Every cannabis plant starts 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 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 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 tiny, hard embryo wrapped in a protective coat. Viable 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 energy 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 grow noticeably unalike. Breeders reduce that variation by working a line over many generations, but some spread is normal 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 exceptional plant.

Three Seed Types, Three Different Grows

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

• Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
• Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they require identifying and culling males before they pollinate the females.
• Feminized seeds are bred to yield 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 label normally says so. Regular autoflowering seeds exist but are uncommon.

When Regular Seeds Still Make Sense

For the majority of buyers the answer is feminized. If the aim 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 entirely.

Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population often prefer the wider genetic spread of regular stock. And some traditional 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 switch to flowering when the light falls to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, train the plant, then flip flowering when it fits the space.

Autoflowers ignore the light schedule and flower on a timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants remain small, and they can be run under long 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 tend to do well with autos; growers chasing maximum yield from a given footprint usually prefer 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.

• Yield estimates. Given 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.
• Sativa, indica or hybrid. These days 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.
• Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
• THC and CBD ranges. Stated figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.

A Quick Viability Check

Appearance is a loose guide to viability, not a test, but a few indicators are reliable.

• Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are dead.
• Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
• Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
• Surface. A slight waxy sheen is typical. Splits, dents or visible mould rule out a seed.

Long-Term Seed Storage

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

• Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
• Keep them still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as seldom as possible.
• 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 bone dry.
• Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.

Cracking the Shell

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

1. Soak the seeds in room-temperature water for up to a day to soften the shell. Longer and they can drown.
2. Move them to a damp paper towel within a closed container, or straight into a starter pot of light, moist 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 need a week or more.
4. Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling emerges from the surface.

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

Vetting the Seller

Seeds are only as good as the supplier, 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 stored. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
• Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out up front.
• 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 test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.

Delivery, Packaging and Replacements

Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention 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 as described above, Bud Weed Seeds replaces it. The request needs 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 jurisdictions seeds are traded legally as souvenirs 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 ownership of seeds alone is prohibited.

Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is not permitted. 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.

Quick Answers

Does Bud Weed Seeds stock CBD-only strains?

Yes. The catalogue has 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 injury to the taproot during transplanting. Genuinely dead seeds are less common than mistakes in the process.

Can I tell the sex of a seed by looking at it?

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

How long do cannabis seeds last?

Kept cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently much longer. Kept in a warm drawer, viability drops noticeably within a year.
