Cannabis Seeds: Storage, Germination and Types
Any cannabis plant begins 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 develop. Choosing well at this stage avoids months of wasted effort later. The market has expanded 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 distinguishes a good seed from a poor one, and how to store and start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually 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 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 different. Breeders reduce 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 trade that certainty for vigour, a taproot and the chance of a exceptional plant.
Regular, Feminized, Autoflowering: The Big Three
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- 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, but they require identifying and culling males before they pollinate the females.
- Autoflowering seeds contain ruderalis genetics that cause 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.
- Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.
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 rare.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, 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 issue completely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic variation of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
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 control: vegetate for two weeks or two months, shape the plant, then flip 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 grown under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers after maximum yield from a given footprint usually choose photoperiod stock.
Translating the Product Page
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- 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.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- 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.
- Yield estimates. Given 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.
- 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 follows.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked 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 good sign; seeds that collapse easily are non-viable.
- Surface. A faint waxy sheen is normal. Splits, dimples or visible mould rule out a seed.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored correctly 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 is better than a clear one.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that start premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature 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 harming it; the freezer is dangerous unless the seeds are bone dry.
The First Five Days
Every grower has a favourite method, but the essentials are the same whichever you choose: 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, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. 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, 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 breaks easily and a broken one often stalls the seedling for good.
Where the Seeds Come From Matters
Seeds 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.
- 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.
- Original packaging. Seeds should arrive in the breeder's original packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated in plain language.
- Storage on their end. Ask how stock is kept. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
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 label.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when started as described above, 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 sold legally as collectors' items or for hemp purposes, while germinating them stays an offence. 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 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 country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with negligible THC, marked as such on the product page, as well as 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. Genuinely dead seeds are less common than grower error.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds sprout reliably for two to three years and often much longer. Kept in a warm drawer, viability drops sharply within a year.
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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
Are autoflowering seeds less potent?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency in good lines is similar.
