Cannabis Seeds: Types and Storage

Any cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders across the industry. 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 properly.

One Seed, One Genetic Lottery Ticket

A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Mature seeds are typically brown, grey or tiger-striped, firm 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 energy to fuel 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 narrow that variation by stabilising a line over many generations, but some range is normal in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a taproot and the chance of a exceptional plant.

Regular, Feminized, Autoflowering: The Big Three

Almost every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.

• 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 contain ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, quicker and more forgiving of imperfect conditions, typically at the cost of yield and potency.
• Regular seeds give 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 mean identifying and removing males before they pollinate the females.

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 uncommon.

The Case for Feminized (and the Exceptions)

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 problem completely.

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 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 drops to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.

Autoflowers disregard the light schedule and bloom on a timer 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 continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a given footprint generally prefer 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 useful than the strain name.

• Yield estimates. Expressed 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 usually given as total time from seed. Check which convention the breeder uses.
• 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.
• Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing copy.

Telling Live Seeds From Dead Ones

Appearance is a rough guide to viability, not a test, but a few signs are reliable.

• Size. Bigger is not better; seed size varies by strain, and some top genetics produce small seeds.
• Surface. A faint waxy sheen is typical. Splits, dents or obvious mould disqualify a seed.
• Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
• Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell takes on water.
• Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.

Cool, Dark, Dry, Still

Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The threats are heat, light, moisture and change.

• Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
• Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as rarely as possible.
• Keep them dry. A sealed container with a desiccant packet prevents the humidity swings 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 dangerous unless the seeds are fully dried.

Cracking the Shell

Every grower has a favourite method, but the requirements are the same whichever you choose: moisture, warmth, darkness and oxygen.

1. Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can drown.
2. Move them to a moist paper towel inside a closed container, or directly into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
3. Leave them. Most seeds produce a taproot inside two to five days; some take a week or more.
4. Once the taproot is about a centimetre long, plant it root-down, just below the surface, and provide gentle light as soon as the seedling breaks the surface.

Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stalls the seedling for good.

Where the Seeds Come From Matters

Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of unknown stock shows up in germination rates, rather than on the website.

• Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
• Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out in plain language.
• 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.
• Pack options. Multiple pack sizes allow you to test 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 kept. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.

Delivery, Packaging and Replacements

Bud Weed Seeds ships 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 any seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds replaces it. The claim needs 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 differs widely by country. In many European countries seeds are sold legally as souvenirs or for agricultural purposes, while germinating them stays illegal. Elsewhere 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 ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.

Still Wondering?

Does Bud Weed Seeds stock CBD-only strains?

Yes. The catalogue includes high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.

Why did a seed fail to sprout?

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.

Are autoflowering seeds weaker?

Current 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 comparable.

Can I tell the sex of a seed by examining it?

No. Methods based on shape, ridges or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.

How long do cannabis seeds stay viable?

Stored cool, dark and dry, the majority of seeds sprout well for two to three years and often much longer. Left in a warm drawer, viability falls sharply within a year.
