Any cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com now carries 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.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store 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 reduce that variation by working a line over many generations, but some spread 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.
Three Seed Types, Three Different Grows
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they require identifying and culling males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are more compact, quicker and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description normally says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
For the bulk 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 discarded, and a single missed male can seed an entire room. Feminized seeds sidestep that issue completely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population frequently prefer the broader 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 difficult to defend.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay in vegetative growth as long as they receive long days and move to flowering when the light falls 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 ignore the light schedule and flower on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants remain 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 stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and most of it is more informative than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- Lineage. The parent strains tell 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. Confirm which convention the breeder follows.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a test, but a few signs are reliable.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Surface. A slight waxy sheen is normal. Splits, dimples or visible mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell takes on water.
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 still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; take out the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them cool. A constant 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 dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
The First Five Days
Every grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot inside two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stops the seedling permanently.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a serious 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 repackaged 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 shown on each product page.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be stated up front.
- Pack options. Flexible pack sizes let you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
Delivery, Packaging and Replacements
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 any seed fails to germinate within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The claim 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 differs widely by country. In many European jurisdictions seeds are traded legally as souvenirs 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 importing of cannabis seeds is not permitted. 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.
Quick Answers
Can I tell the sex of a seed by looking at it?
No. Methods 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, determines the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
Why did a seed fail to germinate?
The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than mistakes in the process.
Are autoflowering seeds weaker?
Current autos are far closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency from reputable breeders is comparable.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Kept in a warm drawer, viability falls noticeably within a year.
