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 balance of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 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 start them correctly.

Anatomy of a Seed

A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are usually brown, grey or mottled, solid to the touch and slightly glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store 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 narrow that variation by stabilising a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.

Regular, Feminized, Autoflowering: The Big Three

Nearly every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.

• Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, quicker and more tolerant of imperfect conditions, usually at the cost of yield and potency.
• Feminized seeds are bred to produce female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the lost space of male plants.
• Regular seeds give male and female plants in about 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 mutually exclusive: 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 bulk 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 sidestep that problem 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 often prefer the wider 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 stay in vegetative growth as long as they receive long days and switch 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 fits the space.

Autoflowers ignore the light schedule and bloom on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be grown under long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a fixed footprint usually prefer 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.

• THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
• Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
• Lineage. The parent strains tell you what to expect in smell, structure and growth habit far better than any marketing text.
• Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.

Signs of a Healthy Seed

Appearance is a rough guide to viability, not a test, but a few signs are reliable.

• Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
• Float test. Placing seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell absorbs water.
• Surface. A faint waxy sheen is normal. Splits, dents or obvious mould disqualify a seed.
• Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics make small seeds.
• Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.

Cool, Dark, Dry, Still

Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The threats are warmth, light, moisture and fluctuation.

• Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
• Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
• Keep them still. Shifting seeds between warm and cold again and again does more harm than either condition on its own; open the container as rarely as possible.
• 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 bone dry.

The First Five Days

Every grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.

1. Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can suffocate.
2. Move them to a moist paper towel within a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
3. Wait. Most seeds show a taproot within two to five days; some take a week or more.
4. Once the taproot is about a centimetre long, plant it root-down, shallowly, and give gentle light as soon as 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 for good.

Where the Seeds Come From Matters

Genetics 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, rather than on the website.

• Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be stated up front.
• Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
• Breeder transparency. A good 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 shown on each product page.
• 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.

From Checkout to Letterbox

Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no reference to the contents on the outside.

Every pack comes with a germination guarantee: if any seed fails to sprout within 14 days of arrival when started as described above, Bud Weed Seeds sends a replacement for it. The claim requires 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 differs sharply by country. In many European countries seeds are traded legally as collectors’ items or for hemp 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 prohibited.

Bud Weed Seeds does not ship 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 jurisdiction before ordering, and nothing on this page should be read as legal advice.

Still Wondering?

Does Bud Weed Seeds stock CBD-only strains?

Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.

Can I tell the sex of a seed by examining it?

No. Claims based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.

How long do cannabis seeds stay viable?

Stored cool, dark and dry, most seeds sprout well for two to three years and frequently much longer. Kept in a warm drawer, viability drops noticeably within a year.

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.

Are autoflowering seeds less potent?

Modern autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
