A Grower’s Handbook to Cannabis Seeds

Every cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. 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.

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 start: a root tip, two cotyledon leaves and a reserve of energy to fuel the first days of growth.

Genetically, each seed is a one-off combination of its two parents, which is why two seeds from the same pack can turn out noticeably unalike. Breeders narrow that variation by working 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 trade that certainty for vigour, a strong taproot and the chance of a standout plant.

The First Decision: Seed Type

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

• 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 lost space of male plants.
• Autoflowering seeds contain ruderalis genetics that cause the plant to flower 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, but they mean identifying and culling males before they pollinate the females.

Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description normally 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 aim 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 sidestep that problem completely.

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 wider 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 hard to justify.

Why Autos Behave Differently

Photoperiod plants stay in vegetative growth as long as they get long days and switch to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, train the plant, then trigger flowering when it suits 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 remain small, and they can be run under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a given footprint generally choose photoperiod stock.

Beyond the Strain Name

A seed listing contains a lot of information into a few lines, and most 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. Use them to compare strains from the same breeder, not across breeders.
• Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
• THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
• 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 follows.
• Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.

Telling Live Seeds From Dead Ones

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

• Float test. Placing seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell takes on water.
• Surface. A faint waxy sheen is normal. Cracks, dimples or visible mould disqualify a seed.
• Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
• Colour. Brown, tan, grey or striped seeds are usually 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.

Cool, Dark, Dry, Still

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

• Keep them still. Shifting seeds between warm and cold again and again does more harm than either condition on its own; open the container as rarely as possible.
• Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming 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.
• Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.

The First Five Days

Each grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.

1. Soak the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can drown.
2. Move them to a damp paper towel inside a closed container, or directly into a starter pot of light, moist 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 reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light as soon as the seedling emerges from the surface.

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

Vetting the Seller

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

• Pack options. Multiple pack sizes allow you to test a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
• 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 shown on each product page.
• Storage on their end. Ask how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
• Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
• Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be stated up front.

Delivery, Packaging and Replacements

Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the outside.

Seeds come with a germination guarantee: if any 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.

Seeds, Plants and the Law

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 sold legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. Elsewhere both buying and growing are permitted 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 check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.

Questions Growers Ask

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 injury to the taproot during transplanting. Genuinely dead seeds are less common than grower error.

How long do cannabis seeds last?

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

Can I tell the sex of a seed by looking at it?

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

Are autoflowering seeds weaker?

Current autos are much 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.

Does Bud Weed Seeds sell CBD-only strains?

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