Any cannabis plant begins 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 balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 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 germinate them properly.
What You Are Actually Buying
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually brown, grey or mottled, firm to the touch and slightly glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store of nutrients 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 working 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 taproot and the chance of a standout plant.
The First Decision: Seed Type
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, quicker and more forgiving of imperfect conditions, typically 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 eliminate the guesswork and the wasted 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 make their own seeds, though they require identifying and removing males before they pollinate the females.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the bulk 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 thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds earn their place in three situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population often prefer the broader genetic spread of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants remain in vegetative growth as long as they get long days and move to flowering when the light falls to around twelve hours. That hands the grower control: vegetate for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants remain small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and much of it is more useful than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing text.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
- 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 test, but a few indicators are reliable.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Surface. A slight waxy sheen is normal. Splits, dimples or obvious mould rule out a seed.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either condition on its own; open the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than 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.
- 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.
- 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 starter pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds produce a taproot within 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 as soon as the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stops the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of unknown stock shows up in germination rates, not on the website.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year drop viability before they reach you.
- Pack options. Flexible pack sizes let you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be stated in plain language.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no mention to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of arrival when started as described above, Bud Weed Seeds replaces it. The request requires 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 differs widely by country. In many European countries seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. In other places 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 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 jurisdiction before ordering, and nothing on this page should be read as legal advice.
Quick Answers
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 from reputable breeders is similar.
Why did a seed fail to germinate?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than mistakes in the process.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, ridges or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
How long do cannabis seeds last?
Kept cool, dark and dry, most seeds germinate reliably for two to three years and frequently far longer. Left in a warm drawer, viability drops 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, alongside balanced and THC-dominant strains.
