Every cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of lost 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 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-shelled embryo wrapped 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 begin: a root tip, two cotyledon leaves and a store 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 different. Breeders narrow that variation by working a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds trade that certainty for vigour, a 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 first decision a buyer makes.
- Regular seeds give 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 mean 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 eliminate the guesswork and the wasted space of male plants.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of imperfect 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 description usually says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the bulk 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 missed male can seed an entire room. Feminized seeds sidestep that problem 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 frequently prefer the wider genetic spread of regular stock. And some traditional lines are simply 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 falls to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, usually 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 long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers after maximum yield from a fixed footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Read them as a ceiling, not a promise.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing copy.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- Surface. A faint waxy sheen is normal. Cracks, dents or visible mould disqualify a seed.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that collapse easily are non-viable.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The enemies are warmth, light, moisture and fluctuation.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that start premature germination or mould.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as rarely as possible.
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 no more than a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel within a closed container, or straight into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. 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 provide gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently 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 middleman of unknown stock shows up in germination rates, not on the website.
- Pack options. Multiple pack sizes allow you to test 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 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 shown on each product page.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched 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 as described above, Bud Weed Seeds sends a replacement for it. The request 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 sharply by country. In many European countries seeds are traded legally as souvenirs or for hemp 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 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 taken as legal advice.
Quick Answers
Why did a seed fail to sprout?
The most frequent causes are too long in water, low temperatures, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
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, as well as balanced and THC-dominant strains.
Are autoflowering seeds weaker?
Modern autos are much closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency in good lines is comparable.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently 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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
