What Disappears When Every Seed Is Female
Browse 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 picked up by a dwindling number of people who understand exactly what they are looking for. It is tempting to see that as obsolescence. It is nearer to the truth to see it as a library losing shelves while the paperback rack next door grows. Every female-only line started as a regular one, each new cross needs a male at some point in its history, and the diversity of cannabis genetics that survives at all survives only because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines that trace to the 1980s, sold in packs of 10 seeds because a pack is meant to be a population, not a single plant. This article sets out the case for that half-male pack: what the male contributes, what a grower loses by not growing one, and how to get value with a population rather than a clone.
What a Male Plant Is Actually For
The lazy account 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 which follows, and half is selected with the same attention as the mother.
A male passes on growth habit, vigour, maturation speed, resistance to mould and pests, resin production and the terpene profile just as the female does; it simply expresses some of those traits less visibly since it does not grows a smokable flower. Breeders who work with regular seed spend at least as much time selecting males as females, which is the effort that a feminized cross inherits and cannot replicate. Feminizing a female yields pollen; it does not provide a different set of selected genes.
What Happens When Lines Are Only Selfed
Much of the feminized catalogue is made from S1 seeds: a single popular clone, treated and pollinated with itself. Each generation of that selfing halves the surviving genetic variation, and after a couple of generations what is left is close to one plant expressed across slightly different forms.
This is fine for a consumer who wants that one plant. It is a problem for everyone who comes after. Recessive faults surface: intersex tendencies, brittle stems, susceptibility to one particular mould. Traits that existed in the original line but absent in the selected clone vanish from the population entirely. A generation of this leaves a market crowded with versions of the same few clones, and a anyone trying to make something new finds there is nothing remaining to cross. Regular seed from a true outcrossed line is the reservoir that replenishes the pool, and that reservoir can only exists as long as people grows it.
How to Judge a Male
Articles on choosing females are easy to find; advice on picking males is rare, since most people never keep one past the first week of flower to look. For a grower making seed, the following are the marks breeders look for.
- Restraint. Plants that dump huge amounts of pollen all at once are frequently the less desirable genetically; many breeders favour steady producers.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its flower parts and a strong scent suggests it holds the resin genes that are worth keeping.
- Timing. A male that declares sex early and matures at the same pace as the females is more useful than an early one that sheds pollen before any female is receptive.
- Stability. Any male that also forms female pistils under normal conditions is rejected outright; that tendency is the one thing worth carrying into a line.
- Structure. Short internodes, a strong main stem and branching that resembles the intended female shape are passed on; a stretched, weak-stemmed male hands that on too.
Thinking in Numbers
A error first-time regular-seed growers fall into is treating a pack as 10 attempts at the one plant. It is the opposite. A pack from a genuine outcrossed line is a slice of a population, and the point of growing it is to observe the spread and select 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 discard or assess for breeding. Among the females, look for noticeable differences: stature, flowering time, aroma, density, resistance. This variation is not a flaw in the seed; it is what the seed is selling. The grower who keeps the best female and male now owns something a feminized pack can never offer: a line of chosen parents which are their own.
Three Ways to Cross
Owning selected parents is only worth something if making the next batch, and here the options open up. The main approaches account for most of what home breeders attempt.
- Backcross. Take a selected offspring again to one of its parents to lock in a particular trait. It tightens the range fast and is used when one parent shows something worth concentrating and the second brought mainly vigour.
- Selected cross. One chosen male to one or a few chosen females, everything else removed. The seeds carry the qualities of two selected plants and show narrower variation than the parent pack. Repeated over generations with consistent choices, this is how a new line is made.
- Open pollination. Let each male reach every female. It keeps the whole diversity of the line, produces a generous volume of seed, and does no choosing at all. This is how traditional lines are kept alive, and it is the correct approach when the aim is preservation rather than refinement.
All three need only a separate space for the male, a soft brush or a paper bag, and a few weeks. None of them calls for the chemical treatment that feminized seed-making does.
Landraces and Heirloom Lines
Some lines have never been feminized and likely never will be: landraces gathered from regions where cannabis grew over centuries, and heirloom hybrids from the first decades of modern breeding. They are sold as regular seed because the people keeping them treat the population as the entire value, and reversing a single plant would destroy exactly what makes the line worth the trouble of keeping.
Running a landrace from regular seed is a different experience from running a commercial hybrid. There will be 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 too aromas and effects that do not appear in the hybrid market at all. Breeder Regular Seeds keeps a dedicated landrace and heirloom section, with each line labelled with its origin of collection and the number of generations it has been grown out from the first collection.
Who Should Not Buy Regular Seeds
Nothing of the above turns regular seed the right option for everyone, and claiming that it is would the category no favours.
A grower with space for three plants who wants each one of them to finish is better served with feminized seed. So is a grower who cannot afford to inspect the plants each day during the start of flower, since a late male in a small space ruins the whole crop inside days. A person growing a single autoflower on a balcony has no value from a pack they cannot choose from. And a buyer who is after a known clone-only plant repeated exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who wants to choose, to hold onto and at some point to make something new; for anyone else the back shelf is best left alone.
Ordering and the Law
Breeder Regular Seeds sends each order in plain parcels with the original packs sealed inside and nothing 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 many places buying seeds is legal as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Checking the position in your own jurisdiction is the buyer’s responsibility, and nothing of this article should be read as legal advice.
