Every cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the balance 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 around the world. 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 start them correctly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Mature seeds are typically brown, grey or mottled, firm 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 fuel 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 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 exchange that certainty for vigour, a taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Feminized seeds are bred to yield female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
- Regular seeds produce 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 removing males before they pollinate the females.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are rare.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is space, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a mother plant from a large population often prefer the broader genetic spread of regular stock. And some old-school lines are simply 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 get long days and switch to flowering when the light drops to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be run under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most 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.
- 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 own tests under controlled conditions. Treat them as a ceiling, not a guarantee.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few signs are reliable.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that collapse easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
- Surface. A faint waxy sheen is typical. Splits, dents or obvious mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is common but crude: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
Cracking the Shell
Each grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot within 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.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling for good.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.
- 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.
- 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.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out in plain language.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose 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.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds replaces it. The request needs the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is distinct from the law on cannabis itself, and it differs sharply by country. In many European jurisdictions seeds are sold legally as souvenirs or for agricultural purposes, while germinating them stays illegal. In other places 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 duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds germinate reliably for two to three years and often far longer. Left in a warm drawer, viability falls noticeably within a year.
Are autoflowering seeds less potent?
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 similar.
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 show preflowers, tells you the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
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 transplanting. Truly dead seeds are less common than grower error.
