Every cannabis plant starts as a seed, and the seed settles 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 develop. Choosing well at this stage avoids months of lost 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 distinguishes a good seed from a poor one, and how to store and start them correctly.
What You Are Actually Buying
A cannabis seed is a small, hard embryo enclosed in a protective coat. Viable seeds are usually 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 one-off combination of its two parents, and that is why two seeds from the same pack can turn out noticeably unalike. Breeders narrow that variation by working a line over many generations, but some range is expected in any seed-grown crop. Clones are the only way to get identical 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 first decision a buyer makes.
- 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 wasted space of male plants.
- 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 less-than-ideal conditions, usually at the cost of yield and potency.
- Regular seeds produce male and female plants in about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they require identifying and culling males before they pollinate the females.
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 rare.
The Case for Feminized (and the Exceptions)
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 discarded, and a single overlooked 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 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 hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants remain in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That hands the grower control: veg for two weeks or two months, train the plant, then flip flowering when it fits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- 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.
- 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a promise.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing text.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Surface. A slight waxy sheen is typical. Splits, dents or obvious mould rule out a seed.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell takes on water.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Larger 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 collapse easily are non-viable.
Cool, Dark, Dry, Still
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as rarely as possible.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are fully dried.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
Getting a Taproot
Each grower has a preferred method, but the requirements are the same in all of them: 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 drown.
- Move them to a moist paper towel inside a closed container, or straight 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 need a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling emerges from the surface.
Handle 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
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, not on the website.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be spelled out up front.
- Breeder transparency. A trustworthy seller names 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.
- Pack options. Flexible pack sizes let you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no reference to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The request requires 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 sharply by country. In many European countries seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them remains an offence. In other places both buying and growing are permitted under licence or within personal limits, and in some countries possession of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Quick Answers
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 evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Why did a seed fail to sprout?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are less common than grower error.
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency in good lines is comparable.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
