Every cannabis plant begins as a seed, and the seed settles 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 produce. Choosing well at this stage avoids months of lost effort later. The market has grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide explains the main seed types, how to read a strain description, what separates a good seed from a poor one, and how to store and germinate them correctly.
What You Are Actually Buying
A cannabis seed is a small, hard embryo wrapped 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 nutrients 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 grow noticeably different. Breeders reduce that variation by working 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 strong taproot and the chance of a standout plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- 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 mean identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal 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 eliminate the guesswork and the wasted space of male plants.
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 rare.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the goal 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 avoid 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 often prefer the broader genetic spread of regular stock. And some old-school lines are only sold 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 receive long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: veg 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 timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants remain 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 remains stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a fixed footprint generally prefer 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.
- Yield estimates. Expressed 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- 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.
- Lineage. The parent strains tell you what to expect in smell, structure and growth habit far better than any marketing copy.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Check which convention the breeder uses.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a test, but a few indicators are worth knowing.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Surface. A slight waxy sheen is typical. Cracks, dimples or obvious mould rule out a seed.
- Float test. Placing seeds in water and rejecting floaters is common but crude: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
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 holds back the seed’s metabolism without damaging 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 is better than a clear one.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that trigger premature germination or mould.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as rarely as possible.
Getting a Taproot
Every grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. 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 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 once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stalls the seedling permanently.
Vetting the Seller
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.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be stated up front.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
- 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 named on each product page.
- Pack options. Multiple 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.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the outside.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of delivery 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 differs widely by country. In many European countries seeds are sold legally as collectors’ items or for hemp 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 banned.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
Why did a seed fail to sprout?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are less common than grower error.
How long do cannabis seeds last?
Kept cool, dark and dry, most seeds germinate reliably for two to three years and often much longer. Kept in a warm drawer, viability falls noticeably within a year.
Are autoflowering seeds weaker?
Current autos are far 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.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
