Every 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 large it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of wasted effort later. The market has grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. 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 properly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Viable 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 reserve of energy 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 grow noticeably unalike. Breeders reduce that variation by working a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get identical copies; seeds trade that certainty for vigour, a taproot and the chance of a exceptional plant.
Three Seed Types, Three Different Grows
Almost 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 yield 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.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal 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 make their own seeds, but they require 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 description usually says so. Regular autoflowering seeds exist but are uncommon.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the aim 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 sidestep that issue entirely.
Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some traditional lines are simply available 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 get long days and switch to flowering when the light drops to around twelve hours. That gives the grower control: vegetate for two weeks or two months, train the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants stay small, and they can be run 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 fixed footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and most of it is more useful than the strain name.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing text.
- 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.
- 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 uses.
- 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.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under ideal conditions. Read them as a ceiling, not a guarantee.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few indicators are reliable.
- Surface. A faint waxy sheen is normal. Cracks, dimples or visible mould rule out a seed.
- Size. Larger is not better; seed size varies by strain, and some top genetics make small seeds.
- Float test. Dropping 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 usually mature. Pale green or white seeds were harvested too early and seldom sprout.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The enemies are warmth, light, moisture and fluctuation.
- Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either temperature on its own; take out the container as seldom as possible.
- Keep them dry. A sealed container with a desiccant packet prevents 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 harming it; the freezer is risky unless the seeds are bone dry.
Getting a Taproot
Each grower has a favourite method, but the requirements 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. 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 in the low-to-mid twenties Celsius.
- 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 breaks the surface.
Handle 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 source, 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 try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be stated in plain language.
- Breeder transparency. A good 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 sent in plain packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of delivery when started by the recommended method, Bud Weed Seeds replaces it. The claim requires 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 widely by country. In many European countries seeds are traded legally as souvenirs or for agricultural purposes, while germinating them remains an offence. Elsewhere 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 duty to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds germinate well for two to three years and often much longer. Left in a warm drawer, viability falls noticeably within a year.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Why did a seed fail to germinate?
The most frequent causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are rarer than grower error.
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Yields 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 looking at it?
No. Claims 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.
