Every cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts 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 expanded enormously, and https://budweedseeds.com now carries 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.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Mature seeds are usually 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 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 grow noticeably different. Breeders narrow 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 exchange that certainty for vigour, a strong taproot and the chance of a exceptional 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.
- 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 require identifying and culling males before they pollinate the females.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, faster and more forgiving of less-than-ideal conditions, usually at the cost of yield and potency.
- Feminized seeds are bred to produce female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the lost space of male plants.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description normally 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 room, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds earn their place in a few situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population frequently prefer the wider genetic spread of regular stock. And some traditional lines are only sold in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
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 gives the grower the decision: veg 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 timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants stay small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given 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.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a promise.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder uses.
- Lineage. The parent strains tell you what to expect in smell, structure and temperament far better than any marketing copy.
- 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 heavily dependent on the grower. Use them to compare strains from the same breeder, not across breeders.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few signs are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Surface. A faint waxy sheen is normal. Splits, dents or visible mould disqualify a seed.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
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 again and again does more harm than either condition on its own; take out the container as rarely as possible.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
Getting a Taproot
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 damp paper towel within a closed container, or directly 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 take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and give gentle light as soon as 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.
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, not on the website.
- 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.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be spelled out in plain language.
- Pack options. Multiple pack sizes let you to test 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 drop viability before they reach you.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are sent in plain packaging with no reference to the contents on the outside.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of arrival when started as described above, Bud Weed Seeds sends a replacement for 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 jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains 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 banned.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is restricted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
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. Truly dead seeds are rarer than grower error.
Does Bud Weed Seeds stock 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 far closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency from reputable breeders is similar.
How long do cannabis seeds last?
Kept cool, dark and dry, the majority of seeds germinate well for two to three years and often far longer. Kept in a warm drawer, viability falls noticeably within a year.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
