Every cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 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 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 slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of nutrients to power 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 grow noticeably unalike. Breeders narrow that variation by stabilising a line over many generations, but some spread is expected 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
Nearly every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they require 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.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
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 goal is flower, every male plant is room, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds earn their place in three 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.
Light-Driven or Clock-Driven?
Photoperiod plants remain in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: vegetate for two weeks or two months, shape the plant, then flip flowering when it suits 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 grown under long light from start to finish. The downside 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 generally prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and much 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 often given as total time from seed. Check which convention the breeder follows.
- 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.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Surface. A slight waxy sheen is typical. Cracks, dents or obvious mould rule out a seed.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky 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.
Cracking the Shell
Every grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Soak 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 directly into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds produce a taproot inside two to five days; some take 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 breaks easily and a broken one frequently stops the seedling permanently.
Where the Seeds Come From Matters
Seeds 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, rather than on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out in plain language.
- Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the outside.
Seeds come with a germination guarantee: if a seed fails to germinate 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 differs sharply by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays 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 send orders to the United States, where import of cannabis seeds is not permitted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, ridges or the scar 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 stock CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply within a year.
Why did a seed fail to germinate?
The commonest 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 rarer than grower error.
