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 saves 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.
Anatomy of a Seed
A cannabis seed is a tiny, 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 start: a root tip, two cotyledon leaves and a reserve of energy to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, which is why two seeds from the same pack can turn out noticeably unalike. Breeders narrow that variation by working a line over many generations, but some range is normal in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional 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 first decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
- 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 lost space of male plants.
- Regular seeds produce 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 removing 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 uncommon.
Males: Asset or Liability?
For the bulk 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 overlooked male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are only 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 get long days and move to flowering when the light drops to around twelve hours. That hands the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a clock set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a fixed footprint generally choose 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 informative than the strain name.
- 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Read them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing copy.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are reliable.
- Surface. A faint waxy sheen is normal. Cracks, dimples or visible mould disqualify a seed.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Shell. A firm shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are dead.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous 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. Moving seeds between warm and cold again and again does more harm than either condition on its own; take out the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that start premature germination or mould.
The First Five Days
Each grower has a preferred method, but the requirements 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. Longer and they can drown.
- Move them to a damp paper towel within a closed container, or directly into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot inside two to five days; some need a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and provide gentle light as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stops the seedling for good.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Breeder transparency. A good seller names 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, discretion, and what the seller does when seeds fail to germinate should all be stated up front.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.
Delivery, Packaging and Replacements
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 outside.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of delivery when germinated by the recommended method, Bud Weed Seeds replaces it. The claim needs 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 varies sharply by country. In many European jurisdictions seeds are sold legally as souvenirs 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 possession of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where import 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.
Questions Growers Ask
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Kept in a warm drawer, viability falls sharply within a year.
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, as well as balanced and THC-dominant strains.
Are autoflowering seeds weaker?
Modern autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
Why did a seed fail to sprout?
The most frequent causes are too long in water, cold, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are less common than grower error.
