Every cannabis plant starts 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 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 across the industry. 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.

What You Are Actually Buying

A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Viable seeds are usually brown, grey or mottled, 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 one-off 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 range is expected 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.

Three Seed Types, Three Different Grows

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

  • 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 mean identifying and culling males before they pollinate the females.
  • 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 carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of imperfect conditions, usually at the cost of yield and potency.

Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually 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 thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue entirely.

Regular seeds justify 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 hard to justify.

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 falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, shape the plant, then flip flowering when it fits the space.

Autoflowers ignore 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 run under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.

Beyond the Strain Name

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

  • Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
  • Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
  • Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.
  • THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Read them as a ceiling, not a promise.

A Quick Viability Check

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

  • Float test. Dropping seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell absorbs water.
  • Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
  • Surface. A slight waxy sheen is typical. Splits, dimples or visible mould disqualify a seed.
  • Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.

Cool, Dark, Dry, Still

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

  • Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that start premature germination or mould.
  • Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
  • Keep them still. Moving seeds between warm and cold repeatedly does more damage than either temperature on its own; take out the container as seldom as possible.
  • Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.

Cracking the Shell

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

  1. Place 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 moist paper towel within a closed container, or straight into a starter pot of light, damp medium. Keep the temperature comfortably warm.
  3. Wait. Most seeds show a taproot inside two to five days; some need a week or more.
  4. Once the taproot is about a centimetre long, plant it root-down, shallowly, and provide gentle light as soon as the seedling breaks the surface.

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

Vetting the Seller

Seeds are only as good as the source, and the difference between a reputable seed bank and a reseller of unknown stock shows up in germination rates, not on the website.

  • Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
  • 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 kept. Seeds left in a warm warehouse for a year drop viability long before they reach you.
  • Pack options. Multiple pack sizes allow you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
  • Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated in plain language.

From Checkout to Letterbox

Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no reference to the contents on the outside.

Every pack comes with a germination guarantee: if any seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The request 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 varies sharply by country. In many European jurisdictions seeds are sold legally as souvenirs or for hemp purposes, while germinating them remains 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 banned.

Bud Weed Seeds does not ship 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 taken as legal advice.

Still Wondering?

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 reveal preflowers, determines the sex.

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 similar.

How long do cannabis seeds last?

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

Does Bud Weed Seeds stock CBD-only strains?

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

Why did a seed fail to germinate?

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