Any cannabis plant begins 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 balance of cannabinoids and terpenes it can produce. Choosing well at this stage avoids 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 germinate 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, firm 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 nutrients to fuel 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 reduce that variation by working a line over many generations, but some range is expected in any seed-grown crop. Clones are the only way to get identical copies; seeds trade 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 belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Regular seeds produce male and female plants in about 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 lost 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, faster and more tolerant of imperfect 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 description normally says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population frequently prefer the wider genetic spread of regular stock. And some old-school lines are only 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 drops to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a clock set by genetics, typically 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 long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a fixed footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more informative 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. Confirm which convention the breeder uses.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- 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 growth habit far better than any marketing copy.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Size. Larger is not better; seed size varies by strain, and some top genetics make small seeds.
- Surface. A faint waxy sheen is normal. Cracks, dents or visible mould disqualify a seed.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are dead.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are warmth, light, moisture and fluctuation.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either condition on its own; open the container as seldom as possible.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that start 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 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 up to a day to soften the shell. Longer and they can drown.
- Move them to a damp paper towel within a closed container, or directly into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show 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, just below the surface, and give gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stalls the seedling permanently.
Reputable Source, Reliable Sprouts
Seeds are only as good as the source, and the difference between a serious seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A good 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.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out in plain language.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
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 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 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 varies sharply by country. In many European jurisdictions seeds are traded legally as souvenirs or for hemp 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 possession of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is restricted. 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.
Still Wondering?
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and often far longer. Kept in a warm drawer, viability falls noticeably within a year.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Why did a seed fail to germinate?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are rarer than grower error.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
