Any cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds 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 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 start them properly.
What You Are Actually Buying
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically brown, grey or tiger-striped, firm to the touch and slightly 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 unique combination of its two parents, which is why two seeds from the same pack can grow noticeably different. Breeders reduce that variation by stabilising a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
Nearly 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 yield 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.
- Regular seeds produce male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they mean identifying and removing males before they pollinate the females.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more tolerant of less-than-ideal conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label 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 aim 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 entirely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic variation of regular stock. And some old-school lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants remain in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That gives the grower control: vegetate for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and flower 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 long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a given footprint usually choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Read them as a ceiling, not a guarantee.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
A Quick Viability Check
Appearance is a rough guide to viability, not a verdict, but a few indicators are reliable.
- Surface. A slight waxy sheen is typical. Splits, dents or obvious mould disqualify a seed.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are dead.
- Float test. Placing seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that start premature germination or mould.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as seldom as possible.
The First Five Days
Every grower has a preferred method, but the requirements 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 damp paper towel inside 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 inside 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 emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling for good.
Reputable Source, Reliable Sprouts
Genetics 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.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be stated in plain language.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year lose viability before they reach you.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Breeder transparency. A trustworthy seller lists the breeder for every strain. Bud Weed Seeds carries 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 sent 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 germinated as described above, Bud Weed Seeds replaces it. The request needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it varies widely by country. In many European countries seeds are traded legally as collectors’ items or for hemp purposes, while germinating them stays illegal. Elsewhere both buying and growing are allowed 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 import of cannabis seeds is restricted. It is the buyer’s duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Are autoflowering seeds weaker?
Current autos are far 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 similar.
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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, most seeds germinate well for two to three years and often much longer. Kept in a warm drawer, viability falls sharply within a year.
