Any cannabis plant begins 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 produce. Choosing well at this stage saves months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 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 start them properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Viable seeds are usually brown, grey or tiger-striped, solid 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 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 range 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
Almost 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 favoured 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.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more forgiving 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 label usually 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 weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that problem completely.
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 often 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 difficult to defend.
Why Autos Behave Differently
Photoperiod plants stay 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 control: vegetate for two weeks or two months, train the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and flower on a timer 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 grown under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a fixed footprint usually choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- 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.
- 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 measured from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
A Quick Viability Check
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Surface. A slight waxy sheen is typical. Cracks, dimples or obvious mould disqualify a seed.
- Float test. Dropping seeds in water and rejecting floaters is common but crude: healthy 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.
- Size. Bigger is not better; seed size varies by strain, and some top genetics make 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 threats are warmth, light, moisture and change.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- 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 fully dried.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; take out the container as rarely as possible.
The First Five Days
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Place 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 inside a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce 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, just below the surface, and provide gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling for good.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock shows up in germination rates, rather than on the website.
- Storage on their end. Check how stock is stored. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- 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.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out up front.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Pack options. Multiple pack sizes let you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of arrival when started as described above, Bud Weed Seeds replaces it. The claim 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 differs widely by country. In many European jurisdictions seeds are sold legally as souvenirs or for agricultural purposes, while germinating them remains an offence. In other places 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 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.
Questions Growers Ask
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Why did a seed fail to germinate?
The commonest causes are too long in water, cold, a medium that is too wet or too dry, and injury to the taproot during transplanting. Genuinely dead seeds are less common than grower error.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Are autoflowering seeds less potent?
Current autos are far closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency from reputable breeders is comparable.
