Any 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 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 separates a good seed from a poor one, and how to store and start them properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of energy to power 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 grow noticeably different. Breeders narrow that variation by stabilising a line over many generations, but some range is expected 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.
The First Decision: Seed Type
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more forgiving of imperfect conditions, typically at the cost of yield and potency.
- Regular seeds produce male and female plants in about equal numbers. They are favoured 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 produce female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the wasted space of male plants.
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.
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 weeks spent on something that will be discarded, 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 select a keeper from a large population frequently 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 difficult to defend.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants remain in vegetative growth as long as they receive long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then flip 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 cycle from seed to harvest is much shorter, the plants remain small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing 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 most of it is more informative than the strain name.
- 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.
- 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.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing text.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
A Quick Viability Check
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould rule out a seed.
- Float test. Placing seeds in water and discarding floaters is popular but unreliable: fresh seeds often float until the shell takes on water.
- Shell. A hard shell that does not give under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored correctly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; take out the container as seldom as possible.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container beats a clear one.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that start premature germination or mould.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
Getting a Taproot
Each grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot within 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 once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one often stops the seedling for good.
Reputable Source, Reliable Sprouts
Seeds are only as good as the supplier, and the difference between a reputable seed bank and a reseller of uncertain stock appears in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Storage on their end. Check how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Breeder transparency. A trustworthy 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 shown on each product page.
- Pack options. Multiple pack sizes let you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers 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 a seed fails to sprout within 14 days of delivery 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 varies widely by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them remains 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 banned.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is not permitted. 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 sell CBD-only strains?
Yes. The catalogue has high-CBD lines with negligible THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Are autoflowering seeds less potent?
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 comparable.
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 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. Genuinely dead seeds are less common than mistakes in the process.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and frequently much longer. Left in a warm drawer, viability falls noticeably within a year.
