Every cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves 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.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically brown, grey or mottled, solid to the touch and a little glossy. Inside sits everything the plant needs to start: 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, and that is why two seeds from the same pack can turn out noticeably unalike. 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 exact copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
Nearly 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 cause the plant to flower 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.
- Regular seeds produce male and female plants in about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they mean identifying and culling males before they pollinate the females.
- Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the lost space of male plants.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description normally 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 space, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population often prefer the wider genetic spread of regular stock. And some old-school lines are simply available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
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, train the plant, then trigger flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers after maximum yield from a given footprint generally prefer photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more informative than the strain name.
- 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.
- 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 follows.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent 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 controlled conditions. Read them as a ceiling, not a guarantee.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few indicators are worth knowing.
- Size. Bigger 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 usually mature. Pale green or white seeds were harvested too early and seldom sprout.
- Float test. Placing seeds in water and rejecting floaters is common but crude: healthy seeds often float until the shell takes on water.
- Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
- 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 swings that trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; open the container as seldom as possible.
The First Five Days
Each grower has a favourite method, but the requirements are the same whichever you choose: 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 inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. 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, just below the surface, 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 permanently.
Reputable Source, Reliable Sprouts
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a middleman of unknown stock appears in germination rates, not on the website.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be spelled out in plain language.
- 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.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
From Checkout to Letterbox
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.
Seeds come with a germination guarantee: if any seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The request 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 sharply by country. In many European jurisdictions seeds are traded legally as souvenirs or for hemp 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 not permitted. 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
Why did a seed fail to sprout?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during transplanting. Truly dead seeds are less common than mistakes in the process.
Can I tell the sex of a seed by examining 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, determines the sex.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, marked 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.
Are autoflowering seeds weaker?
Modern 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 similar.
