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 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 currently lists 400 strains from breeders around the world. This guide explains 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 properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are usually brown, grey or tiger-striped, firm to the touch and slightly 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, which 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 range is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
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 about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they mean identifying and culling 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 eliminate the guesswork and the wasted space of male plants.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more tolerant of imperfect conditions, usually 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.
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 thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds earn their place in a few situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic variation 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 get long days and move to flowering when the light falls to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be run under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint generally choose photoperiod stock.
Translating the Product Page
A seed listing contains a lot of information into a few lines, and much of it is more useful than the strain name.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point 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.
- 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.
- Lineage. The parent strains show you what to expect in smell, structure and temperament far better than any marketing copy.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few signs are worth knowing.
- Surface. A slight waxy sheen is typical. Cracks, dimples or visible mould disqualify a seed.
- Shell. A firm shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are dead.
- Float test. Dropping seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell takes on water.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and seldom sprout.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them cool. A steady 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 dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings 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; open the container as seldom as possible.
The First Five Days
Every grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel within a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Leave them. Most seeds produce a taproot inside 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 provide gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stops the seedling permanently.
Where the Seeds Come From Matters
Genetics 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, rather than on the website.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be spelled out in plain language.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Pack options. Multiple pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started as described above, Bud Weed Seeds replaces 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 varies widely by country. In many European jurisdictions seeds are sold legally as souvenirs or for hemp purposes, while germinating them remains an offence. In other places both buying and growing are allowed under licence or within personal limits, and in some countries possession of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where importing 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.
Quick Answers
Why did a seed fail to sprout?
The commonest causes are too long in water, cold, a medium that is too wet or too dry, and damage to the taproot during transplanting. Genuinely dead seeds are less common than grower error.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and often far longer. Left in a warm drawer, viability falls noticeably within a year.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has high-CBD lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
