Every cannabis plant begins as a seed, and the seed settles 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 develop. Choosing well at this stage avoids 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 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 correctly.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo enclosed 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 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 unalike. Breeders reduce that variation by stabilising 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.
Regular, Feminized, Autoflowering: The Big Three
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 give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they mean 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 yield 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 opposites: most autoflowering seeds sold today are also feminized, and the description 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 time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue 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 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 stay in vegetative growth as long as they get long days and switch to flowering when the light falls to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants stay small, and they can be run under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed 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.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and much 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.
- Lineage. The parent strains show you what to expect in aroma, structure and temperament far better than any marketing copy.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
- Yield estimates. Expressed 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a guarantee.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few indicators are worth knowing.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Surface. A slight waxy sheen is normal. Splits, dimples or obvious mould rule out a seed.
- Float test. Dropping seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell takes on water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and fluctuation.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
- Keep them still. Shifting seeds between warm and cold again and again does more harm than either temperature on its own; open the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that start premature germination or mould.
Cracking the Shell
Every grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a starter 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 is about a centimetre long, plant it root-down, just below the surface, and provide gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling permanently.
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.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability long before they reach you.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to germinate should all be stated in plain language.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- 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 shown on each product page.
What Happens After Checkout
Bud Weed Seeds ships 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 any seed fails to germinate within 14 days of delivery 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 sharply by country. In many European countries seeds are traded legally as souvenirs or for hemp 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 import of cannabis seeds is not permitted. It is the buyer’s responsibility to check 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?
Stored cool, dark and dry, most seeds germinate reliably for two to three years and frequently much longer. Kept in a warm drawer, viability drops noticeably within a year.
Are autoflowering seeds less potent?
Modern autos are far 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 similar.
Why did a seed fail to germinate?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are less common than mistakes in the process.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with minimal THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
