Any cannabis plant begins 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 avoids months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. This guide explains 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 correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically 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 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 grow noticeably unalike. Breeders narrow that variation by working 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
Nearly every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred 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 more compact, faster and more tolerant of imperfect conditions, usually 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 lost space of male plants.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the bulk 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 discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic spread of regular stock. And some traditional lines are only 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 stay in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, shape the plant, then trigger 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 cycle from seed to harvest is much shorter, the plants remain small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a given footprint usually choose photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more informative than the strain name.
- Yield estimates. Expressed 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.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing text.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a guarantee.
- 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.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few signs are worth knowing.
- Float test. Dropping seeds in water and discarding floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Bigger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Surface. A slight waxy sheen is normal. Cracks, dimples or obvious mould disqualify a seed.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
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 warmth, light, moisture and change.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; take out the container as rarely 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 swings that start premature germination or mould.
- 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 bone dry.
The First Five Days
Every grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can drown.
- Move them to a damp paper towel within a closed container, or directly into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds produce a taproot within two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stops the seedling for good.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a reseller of uncertain stock appears in germination rates, rather than on the website.
- Storage on their end. Ask how stock is kept. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- 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 shown on each product page.
What Happens After Checkout
Bud Weed Seeds ships 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 sprout within 14 days of arrival when started as described above, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies widely by country. In many European countries seeds are sold legally as collectors’ items or for agricultural 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 ownership 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 responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
Are autoflowering seeds less potent?
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 similar.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, most seeds germinate well for two to three years and frequently much longer. Left in a warm drawer, viability falls sharply within a year.
