Walk through most seed shops today and the regular section is a shelf at the back: smaller every year, marked cheaper than the feminized packs next to it, and bought by a shrinking number of people who know exactly what they are after. 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 began as a regular one, each new cross requires a male at some point in its pedigree, and the breadth of cannabis genetics that survives at all exists because somebody held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back 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 case for that unfashionable pack: what the male contributes, what a grower loses by never growing one, and how to work with a population rather than a clone.

Not Just Pollen

The lazy account of a male cannabis plant is « the one that makes pollen », and to 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 care as the female.

A male contributes structure, hybrid vigour, maturation speed, resistance to mould and pests, trichome production and the terpene chemistry exactly as the female does; it simply shows several of those traits less because it does not grows a finished flower. Those who work with regular seed invest as much time choosing males as females, and this is the work that a feminized line borrows and cannot repeat. Reversing a female gives pollen; it cannot give a different line of selected genes.

How Diversity Leaks Away

Much of the feminized catalogue is built from S1 seeds: a single famous clone, treated and crossed with itself. Every generation of that process cuts in half the remaining genetic variation, and after two rounds what remains is essentially one plant expressed in marginally different forms.

This is fine for a grower who needs that single plant. It is a problem for everyone who comes after. Recessive weaknesses surface: hermaphrodite tendencies, brittle stems, sensitivity to a particular mould. Traits that were present in the parent line but absent in the chosen clone vanish from the gene pool entirely. A generation of this produces a market crowded with versions of a dozen clones, and a breeder wanting to make something new finds there is little left to cross. Regular seed from an outcrossed line is the store that refills the pool, and that reservoir only persist if somebody keep growing it.

Selecting the Plant Nobody Writes About

Articles on choosing females are easy to find; advice on picking males is scarce, since most growers do not keep one past the first week of flower to look. For anyone making seed, the following are the signs breeders look for.

  • Stability. A male that also forms female pistils under normal conditions is discarded without exception; the tendency is the last thing worth breeding forward.
  • Resin on the stem. Scratch a stem or a flower sac and smell it. A male with trichomes on its sepals and a strong aroma indicates it carries the resin genes worth keeping.
  • Timing. A male that shows sex first and matures at the same pace as the females is far more useful than a very early one that releases pollen before any female is ready.
  • Structure. Short internodes, a thick main stem and a frame that resembles the intended female habit are inherited; a lanky, weak-stemmed male passes that on too.

A Pack Is a Population

A error first-time regular-seed buyers 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 growing it is to see the spread and choose from it.

Roughly half the plants will be male, which means a pack of 10 seeds yields something like five females to compare and five males to discard or judge for breeding. Within the females, look for noticeable differences: height, flowering time, smell, density, tolerance. This variation is not a failure 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 cannot supply: a pair of chosen parents which are their own.

From One Pack to the Next

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

  • Selected cross. One chosen male on one or a few picked females, every other plant else culled. The offspring carry the traits of two selected plants and express less variation than the original pack. Repeated over generations with stable selection, this is how a stable line is built.
  • Backcross. Cross a selected seedling back to one of its parents to lock in a specific trait. It narrows the range quickly and is used when a single plant has something worth keeping and the other brought mostly vigour.
  • Open pollination. Allow each male reach each female. It keeps the full range of the line, produces a generous quantity of seed, and does no selection at all. This is how traditional lines are maintained going, and it is the correct method when the aim is preservation not refinement.

All three require nothing more than a separate space for the male, a soft brush or a paper bag, and a few weeks. Not one of them calls for the chemical treatment that feminized seed-making does.

The Seeds That Only Exist as Regulars

A number of lines have never feminized and probably never will be: landraces gathered from places where cannabis was grown for centuries, and heirloom crosses from the early decades of indoor breeding. They are sold as regular seed because the people maintaining them regard diversity as the whole point, and reversing a single plant would erase precisely what makes the line worth the trouble of preserving.

Running a landrace from regular seed is a different experience from growing a modern hybrid. Expect large variation, extended flowering times in tropical lines, lanky plants, and qualities that make sense in a mountain valley but not under a small room. Expect too flavours and chemistry that do not appear in the commercial market at all. Breeder Regular Seeds keeps a separate landrace and heirloom section, with each line marked with its origin of origin and the generation it has been grown out from the original collection.

When the Library Is the Wrong Shop

None of the above makes regular seed the best option for everyone, and pretending otherwise does the product no favours.

A grower with room for a handful of plants who needs every one of them to flower is better off with feminized seed. So is anyone unable to inspect the plants each day during the start of flower, because a late male in a confined space ruins everything within days. Someone growing a single autoflower on a balcony gets no use from a population they cannot select from. And a buyer who wants a specific famous plant 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 choose, to hold onto and eventually to make something new; for everyone 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 taken, because seed import is restricted there. Seed law differs widely by country: in many places buying seeds is legal as genetic preservation while germinating them is not, and in others the two are allowed under local rules or both is. Knowing the position in your own jurisdiction is the buyer’s job, and no part of this article should be read as legal advice.
