Every cannabis plant starts as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance of cannabinoids and terpenes it can develop. 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 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 correctly.

One Seed, One Genetic Lottery Ticket

A cannabis seed is a tiny, 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 start: 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, which 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 expected 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.

The First Decision: Seed Type

Nearly every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.

• Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the lost space of male plants.
• Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, faster and more forgiving of less-than-ideal conditions, typically at the cost of yield and potency.
• Regular seeds produce 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 removing males before they pollinate the females.

Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are rare.

Males: Asset or Liability?

For the majority of buyers the answer is feminized. If the goal is flower, every male plant is room, light and time 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 earn their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic spread of regular stock. And some traditional lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.

Photoperiod Control vs. Autoflower Speed

Photoperiod plants stay in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, train the plant, then flip flowering when it fits the space.

Autoflowers ignore 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 shorter, the plants remain small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers after maximum yield from a given footprint generally 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 useful than the strain name.

• Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
• Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing copy.
• 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.
• Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.

Signs of a Healthy Seed

Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.

• Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
• Size. Larger is not better; seed size varies by strain, and some top genetics make small seeds.
• Float test. Placing seeds in water and rejecting floaters is popular but crude: healthy seeds often float until the shell takes on water.
• Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
• Surface. A slight waxy sheen is typical. Splits, dimples or obvious mould rule out a seed.

Cool, Dark, Dry, Still

Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The threats are warmth, light, moisture and change.

• 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 slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are bone dry.
• Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
• Keep them still. Moving seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as rarely as possible.

The First Five Days

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

1. Soak 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 inside a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
3. Leave them. Most seeds show a taproot inside two to five days; some take a week or more.
4. Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and give gentle light as soon as the seedling emerges from the surface.

Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one often stalls the seedling for good.

Vetting the Seller

Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of uncertain stock appears in germination rates, rather than on the website.

• 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.
• 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, discretion, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
• Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.

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 outside.

Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of arrival when started by the recommended method, Bud Weed Seeds replaces it. The request needs the order number and, in most cases, a photo.

Before You Order: The Rules

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 traded legally as collectors’ items or for hemp purposes, while germinating them remains illegal. In other places both buying and growing are permitted 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 restricted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.

Still Wondering?

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

No. Methods based on shape, ridges or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.

Are autoflowering seeds weaker?

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

How long do cannabis seeds stay viable?

Kept cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently far longer. Left in a warm drawer, viability falls noticeably within a year.

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, as well as balanced and THC-dominant strains.
