Any cannabis plant starts as a seed, and the seed decides more than most people 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 avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com currently lists 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 germinate them properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard embryo wrapped in a protective coat. Viable seeds are usually brown, grey or mottled, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of energy 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 grow noticeably unalike. Breeders narrow 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 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.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more forgiving of imperfect conditions, typically at the cost of yield and potency.
- 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 give 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 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 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 aim is flower, every male plant is space, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some traditional 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 switch to flowering when the light drops to around twelve hours. That hands the grower the decision: veg for two weeks or two months, train the plant, then flip flowering when it suits 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 much shorter, the plants remain small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers after 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 much of it is more informative than the strain name.
- Sativa, indica or hybrid. Today 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 measured from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Surface. A faint waxy sheen is typical. Cracks, dimples or visible mould rule out a seed.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are fully dried.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either condition on its own; open the container as rarely as possible.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that start premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.
Cracking the Shell
Each grower has a preferred 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 moist paper towel within a closed container, or straight into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. 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 once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls the seedling for good.
Where the Seeds Come From Matters
Genetics are only as good as the supplier, and the difference between a serious seed bank and a reseller of unknown stock appears in germination rates, not on the website.
- Breeder transparency. A trustworthy 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 shown on each product page.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when germinated as described above, Bud Weed Seeds sends a replacement for it. The claim needs the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it differs widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains an offence. In other places 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 import of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
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, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Are autoflowering seeds weaker?
Current 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 comparable.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout well for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply 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.
