Any cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the balance 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 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 small, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually 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 store of nutrients to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, and that 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 exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- 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 give 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.
- Autoflowering seeds contain ruderalis genetics that cause the plant to flower 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 and autoflowering are not opposites: 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 aim is flower, every male plant is room, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a mother plant from a large population often prefer the wider 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 difficult to defend.
Why Autos Behave Differently
Photoperiod plants stay 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 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 flower on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The downside 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 after 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.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- 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.
- Lineage. The parent strains show 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 usually given as total time from seed. Check which convention the breeder follows.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a verdict, but a few indicators are worth knowing.
- Size. Larger is not a quality marker; seed size varies by strain, and some excellent genetics produce small seeds.
- Surface. A slight waxy sheen is normal. Splits, dimples or obvious mould rule out a seed.
- Float test. Placing seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell takes on water.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that start premature germination or mould.
- 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 rarely as possible.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
The First Five Days
Each grower has a preferred method, but the requirements are the same whichever you choose: 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 drown.
- Move them to a moist paper towel within a closed container, or straight 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 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 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 unknown stock shows up in germination rates, not on the website.
- Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year lose viability long before they reach you.
- 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.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be stated up front.
From Checkout to Letterbox
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 any seed fails to germinate 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.
Seeds, Plants and the Law
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them stays an offence. In other places 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 know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
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.
Are autoflowering seeds less potent?
Modern autos are far 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.
Why did a seed fail to germinate?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during transplanting. Genuinely dead seeds are less common than mistakes in the process.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
