Every cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of lost effort later. The market has expanded 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.

One Seed, One Genetic Lottery Ticket

A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are typically brown, grey or mottled, solid to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of nutrients 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 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 exact copies; seeds trade that certainty for vigour, a 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 most important decision a buyer makes.

• Feminized seeds are bred to produce female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the lost space of male plants.
• Autoflowering seeds contain ruderalis genetics that cause the plant to flower 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.
• Regular seeds produce male and female plants in about 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 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.

Males: Asset or Liability?

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 discarded, and a single missed male can seed an entire room. Feminized seeds sidestep that issue completely.

Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population often prefer the broader genetic spread of regular stock. And some old-school lines are simply available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.

Photoperiod Control vs. Autoflower Speed

Photoperiod plants remain in vegetative growth as long as they get long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: veg 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, usually a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants remain 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 tend to succeed with autos; growers after 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 much of it is more informative than the strain name.

• 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 hint at growth habit (height, internode spacing, flowering time) more than at effect.
• 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.
• 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.

Signs of a Healthy Seed

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

• Surface. A faint waxy sheen is typical. Cracks, dents or obvious mould rule out a seed.
• Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
• Float test. Placing seeds in water and discarding floaters is common but unreliable: fresh seeds often float until the shell takes on water.
• Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are dead.

Long-Term Seed Storage

Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The enemies are warmth, light, moisture and change.

• Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
• Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are fully dried.
• Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
• Keep them still. Shifting seeds between warm and cold again and again does more harm than either condition on its own; take out the container as rarely as possible.

Getting a Taproot

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

1. Soak 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 damp paper towel inside a closed container, or directly into a starter pot of light, damp 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, shallowly, and provide gentle light as soon as the seedling emerges from the surface.

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

Where the Seeds Come From Matters

Genetics are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock appears in germination rates, not on the website.

• Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be spelled out in plain language.
• Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
• Pack options. Multiple pack sizes allow you to try a strain before committing; 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.

Delivery, Packaging and Replacements

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

Seeds come with a germination guarantee: if a seed fails to sprout 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 separate from the law on cannabis itself, and it varies widely by country. In many European countries seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them remains an offence. Elsewhere both buying and growing are permitted under licence or within personal limits, and in some countries possession of seeds alone is banned.

Bud Weed Seeds does not ship to the United States, where importing 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 CBD-dominant lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.

Why did a seed fail to sprout?

The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are less common than mistakes in the process.

How long do cannabis seeds stay viable?

Kept cool, dark and dry, most seeds sprout reliably for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply within a year.

Are autoflowering seeds weaker?

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 in good lines is comparable.
