Every cannabis plant starts as a seed, and the seed settles 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 develop. Choosing well at this stage avoids months of lost effort later. The market has grown 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.
What You Are Actually Buying
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, firm to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store of energy 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 turn out 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 exact copies; seeds trade that certainty for vigour, a strong taproot and the chance of a exceptional plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, typically at the cost of yield and potency.
- Regular seeds produce male and female plants in about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they require identifying and removing 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 label usually says so. Regular autoflowering seeds exist but are uncommon.
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 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 entirely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population often prefer the broader genetic spread of regular stock. And some old-school lines are only 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 stay in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That hands the grower control: veg for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants remain small, and they can be grown under long light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers after maximum yield from a given footprint generally 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 informative than the strain name.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder uses.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under ideal conditions. Treat them as a ceiling, not a promise.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point 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. Use them to compare strains from the same breeder, not across breeders.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that collapse easily are dead.
- Size. Larger is not better; 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 seldom sprout.
- Surface. A slight waxy sheen is normal. Splits, dimples or obvious mould rule out a seed.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The threats are heat, 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; open the container as rarely as possible.
- Keep them cool. A constant temperature in the fridge range slows 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 opaque container beats a clear one.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that trigger premature germination or mould.
Getting a Taproot
Every grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can drown.
- Move them to a damp paper towel within a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Leave them. 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, shallowly, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stalls the seedling for good.
Where the Seeds Come From Matters
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.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be stated up front.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Breeder transparency. A trustworthy 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 shown on each product page.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet 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 request needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European countries seeds are sold legally as souvenirs or for agricultural purposes, while germinating them remains illegal. Elsewhere both buying and growing are permitted under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where import 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
Why did a seed fail to sprout?
The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during transplanting. Genuinely dead seeds are less common than mistakes in the process.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges 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.
Are autoflowering seeds less potent?
Current autos are far 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 last?
Stored cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Left in a warm drawer, viability drops noticeably within a year.
