Any 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 produce. Choosing well at this stage avoids months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders across the industry. 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature 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 energy to power the first days of growth.
Genetically, each seed is a one-off combination of its two parents, and that is why two seeds from the same pack can grow noticeably different. Breeders reduce that variation by working a line over many generations, but some spread is normal 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 exceptional plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to produce 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.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they mean identifying and culling males before they pollinate the females.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population often prefer the wider genetic variation of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Photoperiod Control vs. Autoflower Speed
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 the decision: veg for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants remain small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a fixed footprint generally 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.
- 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.
- 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.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly 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.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few indicators are reliable.
- Float test. Placing seeds in water and discarding floaters is popular but crude: healthy seeds often float until the shell absorbs water.
- Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
- Surface. A faint waxy sheen is typical. Splits, dents or visible mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The threats are heat, 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 prevents the humidity changes that start premature germination or mould.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either temperature on its own; open the container as seldom as possible.
Cracking the Shell
Every grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can suffocate.
- Move them to a damp paper towel within a closed container, or straight into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stops the seedling permanently.
Reputable Source, Reliable Sprouts
Seeds are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock appears in germination rates, not on the website.
- Pack options. Multiple pack sizes allow you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated in plain language.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
- Breeder transparency. A good 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 named on each product page.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year drop viability before they reach you.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the label.
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 claim requires 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 differs widely by country. In many European countries seeds are sold 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 send orders to the United States, where importing of cannabis seeds is not permitted. 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.
Quick Answers
Are autoflowering seeds weaker?
Current autos are much 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 comparable.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds sprout well for two to three years and often far longer. Left in a warm drawer, viability drops sharply within a year.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Why did a seed fail to sprout?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are rarer than grower error.
