Any 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 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 around the world. This guide covers 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 correctly.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of energy to fuel 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 narrow 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 exchange that certainty for vigour, a strong taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
Almost every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, faster and more tolerant 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 favoured by breeders and by growers who want to make their own seeds, but they mean identifying and culling 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 lost 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 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 problem entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the broader 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 hard to justify.
Why Autos Behave Differently
Photoperiod plants stay in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That gives the grower control: vegetate for two weeks or two months, train the plant, then flip flowering when it fits the space.
Autoflowers ignore the light schedule and flower on a timer 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 remains stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers after maximum yield from a fixed footprint usually choose photoperiod stock.
Translating the Product Page
A seed listing packs a lot of information into a few lines, and most of it is more informative than the strain name.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often 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.
- Lineage. The parent strains show you what to expect in smell, structure and temperament far better than any marketing copy.
- Yield estimates. Expressed 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few signs are worth knowing.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould disqualify a seed.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics make small seeds.
- Float test. Dropping seeds in water and discarding floaters is common but crude: fresh seeds often float until the shell takes on water.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- Keep them cool. A constant 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 dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either condition on its own; take out the container as rarely as possible.
Getting a Taproot
Each grower has a preferred 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 suffocate.
- Move them to a moist paper towel within a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot inside 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 as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stalls the seedling for good.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a middleman of uncertain stock appears in germination rates, not on the website.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should ship 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 carries lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder named on each product page.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in plain 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 requires the order number and, in most cases, a photo.
Before You Order: The Rules
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 hemp purposes, while germinating them remains illegal. In other places 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 ship to the United States, where importing of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Why did a seed fail to germinate?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are less common than grower error.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout well for two to three years and often much longer. Kept in a warm drawer, viability falls noticeably within a year.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, ridges or the crater at the base have no evidential 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 includes high-CBD lines with negligible THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
