Every cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds 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 across the industry. 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 germinate them properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically brown, grey or tiger-striped, solid 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 nutrients 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 grow noticeably different. Breeders narrow that variation by stabilising a line over many generations, but some range is normal 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
Nearly 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 about equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they require identifying and culling males before they pollinate the females.
- Autoflowering seeds contain ruderalis genetics that cause 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.
- 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.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, light and weeks spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population often prefer the broader genetic spread of regular stock. And some traditional 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 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 the decision: vegetate for two weeks or two months, train the plant, then flip flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a clock set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants remain small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers after maximum yield from a given footprint usually choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- 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. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few signs are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Size. Larger is not a quality marker; 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 harvested too early and rarely sprout.
- Surface. A faint waxy sheen is typical. Cracks, dents or visible 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.
Long-Term Seed Storage
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 change.
- 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.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that start premature germination or mould.
- 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 fully dried.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
The First Five Days
Each grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can drown.
- Move them to a moist paper towel within a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls the seedling for good.
Where the Seeds Come From Matters
Seeds 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, not on the website.
- Pack options. Multiple pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- 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.
- 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.
Delivery, Packaging and Replacements
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 outside.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of arrival when germinated as described above, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are traded legally as souvenirs or for agricultural 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 ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Why did a seed fail to germinate?
The most frequent causes are too long in water, cold, 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.
Are autoflowering seeds weaker?
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.
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, as well as balanced and THC-dominant strains.
How long do cannabis seeds last?
Kept cool, dark and dry, the majority of seeds germinate well for two to three years and frequently much longer. Left in a warm drawer, viability drops sharply within a year.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
