Every cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of wasted effort later. The market has expanded 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 separates a good seed from a poor one, and how to store and start them properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store of nutrients to fuel the first days of growth.
Genetically, each seed is a unique 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 range is normal 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.
Three Seed Types, Three Different Grows
Almost every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Feminized seeds are bred to produce female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the lost space of male plants.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom 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.
- Regular seeds give male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though 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 label usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
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 thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population often prefer the wider genetic spread 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 hard to justify.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay in vegetative growth as long as they get long days and switch to flowering when the light drops to around twelve hours. That hands the grower control: vegetate for two weeks or two months, train the plant, then trigger flowering when it suits 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 stay small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers after maximum yield from a given footprint generally 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 useful than the strain name.
- 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.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing text.
- Yield estimates. Given 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few indicators are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Float test. Placing seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell absorbs water.
- Surface. A faint waxy sheen is typical. Splits, dents or obvious mould rule out a seed.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- 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 dry. A sealed container with a desiccant packet stops 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.
The First Five Days
Each grower has a preferred method, but the essentials 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 suffocate.
- Move them to a moist paper towel inside a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. 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 give gentle light as soon as the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stalls the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the source, and the difference between a serious seed bank and a reseller of unknown stock shows up in germination rates, not on the website.
- Breeder transparency. A good 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.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be spelled out up front.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no mention to the contents on the outside.
Every pack comes 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 request requires the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are sold legally as souvenirs or for agricultural purposes, while germinating them remains 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 jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout well for two to three years and frequently much longer. Left in a warm drawer, viability falls sharply within a year.
Are autoflowering seeds weaker?
Modern autos are much closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency from reputable breeders is similar.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Why did a seed fail to sprout?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
