Any cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how large 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 across the industry. 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 germinate them properly.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Viable seeds are usually brown, grey or tiger-striped, solid to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of nutrients to power the first days of growth.
Genetically, each seed is a unique combination of its two parents, and that is why two seeds from the same pack can grow noticeably different. Breeders reduce that variation by working 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 falls into 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 flower on age rather than on light cycle. They are more compact, faster and more tolerant of less-than-ideal conditions, usually at the cost of yield and potency.
- Regular seeds give male and female plants in about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, but they mean identifying and removing males before they pollinate the females.
- Feminized seeds are bred to produce female plants almost every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the majority 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 discarded, and a single missed male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population frequently prefer the wider genetic variation 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.
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 drops to around twelve hours. That gives the grower control: veg for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers ignore the light schedule and flower 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 long light from start to finish. The trade-off 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 after maximum yield from a fixed footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and much 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. Treat them as a ceiling, not a promise.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing text.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent 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.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
- Surface. A slight waxy sheen is normal. Cracks, dents or visible mould rule out a seed.
- 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.
- Float test. Dropping seeds in water and discarding floaters is common but unreliable: fresh seeds often float until the shell takes on water.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- 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 fully dried.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either condition on its own; take out the container as seldom as possible.
The First Five Days
Each grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can suffocate.
- Move them to a moist paper towel inside a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- 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 give gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls the seedling for good.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Breeder transparency. A trustworthy seller names 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 shown on each product page.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out in plain language.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The claim needs 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 differs widely by country. In many European jurisdictions seeds are sold legally as souvenirs or for agricultural purposes, while germinating them stays illegal. Elsewhere both buying and growing are permitted 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 duty to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently far longer. Kept in a warm drawer, viability falls noticeably within a year.
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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
Why did a seed fail to sprout?
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 handling. Truly dead seeds are rarer than mistakes in the process.
Are autoflowering seeds less potent?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency from reputable breeders is comparable.
