Every cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it reacts to light, how large 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 grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. 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 start them properly.
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 mottled, firm to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store of nutrients to fuel 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 spread is normal in any seed-grown crop. Clones are the only way to get exact 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 first decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, faster and more forgiving of imperfect conditions, usually at the cost of yield and potency.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they mean identifying and culling males before they pollinate the females.
- 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 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.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the goal 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 three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population often prefer the broader genetic spread 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 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 the decision: veg for two weeks or two months, shape the plant, then trigger 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 remain small, and they can be run under long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint usually choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Read them as a ceiling, not a guarantee.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Surface. A faint waxy sheen is typical. Splits, dents or visible mould disqualify a seed.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Shell. A firm shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are dead.
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 warmth, light, moisture and fluctuation.
- Keep them dry. A airtight 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 cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either temperature on its own; take out the container as rarely as possible.
Getting a Taproot
Each grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can drown.
- Move them to a moist paper towel inside a closed container, or straight into a starter pot of light, moist 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 reaches about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling for good.
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 uncertain stock shows up in germination rates, rather than on the website.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated up front.
- Pack options. Flexible pack sizes let you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
Delivery, Packaging and Replacements
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 outside.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is separate from the law on cannabis itself, and it varies widely by country. In many European jurisdictions seeds are traded legally as souvenirs or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are allowed under licence or within personal limits, and in some countries possession of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is restricted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
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 injury to the taproot during handling. Genuinely dead seeds are rarer than mistakes in the process.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Kept in a warm drawer, viability falls noticeably within a year.
Are autoflowering seeds weaker?
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 in good lines is similar.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
