Any cannabis plant begins 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 produce. Choosing well at this stage saves months of wasted 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 properly.

One Seed, One Genetic Lottery Ticket

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 start: a root tip, two cotyledon leaves and a reserve of nutrients 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 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 exact copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.

Three Seed Types, Three Different Grows

Almost 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 cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
• Regular seeds give male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, but they mean identifying and removing males before they pollinate the females.
• Feminized seeds are bred to produce 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.

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 uncommon.

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 avoid that problem completely.

Regular seeds earn their place in three situations. Breeders need males for pollen. Growers who want to select a keeper from a large population often prefer the wider genetic spread of regular stock. And some traditional lines are only sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.

Why Autos Behave Differently

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 control: vegetate 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 timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants remain small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a given footprint usually choose photoperiod stock.

Numbers on the Pack, Explained

A seed listing packs a lot of information into a few lines, and much of it is more informative than the strain name.

• Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
• Yield estimates. Given 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.
• 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.
• 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.

A Quick Viability Check

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

• Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
• Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
• Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that collapse easily are non-viable.
• Float test. Dropping seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell absorbs water.
• Surface. A faint waxy sheen is typical. Splits, dimples or obvious mould disqualify a seed.

Cool, Dark, Dry, Still

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

• Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
• 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 damage than either temperature on its own; open the container as seldom as possible.
• Keep them dry. A airtight container with a desiccant packet stops the humidity swings that trigger premature germination or mould.

Getting a Taproot

Each 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 drown.
2. Move them to a moist paper towel within a closed container, or straight 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 provide gentle light as soon as the seedling breaks the surface.

Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stalls the seedling permanently.

Reputable Source, Reliable Sprouts

Genetics 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.

• Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
• Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be stated up front.
• Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.
• Breeder transparency. A good seller lists 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.

What Happens After Checkout

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

Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when germinated as described above, Bud Weed Seeds sends a replacement for 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 countries seeds are sold legally as collectors’ items 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 banned.

Bud Weed Seeds does not ship to the United States, where importing 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.

Questions Growers Ask

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 show preflowers, determines the sex.

How long do cannabis seeds stay viable?

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

Does Bud Weed Seeds sell 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.

Are autoflowering seeds weaker?

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 comparable.
