Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, priced cheaper than the feminized packs beside it, and picked up by a shrinking group of people who understand exactly what they are looking for. It is easy to read that as obsolescence. It is nearer to the truth to read it as a library losing shelves while the bookshop next door expands. Every feminized line began as a regular one, every new cross needs a male at some point in its history, and the breadth of cannabis genetics that exists at all survives because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines going back to the 1980s, offered in packs of 10 seeds because 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 contributes, what a grower loses by never growing one, and how to work with a pack rather than a copy.

What a Male Plant Is Actually For

The easy account 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 half is selected with the same attention as the female.

A male contributes structure, hybrid vigour, maturation time, resistance to mould and pests, trichome production and the terpene chemistry exactly as the female does; it just expresses several of those qualities less since it does not produce a finished flower. Those who breed with regular seed invest as much time choosing males as females, which is the effort that a feminized cross inherits and cannot repeat. Reversing a female gives pollen; it does not provide a second set of selected genes.

What Happens When Lines Are Only Selfed

A great deal of the feminized market is made from S1 seeds: a single popular clone, reversed and pollinated with itself. Each generation of that selfing halves the surviving genetic diversity, and after a couple of rounds what is left is essentially one plant repeated in slightly different ways.

This is fine for a consumer who wants that one plant. It is a problem for everyone downstream. Recessive faults surface: intersex tendencies, weak stems, sensitivity to a particular mould. Qualities that were present in the original line but not in the selected clone disappear out of the population entirely. A decade of this produces a market full with versions of a dozen plants, and a anyone wanting to make something different discovers there is little left to cross. Regular seed from a true outcrossed line is the reservoir that refills the pool, and it only exists as long as somebody grows it.

Selecting the Plant Nobody Writes About

Guides on choosing females are easy to find; advice on choosing males is rare, since most growers do not keep one past the first week of flower to judge. For anyone making seed, these are the signs breeders watch for.

• Structure. Short internodes, a strong central stem and a frame that matches the intended female habit are inherited; a stretched, weak-stemmed male hands that on too.
• Stability. Any male that also forms female pistils under normal conditions is discarded without exception; the tendency is the last thing worth carrying into a line.
• Timing. A male that declares sex early and flowers at the same pace as the females is far more useful than an early one that sheds pollen before the female is receptive.
• Resin on the stem. Rub a stem or a flower sac and smell it. A male with resin on its flower parts and a strong aroma suggests it holds the resin genes worth keeping.
• Restraint. Males that dump huge quantities of pollen all at once are frequently the least selected in other respects; breeders favour steady shedders.

A Pack Is a Population

A error new regular-seed growers make is seeing 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 growing it is to observe the range and choose from it.

Roughly half the plants will be male, so a pack of 10 seeds gives something like five females to compare and five males to either discard or assess for breeding. Among the females, look for real differences: height, flowering time, aroma, bud structure, resistance. That variation is not a failure in the seed; it is what the seed is for. The grower who takes cuttings from the strongest female and male has something a feminized pack cannot supply: a line of chosen parents which are theirs.

From One Pack to the Next

Owning selected parents is only worth something if producing the next generation, and here the choices multiply. Three approaches cover most of what home breeders attempt.

• Backcross. Cross a chosen offspring back to one of its parents to fix a specific trait. It tightens the range quickly and is useful when one parent shows something worth keeping and the other brought mostly vigour.
• Open pollination. Allow every male pollinate each female. It preserves the whole range of the line, produces a large quantity of seed, and does no selection at all. This is how traditional lines are maintained alive, and it is the correct approach when the goal is preservation not refinement.
• Selected cross. One picked male to one or several picked females, every other plant else removed. The offspring inherit the traits of the two specific plants and show narrower variation than the original pack. Done over generations with stable selection, this is how a new line is made.

All three need only a separate space for the male, a paintbrush or a small bag, and patience. None of them needs the chemical treatment that feminized production requires.

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 for centuries, and old crosses from the first decades of modern breeding. They are available as regular seed because the breeders maintaining them treat the population as the entire value, and reversing a single clone would destroy precisely what makes the line worth keeping.

Growing a landrace from regular seed is different from running a modern hybrid. Expect large variation, long flowering periods in equatorial lines, tall plants, and qualities that make sense in a mountain valley but not under a tent. There will be also flavours and chemistry that no longer appear in the commercial market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line labelled with its region of origin and the generation it has been reproduced from the first collection.

When the Library Is the Wrong Shop

Nothing of the above makes regular seed the right choice for everyone, and pretending that it is does the product no service.

A grower with space for a handful of plants who wants each one of them to finish is better served with feminized seed. So is anyone who cannot afford to inspect the plants every day during the onset of flower, because a missed male in a confined space ruins everything within days. Someone growing a single autoflower on a balcony has no value from a pack they cannot choose from. And anyone who wants a specific clone-only cut reproduced as closely as possible is 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 make something new; for everyone else the regular shelf is safely ignored where it is.

Ordering and the Law

Breeder Regular Seeds dispatches every order in unmarked parcels with the original packs sealed inside and nothing on the exterior to reveal the contents. Orders to the United States are not accepted, as seed import is restricted there. Seed law differs sharply by country: in many places owning seeds is lawful as collectables while germinating them is not, and in others the two are allowed under local rules or neither is. Knowing the position where you live is the buyer’s responsibility, and no part of this article should be read as legal advice.
