Every cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide explains the main seed types, how to read a strain description, what distinguishes 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 small, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually 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 reserve of energy to power the first days of growth.
Genetically, each seed is a unique combination of its two parents, and that is why two seeds from the same pack can turn out noticeably unalike. Breeders narrow that variation by working a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get identical copies; seeds trade that certainty for vigour, a taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, usually 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.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to make their own seeds, but they require identifying and culling males before they pollinate the females.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue entirely.
Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic variation of regular stock. And some traditional lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Why Autos Behave Differently
Photoperiod plants remain in vegetative growth as long as they get long days and switch to flowering when the light drops to around twelve hours. That hands the grower control: vegetate 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, typically a few weeks after sprouting. The whole run 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 stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing copy.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily 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 usually given as total time from seed. Confirm which convention the breeder follows.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Surface. A slight waxy sheen is normal. Cracks, dimples or obvious mould disqualify a seed.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that crush easily are dead.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: healthy seeds often float until the shell takes on water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either condition on its own; open the container as rarely as possible.
The First Five Days
Each grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- 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 inside a closed container, or directly into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show 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 provide gentle light as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one often stalls the seedling for good.
Where the Seeds Come From Matters
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.
- Breeder transparency. A trustworthy 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 shown on each product page.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out in plain language.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Pack options. Multiple pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the outside.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains an offence. Elsewhere 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 importing 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.
Questions Growers Ask
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 transplanting. Genuinely dead seeds are rarer than mistakes in the process.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds sprout reliably for two to three years and often much longer. Left in a warm drawer, viability drops sharply within a year.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Are autoflowering seeds less potent?
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 from reputable breeders is comparable.
