flowers under ordinary stress is discarded outright; the tendency is the last thing worth carrying into a line.
A Pack Is a Population
A mistake first-time regular-seed growers fall into is treating a pack as 10 chances at the one plant. It is nothing of the kind. A pack from a real outcrossed line is a slice of a population, and the point of running it is to observe the spread and select from it.
Roughly half the plants will be male, so a pack of 10 seeds gives around five females to evaluate and five males to discard or judge for breeding. Within the females, look for noticeable differences: height, flowering time, aroma, bud structure, resistance. That 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 cannot supply: a pair of chosen parents which are their own.
Three Ways to Cross
Owning selected parents means making the next batch, and there the options multiply. Three approaches cover most of what small-scale breeders attempt.
- Selected cross. One picked male on one or a few picked females, every other plant else removed. The offspring inherit the traits of the two selected plants and express less variation than the original pack. Repeated over several rounds with consistent choices, this is how a stable line is built.
- Backcross. Take a chosen offspring back to one of its original parents to lock in a particular quality. It tightens the range quickly and is used when a single plant has something worth concentrating and the second brought mostly vigour.
- Open pollination. Allow each male reach each female. It keeps the full range of the line, makes a generous volume of seed, and involves no selection at all. This is how traditional lines are kept alive, and it is the correct method when the aim is preservation not refinement.
All three need nothing more than a isolated space for the male, a soft brush or a small bag, and a few weeks. Not one of them calls for the chemical reversal that feminized production does.
The Seeds That Only Exist as Regulars
A number of lines have never feminized and probably never will be: landraces collected from regions where cannabis was grown over centuries, and old hybrids from the early decades of indoor breeding. They are sold as regular seed since the people maintaining them treat the population as the entire point, and reversing a single clone would destroy exactly what makes the line worth keeping.
Growing a landrace from regular seed is different from growing a modern hybrid. Expect large variation, long flowering times in equatorial lines, tall plants, and traits that made sense in a mountain valley but not under a tent. Expect also aromas and effects that no longer appear in the hybrid market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its origin of collection and the generation it has been grown out from the original collection.
The Honest Exclusions
Nothing of the above makes regular seed into the right choice for everyone, and claiming that it is would the category no favours.
A grower with room for a handful of plants who wants every one of them to flower is far better off with feminized seed. The same is anyone unable to inspect the plants every day around the onset of flower, since a missed male in a confined space ruins everything inside days. A person running a single autoflower on a balcony has no value from a pack they cannot choose from. And a buyer who wants a known clone-only plant repeated exactly is looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to select, to keep and eventually to make something new; for everyone else the back shelf is best ignored alone.
Practicalities
Breeder Regular Seeds sends each order in unmarked parcels with the breeder’s packs sealed inside and nothing on the exterior to indicate the contents. Orders to the United States are not accepted, as seed importation is not permitted there. Seed law varies widely by country: in a good number of places owning seeds is lawful as genetic preservation while germinating them is not, and in others the two are permitted under licence or both is. Checking the rules in your own jurisdiction is the buyer’s responsibility, and nothing of this article is legal advice.
