Any cannabis plant starts as a seed, and the seed settles 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 develop. Choosing well at this stage avoids months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. 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 start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm 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 unalike. Breeders reduce that variation by working a line over many generations, but some range is normal in any seed-grown crop. Clones are the only way to get exact copies; seeds trade that certainty for vigour, a strong taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
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 cause the plant to flower on age rather than on light cycle. They are more compact, quicker and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- 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, but 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 remove 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 description normally says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem entirely.
Regular seeds justify their place in three 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 traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Why Autos Behave Differently
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 hands the grower the decision: veg for two weeks or two months, shape the plant, then flip flowering when it fits 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 shorter, the plants stay small, and they can be run under continuous 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 tend to do well with autos; growers after maximum yield from a given footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- 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.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- Yield estimates. Given 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.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing text.
A Quick Viability Check
Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics make small seeds.
- Surface. A faint waxy sheen is typical. Splits, dimples or visible mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is common but crude: 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 kept properly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
The First Five Days
Each grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- Place 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 damp paper towel within a closed container, or straight into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show a taproot inside two to five days; some need a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and give gentle light as soon as the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one often stops the seedling for good.
Reputable Source, Reliable Sprouts
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a reseller of unknown stock appears in germination rates, not on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be spelled out in plain language.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Pack options. Multiple pack sizes let you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
What Happens After Checkout
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.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The claim 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 widely by country. In many European jurisdictions seeds are sold legally as collectors‘ items or for hemp purposes, while germinating them remains illegal. In other places both buying and growing are allowed under licence or within personal limits, and in some countries possession of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, markings or the scar 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 stock CBD-only strains?
Yes. The catalogue has high-CBD lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
Are autoflowering seeds weaker?
Modern autos are much closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency in good lines is similar.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout well for two to three years and often far longer. Left in a warm drawer, viability drops noticeably within a year.
