Every cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance of cannabinoids and terpenes it can develop. 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 around the world. This guide covers the main seed types, how to read a strain description, what separates a good seed from a poor one, and how to store and germinate them properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are usually brown, grey or tiger-striped, firm to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a reserve of nutrients to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, which is why two seeds from the same pack can turn out noticeably unalike. Breeders reduce 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 trade that certainty for vigour, a strong taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
Almost every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Feminized seeds are bred to produce female plants very nearly every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the lost space of male plants.
- 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 imperfect conditions, typically at the cost of yield and potency.
- 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, but they mean identifying and culling males before they pollinate the females.
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 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 time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population often prefer the wider genetic variation of regular stock. And some traditional 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 switch to flowering when the light falls to around twelve hours. That gives the grower control: vegetate for two weeks or two months, shape the plant, then flip 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 stay 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 stressed autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a fixed footprint generally 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 show you what to expect in aroma, structure and temperament far better than any marketing copy.
- 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.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- 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 indicators are worth knowing.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould rule out a seed.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Float test. Placing 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 good sign; seeds that collapse easily are dead.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics make small seeds.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- 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.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either temperature on its own; open 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.
Cracking the Shell
Each grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can drown.
- Move them to a moist paper towel within a closed container, or directly into a starter pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds produce a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light once 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 reputable seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Pack options. Flexible pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
- Breeder transparency. A trustworthy seller lists 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 named on each product page.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started by the recommended method, Bud Weed Seeds sends a replacement for it. The request 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 varies sharply by country. In many European countries seeds are traded legally as collectors’ items or for hemp purposes, while germinating them stays an offence. 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 import 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 read as legal advice.
Quick Answers
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently far longer. Kept in a warm drawer, viability drops sharply within a year.
Are autoflowering seeds less potent?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency in good lines is similar.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
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 transplanting. Genuinely dead seeds are rarer than mistakes in the process.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
