Every cannabis plant begins 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 wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 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 germinate them correctly.
Anatomy of a Seed
A cannabis seed is a small, 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 start: a root tip, two cotyledon leaves and a store of nutrients to power 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 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 identical copies; seeds exchange that certainty for vigour, a taproot and the chance of a exceptional plant.
Three Seed Types, Three Different Grows
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 very nearly every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the lost space of male plants.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, faster and more tolerant of less-than-ideal conditions, usually 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 require 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 usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the majority 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 thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue completely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to select a keeper 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 remain in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That hands the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint generally prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing copy.
- 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.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a guarantee.
- 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.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that collapse easily are dead.
- Surface. A slight waxy sheen is normal. Cracks, dents or visible mould rule out a seed.
- 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 top genetics produce small seeds.
- Float test. Placing seeds in water and discarding floaters is popular but unreliable: healthy seeds often float until the shell takes on water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either temperature on its own; open the container as seldom as possible.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous 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.
Getting a Taproot
Each grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can drown.
- Move them to a moist paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show a taproot inside two to five days; some need a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once 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.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a reputable seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Pack options. Flexible pack sizes allow you to test a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out in plain language.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the outside.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of delivery when started as described above, Bud Weed Seeds replaces it. The claim 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 varies widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains 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 country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently far longer. Left in a warm drawer, viability drops sharply within a year.
Does Bud Weed Seeds sell 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.
Can I tell the sex of a seed by looking at 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 reveal preflowers, tells you the sex.
Are autoflowering seeds less potent?
Modern autos are far 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 comparable.
