Browse through most seed shops today and the regular section is the shelf at the back: shorter every year, marked cheaper than the feminized packs next to it, and bought by a dwindling group of people who understand exactly what they are looking for. It is easy to see that as the end of a technology. It is nearer to the truth to read it as a library shrinking while the paperback rack next door grows. Every feminized line started 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 someone held onto regular seed. Dedicated sellers such as https://breederregularseeds.com carry lines going back to the 1980s, offered in packs of 10 seeds because a pack is meant to be a population, not a one plant. This article makes the case for that half-male pack: what the male is for, what a buyer loses by never seeing one, and how to get value with a pack instead of a clone.
Not Just Pollen
The easy description of a male cannabis plant is “the one that makes pollen”, and to a flower grower that is all it. To a breeder it is half the genome of every seed which follows, and half is chosen with the same care as the mother.
A male contributes structure, hybrid vigour, maturation speed, resistance to mould and pests, resin density and the aromatic chemistry exactly as the female does; it just expresses some of those qualities less visibly since it does not produce a smokable flower. Breeders who breed with regular seed spend at least as much time choosing males as females, which is the effort that a feminized cross borrows and cannot replicate. Reversing a female gives pollen; it cannot provide a second set of selected genes.
What Happens When Lines Are Only Selfed
A great deal of the feminized catalogue is made from S1 seeds: a one popular clone, treated and crossed with itself. Every round of that process cuts in half the remaining genetic variation, and after a couple of generations what is left is close to one plant expressed in slightly different forms.
This is fine for a consumer who wants that single plant. It is a loss for everyone who comes after. Hidden weaknesses surface: intersex tendencies, weak stems, sensitivity to a particular mould. Traits that were present in the original line but not in the chosen clone vanish from the gene pool altogether. A decade of this leaves a market full with variations of a dozen plants, and a anyone trying to make something different finds there is little remaining to cross. Regular seed from an outcrossed line is the reservoir that refills the market, and that reservoir only persist if people keep growing it.
Reading a Male Plant
Guides on selecting females are easy to find; guidance on picking males is rare, because most people never 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 shows female pistils under ordinary conditions is rejected outright; that trait is the one thing anyone wants breeding forward.
- Structure. Short internodes, a strong main stem and a frame that resembles the desired female habit are passed on; a stretched, weak-stemmed male hands that down too.
- Timing. A male that shows sex first and flowers in step with the females is more useful than an early one that releases pollen before any female is receptive.
- Resin on the stem. Rub a stem or a flower cluster and smell it. A male with trichomes on its sepals and a strong scent indicates it holds the resin traits that are worth keeping.
- Restraint. Males that release huge amounts of pollen early are frequently also the less desirable genetically; breeders favour steady shedders.
What 10 Seeds Actually Give You
The mistake first-time regular-seed buyers make is seeing a pack as 10 chances at the same plant. It is nothing of the kind. A pack from a real outcrossed line is a sample of a population, and the point of growing it is to observe the range and choose from it.
About half the plants will be male, so a pack of 10 seeds yields around five females to evaluate and five males to either cull or judge for breeding. Within the females, look for noticeable differences: stature, finishing time, smell, density, resistance. That variation is not a failure in the seed; it is what the seed is for. The grower who keeps the strongest female and male now owns something a feminized pack cannot supply: a pair of selected parents which are theirs.
Three Ways to Cross
Holding chosen parents means producing the next generation, and there the options multiply. Three methods account for most of what home breeders do.
- Open pollination. Allow each male reach every female. It preserves the whole diversity of the line, makes a large quantity of seed, and does no choosing at all. This is how landrace lines are kept alive, and it is the right method when the aim is preservation not refinement.
- Backcross. Take a chosen offspring back to one of its parents to fix a particular trait. It narrows the range quickly and is useful when a single parent shows something worth keeping and the other brought mainly vigour.
- Selected cross. One chosen male on one or a few chosen females, every other plant else culled. The offspring carry the traits of two selected plants and express narrower variation than the original pack. Done over several rounds with stable choices, this is how a new line is built.
Each of these need only a separate space for the male, a paintbrush or a paper bag, and patience. Not one of them needs the chemical reversal that feminized seed-making does.
Landraces and Heirloom Lines
Some lines have never feminized and likely never will be: landraces gathered from regions where cannabis was grown for centuries, and old hybrids from the early decades of modern breeding. They are available as regular seed because the people keeping them regard diversity as the entire point, and selfing a single clone would destroy exactly what makes the line worth the trouble of keeping.
Growing a landrace from regular seed is a different experience from growing a commercial hybrid. Expect wide variation, long flowering periods in tropical lines, tall plants, and traits that make sense in a mountain valley but not in a small room. Expect too flavours and chemistry that do not appear in the hybrid market anywhere. Breeder Regular Seeds keeps a separate landrace and heirloom section, and each line labelled with its origin of origin and the number of generations it has been reproduced from the original collection.
When the Library Is the Wrong Shop
Nothing of the above turns regular seed the best option for everyone, and pretending that it is does the product no service.
A grower with room for three plants who wants each one of them to finish is far better off with feminized seed. The same is a grower unable to check the plants every day during the start of flower, because a missed male in a confined space seeds the whole crop within days. Someone running a single autoflower on a balcony gets no use from a population they cannot choose from. And a buyer who wants a specific clone-only cut repeated exactly 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 at some point to produce something of their own; for anyone else the back shelf is best ignored alone.
Ordering and the Law
Breeder Regular Seeds dispatches each order in plain parcels with the original packs sealed inside and no on the outside to indicate the contents. Orders to the United States are not taken, because seed importation is not permitted there. Seed law varies sharply by country: in a good number of places owning seeds is lawful as collectables while germinating them is not, and in others both are allowed under local rules or both is. Knowing the rules where you live is the buyer’s responsibility, and nothing of this article is legal advice.
