Every cannabis plant starts 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 mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of lost effort later. The market has expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders across the industry. 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 tiny, hard embryo wrapped in a protective coat. Mature seeds are typically brown, grey or mottled, solid to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store 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 narrow 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 identical copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale belongs to 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 make their own seeds, though they require identifying and removing males before they pollinate the females.
- 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 less-than-ideal conditions, usually at the cost of yield and potency.
- 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 wasted space of male plants.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the majority of buyers the answer is feminized. If the goal is flower, every male plant is space, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population often prefer the broader genetic variation of regular stock. And some traditional lines are simply 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 stay 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: vegetate for two weeks or two months, train the plant, then flip flowering when it fits the space.
Autoflowers ignore the light schedule and bloom 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 long 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 tend to succeed with autos; growers chasing maximum yield from a given 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 useful than the strain name.
- Yield estimates. Expressed 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.
- 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 temperament far better than any marketing text.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under ideal 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.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a test, but a few indicators are worth knowing.
- Float test. Placing seeds in water and discarding floaters is popular but unreliable: healthy seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- Surface. A slight waxy sheen is normal. Cracks, dents or obvious mould disqualify a seed.
- Size. Larger is not better; 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 crush easily are dead.
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 threats are heat, light, moisture and fluctuation.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; open the container as rarely as possible.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky unless the seeds are bone dry.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
Cracking the Shell
Every grower has a preferred method, but the requirements are the same in all of them: 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 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 comfortably warm.
- Wait. Most seeds produce a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one often stalls the seedling for good.
Reputable Source, Reliable Sprouts
Seeds are only as good as the supplier, and the difference between a serious seed bank and a middleman of uncertain 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 long before they reach you.
- Breeder transparency. A trustworthy seller lists the breeder for every strain. Bud Weed Seeds carries 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.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out up front.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference 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 needs the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is separate from the law on cannabis itself, and it differs widely by country. In many European jurisdictions seeds are sold legally as souvenirs or for agricultural purposes, while germinating them stays illegal. Elsewhere both buying and growing are permitted under licence or within personal limits, and in some countries ownership 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 country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
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 in good lines is similar.
Can I tell the sex of a seed by examining 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.
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 injury to the taproot during handling. Genuinely dead seeds are less common than mistakes in the process.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply within a year.
