Any cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. This guide explains the main seed types, how to read a strain description, what separates a good seed from a poor one, and how to store and start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically brown, grey or tiger-striped, solid to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a reserve of nutrients to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, which is why two seeds from the same pack can grow noticeably unalike. Breeders reduce that variation by working a line over many generations, but some spread is normal in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, but they mean identifying and removing males before they pollinate the females.
- Feminized seeds are bred to produce female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of imperfect conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description normally says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is space, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue completely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a mother plant from a large population often prefer the wider genetic spread of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants remain in vegetative growth as long as they get long days and move to flowering when the light drops to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants remain small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing text.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few signs are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Surface. A faint waxy sheen is normal. Cracks, dimples or visible mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell absorbs water.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and change.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as seldom as possible.
The First Five Days
Every grower has a favourite method, but the requirements are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a serious seed bank and a reseller of unknown stock appears in germination rates, rather than on the website.
- Breeder transparency. A good seller lists the breeder for every strain. Bud Weed Seeds carries lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder named on each product page.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be spelled out in plain language.
- Pack options. Multiple pack sizes let you to test a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in plain packaging with no mention to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds replaces it. The request needs the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays an offence. In other places both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Are autoflowering seeds less potent?
Modern autos are far closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency in good lines is comparable.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently much longer. Left in a warm drawer, viability falls sharply within a year.
