Any cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 400 strains from breeders around the world. This guide covers 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 correctly.

Anatomy of a Seed

A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Viable seeds are typically 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 store of energy to fuel 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 turn out noticeably different. 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 exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.

Three Seed Types, Three Different Grows

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 about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they mean identifying and culling males before they pollinate the females.
• Autoflowering seeds contain ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
• 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 lost space of male plants.

Feminized and autoflowering are not opposites: 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 bulk 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 discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue entirely.

Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population often prefer the wider genetic spread of regular stock. And some old-school 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 remain in vegetative growth as long as they get long days and move to flowering when the light drops to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, shape the plant, then flip flowering when it suits the space.

Autoflowers ignore the light schedule and flower on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a given footprint usually choose photoperiod stock.

Numbers on the Pack, Explained

A seed listing contains a lot of information into a few lines, and most of it is more useful than the strain name.

• 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 tell you what to expect in smell, structure and temperament far better than any marketing text.
• Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder follows.
• 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.

A Quick Viability Check

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

• Surface. A slight waxy sheen is typical. Splits, dents or visible mould disqualify a seed.
• Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
• Size. Larger is not better; seed size varies by strain, and some top genetics make small seeds.
• Float test. Placing seeds in water and rejecting floaters is popular but unreliable: healthy seeds often float until the shell takes on water.
• Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are dead.

Cool, Dark, Dry, Still

Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and fluctuation.

• Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
• Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
• Keep them still. Moving seeds between warm and cold again and again does more damage than either temperature on its own; take out the container as seldom as possible.
• Keep them dry. A airtight container with a desiccant packet stops the humidity swings that trigger premature germination or mould.

The First Five Days

Each grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and air.

1. Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
2. Move them to a damp paper towel within a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
3. Leave them. Most seeds produce a taproot within two to five days; some take a week or more.
4. Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling breaks the surface.

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

Where the Seeds Come From Matters

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, not on the website.

• 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.
• Breeder transparency. A trustworthy seller names 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.
• Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
• Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.

From Checkout to Letterbox

Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the label.

Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The request requires the order number and, in most cases, a photo.

Before You Order: The Rules

The law on cannabis seeds is separate from the law on cannabis itself, and it varies widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are permitted 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 importing of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.

Still Wondering?

How long do cannabis seeds stay viable?

Kept cool, dark and dry, the majority of seeds sprout well for two to three years and often far longer. Kept in a warm drawer, viability falls noticeably within a year.

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

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

Does Bud Weed Seeds sell CBD-only strains?

Yes. The catalogue has CBD-dominant lines with minimal THC, marked as such on the product page, as well as 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 transplanting. Truly dead seeds are less common than grower error.
