Every cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds to light, how large it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted 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-shelled embryo enclosed in a protective coat. Viable seeds are usually brown, grey or mottled, solid to the touch and a little 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 unique combination of its two parents, which 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 exact copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
Almost every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Regular seeds produce male and female plants in about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, but they require identifying and culling males before they pollinate the females.
- Feminized seeds are bred to produce female plants almost 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 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.
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.
Males: Asset or Liability?
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is space, light and time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue 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 frequently prefer the wider genetic variation 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.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants remain in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, shape the plant, then flip flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants stay small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a given footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more informative than the strain name.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal conditions. Read them as a ceiling, not a guarantee.
- 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 strongly reliant on the grower. Use 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.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few indicators are reliable.
- Surface. A faint waxy sheen is normal. Cracks, dents or visible mould rule out a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that collapse easily are dead.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Float test. Placing seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell takes on water.
Cool, Dark, Dry, Still
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The threats are heat, light, moisture and change.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either condition on its own; take out the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
Getting a Taproot
Each grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show 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, shallowly, and provide gentle light as soon as the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls the seedling permanently.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock shows up in germination rates, not on the website.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be spelled out up front.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Breeder transparency. A trustworthy 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.
- Pack options. Flexible pack sizes allow you to try a strain before committing; Bud Weed Seeds offers 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 dispatched in discreet 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 arrival when germinated by the recommended method, Bud Weed Seeds replaces it. The claim 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 widely by country. In many European jurisdictions seeds are traded legally as collectors‘ items or for hemp purposes, while germinating them stays an offence. Elsewhere 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 importing of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
Does Bud Weed Seeds sell 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.
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 damage to the taproot during transplanting. Truly dead seeds are less common than mistakes in the process.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, markings or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Are autoflowering seeds less potent?
Current autos are much 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 comparable.
How long do cannabis seeds last?
Kept cool, dark and dry, most seeds sprout well for two to three years and often far longer. Left in a warm drawer, viability drops sharply within a year.
