Every cannabis plant begins as a seed, and the seed decides 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 produce. Choosing well at this stage saves months of lost effort later. The market has grown 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 distinguishes a good seed from a poor one, and how to store and germinate them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically brown, grey or mottled, firm to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve 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 turn out noticeably different. Breeders narrow that variation by working 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.
The First Decision: Seed Type
Nearly every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, faster and more forgiving of imperfect conditions, typically at the cost of yield and potency.
- Regular seeds give male and female plants in about equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they require identifying and culling males before they pollinate the females.
- 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 wasted 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.
Males: Asset or Liability?
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 thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic spread 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 hard to justify.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light drops to around twelve hours. That hands the grower the decision: veg for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is 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, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- Lineage. The parent strains tell you what to expect in smell, structure and growth habit far better than any marketing copy.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is usually 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.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few indicators are worth knowing.
- Surface. A faint waxy sheen is normal. Splits, dimples or obvious mould rule out a seed.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent 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 give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Float test. Placing seeds in water and discarding floaters is common but crude: healthy seeds often float until the shell absorbs water.
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 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 dangerous unless the seeds are bone dry.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either temperature on its own; take out the container as rarely as possible.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that start premature germination or mould.
Cracking the Shell
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. Any 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.
- Wait. Most seeds show a taproot inside two to five days; some take a week or more.
- Once the taproot reaches 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 broken one often stalls the seedling permanently.
Vetting the Seller
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of uncertain stock shows up in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Pack options. Multiple pack sizes let you to test a strain before committing; Bud Weed Seeds offers 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 spelled out in plain language.
- Storage on their end. Check how stock is stored. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when germinated by the recommended method, 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 separate from the law on cannabis itself, and it differs widely by country. In many European countries seeds are traded legally as collectors’ items or for hemp purposes, while germinating them stays an offence. In other places both buying and growing are allowed under licence or within personal limits, and in some countries possession of seeds alone is prohibited.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is not permitted. 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.
Still Wondering?
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds sprout well for two to three years and frequently far longer. Kept in a warm drawer, viability drops noticeably within a year.
Why did a seed fail to germinate?
The most frequent causes are too long in water, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are rarer than grower error.
Are autoflowering seeds weaker?
Modern autos are far closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency in good lines is similar.
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.
