Any cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide covers 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 properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of nutrients to power the first days of growth.
Genetically, each seed is a one-off combination of its two parents, and that is why two seeds from the same pack can grow noticeably different. Breeders narrow that variation by stabilising 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 trade that certainty for vigour, a strong taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
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 about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they mean identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that make 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 seeds are bred to yield 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.
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.
Males: Asset or Liability?
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 thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population frequently prefer the wider genetic spread of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they get long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: veg for two weeks or two months, train the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and most of it is more informative than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
- 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.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing copy.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are dead.
- Surface. A faint waxy sheen is typical. Cracks, dimples or visible mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is common but crude: fresh seeds often float until the shell absorbs water.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either condition on its own; open the container as rarely as possible.
Getting a Taproot
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can drown.
- Move them to a moist paper towel within a closed container, or directly into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stops the seedling for good.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a middleman of uncertain stock appears in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
- Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be stated up front.
- Breeder transparency. A trustworthy seller names 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.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The claim requires 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 differs widely by country. In many European countries seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries possession of seeds alone is banned.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
Why did a seed fail to germinate?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are rarer than grower error.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Are autoflowering seeds weaker?
Current autos are far closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency from reputable breeders is comparable.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently much longer. Kept in a warm drawer, viability drops noticeably within a year.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
