Every cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the mix 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 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 start them properly.
Anatomy of a Seed
A cannabis seed is a small, 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 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 identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
Regular, Feminized, Autoflowering: The Big Three
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 about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they mean identifying and removing males before they pollinate the females.
- Feminized seeds are bred to yield 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 make the plant to flower on age rather than on light cycle. They are smaller, faster and more tolerant of less-than-ideal conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the goal is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single missed male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn 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 broader genetic variation 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 drops to around twelve hours. That gives the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers ignore 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 much shorter, the plants remain small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a given 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 informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- 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.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a guarantee.
- Lineage. The parent strains tell you what to expect in smell, structure and growth habit far better than any marketing copy.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Surface. A faint waxy sheen is normal. Cracks, dents or obvious mould disqualify a seed.
- Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: healthy seeds often float until the shell absorbs water.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either condition on its own; open the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
The First Five Days
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can drown.
- Move them to a moist paper towel inside a closed container, or straight into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds produce a taproot within two to five days; some need 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 breaks easily and a damaged one often stops the seedling permanently.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of unknown stock appears in germination rates, not on the website.
- Pack options. Multiple pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A good 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.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
- Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be spelled out up front.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds sends a replacement for it. The request requires the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is distinct 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 an offence. Elsewhere both buying and growing are permitted under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. 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
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and frequently far longer. Left in a warm drawer, viability falls noticeably within a year.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you 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.
Are autoflowering seeds weaker?
Modern autos are far closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency in good lines is similar.
Why did a seed fail to germinate?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than mistakes in the process.
