Every cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how large it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com currently lists 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 embryo wrapped in a protective coat. Mature 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 reserve of nutrients 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 turn out noticeably different. Breeders narrow 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 identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
The First Decision: Seed Type
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 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 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 carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, faster 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 normally says so. Regular autoflowering seeds exist but are rare.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the goal is flower, every male plant is space, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue 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 broader genetic spread of regular stock. And some traditional 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 receive 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, train the plant, then flip flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder uses.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal conditions. Treat them as a ceiling, not a promise.
- Lineage. The parent strains show you what to expect in smell, structure and temperament far better than any marketing copy.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few indicators are reliable.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: healthy seeds often float until the shell takes on water.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould rule out a seed.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
- 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 light-proof container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either condition on its own; open the container as rarely as possible.
Cracking the Shell
Every grower has a favourite method, but the requirements are the same whichever you choose: 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 suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a small pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show 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, shallowly, and provide gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged 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 reseller of unknown stock shows up in germination rates, not on the website.
- 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 stocks lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder shown on each product page.
- Pack options. Multiple pack sizes allow you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year lose viability 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.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the outside.
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 replaces it. The request requires the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are traded legally as souvenirs or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
Are autoflowering seeds less potent?
Current autos are far closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
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 damage to the taproot during transplanting. Truly dead seeds are rarer than mistakes in the process.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently far longer. Kept in a warm drawer, viability drops noticeably within a year.
