Every cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of lost effort later. The market has expanded 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 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 embryo wrapped in a protective coat. Viable seeds are usually brown, grey or mottled, solid to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of energy to power 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 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
Almost every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom 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 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 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.
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 overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a mother plant from a large population often prefer the wider genetic spread 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 hard to justify.
Why Autos Behave Differently
Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers disregard 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 stay 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, balcony growers and anyone with limited height tend to succeed with autos; growers chasing 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 much of it is more useful than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat 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 often given as total time from seed. Check which convention the breeder uses.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing text.
- 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.
Signs of a Healthy Seed
Appearance is a rough 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 crude: fresh 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 collapse easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes 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.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either temperature on its own; take out the container as seldom as possible.
The First Five Days
Every 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. Any longer and they can drown.
- Move them to a moist paper towel inside a closed container, or straight into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds produce 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, 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 breaks easily and a damaged one often stalls the seedling permanently.
Reputable Source, Reliable Sprouts
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock appears in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Breeder transparency. A good seller lists 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 named on each product page.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be stated up front.
- Storage on their end. Ask how stock is kept. Seeds left 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 plain packaging with no mention to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds sends a replacement for it. The claim requires 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 widely by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays illegal. Elsewhere 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 send orders to the United States, where import of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the crater 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 high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Why did a seed fail to germinate?
The most frequent causes are too long in water, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Genuinely 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 in good lines is comparable.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and often much longer. Left in a warm drawer, viability falls noticeably within a year.
