Any cannabis plant starts as a seed, and the seed decides 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 produce. Choosing well at this stage avoids months of wasted 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 separates a good seed from a poor one, and how to store and germinate them correctly.
What You Are Actually Buying
A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Mature seeds are typically brown, grey or tiger-striped, solid 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 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 narrow that variation by stabilising a line over many generations, but some spread is normal in any seed-grown crop. Clones are the only way to get identical copies; seeds trade that certainty for vigour, a strong taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
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 remove 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 tolerant of imperfect conditions, typically at the cost of yield and potency.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they mean identifying and removing males before they pollinate the females.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
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 thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn 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 old-school lines are simply available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: vegetate for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers ignore 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 shorter, the plants remain small, and they can be run under long light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, outdoor 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 uses.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under controlled conditions. Read them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a verdict, but a few indicators are worth knowing.
- Size. Bigger 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 non-viable.
- Surface. A faint waxy sheen is normal. Splits, dimples 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 seldom sprout.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; take out the container as rarely as possible.
The First Five Days
Every grower has a favourite method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for no more than a day to soften the shell. Any 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.
- Wait. Most seeds produce 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 give gentle light as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one often stops the seedling permanently.
Where the Seeds Come From Matters
Seeds 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, not on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be spelled out up front.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Breeder transparency. A trustworthy 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 shown on each product page.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in plain packaging with no mention 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 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 widely by country. In many European countries seeds are traded legally as collectors’ items or for hemp purposes, while germinating them stays illegal. In other places 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 ship to the United States, where importing of cannabis seeds is restricted. It is the buyer’s duty to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Why did a seed fail to sprout?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during transplanting. Truly dead seeds are less common than mistakes in the process.
Are autoflowering seeds less potent?
Current autos are far closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency in good lines 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.
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 much longer. Kept in a warm drawer, viability falls sharply within a year.
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 evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
