Every 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 develop. 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 distinguishes a good seed from a poor one, and how to store and germinate them correctly.

Anatomy of a Seed

A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Viable seeds are typically brown, grey or mottled, solid to the touch and slightly 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 one-off combination of its two parents, which is why two seeds from the same pack can turn out noticeably different. Breeders reduce that variation by working a line over many generations, but some range is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds trade that certainty for vigour, a strong taproot and the chance of a standout plant.

Three Seed Types, Three Different Grows

Nearly every seed on sale falls into 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, but they require identifying and removing males before they pollinate the females.
• 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 lost space of male plants.
• Autoflowering seeds contain ruderalis genetics that cause 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 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 rare.

The Case for Feminized (and the Exceptions)

For the bulk 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 entirely.

Regular seeds earn their place in a few situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population often prefer the broader genetic spread of regular stock. And some old-school lines are only available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.

Why Autos Behave Differently

Photoperiod plants remain in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That hands the grower control: 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 stay 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 stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given 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 useful than the strain name.

• 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 growth habit far better than any marketing text.
• Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
• THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a promise.
• Yield estimates. Given per square metre indoors or per plant outdoors, and strongly dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.

Telling Live Seeds From Dead Ones

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

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

Keeping Seeds Alive in the Drawer

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

• Keep them dry. A sealed container with a desiccant packet prevents 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 damaging it; the freezer is dangerous unless the seeds are fully dried.
• Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.
• Keep them still. Shifting seeds between warm and cold again and again does more damage than either condition on its own; take out the container as rarely as possible.

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. Soak the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can drown.
2. Move them to a moist paper towel within a closed container, or directly into a small pot of light, damp medium. Keep the temperature comfortably warm.
3. Wait. Most seeds produce 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, shallowly, and give gentle light once the seedling breaks the surface.

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

Vetting the Seller

Genetics are only as good as the supplier, and the difference between a reputable 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. Flexible pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
• Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability long before they reach you.
• Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be stated up front.

What Happens After Checkout

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

Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of arrival when germinated as described above, Bud Weed Seeds sends a replacement for it. The request 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 countries seeds are sold 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 import of cannabis seeds is restricted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.

Quick Answers

Does Bud Weed Seeds sell CBD-only strains?

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

How long do cannabis seeds stay viable?

Kept cool, dark and dry, most seeds sprout reliably for two to three years and frequently much longer. Left in a warm drawer, viability falls sharply within a year.

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 similar.
