A Grower’s Handbook to Cannabis Seeds

Every cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how large 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 grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide explains the main seed types, how to read a strain description, what distinguishes 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 tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or mottled, solid to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of nutrients to power 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 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 identical copies; seeds trade that certainty for vigour, a 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.

• Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster 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 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 produce 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 description normally 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 goal is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.

Regular seeds justify their place in three situations. Breeders need males to provide 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 simply sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.

Photoperiod Control vs. Autoflower Speed

Photoperiod plants stay 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 the decision: vegetate for two weeks or two months, train the plant, then trigger flowering when it suits the space.

Autoflowers disregard the light schedule and flower on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a fixed footprint generally choose 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.

• 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.
• Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing text.
• 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 uses.
• Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.

A Quick Viability Check

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

• Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
• Surface. A slight waxy sheen is typical. Splits, dents or visible mould rule out a seed.
• Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
• Shell. A firm 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 generally mature. Pale green or white seeds were harvested too early and rarely sprout.

Cool, Dark, Dry, Still

Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The enemies 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 dangerous unless the seeds are bone dry.
• Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
• Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that start premature germination or mould.
• Keep them still. Moving seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as seldom as possible.

The First Five Days

Every grower has a preferred method, but the essentials are the same whichever you choose: 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 damp paper towel within a closed container, or straight into a starter pot of light, moist medium. Keep the temperature comfortably warm.
3. Leave them. Most seeds produce 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, 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 often stalls the seedling for good.

Where the Seeds Come From Matters

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

• Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
• Breeder transparency. A good 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 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.
• Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.

From Checkout to Letterbox

Bud Weed Seeds ships 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 a seed fails to sprout within 14 days of delivery when started by the recommended method, Bud Weed Seeds sends a replacement for it. The request requires 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 varies sharply by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains an offence. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.

Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. It is the buyer’s duty to check 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 last?

Kept cool, dark and dry, the majority of seeds germinate well for two to three years and frequently much longer. Kept 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 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 stock CBD-only strains?

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

Are autoflowering seeds less potent?

Modern autos are much closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency in good lines is similar.
