Every cannabis plant starts as a seed, and the seed settles 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 develop. 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 around the world. This guide explains 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.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, 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 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 grow noticeably different. Breeders reduce that variation by stabilising a line over many generations, but some range is normal in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Almost every seed on sale falls into one of three categories, and the choice between them is the most important 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.
- Regular seeds produce 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 require identifying and culling males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, quicker and more tolerant of imperfect conditions, usually at the cost of yield and potency.
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 uncommon.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is space, light and time spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds earn 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 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.
Why Autos Behave Differently
Photoperiod plants stay in vegetative growth as long as they get 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 flip flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is 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 often succeed with autos; growers after maximum yield from a fixed footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more useful than the strain name.
- 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.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing text.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal conditions. Read them as a ceiling, not a promise.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent 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 verdict, but a few signs are worth knowing.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
- Surface. A faint waxy sheen is normal. Splits, dents or visible mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are dead.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept 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 repeatedly does more harm than either temperature on its own; open the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- 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 slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
The First Five Days
Every grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Soak 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 moist paper towel inside a closed container, or straight into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot inside two to five days; some take a week or more.
- 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 broken one often stops the seedling for good.
Where the Seeds Come From Matters
Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of uncertain stock shows up in germination rates, rather than on the website.
- Breeder transparency. A good seller lists 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 named on each product page.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated up front.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in plain packaging with no mention to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of arrival when started by the recommended method, 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 distinct from the law on cannabis itself, and it differs widely by country. In many European countries seeds are traded legally as souvenirs or for agricultural purposes, while germinating them remains illegal. Elsewhere 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 send orders to the United States, where importing of cannabis seeds is not permitted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and often far longer. Kept in a warm drawer, viability falls sharply within a year.
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 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, as well as balanced and THC-dominant strains.
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 damage to the taproot during handling. Genuinely dead seeds are less common than grower error.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
