Any cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts to light, how tall it grows, and the mix 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 currently lists 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 correctly.

What You Are Actually Buying

A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Viable seeds are usually brown, grey or mottled, 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 nutrients 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 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 taproot and the chance of a exceptional plant.

Regular, Feminized, Autoflowering: The Big Three

Nearly 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 contain ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
  • Feminized seeds are bred to produce female plants almost every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
  • Regular seeds produce male and female plants in about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, but 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 label usually says so. Regular autoflowering seeds exist but are rare.

When Regular Seeds Still Make Sense

For the majority of buyers the answer is feminized. If the goal 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 sidestep that issue entirely.

Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic spread of regular stock. And some traditional lines are simply available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.

Photoperiod Control vs. Autoflower Speed

Photoperiod plants stay in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That gives the grower control: veg for two weeks or two months, train the plant, then flip flowering when it fits the space.

Autoflowers ignore the light schedule and bloom on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays 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.

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.

  • Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder follows.
  • 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.
  • THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
  • Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
  • 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.

Telling Live Seeds From Dead Ones

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

  • Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
  • Surface. A slight waxy sheen is typical. Cracks, dimples or obvious mould disqualify a seed.
  • Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
  • Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
  • Float test. Dropping seeds in water and discarding floaters is popular but unreliable: healthy seeds often float until the shell absorbs water.

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 heat, light, moisture and change.

  • Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
  • Keep them dry. A airtight container with a desiccant packet stops the humidity changes that start premature germination or mould.
  • Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; open the container as seldom as possible.
  • Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.

The First Five Days

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

  1. Place the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can suffocate.
  2. Move them to a damp paper towel within a closed container, or straight into a small 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 take a week or more.
  4. 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.

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

Vetting the Seller

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

  • Pack options. Multiple pack sizes let you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
  • Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year drop viability before they reach you.
  • Breeder transparency. A good 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 shown on each product page.
  • Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be stated up front.

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 label.

Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started as described above, Bud Weed Seeds replaces it. The claim needs 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 differs sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for hemp purposes, while germinating them stays an offence. In other places both buying and growing are allowed 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 restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.

Still Wondering?

Does Bud Weed Seeds sell CBD-only strains?

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

How long do cannabis seeds last?

Stored cool, dark and dry, most seeds sprout well for two to three years and often much longer. Kept in a warm drawer, viability drops sharply within a year.

Are autoflowering seeds weaker?

Current autos are much closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency in good lines is similar.

Can I tell the sex of a seed by looking at 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 reveal preflowers, determines the sex.
