Every cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how large 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 across the industry. This guide covers 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, 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 begin: 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, and that is why two seeds from the same pack can grow noticeably unalike. Breeders reduce that variation by stabilising a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a taproot and the chance of a standout 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 first decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of imperfect conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to yield female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
- 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, but they require 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 rare.
The Case for Feminized (and the Exceptions)
For the majority 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 discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population frequently prefer the broader genetic spread of regular stock. And some old-school 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 hands the grower the decision: veg for two weeks or two months, train the plant, then flip flowering when it suits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a given footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and much of it is more informative than the strain name.
- 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.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- 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.
- Yield estimates. Expressed 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.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a verdict, but a few indicators are reliable.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Surface. A slight waxy sheen is normal. Splits, dimples or obvious mould disqualify a seed.
- Float test. Placing seeds in water and discarding floaters is common but crude: fresh seeds often float until the shell takes on water.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- 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 trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either temperature on its own; take out the container as rarely as possible.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are bone dry.
Getting a Taproot
Each grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak 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 damp paper towel inside a closed container, or directly into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot within two to five days; some take 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 breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently 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 unknown stock appears in germination rates, rather than on the website.
- Pack options. Multiple pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out in plain language.
- Storage on their end. Ask how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of delivery when germinated as described above, Bud Weed Seeds sends a replacement for it. The claim needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European countries seeds are traded legally as souvenirs or for agricultural purposes, while germinating them stays an offence. In other places both buying and growing are permitted under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own country before ordering, and nothing on this page should be taken 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, as well as balanced and THC-dominant strains.
Why did a seed fail to sprout?
The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Genuinely dead seeds are rarer than mistakes in the process.
Are autoflowering seeds less potent?
Modern autos are much 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.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and often far longer. Left in a warm drawer, viability falls sharply within a year.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
