Every cannabis plant starts as a seed, and the seed settles 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 grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. This guide explains the main seed types, how to read a strain description, what distinguishes a good seed from a poor one, and how to store and germinate them correctly.
Anatomy of a Seed
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 start: a root tip, two cotyledon leaves and a store 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 turn out noticeably different. Breeders narrow 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 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 produce male and female plants in about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they mean identifying and culling males before they pollinate the females.
- 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 lost space of male plants.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of imperfect conditions, usually at the cost of yield and potency.
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 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 thrown away, 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 hunt for a keeper from a large population often prefer the broader genetic variation 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 stay in vegetative growth as long as they get long days and move to flowering when the light drops to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, shape 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 run under long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often do well with autos; growers chasing maximum yield from a fixed 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.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing copy.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder uses.
- 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Expressed 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 indicators are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Surface. A faint waxy sheen is typical. Cracks, dents or obvious mould disqualify a seed.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell absorbs water.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The threats are heat, light, moisture and change.
- Keep them still. Moving 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 cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that start premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
Getting a Taproot
Every grower has a favourite method, but the requirements 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 damp paper towel within a closed container, or directly into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds produce 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, shallowly, and give gentle light as soon as the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stops the seedling permanently.
Reputable Source, Reliable Sprouts
Seeds are only as good as the source, and the difference between a serious seed bank and a reseller of unknown stock shows up in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- 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 shown on each product page.
- Pack options. Multiple pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be spelled out up front.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year lose viability long before they reach you.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no mention to the contents on the label.
Seeds come with a germination guarantee: if a seed fails to sprout within 14 days of delivery when started 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 differs widely by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays illegal. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Are autoflowering seeds less potent?
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.
Why did a seed fail to germinate?
The most frequent 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 rarer than grower error.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
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 evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds germinate well for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply within a year.
