Every cannabis plant begins 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 mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of lost effort later. The market has grown enormously, and https://budweedseeds.com now carries 400 strains from breeders around the world. 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.
What You Are Actually Buying
A cannabis seed is a small, hard embryo wrapped in a protective coat. Viable seeds are typically brown, grey or mottled, solid to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve of nutrients to power 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 exceptional plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal conditions, usually 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 make their own seeds, though they require identifying and culling males before they pollinate the females.
- Feminized seeds are bred to produce 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.
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 uncommon.
When Regular Seeds Still Make Sense
For the bulk 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 discarded, and a single missed male can seed an entire room. Feminized seeds avoid that issue entirely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population frequently prefer the broader genetic variation of regular stock. And some old-school lines are only available 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 move to flowering when the light falls to around twelve hours. That gives 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, 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 stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a given footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
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. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder uses.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing copy.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few indicators are worth knowing.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- 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.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either temperature on its own; take out the container as rarely as possible.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
Getting a Taproot
Every grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a starter pot of light, moist 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 give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stalls the seedling for good.
Vetting the Seller
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.
- Pack options. Multiple pack sizes let you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A trustworthy 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 named on each product page.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
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 outside.
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 sends a replacement for it. The request 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 differs widely by country. In many European countries seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. Elsewhere both buying and growing are permitted 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 check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently far longer. Left in a warm drawer, viability drops noticeably within a year.
Can I tell the sex of a seed by looking at 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.
Does Bud Weed Seeds sell 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.
Are autoflowering seeds weaker?
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.
