Any cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts 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 expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. This guide explains 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 correctly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Mature seeds are typically 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 reserve of nutrients 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 turn out noticeably different. Breeders narrow 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
Almost every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- 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.
- Regular seeds produce male and female plants in about equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they require identifying and culling males before they pollinate the females.
- 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 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 normally 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 space, 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 a few 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 old-school lines are only available 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 get long days and move to flowering when the light drops to around twelve hours. That gives the grower control: vegetate for two weeks or two months, train the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be run under long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers after maximum yield from a fixed footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more useful than the strain name.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing copy.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under controlled conditions. Read them as a ceiling, not a promise.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few indicators are reliable.
- Surface. A slight waxy sheen is typical. Splits, dents or obvious mould rule out a seed.
- Size. Larger 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 healthy sign; seeds that crush easily are non-viable.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- 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.
Cracking the Shell
Each grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- Place 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 moist paper towel within a closed container, or straight into a starter pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot inside two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls 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 uncertain stock appears in germination rates, rather than on the website.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
- Breeder transparency. A good seller names 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.
- 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 sealed packs, not repackaged in a plain bag.
- Pack options. Flexible 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.
From Checkout to Letterbox
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 outside.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of delivery when germinated as described above, Bud Weed Seeds replaces it. The request requires the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them stays an offence. In other places 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 send orders to the United States, where importing 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 taken as legal advice.
Questions Growers Ask
Can I tell the sex of a seed by examining it?
No. Claims 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, tells you the sex.
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout well for two to three years and frequently far longer. Left in a warm drawer, viability falls noticeably within a year.
Why did a seed fail to sprout?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Genuinely dead seeds are less common than grower error.
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, as well as balanced and THC-dominant strains.
