Every cannabis plant starts as a seed, and the seed decides more than most people 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 lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 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 properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard embryo wrapped in a protective coat. Viable seeds are typically 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 fuel 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 turn out noticeably different. 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 exceptional plant.
Regular, Feminized, Autoflowering: The Big Three
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 very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
- Regular seeds produce male and female plants in roughly equal numbers. They are favoured 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 and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the bulk of buyers the answer is feminized. If the goal is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population often prefer the wider genetic spread of regular stock. And some traditional lines are simply 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 drops to around twelve hours. That hands the grower control: veg for two weeks or two months, shape 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 much 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 chasing maximum yield from a given footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and much 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 follows.
- Lineage. The parent strains tell you what to expect in smell, 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. Read them as a ceiling, not a promise.
- 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.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
A Quick Viability Check
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell takes on water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as seldom as possible.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
Getting a Taproot
Every grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show a taproot within 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 once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling for good.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a middleman of unknown stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- 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 named on each product page.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated up front.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds replaces it. The claim needs 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 jurisdictions seeds are traded legally as souvenirs or for agricultural purposes, while germinating them stays illegal. Elsewhere 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 import of cannabis seeds is not permitted. 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 last?
Kept 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 drops sharply within a year.
Why did a seed fail to sprout?
The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during transplanting. Truly dead seeds are rarer than mistakes in the process.
Are autoflowering seeds weaker?
Current autos are far 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 comparable.
Does Bud Weed Seeds stock 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.
