Every cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of lost 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 correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or tiger-striped, firm 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 nutrients to power 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 unalike. Breeders narrow 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 standout plant.
Regular, Feminized, Autoflowering: The Big Three
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 carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are more compact, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
- Regular seeds give male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they require identifying and removing 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 eliminate the guesswork and the lost space of male plants.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label usually says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the goal 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 avoid that issue completely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic spread of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they receive 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, train the plant, then flip flowering when it suits 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 remain small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a fixed footprint generally choose 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.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- THC and CBD ranges. Stated 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 counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder follows.
- Yield estimates. Given 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.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, 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 faint waxy sheen is typical. Splits, dents 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.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are dead.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: healthy seeds often float until the shell absorbs water.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage 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.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
- Keep them dark. Light degrades the embryo over time, so an opaque container is better than a clear one.
Cracking the Shell
Every grower has a preferred method, but the essentials 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. Longer and they can drown.
- Move them to a damp paper towel inside a closed container, or straight into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot within two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one often stops the seedling for good.
Vetting the Seller
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock shows up in germination rates, not on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year lose viability long before they reach you.
- Pack options. Multiple pack sizes allow you to try a strain before committing; 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 named on each product page.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no mention 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 replaces it. The claim needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are sold legally as souvenirs or for hemp purposes, while germinating them stays an offence. In other places both buying and growing are permitted 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 importing of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Can I tell the sex of a seed by examining it?
No. Methods 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.
Why did a seed fail to sprout?
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 transplanting. Genuinely dead seeds are rarer than grower error.
Does Bud Weed Seeds stock 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.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and often far longer. Left in a warm drawer, viability drops noticeably within a year.
Are autoflowering seeds less potent?
Current autos are far closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency from reputable breeders is similar.
