Any cannabis plant starts as a seed, and the seed decides 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 develop. Choosing well at this stage saves months of lost 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 distinguishes 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 tiger-striped, 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 one-off combination of its two parents, and that is why two seeds from the same pack can grow noticeably unalike. Breeders reduce that variation by working 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.
The First Decision: Seed Type
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to make their own seeds, but they require identifying and removing males before they pollinate the females.
- Feminized seeds are bred to produce female plants very nearly every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.
- Autoflowering seeds contain 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, usually at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are uncommon.
When Regular Seeds Still Make Sense
For the majority 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 justify their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Why Autos Behave Differently
Photoperiod plants remain 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 control: vegetate for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and bloom 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 run under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint generally choose 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.
- 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.
- 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 follows.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.
- 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.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few indicators are reliable.
- Shell. A firm shell that does not crack 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 visible mould disqualify a seed.
- Float test. Dropping seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Size. Bigger 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 rarely sprout.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either condition on its own; take out the container as seldom as possible.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
Cracking the Shell
Every grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- 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 damp paper towel within a closed container, or straight into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds produce a taproot within two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling permanently.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of uncertain stock shows up in germination rates, not on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out up front.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Pack options. Multiple pack sizes let you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- 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.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
Delivery, Packaging and Replacements
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 label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of arrival when germinated as described above, Bud Weed Seeds sends a replacement for it. The request requires the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are traded legally as souvenirs or for hemp purposes, while germinating them remains an offence. Elsewhere both buying and growing are allowed 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 import of cannabis seeds is restricted. It is the buyer’s responsibility to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably 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. Claims based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
Are autoflowering seeds weaker?
Modern 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 similar.
