Every cannabis plant starts as a seed, and the seed decides 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 wasted 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 separates a good seed from a poor one, and how to store and germinate them properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or mottled, solid to the touch and slightly 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, and that is why two seeds from the same pack can grow noticeably unalike. 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 exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, faster and more forgiving of less-than-ideal 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 eliminate the guesswork and the wasted space of male plants.
- Regular seeds give 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 label usually says so. Regular autoflowering seeds exist but are rare.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the goal is flower, every male plant is space, light and weeks spent on something that will be discarded, and a single missed 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 keeper from a large population frequently prefer the broader genetic spread of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Why Autos Behave Differently
Photoperiod plants remain 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: veg 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 clock set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The trade-off is that mistakes cannot be corrected 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 generally prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more useful than the strain name.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- 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.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder follows.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are reliable.
- Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Float test. Placing seeds in water and rejecting floaters is common but crude: healthy seeds often float until the shell absorbs water.
- Surface. A slight waxy sheen is typical. Splits, dents or visible mould disqualify a seed.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that crush easily are non-viable.
Cool, Dark, Dry, Still
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them still. Shifting seeds between warm and cold again and again does more harm 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 swings that trigger premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without damaging 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 in all of them: moisture, warmth, darkness and oxygen.
- 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 within a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce 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, shallowly, and give gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling permanently.
Vetting the Seller
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of uncertain stock shows up in germination rates, not on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated in plain language.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- 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 named on each product page.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
Delivery, Packaging and Replacements
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 label.
Seeds come with a germination guarantee: if any 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.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them stays an offence. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is restricted. 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.
Still Wondering?
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Can I tell the sex of a seed by looking at it?
No. Methods 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, tells you the sex.
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 similar.
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 noticeably within a year.
