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 large it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids 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 properly.

What You Are Actually Buying

A cannabis seed is a small, hard embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, solid to the touch and a little glossy. Inside sits everything the plant needs to begin: 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, which is why two seeds from the same pack can turn out noticeably different. Breeders reduce that variation by stabilising 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 exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.

The First Decision: Seed Type

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

  • Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more forgiving of imperfect conditions, usually at the cost of yield and potency.
  • Regular seeds give male and female plants in roughly 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 seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.

Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.

The Case for Feminized (and the Exceptions)

For the majority of buyers the answer is feminized. If the aim is flower, every male plant is space, light and time spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.

Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population frequently prefer the broader genetic spread of regular stock. And some old-school lines are simply sold 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 receive long days and switch to flowering when the light drops to around twelve hours. That gives the grower control: veg for two weeks or two months, shape the plant, then trigger 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 downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, outdoor 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 useful than the strain name.

  • Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
  • THC and CBD ranges. Stated figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a promise.
  • Lineage. The parent strains tell you what to expect in aroma, 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 uses.

Telling Live Seeds From Dead Ones

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

  • Surface. A faint waxy sheen is normal. Splits, 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 hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.

Long-Term Seed Storage

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

  • Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky unless the seeds are bone dry.
  • Keep them dry. A airtight 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 damage than either condition 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

Every 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 up to a day to soften the shell. Any longer and they can drown.
  2. Move them to a damp paper towel within a closed container, or directly into a starter pot of light, damp medium. Keep the temperature comfortably warm.
  3. Leave them. Most seeds show 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, shallowly, and provide gentle light as soon as the seedling emerges from the surface.

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

Vetting the Seller

Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of uncertain stock appears in germination rates, rather than on the website.

  • Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
  • Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be spelled out up front.
  • Breeder transparency. A trustworthy seller lists 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.
  • Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.

Delivery, Packaging and Replacements

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 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 sends a replacement for it. The request needs the order number and, in most cases, a photo.

Before You Order: The Rules

The law on cannabis seeds is distinct from the law on cannabis itself, and it differs widely by country. In many European jurisdictions seeds are traded legally as souvenirs or for agricultural purposes, while germinating them stays illegal. Elsewhere 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 import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.

Still Wondering?

Why did a seed fail to sprout?

The most frequent causes are too long in water, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than mistakes in the process.

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

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

Does Bud Weed Seeds sell CBD-only strains?

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

Are autoflowering seeds weaker?

Current autos are far closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
