Every cannabis plant starts as a seed, and the seed settles 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 develop. Choosing well at this stage saves months of lost effort later. The market has expanded 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 separates a good seed from a poor one, and how to store and start them correctly.
What You Are Actually Buying
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Viable seeds are typically 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 energy to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, and that is why two seeds from the same pack can turn out noticeably unalike. Breeders reduce that variation by stabilising a line over many generations, but some range is normal in any seed-grown crop. Clones are the only way to get exact copies; seeds trade 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.
- Feminized seeds are bred to yield female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
- Regular seeds give male and female plants in about equal numbers. They are favoured 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 flower 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 and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the majority 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 sidestep that problem entirely.
Regular seeds justify their place in a few situations. Breeders need males to provide 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.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay 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 fits the space.
Autoflowers ignore 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 shorter, the plants remain small, and they can be grown under continuous 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 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 informative than the strain name.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
- 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. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
A Quick Viability Check
Appearance is a loose guide to viability, not a verdict, but a few signs are reliable.
- 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, dents or visible mould rule out a seed.
- Float test. Placing seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell takes on water.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either condition on its own; open the container as seldom as possible.
- 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 bone dry.
- Keep them dry. A sealed container with a desiccant packet stops the humidity swings that start premature germination or mould.
Cracking the Shell
Every 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 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 small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. 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, shallowly, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling for good.
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 shows up in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Breeder transparency. A trustworthy seller names 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.
- Pack options. Flexible pack sizes allow you to try a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated up front.
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 outside.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of arrival when started by the recommended method, Bud Weed Seeds replaces it. The claim requires 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 jurisdictions 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 restricted. It is the buyer’s duty to check the rules in their own jurisdiction 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 over-soaking, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are less common than mistakes in the process.
Are autoflowering seeds weaker?
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 in good lines is similar.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD 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. Methods based on shape, markings or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
