Every cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Viable seeds are typically brown, grey or mottled, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of nutrients to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, which 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 range 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.
The First Decision: Seed Type
Nearly every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Feminized seeds are bred to yield 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.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of less-than-ideal conditions, usually at the cost of yield and potency.
- Regular seeds produce male and female plants in about equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they require identifying and removing males before they pollinate the females.
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.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the aim 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 justify their place in a few situations. Breeders need males to provide 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 traditional lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, train the plant, then trigger 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 cycle from seed to harvest is much shorter, the plants stay small, and they can be run under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more useful than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- 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.
- 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.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a test, but a few signs are worth knowing.
- Surface. A slight waxy sheen is typical. Cracks, dimples or visible mould disqualify a seed.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell absorbs water.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- 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. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; take out the container as rarely as possible.
- 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 changes that start premature germination or mould.
Cracking the Shell
Each grower has a favourite method, but the requirements are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can drown.
- Move them to a moist paper towel inside a closed container, or directly into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show a taproot inside two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stalls the seedling permanently.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a serious seed bank and a reseller of unknown stock appears in germination rates, rather than on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out up front.
- Breeder transparency. A trustworthy 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.
- Pack options. Flexible 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.
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 sprout within 14 days of arrival when started by the recommended method, Bud Weed Seeds replaces 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 varies sharply by country. In many European countries seeds are traded legally as collectors‘ items or for agricultural purposes, while germinating them remains illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership 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 responsibility to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency from reputable breeders is comparable.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds sprout reliably for two to three years and often much longer. Left in a warm drawer, viability drops noticeably within a year.
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 damage to the taproot during transplanting. Truly dead seeds are rarer than grower error.
