Every cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the mix 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 across the industry. 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 start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Viable seeds are usually brown, grey or mottled, 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 nutrients to fuel the first days of growth.
Genetically, each seed is a one-off 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 normal in any seed-grown crop. Clones are the only way to get exact copies; seeds trade that certainty for vigour, a taproot and the chance of a exceptional plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important 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 make their own seeds, but they mean identifying and removing males before they pollinate the females.
- Feminized seeds are bred to yield 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 carry ruderalis genetics that make 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.
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 bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem 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 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 remain 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 the decision: vegetate for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stressed 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 usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more informative than the strain name.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Read them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder follows.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Surface. A faint waxy sheen is normal. Splits, dents or visible mould rule out a seed.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- 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 popular but unreliable: healthy seeds often float until the shell takes on water.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; open the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that trigger premature germination or mould.
The First Five Days
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can drown.
- Move them to a moist paper towel within 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 within 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 once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one often stalls the seedling for good.
Vetting the Seller
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of unknown stock shows up in germination rates, not on the website.
- Breeder transparency. A good seller lists 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. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Pack options. Flexible pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to germinate within 14 days of arrival when germinated 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 varies widely by country. In many European countries seeds are traded legally as collectors’ items 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 ownership of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is not permitted. 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.
Still Wondering?
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout well for two to three years and often far longer. Kept in a warm drawer, viability falls noticeably within a year.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Are autoflowering seeds less potent?
Modern autos are much closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
