Any cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts to light, how large it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of lost effort later. The market has grown enormously, and https://budweedseeds.com now carries 400 strains from breeders around the world. 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 properly.
What You Are Actually Buying
A cannabis seed is a small, hard embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, firm 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 one-off combination of its two parents, and that is why two seeds from the same pack can turn out noticeably different. Breeders narrow that variation by stabilising a line over many generations, but some range is expected in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a taproot and the chance of a exceptional 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.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they mean 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 lost space of male plants.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are more compact, faster and more tolerant 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 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 weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that problem entirely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant 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.
Why Autos Behave Differently
Photoperiod plants remain in vegetative growth as long as they receive long days and switch to flowering when the light falls 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 ignore 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 stay 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 stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing 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 much of it is more useful than the strain name.
- 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.
- 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.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing copy.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder follows.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a verdict, but a few signs are reliable.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Surface. A faint waxy sheen is typical. Cracks, dents or obvious mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Bigger is not a quality marker; 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 absorbs water.
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 heat, light, moisture and fluctuation.
- 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 dry. A sealed container with a desiccant packet stops the humidity swings that start premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either temperature on its own; take out the container as seldom as possible.
Getting a Taproot
Each grower has a favourite method, but the requirements are the same in all of them: 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, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show a taproot within two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stops the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the source, and the difference between a serious seed bank and a reseller of uncertain stock shows up in germination rates, not on the website.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
- 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 named on each product page.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
From Checkout to Letterbox
Bud Weed Seeds ships 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 any seed fails to germinate within 14 days of arrival when started by the recommended method, Bud Weed Seeds sends a replacement for it. The claim requires 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 varies widely by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
Are autoflowering seeds weaker?
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 similar.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and often far longer. Left in a warm drawer, viability drops noticeably within a year.
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.
Why did a seed fail to germinate?
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 transplanting. Truly dead seeds are rarer than grower error.
