Cannabis Seeds Demystified

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 produce. Choosing well at this stage avoids months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 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 start them properly.

What You Are Actually Buying

A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically 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 energy to power 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 grow noticeably unalike. Breeders narrow 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 trade that certainty for vigour, a taproot and the chance of a standout plant.

Regular, Feminized, Autoflowering: The Big Three

Almost every seed on sale belongs to one of three categories, and the choice between them is the most important 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 less-than-ideal conditions, typically at the cost of yield and potency.
  • Regular seeds give male and female plants in about equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they mean identifying and removing 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 usually 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 room, 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 a few situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population frequently prefer the broader genetic variation of regular stock. And some old-school lines are only sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.

Light-Driven or Clock-Driven?

Photoperiod plants remain in vegetative growth as long as they receive 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, train the plant, then flip flowering when it fits the space.

Autoflowers disregard the light schedule and bloom on a clock set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a given footprint usually prefer photoperiod stock.

Numbers on the Pack, Explained

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

  • THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal conditions. Treat them as a ceiling, not a guarantee.
  • Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
  • Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder follows.
  • Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.

A Quick Viability Check

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

  • Surface. A faint waxy sheen is normal. Splits, dimples or visible mould rule out a seed.
  • Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
  • Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
  • Float test. Dropping seeds in water and discarding floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.

Cool, Dark, Dry, Still

Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and fluctuation.

  • Keep them cool. A steady 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 dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
  • Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as seldom as possible.
  • Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.

The First Five Days

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

  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 moist paper towel within a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
  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, shallowly, and provide gentle light as soon as the seedling emerges from the surface.

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

Reputable Source, Reliable Sprouts

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

  • Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
  • Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be stated up front.
  • Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
  • Pack options. Multiple pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.

What Happens After Checkout

Bud Weed Seeds ships 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 sprout 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 varies widely by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays illegal. In other places 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 duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.

Still Wondering?

How long do cannabis seeds stay viable?

Kept cool, dark and dry, the majority of seeds germinate well for two to three years and often far longer. Left in a warm drawer, viability falls noticeably within a year.

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

No. Methods based on shape, ridges or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.

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, as well as balanced and THC-dominant strains.

Are autoflowering seeds weaker?

Modern autos are much 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.
