Any cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of wasted effort later. The market has grown 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 distinguishes a good seed from a poor one, and how to store and start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically brown, grey or mottled, firm to the touch and slightly 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, and that is why two seeds from the same pack can grow noticeably different. Breeders reduce that variation by stabilising a line over many generations, but some spread is expected 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 exceptional plant.
Three Seed Types, Three Different Grows
Almost 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 yield female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.
- Regular seeds give 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 mean identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
For the bulk of buyers the answer is feminized. If the goal 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 avoid that problem entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population often prefer the wider 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 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, shape the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers after maximum yield from a fixed footprint usually choose 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. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal conditions. Read them as a ceiling, not a guarantee.
- 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 follows.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
- 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.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Surface. A faint waxy sheen is normal. Splits, dents or obvious mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept 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 holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that start 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 preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Place 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 damp paper towel within a closed container, or directly into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce 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, shallowly, and provide gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stops the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock appears in germination rates, rather than on the website.
- 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.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
- Breeder transparency. A good seller names 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 up front.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in discreet packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if any seed fails to sprout within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The claim requires the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them stays illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate well for two to three years and frequently much longer. Kept in a warm drawer, viability drops sharply 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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
Why did a seed fail to sprout?
The commonest causes are too long in water, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
