A Grower’s Handbook to Cannabis Seeds

Every cannabis plant begins as a seed, and the seed decides 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 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 covers the main seed types, how to read a strain description, what distinguishes a good seed from a poor one, and how to store and germinate them properly.

One Seed, One Genetic Lottery Ticket

A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature 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 unique combination of its two parents, and that is why two seeds from the same pack can grow noticeably different. 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 strong taproot and the chance of a standout plant.

Three Seed Types, Three Different Grows

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 carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, quicker and more forgiving of imperfect conditions, typically at the cost of yield and potency.
• Regular seeds give male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, but they mean identifying and removing 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 remove the guesswork and the lost space of male plants.

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 uncommon.

When Regular Seeds Still Make Sense

For the bulk 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 problem entirely.

Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population often prefer the wider genetic variation of regular stock. And some traditional lines are simply available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.

Why Autos Behave Differently

Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light drops 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 clock set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is 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 stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers after maximum yield from a fixed footprint usually choose photoperiod stock.

Translating the Product Page

A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.

• 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.
• Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
• Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing copy.
• THC and CBD ranges. Quoted figures are from the breeder's own tests under ideal conditions. Treat them as a ceiling, not a guarantee.
• Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.

A Quick Viability Check

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

• Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
• Surface. A faint waxy sheen is typical. Splits, dimples or visible mould rule out a seed.
• Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
• Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell takes on water.

Cool, Dark, Dry, Still

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

• 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 degrades the embryo over time, so an opaque container is better than a clear one.
• 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 dry. A sealed container with a desiccant packet prevents the humidity changes that start premature germination or mould.

Cracking the Shell

Every grower has a favourite method, but the requirements are the same whichever you choose: 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 moist paper towel within a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
3. Wait. Most seeds produce a taproot within two to five days; some need a week or more.
4. Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and provide gentle light once the seedling breaks the surface.

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

Reputable Source, Reliable Sprouts

Seeds 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 sealed packs, not loose in a plain bag.
• Breeder transparency. A trustworthy seller names the breeder for every strain. Bud Weed Seeds stocks lines from Barney's Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder named on each product page.
• Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
• Pack options. Flexible 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 dispatched in plain packaging with no reference to the contents on the outside.

Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.

Before You Order: The Rules

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 souvenirs 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 possession 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 read as legal advice.

Quick Answers

How long do cannabis seeds last?

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

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

No. Claims 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, tells you the sex.

Are autoflowering seeds weaker?

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

Does Bud Weed Seeds sell CBD-only strains?

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

Why did a seed fail to germinate?

The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during handling. Genuinely dead seeds are less common than grower error.
