Every cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage saves 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 germinate them properly.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically brown, grey or tiger-striped, solid to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store 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 turn out noticeably different. Breeders narrow 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 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 most important decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they require 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, quicker and more tolerant of imperfect 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 normally says so. Regular autoflowering seeds exist but are rare.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem entirely.
Regular seeds justify their place in three 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 sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
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: veg for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants remain small, and they can be run under long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height often succeed with autos; growers chasing maximum yield from a given footprint generally 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.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Use 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.
- 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 uses.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Surface. A slight waxy sheen is normal. Cracks, dents or obvious mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
- Float test. Placing seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell takes on water.
Long-Term Seed Storage
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 fluctuation.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that start premature germination or mould.
- 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 bone dry.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as seldom as possible.
The First Five Days
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or straight into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds produce 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, shallowly, and give gentle light as soon as the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one frequently stops the seedling permanently.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of uncertain stock shows up in germination rates, rather than on the website.
- Pack options. Multiple 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. Check how stock is kept. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
- Breeder transparency. A good seller names 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 named on each product page.
- Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
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 outside.
Every pack comes with a germination guarantee: if any seed fails to germinate within 14 days of arrival when germinated as described above, Bud Weed Seeds sends a replacement for it. The request requires the order number and, in most cases, a photo.
Seeds, Plants and the Law
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. 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 send orders to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
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, tells you the sex.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and often far longer. Left in a warm drawer, viability falls 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 generally smaller because the plants are smaller, but potency in good lines is comparable.
Why did a seed fail to sprout?
The commonest causes are too long in water, cold, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are less common than mistakes in the process.
