Browse through most seed shops today and the regular section is a shelf at the back: smaller every year, priced lower than the feminized packs next to it, and bought by a shrinking group of people who know exactly what they are looking for. It is tempting to see that as the end of a technology. It is nearer to the truth to read it as a library losing shelves while the bookshop next door grows. Every feminized line began as a regular one, each new cross needs a male at some point in its pedigree, and the breadth of cannabis genetics that exists at all exists because someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com stock lines that trace to the 1980s, offered in packs of 10 seeds since 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 gives up by never seeing one, and how to get value with a pack 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 for a flower grower that is the whole of it. To a breeder it is half the genome of every seed which follows, and that half is selected with the same care as the mother.
A male passes on growth habit, vigour, maturation speed, tolerance to mould and pests, resin production and the aromatic chemistry just as the female does; it just expresses several of those qualities less because it never produce a smokable flower. Those who work with regular seed spend at least as much time selecting males as females, which is the work that a feminized line inherits and can never repeat. Feminizing a female gives pollen; it does not give a different set of selected traits.
The Narrowing
Much of the feminized market is made from S1 seeds: a one popular clone, treated and pollinated with itself. Every generation of that selfing cuts in half the surviving genetic diversity, and after two generations what is left is close to one plant repeated in marginally different forms.
This is acceptable for a grower who needs that one plant. It is a problem for everyone downstream. Hidden weaknesses emerge: hermaphrodite tendencies, brittle stems, sensitivity to a particular mould. Traits that were present in the parent line but not in the selected clone disappear out of the gene pool entirely. A decade of such breeding leaves a market crowded with versions of a dozen plants, and a anyone wanting to make something different finds there is little remaining to work with. Regular seed from a true outcrossed line is the store that replenishes the market, and that reservoir can only persist if people keep growing it.
How to Judge a Male
Articles on selecting females are easy to find; guidance on picking males is scarce, 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 resembles the desired female shape are passed on; a stretched, weak-stemmed male passes that on too.
- Stability. A male that at the same time shows female pistils under normal conditions is discarded without exception; that tendency is the one thing worth carrying forward.
- Timing. A male that declares sex early and matures in step with the females is more useful than an early one that releases pollen before the female is receptive.
- Restraint. Plants that dump huge quantities of pollen all at once are often also the least desirable in other respects; many breeders prefer moderate producers.
A Pack Is a Population
The mistake first-time regular-seed buyers fall into is seeing a pack as 10 attempts at the one plant. It is the opposite. A pack from a real 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 gives around five females to evaluate and five males to either discard or assess for breeding. Within 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 for. The grower who keeps the strongest female and the best male now owns something a feminized pack cannot supply: a pair of selected parents which are theirs.
Three Ways to Cross
Holding chosen parents is only worth something if making the next batch, and there the choices open up. Three approaches cover most of what small-scale breeders do.
- Selected cross. One picked male to one or a few chosen females, everything else removed. The offspring carry the qualities of the two specific plants and show less spread than the original pack. Repeated over several rounds with consistent choices, this is how a new line is built.
- Open pollination. Allow every male reach each female. It keeps the full range of the line, produces a large quantity of seed, and involves no choosing at all. This is how traditional lines are maintained going, and it is the correct method when the aim is preservation rather than refinement.
- Backcross. Take a chosen offspring again to one of its original parents to fix a particular quality. It narrows the range quickly and is useful when one plant shows something worth keeping and the other contributed mostly vigour.
Each of these require only a isolated space for the male, a paintbrush or a small bag, and a few weeks. None of them calls for the chemical reversal that feminized seed-making does.
Landraces and Heirloom Lines
Some lines were never feminized and likely never will be: landraces collected from places where cannabis was grown over centuries, and heirloom crosses from the early decades of modern breeding. They are sold as regular seed because the breeders maintaining them regard diversity as the entire value, and selfing a single plant would destroy precisely what makes the line worth the trouble of preserving.
Growing a landrace from regular seed is different from growing a modern hybrid. Expect wide variation, long flowering times in tropical lines, lanky plants, and qualities that make sense in a field but not in a tent. There will be also flavours and chemistry that do not exist in the commercial market anywhere. Breeder Regular Seeds holds a separate landrace and heirloom section, and each line labelled with its origin of origin and the generation it has been grown out from the first collection.
When the Library Is the Wrong Shop
None of the above makes regular seed into the right option for everyone, and claiming otherwise does the category no favours.
A grower with room for a handful of plants who needs each one of them to finish is better off with feminized seed. The same is a grower who cannot afford to check the plants every day during the start of flower, because a late male in a confined space seeds everything within days. Someone growing a single autoflower on a balcony gets no use from a population they cannot choose from. And a buyer who wants a known famous cut reproduced exactly is better off looking for a feminized S1, not a regular cross. Regular seed is for the grower who intends to select, to keep and eventually to make something of their own; for anyone else the back shelf is best left where it is.
Practicalities
Breeder Regular Seeds sends every order in plain packaging with the breeder’s packs sealed inside and nothing on the outside to indicate 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 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 job, and nothing of this article is legal advice.
