Any cannabis plant starts 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 mix 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 germinate them correctly.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically brown, grey or tiger-striped, firm to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of energy to fuel 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 turn out noticeably unalike. 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 identical copies; seeds trade that certainty for vigour, a taproot and the chance of a exceptional 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.
- 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 wasted 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 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 imperfect conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description normally says so. Regular autoflowering seeds exist but are uncommon.
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 space, light and weeks spent on something that will be discarded, and a single missed male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Light-Driven or Clock-Driven?
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: vegetate 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 clock set by genetics, usually 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 trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint usually choose 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 informative than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Expressed 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.
- 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 aroma, 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. Confirm which convention the breeder follows.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Surface. A slight waxy sheen is normal. Splits, 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 seldom sprout.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Float test. Placing seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell takes on water.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The threats are heat, light, moisture and change.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
- Keep them dry. A airtight 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; open the container as seldom as possible.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
Cracking the Shell
Every grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- 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 within a closed container, or straight into a starter pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. 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 provide gentle light as soon as the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling for good.
Vetting the Seller
Seeds are only as good as the supplier, and the difference between a serious seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.
- Pack options. Flexible pack sizes let you to test a strain before committing; 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 spelled out in plain language.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability long before they reach you.
What Happens After Checkout
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 a seed fails to germinate within 14 days of arrival when germinated as described above, Bud Weed Seeds sends a replacement for it. The request 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 sharply by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains an offence. 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 not permitted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Why did a seed fail to germinate?
The commonest 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 mistakes in the process.
Are autoflowering seeds less potent?
Modern autos are much closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is comparable.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, ridges 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.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
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. Kept in a warm drawer, viability falls sharply within a year.
