Any cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts 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 now carries 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 embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, solid 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 power 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 different. Breeders narrow that variation by stabilising 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 taproot and the chance of a standout plant.
The First Decision: Seed Type
Almost every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to produce 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 produce male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they require identifying and culling males before they pollinate the females.
Feminized and autoflowering are not opposites: 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 missed male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population often prefer the broader 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.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants remain in vegetative growth as long as they get long days and switch 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 timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a fixed footprint generally prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and most of it is more useful 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.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house 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 growth habit far better than any marketing text.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: fresh seeds often float until the shell absorbs water.
- Size. Larger is not better; seed size varies by strain, and some top genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are dead.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The enemies are warmth, 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 dangerous unless the seeds are fully dried.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that start premature germination or mould.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as seldom as possible.
The First Five Days
Each grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a moist paper towel inside a closed container, or directly into a starter pot of light, moist 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, just below the surface, 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 damaged 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 reputable seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Pack options. Multiple pack sizes allow 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 trustworthy seller lists 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. Ask how stock is stored. Seeds left in a warm warehouse for a year lose viability long before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no reference to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds sends a replacement for it. The claim needs the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies widely by country. In many European countries seeds are sold legally as souvenirs or for hemp purposes, while germinating them remains illegal. Elsewhere 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 restricted. It is the buyer’s responsibility to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
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 far longer. Left in a warm drawer, viability drops noticeably within a year.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, ridges or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Are autoflowering seeds weaker?
Modern autos are far 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.
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 injury to the taproot during handling. Truly dead seeds are less common than grower error.
