Any cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 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 properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are typically brown, grey or tiger-striped, 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 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 turn out noticeably unalike. Breeders reduce that variation by working a line over many generations, but some range 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.
Regular, Feminized, Autoflowering: The Big Three
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- 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.
- Regular seeds produce male and female plants in about equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they require identifying and culling males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, faster and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, 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 issue completely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population often prefer the broader genetic spread of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Why Autos Behave Differently
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 flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be grown 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 often do well with autos; growers chasing maximum yield from a fixed footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more informative than the strain name.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly dependent 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 hint at growth habit (height, internode spacing, flowering time) more than at effect.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are dead.
- Float test. Dropping seeds in water and rejecting floaters is common but crude: fresh seeds often float until the shell takes on water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Surface. A slight waxy sheen is typical. Cracks, dents or obvious mould rule out a seed.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- 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 risky unless the seeds are fully dried.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either condition on its own; open the container as rarely as possible.
Cracking the Shell
Every grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak 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 moist paper towel inside 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 show a taproot inside two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stalls the seedling for good.
Reputable Source, Reliable Sprouts
Seeds are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- 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 shown on each product page.
- Pack options. Flexible pack sizes let you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
- Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in discreet packaging with no mention to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of delivery 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 distinct from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are permitted under licence or within personal limits, and in some countries possession of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Why did a seed fail to germinate?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Genuinely dead seeds are less common than mistakes in the process.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and often much longer. Kept in a warm drawer, viability drops 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 generally smaller because the plants are smaller, but potency from reputable breeders is similar.
