Every cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of wasted effort later. The market has grown 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 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 usually brown, grey or mottled, solid to the touch and a little 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, and that is why two seeds from the same pack can turn out noticeably unalike. Breeders reduce that variation by stabilising 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 first decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they mean identifying and culling males before they pollinate the females.
- Feminized seeds are bred to produce 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.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower 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 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 thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic spread of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants remain 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 flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, typically 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 downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, outdoor 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.
- 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.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.
- 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.
- THC and CBD ranges. Quoted figures are from the breeder’s own 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 reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
Telling Live Seeds From Dead Ones
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 usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
- Float test. Dropping seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell takes on water.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; take out the container as rarely as possible.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are bone dry.
Getting a Taproot
Every grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can suffocate.
- Move them to a moist paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot within two to five days; some take a week or more.
- 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 breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stops the seedling for good.
Reputable Source, Reliable Sprouts
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of uncertain stock shows up in germination rates, rather than on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated up front.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
- Breeder transparency. A trustworthy seller names 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 named on each product page.
- Pack options. Flexible 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.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.

Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the label.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of arrival when started by the recommended method, Bud Weed Seeds replaces it. The request requires the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it differs widely by country. In many European jurisdictions 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 ownership of seeds alone is banned.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Are autoflowering seeds weaker?
Current 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.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and frequently far longer. Left in a warm drawer, viability drops noticeably within a year.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
