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 saves months of lost effort later. The market has grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. 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 germinate them properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically brown, grey or tiger-striped, firm to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of energy 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 turn out 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 exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
Regular, Feminized, Autoflowering: The Big Three
Nearly 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 produce male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they require identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, faster and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to yield female plants very nearly 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 mutually exclusive: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is space, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic variation 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 difficult to defend.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants remain small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a given footprint usually choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
- 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.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages point 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 temperament far better than any marketing text.
A Quick Viability Check
Appearance is a loose guide to viability, not a verdict, but a few indicators are worth knowing.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
- Surface. A faint waxy sheen is typical. Splits, dents or visible mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Float test. Dropping seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell absorbs water.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that start premature germination or mould.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; open the container as seldom as possible.
Cracking the Shell
Every grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can drown.
- Move them to a damp paper towel within a closed container, or straight into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds produce a taproot inside two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently 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 middleman of unknown stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
- 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 kept. Seeds left in a warm warehouse for a year drop viability before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be spelled out up front.
- Breeder transparency. A good seller names the breeder for every strain. Bud Weed Seeds stocks lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder shown on each product page.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the label.
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 request needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies widely by country. In many European countries seeds are traded legally as souvenirs or for hemp purposes, while germinating them stays illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
Why did a seed fail to sprout?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds germinate well for two to three years and often far longer. Left in a warm drawer, viability falls sharply within a year.
Are autoflowering seeds weaker?
Modern autos are far closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency in good lines is comparable.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, ridges or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
