Any cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide explains 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 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, which is why two seeds from the same pack can grow 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 identical copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
The First Decision: Seed Type
Nearly 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 cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
- 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, but they require 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 lost space of male plants.
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.
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 time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds justify their place in a few situations. Breeders need males for 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 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 stay 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 clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Translating the Product Page
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- 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 dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing text.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under ideal conditions. Treat them as a ceiling, not a promise.
A Quick Viability Check
Appearance is a rough guide to viability, not a verdict, but a few indicators 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 better; seed size varies by strain, and some excellent genetics make small seeds.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Shell. A firm shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Surface. A slight waxy sheen is typical. Cracks, dents or visible mould rule out a seed.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either condition on its own; take out the container as seldom as possible.
- Keep them cool. A steady 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 opaque container beats a clear one.
Cracking the Shell
Each grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can drown.
- Move them to a damp paper towel inside a closed container, or straight into a small 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 take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and give gentle light as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one often stops the seedling permanently.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a serious seed bank and a reseller of unknown stock appears in germination rates, rather than on the website.
- Pack options. Multiple pack sizes let you to try a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A good seller lists 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.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be stated up front.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in discreet packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds replaces it. The claim needs 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 varies widely by country. In many European jurisdictions seeds are traded legally as souvenirs 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 possession of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
Are autoflowering seeds less potent?
Modern autos are far closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency in good lines is similar.
Can I tell the sex of a seed by looking at 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 show preflowers, determines the sex.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
How long do cannabis seeds last?
Kept cool, dark and dry, most seeds sprout well for two to three years and often far longer. Kept in a warm drawer, viability drops noticeably within a year.
Why did a seed fail to sprout?
The most frequent 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 mistakes in the process.
