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 balance of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of lost effort later. The market has grown 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, 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 nutrients 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 working a line over many generations, but some spread 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 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 first decision a buyer makes.
- 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, but they require identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that make the plant to flower on age rather than on light cycle. They are smaller, quicker and more forgiving of less-than-ideal conditions, usually 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.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually 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 space, 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 problem entirely.
Regular seeds earn their place in three 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 only 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 drops to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a clock 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 run under continuous light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a fixed footprint generally prefer photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and much of it is more informative than the strain name.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder follows.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing text.
- 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.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly 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 test, but a few indicators are worth knowing.
- Surface. A faint waxy sheen is typical. Cracks, dimples or visible mould rule out a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Float test. Dropping seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell takes on water.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
Cool, Dark, Dry, Still
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that start premature germination or mould.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either condition on its own; take out the container as rarely 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 harming it; the freezer is risky 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 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 moist paper towel inside a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot inside two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stops the seedling permanently.
Vetting the Seller
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, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
- Pack options. Flexible pack sizes allow you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- 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.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no reference 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 by the recommended method, Bud Weed Seeds replaces it. The claim requires the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies widely by country. In many European jurisdictions seeds are traded legally as souvenirs 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 possession of seeds alone is prohibited.
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.
Questions Growers Ask
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency in good lines is comparable.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds germinate well for two to three years and frequently far longer. Left in a warm drawer, viability falls sharply within a year.
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 injury to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, markings 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.
